After this weekend (autox school on saturday, autox event on sunday) my Hankook Ventus RS2s are heavily worn on the outside edge both left and right. By heavily worn I mean, the wear triangles are gone, the voids on the edge of the tire are gone (compared to their counterpart on the inside edge.) Not enough pressure? Alignment need tweaking? The pressures I was running were 38 in front and 50 in the rear. Do I need to dial in more camber up front?

The suspension related stuff on the car so far: Helix/RDR camber plates, H-Sport lower control arms, R-Speed 22mm rear sway on medium setting, stock springs/shocks (MCS). Current camber settings are -1.8 in the front and -2 in the rear, need to check the toe settings, but don't have my alignment sheet handy. I'm guessing I should've been running more air up front.

The car was run a lot this weekend, the school was ~18 runs around the small training courses (rectangle, slaloms, decreasing radius turn), then 4 runs on the full course. Sunday it was run in EM (3 runs), and STX with two drivers for a total of 9 runs.

Any ideas or suggestions?

these 205/50/15?? im running close to that with the hankooks and wear is at top of trangle .. with no camber plates. have been through 6 autox and 1 school.. so i would check toe in if both side seem even. For down there we see to get mainly Right hand sweeper so mine are a bit worn more on that side.

 

205/50/16 is the size of the tires, the courses for the school were run both ways, the full course on Saturday would've been a bit more biased to left turns, the course on Sunday was the reverse with a few modifications but more biased to right turns.

The hankook's like more negative camber than most tires and less pressure and your rear camber needs to come down to -1.0. I would suggest -2.5 and 34 psi for the front as a start and don't be afraid to go down on the pressure or use more negative. For dry use the tires really should be shaved, they will be faster and last longer. You may want to get two new shaved ones and just put them on the front, when you autocross.
