You may actually be adding some grip by running less camber in the rear for Drifto.

If you actually look at accelorometer data aquisition you can see the side loads falling off rapidly after initiation to a steady ~.33 G's on most cars (of course depending on the track, banking, surface).

It's still always best to start with a good baseline and adjust per your pyro measurements and tirewear.

 

I run
Front
Camber -2.9/-2.9
Caster 6.3/6.2 ( love those offset bushings)
Toe -0.17 degrees ( that should be a little more than 1/8 total toe out)
Rear
Camber -2.2/-2.2
Toe 0.06 (slightly less than a 16th toe in)
Thrust angle -0.04

 

does the wife not get to run on the stickies?

 

(edit) I was going to say "Boy, that's a pretty old picture" but then I noticed the cut fenders. Where's the Home Depot lip?

 

That's my 15 1/2 year old daughter on her first ever autocross run. So anything that might break off was removed. I am "saving" the 275s for my swing through SoCal in a couple of weeks. She did great right up until the finish where the words "full throttle" may have slipped past my lips, causing her to spin through the finish. I thought it looked kind of like a drift picture, but you guys are on to me.
