Very budget track build

I think they bought them in. They didn't mention it being something they made at least. I think they switched to the mega bucks Verkline subframes and arms after that.

I also watched one of REPerformance's videos recently where Ryan took his MK5 down to their dyno as it's a track certified one. Apparently a lot of folk were complaining his MK5 is too fast, so must be cheating by running more power  :grin:  Sore losers  :grin:

Anyway, yeah the forces have to go somewhere when running track suspension and tyres....and when everything else stops breaking, the bodyshell itself then takes the brunt  :grin:

Yeah they've cracked a couple of those Verklin subframes mind you. I think some of the btcc cars eithe before or currently didn't even have subframes, just control arms mounted directly to the chassis.

Yeah I did see that actually. Tbh I don't think anyone does as much R&D as Darkside and Area motorsports which is why it's always one of them winning each round and everyone is else trying to grass them up for somethin :grin: that's why I'm glued to all their videos to try and get little nuggets of development info.

Ditched the ECS tuning silicone pcv hoses and opted for the genuine ones. The ECS ones were not great frankly - they were very slimey oddly just to touch and the upper one started to tear where the clamp was on. R Tech told me they were not convinced by them too. None of the big power cars have issues with oem ones so going to stick with oem now, think it's really just a case of go full catch can or keep entire pcv system oem.



Bought a 2nd set of 18 inch Monza's, but over ebay online and tbh they're in a right sh*t state. Corrosion everywhere, very annoying. I have learnt my lesson though never buy cheap wheels on the internet  :grin: I'll be refurbing them with flap discs and wire wheels to get corrosion off and then just sanding down and doing a quick paint job. These will be the dedicated track tyre set.



It got dropped off yesterday at Retro Resus. God its horrible to drive on the road now :grin: I'm sure its great up the brecon beacons and equivelant driving roads but on the m4 it's horrid :grin:

They're going to:
Delete the air conditioning
Remove majority of air bags
Shot blast and paint the rear subframe and control arms and install all SP bushes
Corner weight
Set alignment to max front camber,  O.5 degrees less rear camber, 1mm front toe out and 2mm rear toe out

I also noted on the way down the seat is way too high and too far forward despite being as far back as it will go and as low as it will go so hoping they can find a way to fix that too. I also asked for the total weight to be reported so that will be interesting to find out - my guess is about 1250kg

Yeah keep the PCV system OEM as it works spot on  :happy2:  Maybe the ECS hosing isn't oil and fuel rated as it shouldn't be slimy and tear apart easily. Proper industrial Oil/fuel rated silicon hosing is generally far more expensive than regular silicon as it has a special lining in the bore. I say 'fuel' because PCV gases have a lot of unburnt fuel in them, and petrol is a solvent to silicon, which destroys it far quicker than OEM rubber and plastic hoses.

I remember in my very naughty days of dumping the PCV gases to atmosphere via a long regular grade silicon hose pointing at the ground.....yeah....the hose turned to mush after about 6 months  :grin:

Deleting the A/C is a quality move, not sure about deleting the air bags though  :grin:

Clarkj93:
Yeah agreed, surprising as I always thought of ECS as the king of VAG tuning and that it was a shame they're only US based with a small amount of their stock making it over here but it is quite dissapointing really.

haha never considered doing that actually, I will try my best to refrain from that approach :grin:

Well AC is staying for now... there was some confusion when it was booked and time restraints meant they're going to leave it for now, not that bothered as the bill is large enough already so :grin: I might have a crack myself later in the year, just thought if I had to have it de-gassed they must as well do the whole thing. The idea of a blower and some ducting have entered my mind as replacement like this one https://www.demon-tweeks.com/uk/demon-tweeks-in-line-blower-fans-242248/ so swapping a heavy front end 10kg unit that hurts temps and replacing with a 4 inch electric blower aimed directly at the driver, logistics of that is for another time however.

I still have not picked it up yet as I've been busy but its sat waiting currently for next weekend for me. Hopefully they made a note of total weight as I forgot to ask the other day over the phone.

Josh who set it up last time and who I ran into at Pembrey last year mentioned they cannot adjust the seat as it will hurt the integrity of the seat base so they've left it for now and advised to find some universal side mounts that will have far more extreme options in terms of height available. All air bags are now gone though, they mentioned they can leave the steering wheel one in but it would never go off as the front air bags work off the oem seat belt which is now gone so may as well ditch. I know what you're saying about air bags :grin: but with a helmet no air bags is supposedly safer anyway and the amount of road miles will be very small until the car is caged with a harness anyway.

They've put the idea in my head of taking it racing, hillclimbs/sprints will definitely be on the cards for next year but they were mentioning they got have some good links in a few close to home series and can assist in getting to that point... would love to but budget is not there just yet, maybe in a couple of years. It will definitely be going in for a welded up roll cage however next year to meet regs for sprinting and they did mention they can ditch the oem seat mounts and weld in a new base thats custom fit for me so I can try and get it as far back and low as possible that is still drive-able for me and without having to re-engineer the entire pedal and steering wheel position.

I need to stop faffing about with my trying to find extra performance here and there and just focus on getting it to meet regulations, even if its slow in its class at least it is eligibile and being used rather than a fast car that sits on a private piece of land year in year out :grin:

So the focus right now and over the next 12 months will be only very cheap and free mods asside from repairs and maintenance to raise those funds which will be things like:
Build up better brake ducting
Remove any weight possible without cost that allows it to remain road legal
Any cheap/easy/free mods to allow better cooling (that actually work!)
Relocate battery
refurb 2nd set of wheels
try again to convert to solid top mounts and linear springs

Anything else is just not needed right now so I need to pull my finger out :grin:

Bit boring to have no pics I know but I have been reading and watching a lot of Julian Edgar recently on aerodynamics and would highly recommend to anyone, its made me realise just HOW MUCH can be improved on the golf and how many quite mainstream mods out there are probably hurting drag, IAT's, cooling and lift. He shows just how easy you can test this stuff yourself with about 50 quids worth of equipment, its pretty cool.

Marticus:
Looks like you're making good progress. Regarding brake ducting, this is something I'm currently playing with.

As there is not much off the shelf I'm playing with 3d scanning and am hoping to eventually have something in carbon fiber pulled from 3d printed molds.

I'm fairly confident that it's achievable, but I'm having to climb a steep learning curve with the 3d design part of things as the scans I took are too big and details for the simple program I was using in the past.

Anyway give me a shout if you have any ideas or want to coordinate, this isn't something I'm trying to profit from I'm hoping to eventually have some designs that anyone can get 3d printed directly in abs, or print molds for carbon / fiberglass.
