the clearance is there, the trouble is the stock inner fenders doesn'r "rest" in the wider fenders and as such are getting "adjusted" by the tyres  :wink:

....When you say "stock inner fenders" don't you mean the stock wheel arch linings?

I know this is something I have asked you about and you haven't done anything yet to mod them to fit/join the carbon fenders. Surely not a difficult mod?

You're right RR, it's the stock wheel arch linings, actually i have a plan  :party:
I'll buy 2 new wheel arch linings, split them longitudinal, use the outer parts, the old ones will get the outer 10-15% removed and then cut across to app. the middle, then the new ones will be put in and marked against the old and then both parts will be put together.  :pomppomp:

Carrera2RS:
I have experimented a little with tyre pressures, currently running 36F, 34R

The combination is very good, balance is now very close to neutral. I am currently having no arch problems cornering hard. I might put the order of a set of 8x18 ET 50's on hold (5 mm further in per side than my current ET45's)

I will experiment over the weekend a little, I may try adjusting ride platforms a little up 1/2-1 turn F, up 1/4- 1/2 turn at the rear this will add 2-3mm front and back. This should put the heights to 340F, 325R.

Then given my rear toe was 2mins total, I am wondering how reducing toe a small amount from 13 mins on the current set up might feel (should increase oversteer a touch) I'll talk to Tony and see what he thinks.

I'd be interested to those who have settled on a set up have the car set to. The other option might be to add 15mins of camber at the front and back to 2 deg 15 mins F, 1 deg 45mins back.

I like the balance of feel, weight and stability at the front with parallel tracking. I have more confidence at higher speeds than a touch of toe out on the previous setup.

rich83:
IIRC a straighter rear setup should loosen the rear up.

My rear toe is a little straighter than yours being the same as bergs... 10mins total.

fuscobal:
Carrera, what brakes do you have ? 8x18 is good but is ET50 enough if one wants to go with some Ap racing 356mmx32 6 pots ? Wouldn't ET45 be better in this respect (maybe succed to avoid spacers) ?

I'm running like -2.3 camber in front and close to 0 toe and -1.5 camber on the rear and 10mins toe in. Also don't have any uneven tire wear problems !
