Might help if you ditch the rear bar.

Also, 225s won't fit worth a darn on those +20 wheels you've got. Go with a x8 +32 or x9 +36.

225s will be better, R comps better still. But with that amount of torque you'll still be able to rotate the car at will. Probably just need to work on driving smoother.

Yeah, I loved my wheels until I read more about proper offset and now I hate them haha. I didnt think I wanted R comps since I daily the car and drive to the course but it seems the next step is to get a dedicated track setup. Either that or I sell my current setup to cut some cost on a permanent 15x9 225 street/autox setup. Decisions decisions....

Thanks for the input

My car is useless at autox. Last week I drove a tight/short course and did "okay" but I drove my buddies NB with stock VVT engine, torsen, 15x9 w/ rs3's, and 500/350 springs and stock sways & managed to beat my own time.

I am on 15x9 with 225 rivals...but the tires aren't the issue

Issue 1) 700/400 xida's. Fantastic on the track,WAY too stiff for autox
Issue 2) Slightly larger than stock rear sway
Issue 3) ... a big one... 11.75 BBK with DTC-60's are on/off when cold. I struggle to find the threshold without locking up.

Long story short going to 15x9 is a very good call, but be aware there could be other changes that would greatly improve your car at autox. Street vs Autox vs Track are 3 very different car setups.

My friend is doing great on 700/400 konis. I am hoping the xidas will work out since it is a huge investment haha. Emilio recommended the 700/400 for strictly autox. I wont be going BBK for a while so im good there. I may try removing my rear bar also to see if that helps.

Big courses or small tight shit? Dampening settings make a huge difference too. I tend to play with them quite a bit depending on the course.

umm about 45-50 secs with a few slaloms, a sweeper then 1 or 2 extras like a chicago box or wide slalom. rarely hairpins though
