Race/track alignment specs?

[Jriley9922]

I'm running 4 rear wheels with 255s.
Car is being built into an endurance race car...
Coilovers with camber plates and links going in this week...
What alignment are people using for track only with 255 square setup?

Below is my alignment for 2001 Boxster with lowered coilover suspension with stiffer springs (6kg/mm front and 8kg/kg rear).
I do not run square set-up, but 225 front and 255 rear.

This set up is fantastic for example at Nordscleife and Kymiring, but like yesterday I was at almost flat track (Alastaro Circuit) for 4 hours, the car had still some unersteering... would probably still need a bit more camber at front.

What size wheels you have to fit 255's nicely - also ET would be interesting?

Thank you much mate!
I'm running rear 986 wheels on all 4 corners with 255 kuhmo 730s

To answer your question, nothing fancy
Just stock... So I think they are 17x8.5 50offset

Fantastic, thank you! I have been thinking a square set up as one option for next winter tire shopping. I'll look further on to this 50 ET 17" wheels sizes you have.
And I guess, you have not yet seen tire rubbing in to the fenders?
Is your suspension at the stock height?

You could get a second set of your current wheels and run 4 rears in Summer and 4 fronts in Winter, that way you're always square and don't have to buy a loose pair of fronts or rears.

zero toe front 1/16" toe-in rear. as much camber as you can get in the front (-3 with camber plates, -4 with adjustable lower control arms) and about one degree less camber than the front for the rear. i am at -3F -2R but would like to get to -4F -3R once i get wider control arms. upgrade the swaybars and then play with tire pressure and trail braking to balance the car out.

Thanks. Going to try this and see how it works for me.
