Favourite geometry setup and tyres

[Laurence Gibbs]

It would be nice to know what set up' s you are using. Here' s mine:

Camber -1.30 front -1.45 rear previous -1.45 -1.30 on front now dialled to -1.30 for both fronts hpefully causing less inside tyre scrub on wheel that was -1.45
castor Factory setting
Toe Factory setting
roll bar front p3 or middle
roll bar rear p3 or full stiff, moved from P2 to hopefully dial out some understeer!
+ strut brace and rear spacers

Tyres Pirrelli Pzero assymetrico rear and directinale front.
yet to see how this new set up works on track. I will keep you all informed.

Laurence,
Same tyres, wearing well though running lower than quoted pressures.
Strut brace & rear spacers, more negative on the back than you, a/roll bars on 2 & 2. Car is generally very neutral, driver ineptitude often results in to much understeer on slow corners! When I' ve fixed that I' ll fiddle about with the settings.

Good question Laurence.

Cuppie:

Camber -1.46 front 1.25 rear
caster 4.28
Toe Factory 0.13
roll bar front -rear hole
roll bar rear -middle hole

+ strut brace and rear spacers

Tyres -anything I can blag!!

Handling neutral -it' s a joy to drive and when u get it right on a corner steering input is minimal...............no white knuckle needed!

" Pirrelli Pzero assymetrico rear and directinale front."

For the P0 System,Pirreli advize assymetrico on all four for track day use. The Direczionale are principally for road use to clear the way thru water for the rear tyres. See what you think, this set up was ' OK' on my old C4, but not brilliant -was better on Assymetrico on all 4.

Re tyres. Yes I have heard thisl. But front asymetricos no longer available in RS sizes. I know there are still a few languishing on a few tyre suppliers shelves but my supplier could not find any. And think how old these last ones must be! I think the corso' s are also designed to go with the asymetrico rears and are more suited to track use but can be more expensive.

Looking forward to finding out if I have made the correct choice soon.

interesting to see difference in setup of just three cars. Mel do you find you scrub the inside inner most 1" of your front tyres or is tyre wear even across the tyre ?

Hi Laurence!

" Re tyres. Yes I have heard thisl. But front asymetricos no longer available in RS sizes. "

Correct ! Not available in 205.

" I know there are still a few languishing on a few tyre suppliers shelves but my supplier could not find any. And think how old these last ones must be!"

If they are over five years old, forget it.

Corsa' s are the new equivalent of the old P0C, (of which I have two spare 205 section tyres free to a good home!!), so think Michelin Cup tyre and Dunlop R series for similar tyres.

" Mel do you find you scrub the inside inner most 1" of your front tyres or is tyre wear even across the tyre ? "

Very much the latter. When I bought the car it was running -3 front, -4 rear, for slicks.
