Suspension Alignment for Track

[thebishman]

I was in a workshop today getting a wheel alignment for some track work next week and the car was up on the hoist.

I was quite surprised to see some of the aerodynamic differences between the V10 compared to my old V8.

There was quite a bit of fine detail work directing airflow under the V10 body that you don't see on the V8.

So without asking a silly question is the front splitter more suited for the V8 than a V10

Aesthetically its fair to say its compelling.

Gazza,
Can you share the post-alignment settings you chose for the track?

Hi Bish..

This is what I settled on with the adjustments available.

Front

Camber LEFT - 1.8 / Right -1.6 (both maxed)

Toe - 0

Caster - left/right + 7.2


Rear

Camber - Left - 1.2 / Right - 1.1

Toe in - -0.5


Car felt much better on my little twisty mountain road on the way home.

Brilliant. Thanks for the info. Now am awaiting your post-track thoughts.

Your numbers are very similar to what, after some experiment, I ended up with on my V8:
Front
Camber approx -1.4 (both maxed)
Toe +0.3 (stock)
Caster ?? (stock)


Rear
Camber -1.15
Toe- +0.3 (stock)

I still need more negative camber in front, very nice that you can get -1.6 or more. I'd like to add shims so as to get maybe -1.8 or -2.0.

I tried more negative camber (-1.5) in the rear, but got wheel spin out of the corners and corded the insides. Guessed at the -1.15 and rear tire wear seems very even now.

Car felt better the faster I went..

I was unsure about zero toe at the front but I had strong straight line stability.

Running the same Cup tyres as my previous R8..I had less roll under(ploughing) at the front as has been the case previously.

All in all a good set up

In a friend's P997 he over did the negative camber. His front driveshaft diff. broke. It would be nice if we had the numbers from a track setup factory team R8.

With your MPSC tyres are you running the 305s in the rear and 245 in the front?

Track cold/hot psi?

What brake pads?

TIA, Bish

With your MPSC tyres are you running the 305s in the rear and 245 in the front? -Yes on both

Track cold/hot psi? - 36psi hot - all round


What brake pads?- stock held up well,but will upgrade pads for next time.

I am trying to copy your parameters for the aligment, the guy at the dealer is asking me if these numbers are in mm or degrees? help appreciated
thanks
