Whatcha' all running?
Mine is a 4 cyl, 225/50/15 Toyo RR's on all four corners. Front suspension from an '85 911, rear has coilovers and reinforced trailing arms with diagonal braces. Thx! |

I'm close to 1.5 degrees negative camber on all 4 corners to get good even tire temperatures. Had earlier been running more negative but for road racing this is better--I think the autocross gang uses more negative. That said, I'm in a /6 with 215rwhp weighing 1950 pounds without me in it and on bias ply Hoosiers.
I ran Toyo RR's for years and loved them--225 all around--great tires, start at about 29psi, finish 30 minute session about 33-34psi. Get a probe type pyrometer, failing that get a good sensitive feel across the tread on all four corners to set your camber to get the temps even. Toe is just a bit of toe in front and rear, say 1/8 inch max. Hard braking prior to turn-in tends to spread the fronts in the direction of toe out....ymmv... |
