Title: 245s.... anyone done it?
Post by: AJP on August 17, 2017, 10:36:00 pm
Plenty of us are familiar with the gripes of a reasonably warm FWD car. Lots of fun 'rolling', but at other times scrambling for grip. Booting it in 2nd from 30mph up into 3rd (and then the speed limit) is one of those times.

I'm not talking about stock states of tune here. Any "I don't struggle for grip" responses from owners of cars running stock-ish torque don't apply to this thread, I'm afraid. And yes, we know about the ALKs, sticky rubber, coilies, and all that. Let's assume all that's done.

So, grip. Limted Slip Differential is one. AWD conversation is another. Both big money. What I've been pondering for a while is the simplest, and undoubtedly the cheapest - more tyre on the road.

Put simply:

Kerscher / SRS carbon wide front wings, apparently giving an extra 25-30mm clearance each side.

9s all round.

245s all round.

Has anyone done it? Was it worth it?

Surely the extra weight of the tyre/wider alloys will outweigh the benefit of more rubber on the road for grip. More inertia will occur.

Remember lighter wheel and tyres combo will keep the wheels planted better and will have less rebound from the suspension to keep them touching the ground quicker.

Mmmmmm, 9J Compomotive MO1890 with Kerscher wings..... the stuff of dreams.   

They are frickin heavy wheels though.   I had a set of 8x17 some years ago and they were 10.5Kg.  I hate to think how heavy the 9Jx18 is!!  I wish Team Dynamics still made the ProRace 1.  They looked superb in wide format and were very light.

I'm sure you've considered all the pros and cons but one thing in the back of my mind would be the cost to implement it is way more than getting an LSD fitted, dependent on your choice of parts obviously!

Sounds like a great project  :happy2:

More grip isn't always a good thing... but I would look at better tyres rather than wider ones.

Just do it mate.  Life is too short to procrastinate  :happy2:

Too much grip is an issue when you have drinking straws for driveshafts and gearboxes made of cottage pie, but neither apply to the GTI  :smiley:

The only thing that would deter me is how heavy the car will feel with massive wheels and tyres.

Post by: slix on August 18, 2017, 06:22:06 pm
Another thing.... when I put my new alloys on, which were 2kg lighter per corner, I noticed I had slightly more grip. The tyres stayed exactly the same, just put onto the new wheels.

Post by: AJP on August 18, 2017, 06:35:02 pm
How heavy is a BBS VZ? Say I found a wheel an inch wider that was no heavier than a VZ, it'd only be the weight of the extra tyre that'd be slowing/weighing things down.

So that begs the question - what exactly is the difference in weight between say a 225 40 18 and a 245 35 18? Negligible, or considerable?
Title: Re: 245s.... anyone done it?
Post by: pudding on August 18, 2017, 07:26:37 pm
Slix has the nail on the head....it's about how quickly the tyre can regain grip after hitting a bump.  Heavy wheels affect the damper rebound.  But you can tune that if you have adjustable suspension.

If you can find a bigger wheel that's no heavier (or preferably lighter) than stock, you'll be fine. 

Continental seem to make the lightest tyres out of the big players in my experience.  I went through all this in my Corrado days.  The combo of a 7x17 ProRace 1 + 205/40/17 ContiSport 3 was 2Kg lighter than the OEM 15" Speedlines with a cheapy 15" ditch finder  :smiley:

It is very possible to go large without the calories mate, but it's just the faff of researching weights and fitments, it can take a while!   Worth it though  :happy2:

Have you driven an R32?  If you haven't, it would give an idea of how a Golf with extra porkiness will feel.

I don't mind doing the research, that's half the fun of modding for me - having confidence in an upgrade/mod by actually understanding the science of it, rather than looking for a brand name or copying others and blindly  throwing money at things!

Completely agree with you and Slix regarding wheel and tyre weight. Adding unsprung weight would be going in the wrong direction. I suppose if I was really serious about this (at competition level or something) I'd also consider 17x9 rather than 18x9, to keep the weight closer to the hub, as well as making sure the wheels were of a mega light construction.

This gets closer and closer to proper race technology the more you define an ideal - and goes up in cost massively - but I like to think some ideas from those kind of cars can be passed down to our hatchbacks.

So, FWD race cars. What do they have to aid rotation and straight line grip? A diff, naturally, but I'm sure I've read about 'reverse stagger' - wider at the front than the back. It all makes interesting reading, anyway..!

I haven't driven an R32, Kev. But everything I've heard makes them sound a bit 'lardy' :)

Yeah all of that! Aggressive geometry, fat (light) wheels, light weight slicks, wide track (longer control arms, not spacers), camber plates, rock hard suspension, plated diffs (not torsens), ditching the interior, sequential boxes...all the good stuff  :happy2:  The one thing race cars don't care about is refinement and lifespan, so that is always something to consider with a road car.

Do you remember Fiesta XR2s? They had staggered axles, much wider front track  :pomppomp:  It worked really well as those things handled very nicely indeed.

Perhaps go wide track with TTRS control arms?

If you spent a week with an R32 and then got back into your car again, you'd be amazed at the difference.  The GTI is way more nimble.

Azev A, epic wheel.  StilAuto Sigma as well  :happy2:

Too much grip is an issue when you have drinking straws for driveshafts and gearboxes made of cottage pie, but neither apply to the GTI  :smiley:


I wasn't referring to components braking... I was trying to allude to the fact that giving a car too much grip can actually make it boring. You want a certain amount of movability.

225 with decent grippy tyres is perfectly acceptable without having to f*ck about with wide wings etc etc.

If you have not tried AD08R or R888R or any other grippy tyre then make that your first port of call.
Title: Re: 245s.... anyone done it?
Post by: pudding on August 18, 2017, 08:07:58 pm
Remember you can balance out the wheel weight penalty with lighter chassis components.  Passat alloy WBs and hubs, lighter brakes and you already have coilovers, which are lighter than stock struts. 

What about an 8x18 with 235 tyres as a compromise?

Agree with that. A different way to skin a cat and all that, but I suspect AJP's vision is as much to do with stance as it is grip.

Semi track tyres are noisy as fck though...and shyte in the wet.

I do remember the XR2. Never realised they had a wider front track, I've learnt something there!

There's maybe a compromise between a wider track in combination with wider tyres. Lots and lots of research needed for me on that one. There's always that worry that what is theoretically a performance upgrade turns out to be a downgrade in practice. But again, there's fun in learning.

The Sigma was the same design as the Azev A essentially, from what I remember? The holy grail of the Azev A was the mega-rare deep dish version. If you dig about now there are a few knocking about without the dish, but hardly any with that oldskool dish. And I reckon if you found any they'd be 4x100!

Similar design, and another thing of beauty, the OZ Futura:

You'll be having to battle with trial and fact to actually know if they'd benefit tbh, although you've more tyre to give you grip, you'll have more weight and rubbing (I'm sure you've already got a solution for this in mind though). Having just been moving; 245/35/19 and 265/35/19 alloys I can tell you they're extremely heavy and they were made by BBS for an M3.

To really get the benefit of wider tyres you need the right components in place to harvest the extra grip, you'll definitely feel an increase in cornering stability from them, but you depending on set up you could see Positive/negative or no difference at all to any track times. (If you were to track)

The main object would be maintaining grip under hard acceleration, in a straight line or exiting a corner - dialling off the lock. That's my main gripe.

Weight - yes, it'd be crucial to equal or reduce wheel and tyre weight to make this anything other than pointless. Some discussion about this earlier in the thread.

Rubbing - not an issue with the wider wings I mentioned in the original post. Without the availability of the Kerscher/SRS wings I might not have even considered this.

I agree with what you're saying about theory vs practice. While you could increase grip in general, there might be some undesirable side effects of a wider footprint (assuming all other variables like unsprung weight are kept in check). It might screw up the balance into the corner, off throttle, for example. I wouldn't want to spoil the recipe in that sense.

It'd be easy to get it wrong - increasing unsprung weight, neglecting geometry revision, etc. But there must be a way of getting it right. Or at least, moving a bit in the right direction.

Never mate. Too many sh*t drivers around making things unsafe in those conditions in the first place.

Cold, wet, dark, or any combination of those: slow and steady.

I think you are over thinking all of this then TBH. Just get some better tyres and that will do to be honest.

If you are worried about grip out of corners and you are struggling to put the power down out of corners then I would suggest you are being a bit too eager to stamp on the loud pedal. You can probably fix 95% of the problems you are trying to fix by just feeding in the power a bit more subtly.

Possibly. Although there are times when I feel it'd make a much quicker car if I could just stamp on it.

I'm on PS4 at the minute. They're brilliant in the corner. It's just those moments in the lower gears, in a straight line, where it'd be nice to just floor it and be off, instead of playing the throttle vs boost game.

I have no traction issues with PS4 in the dry.  In the wet I get the TC light flickering if I'm ham fisted with the throttle. KO3s spool faster than KO4s though, which is probably why you're having problems AJP.  Nothing really happens until 3000rpm on the KO4, by which time the car has plenty of momentum when throwing the anvil down.  Laggy turbos are actually useful in FWD applications  :happy2:

My K04 hits its spike at 2500 rpm and at 3000 rpm the boost is already stabilising at 1.24 bar. It spins the wheels if pushed hard too soon but it improves when using more track focused tyres.

If I got the wider wings I'd definitely be able to get 245s under. It's just whether it's all worth it.

I'm currently on Michelin PS4, which are really damn good. I might be tempted to try the Cup 2 like Shoduchi mentioned..

I'd try the Pilot Cup 2 first. Fitting 235/40R18 tyres would increase the diameter of your wheels a bit, so the cluster speedometer would need to be set for that as well.

Why would you want wider heavier tyres mate, I'm stuck on ko3 2+ and don't have any traction issues like I used to have of you remember me crying about wheel spin a while back?. Now I'm loving it and don't have any of the now, slight spin at times but nothing like when I had those budget rubbish tyres the car came with that's for sure!!! I'm happy with it although I've got super pro ALK and H&R roll bars which help a lot too. What's your car  specs again?.

Now I'm loving it and don't have any of the now, slight spin at times but nothing like when I had those budget rubbish tyres the car came with that's for sure!!! I'm happy with it although I've got super pro ALK and H&R roll bars which help a lot too. What's your car  specs again?.
I don't have an ALK or uprated roll bars. I'm sure these would help with grip, but maybe make things a bit too stiff (I'm on coilovers).

Uprated engine mounts should help.

Just exploring the options mate

Why not try Cup 2 on front first? That should reduce understeer as well as increasing traction.

Mmmm. Now you're talking. Remember Azev A? I doubt they'd be light enough to make this feasible, but they're one of my favourites.
the were beautiful wheels AJP my favourites and still like them if I could get them for the gti I would have lol
245's way too wide so better just to have good branded 225 or maybe 235 tyres  :grin:
A few of us showing our age in this thread mate

If I got the wider wings I'd definitely be able to get 245s under. It's just whether it's all worth it.

I'm currently on Michelin PS4, which are really damn good. I might be tempted to try the Cup 2 like Shoduchi mentioned..

The ALK and decent engine mounts, as well as decent geometry all help! 

The wheelhop must drive you mad??!  :rolleye:

It doesn't drive me mad, but it does make me wonder if there's a better way!

ALK, mounts and ARBs have always been on the to-do list. I'll see how I get on once they're ticked off.

They're essential on these cars for aggressive driving!

Get those done first, and a Gripper diff  :smiley:

Diff on public roads is 98.5% waste of time. Great for the 1.5% but a lot of money for those moments.

imho AJP the roll bars and additions don't give you a stiff ride as you put it as I'd be the first to moan like a beech tree  :signLOL:

Updated Engine mounts will give to a headache  :doh:

Lol, so is a GTI. Remind us why you have one again?  Seems like you're anti every mod and people asking questions these days.

Just the voice of reason mate. I have driven a GTI with a diff and it didn't make me think "ohhh I must spend 2000 quid getting one fitted"

If I was tracking my GTI then it would be a no brainier.

Little bit of google...potentially you can go to a max of 245 on an 8" rim. Your options are the 235/40/18 or 245/35/18 both of which give a 1.2% difference in rolling diameter which is liveable with in terms of your speedo, don't know if this would upset the ABS sensors or not. SO you could go 10mm wider on a 235, and 5mm inner/outer increase shouldn't give you rubbing issues. Kinda expensive experiment though.
Thank god stretching ridiculously under sized tyres on 10" wide rims has faded away, they've probably all written off their cars.
