Very nice
My dad has a facelift octavia.
I got him go to Alex's and put all the super pro bits on it.
Can't help thinking yours needs 18 inch wheels but it's what you like ultimately.
nice and cheap

Pollybushed the entire underside of the car front and rear. ECP got me the bushes for a considerable amount less than they are available on eBay.

This is not by any shot, a nice job...... Very heavy work and extremely time consuming. With most bushes seized solid and having to be cut and chiseled out.







Obviously after refitting the subframes, the wheels were pointing at all angles! So.....





Front camber is showing -1.5 on both sides
Rear camber set to -2.0 as the cars use will now be solely for fast road/ track...

So what difference do they make,

Well the car feels more stable in higher speed corners, and much more composed over uneven surfaces which I didn't expect!
I think the mk5 platform can feel particularly floaty/jiggly when pushed at speed, the change in bushes really has made a vast improvement, making the car feel far lighter than it is.

It's a modification I would certainly recommend, but only if you intend to keep the car for a considerable time, to justify the cost and effort, neither of which being small.

Bluewaffle Octavia vRS MKII Track!

Had a great time at the ring. Killed the stock exhaust, so fitted a miltek turbo back non res. nqsbbk performed incredibly! And all other mods like bushes etc no doubt made the job of attacking the green hell far easier. Car has been sent to the body shop for some work on the arches for clearance, and some front bumper mods.










Always wondered what a mk2 Vrs would look like with full aero, so I'm going to find out......

So, had a good weekend with the car having not had it with me for near a month.





While in the bodyshop, aside from the obvious modifications, the car has had a lot of material removed from inside of the arches and the strut tower caps cut off to allow for adjustment of the coilovers that are on route.

Car is driving well and performed faultlessly at curborough today,  if a little underdamped. Over the coming weeks a lot is planned to be changed to shift the focus totally towards track use.

Modified scuttle and strut towers coming into their own now the new coilovers are on. Car is close to how i want it chassis wise, collected my new seats, and sizing up a few other bits to finish the interior.... Or lack of.




Carbon fixed seats. Takata 4 point harnesses. Custom seat subframes. New whiteline 24mm front roll bar arrived today, chassis is near completion!




Had the front subframe off today to swap the front roll bar, only to realise whiteline have sent the wrong one!

So.... Feel like having a little bit of a rant, regarding the "identity" of modified cars. TRAX is dubbed a performance car show, and for that reason, is the only car show I have attended for a long time. The lack of cars modified for "performance" was frankly depressing... I can appreciate the work that goes into a stanced car, but it is not my thing even remotely, so a car show that claims to not be about that, but then litters every stand with exactly that kind of car, is frankly, stupid.

To make things worse, I had booked track time prior to going, but the front roll bar developed a horrific knock en route, and with no tools to hand, I couldn't even disconnect it to get on track. The fact that I couldn't even give the track slot away, summed up the majority of attendees.






In the short term I am chatting with whiteline about possible causes. I have also finally decided to order a tyrolsport front subframe deadset kit. Aside from bracing, the chassis of the car will be complete. I have a return trip to the Nurburgring booked for the 10th of October.

Right.....

I think sometimes when building a car, with an ultimate aim in mind, you have to start with something as close to your intentions, before starting the build.

I haven't done that....

I have had my octavia for nearly 3 years, and until only relatively recently, I left it near standard.

I wanted a fast road/track car. In my opinion, this is not  an ideal target for a MKV platform car to achieve.

So, I pollybushed the entire chassis prior to going to the Nurburgring in May, fitted the NQSBBK and with the coilovers and rear roll bar that were already on there, I had a go. Car performed well, but the track revealed some weaknesses. Mainly the OE exhaust which snapped off from the turbo on the last lap, and left me with a 10 hour drive home with NO exhaust. I replaced this with a full milltek system which luckily I had already purchased as I had intended to upgrade.

The suspension was so soft, that the car was rubbing its head off when cornering, the arches were modified as much as possible for clearance, and I confess, I got carried away while it was in there, creating the visual monstrosity the car is now. I fitted whiteline front roll bar, which helped considerably. And a nice set of BC coilovers, with front camber adjustment and adjustable damping. These, however, created their own issues. Running the car at the correct spring rate and ride height, caused contact between roll bar and control arm, and occasional contact between body and driveshaft......

The front subframe had been creaking for a while, so i ordered a tyrolsport locking kit for the subframe, and a pair of adjustable droplinks. Hoping this would tackle both issues at once. It didn't... And the subframe locking kit is the biggest fight I have ever had fitting aftermarket components to a car, there is absolutely zero tolerance when fitting, the subframe is literally mm perfect to centre, great when its done, but a real challenge to achieve.

So the shorter links didn't help, so i fitted some superpro roll centre correction ball joints. No more bottom arm contact, but still driveshaft issues. Booked the car in with a good friend to have the chassis notched. Before this could be done, however, the driveshaft had seen more than its lion share of abuse, and the CV joint exploded. While at it, I replaced the shaft entirely with a solid shaft from a diesel, identical length and weight, but thinner. The car could then have the notch done.







As the car stands now, the chassis prep i started back in may, is now only just coming to fruition. And believe me, there has not been a weekend free that I haven't had to mess about in some way or another fettling the car.

What have I ended up with....

Polybushed front and rear axles with anti lift
Whiteline 24mm adjustable front and rear anti roll bars
Oz superturismo 17x8j et35
Goodyear eagle f1 225/45/17
BC Racing BR Coilovers 30 point adjustable damping, 10kg front 12kg rear spring rates,
Camber adjustable pillowball front top mounts
Porsche Boxster s calipers, dimpled and grooved disks, ferrodo pads
Braided front and rear HEL brake lines
Arch liners removed
Arches modified for clearance
Front Strut tops and scuttle modified for top mount access
Interior stealth strip
Carbon Recaro profi side mount seats
Custom seat subframes, fixed passenger seat, drivers seat on runners
Diesel drivers side drive shaft
Tyrolsport front subframe deadset kit
Adjustable front droplinks
Superpro front rollcentr/camber adjustable ball joints
Chassis notch

The car of course, now handles extremely well, and will **** an inside rear wheel fairly consistently through fast corners. Something a MKV platform car will only do normally just before it lands on its roof. But it has not been without sacrifice, and the car so far has cost a small fortune. I will ofcourse, be continuing the build, as I have the last few bits for the K04 conversion to gather, and the car will be a fairly well rounded package. I have another trip to the Nurburgring in October, which will be a nice chance to test the car's progress, and also set the roll bars and suspension stiffness up.

My advice to anyone wanting to build a fast road car, who has a MKV platform car, frankly, would be sell it and buy something else.... I certainly wish I had.

Fresh back from the Nurburgring, this is the cars second venture there, and a hell of a lot has changed chassis wise since the last trip. I had the alignment set for the 10 thousandth time prior to going and one little thing that made a great difference to turn in was being able to widen the front track. Using the superpro ball joints at maximum neg camber, and the top mounts adjusted to reduce it, effectively pushes both top and bottom of the wheel outwards, while still maintaining around -1.5 camber. The scope for adjustment from damping, roll bars and geo makes all of the heartache at least count for something! I think a few more track days are needed before I decide the suffering was worth it!









So, now the winter is approaching, I'm hoping to get one, maybe two, more track days in before the car gets rested and I finally take the plunge and get the K04 on. After that, the DTM style will be in full swing, front splitter redesign, wide arches and slicks.

In preparation for a lot more track work next year, and in keeping with my OCD over the car and spec, I've picked up another set of O.Z Superturismo's in identical specs to my current wheels. (5x112 17x8 ET35) These will be refurbished, probably remain silver, and have some track rubber fitted in the new year.



This is now up to date as of Nov '15, for clarity the car was bought in Jan '13....

Thanks for reading guys,

Dale

Nice write up there.  :drinking:

I wonder if anyone has Googled 'blue waffle' yet?

On my vRS I run the TT front hubs, wishbones and steering rack.  This gives around 12-15mm extra track, then I run Ohlins with Ground Control top mounts to achieve -3 degs camber on the front.  It works a treat.  Just need to find some wider front wings then I will be happy.

I call it that because I wouldn't wish the car on my worst enemy... Lol

The cast hubs and control arms have been on my wish list for a while, my porsche brakes are up for sale at the minute and I'm planning to get a more track focused brake setup. 6 pots and 2 piece discs. The cast hubs and arms will do me a favour in keeping the unsprung weight down will have to have a look at your car mate, got a thread?

Not updated it for a while.

Epic.... I will be reading this start to finish when I've got the ipad out.

Few questions for you bud, theres a guy selling a southbend flywheel on here that I'm going to purchase, any positive feedback on them? And what clutch would you recommend?

Do you have the front and rear hubs from a TT? Are the bushes the same as the OE octavia items in location and size? Hoping to just swap my polybushes into the new hubs. Obviously the front isn't bushed on the hub.

I don't have anything positive to say about Southbend clutches.  I've removed three in the past year that were causing problems and replaced with Helix.  What power do you aim to run and will you be launching?

To do the front TT hubs you also need the wishbones, ball joints, driveshafts, steering rack.

Rears are a pain too.  They bolt straight up but you need around £100's worth of new nuts, bolts and washers.  Will give 12mm preside of extra track at the rear.

Think s3 hubs and control arms will do then. Majority of the unsprung weight is there.

Rear hubs will still probably be something i will do though.

Will be running around 350-400bhp and similar torque. Do you know of a clutch thats compatible with their flywheels?

Cheers mate,

Dale

I think only SB stuff fits.  The 'Silent' single mass isn't silent at all.  I'm fairly sure that SB got their measurements wrong as the main reason for me removing the kits was dragging and not being able to change gears.

All you need is the Helix organic clutch for a dual mass flywheel.  We run them over 400lbft fine.  If you want something that will help the engine rev then go for the lightweight flywheel kit.
