I’m surprised that you’ve got more negative camber at the front than the rear… but they are front wheel drive I suppose…
I can imagine that “cheap” bill still hit the wallet hard! But it’s good to know that ittl be put to good use on track. I hope to see some videos of your runs!

Front bias is preferable on these, the rear tends to be super grippy compared to the front. You don't often see the back coming out on these like on light weight hatches like clios and civics. The weight has something to do with that I imagine.
No wasn't cheap at all but less painful than imagined :grin:

The camber setup seems good. With road tyres 34 psi is preferable. I use 32 psi with my AD08R. :smiley:

Loving the MK1s in that Retro Resus pic :happy2:
I just run the tyre pressure on the petrol flap, which is 36psi I think.
1400kg, blimey, didn't know they were that chubby. Is yours DSG? I'm sure I read in the owners manual that the kerb weight is around 1340kg, but that's for the manual gearbo though. I think DSG adds around 25Kg iirc.

Yeah I think il experiment with 30-34psi hot pressures and see what works. I stuck to 35 psi hot on standard good year asym 5's which worked best, any lower they would get too hot and struggle. Ns2r's have a much stiffer sidewall and shouldn't overheat like a daily driver road tyre so should be able to run lower pressures with success theoretically.
No mine is manual but does have a sunroof which I imagine is about 20kg, heated seats could be extra weight as well I'm not sure, but with lighter suspension bits, no radio, no fog lights, no spare wheel or tool kit. Yeah I hope that was with the ballast included, got a week off soon-ish so will try and venture out and get it on a weigh bridge, as I am curious!
As lots of owners I've got a duct from the fog light/fog light area pointing to the intake filter. Had this in for a while now just because I had the ducting lying around doing nothing so thought may as well but I've always thought surely it does sweet naff all.
But today I decided to stick a hair dryer towards the duct at various angles and distances and fairplay the airflow does get up to the filter quite efficiently! Surprised the duct I've had installed for months actually works :grin:
Also mounted a fire safety stick and radio blank, yes before you ask it is 100% not straight, that's what happens when you just drill holes without marking up prior :grin:

Very ghetto arch rolling attempt. Rust jack handle + hair dryer + touch up pen = surprisingly successful
Finally had its first track session in over a year at Llandow
Car performed flawlessly, I was 2nd to arrive and last on track and last to leave so gave it really good abuse. The balance of the car is sooo much better than before, just coming off throttle mid corner slightly provokes the rear to rotate nicely. What I did not expect was how much more fuel efficient the car was compared to last time, the number of consumables and work I've done on the engine I guess has probably fixed some old car fuel inefficiencies which was nice!
Map 4 (260bhp) was just so much wheel spin it wasn't that enjoyable to drive, Map 2 (~220bhp) was on the limit of wheel spin without issues and Map 3 (~240bhp) was a good compromise between the two which I stuck with. I think a quaiffe is needed now!

- Brakes performed great, my temp stickers indicated they got to between 188 and 210 degrees Celsius. Only noticed after leaving for the day that the pedal felt quite long, it is running motul rbf 660 so was surprised by that but maybe we are on the limit of the stock brakes, I could still trigger abs but only on the slow chicanes with these tyres. Being as Combe is next and a heavy braking circuit I may put some ducting in that will point to the caliper, not a great solution but the discs are cheap, I have spare race pads already waiting and if it stops brake fade going into quarry then I'm all for it. I will say though the rp-1 pads felt really awesome when they were warmed up, the pedal feel was really great, will have to check how they've worn soon but impressed so far.
The stock brakes get a terrible bashing sometimes, but I've found they're not great but you won't fly off the circuit like some will have you believe if you're running a good race pad and fluid, especially so if you're just running normal daily driver road tyres.
Pressures wise I aimed for 34 but ended up on about 33 on front and 32 on rear just because conditions changed and hot pressures dropped later on and couldn't be bothered adding more air in and bringing back down. Think this was a little low as I've got a decent amount of pick-up in the centre of the tyre left on rears which could indicate it was bulging inwards from too low a pressure. Man maths is telling me 35-33 psi is the target for these tyres on current weight.
The fronts could also be a little low on 33 as we still rolled over onto the sidewall
Overall though awesome result, it was quick and a couple people mentioned they were surprised at the pace this was lapping all day. Combe next on 8th July :smiley:
