Bump steer kit will fix it right up. You have to get the suspension geometry back correctly after doing springs. As the front tie ends are fighting their self. Done this to mine and was night and day difference. Must do mod with lowering springs.

Pressure is 43 hot

Yes more spring is needed.

43 hot? What are you starting at cold?

Thanks Sho!!!

I don't have my notes in front of me but around 36.

I was deliberately overdriving.

So the plan is to drop the air pressure. Run some laps then add the spring rubbers and run some more. I don't want to have 2 alignment settings so will keep the -2.5 front. This works well for me on the street with my street tires.

If after the above I might add sways.

Really I started this thread to have you guys tell me I needed sways. Want to justify the new toys.

Anyway I think you all have helped my setup. Thanks.

That's often my error as well. It's easy to over-charge a corner and then you just have to wait *forever* before you can get to gas. It's super frustrating.

Ugh it’s so hard to slow down enough for that one. Just feels like I’m stopping on track.

Just before the sign "2' and trail brake till apex

FYI...
I run 28mm Hub centric spacers..on track..and on street. since 17k miles.
And you know ..I push hard on track lol
Hub centric ( NO THE ONE WITH EXTRA BOLTS) are safe and proven muyltiple time to the race community.

then don't take your street wheels to the track. Changing camber is just dumb.

your fear of thru-bolt spacers is irrational and without cause. Your buddy clearly did not torque things properly. Wheel lug bolts are NOT designed to take the sheer forces, the clamping-induced friction is. Any spacers you use should not be painted for this reason. Anodized is fine.

I always trail braked into that one. My problem was oversteer on exit. Especially terrifying because there was astro turf on runout there way back when.

That sounds like an excuse to get a new street set with a more aggressive offset. AmIRight?
