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.

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.

you can safely run 5mm worth of spacer on the stock lugs. Does that solve the problem sufficiently?
Or I can just again have 2 sets of alignments street and track. I think 5mm spacer will solve the problem but I don't want to run spacers.

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.

As I said I don't want to argue that seen stories not with mustangs but other cars with spacers on local track and it's not pretty one of my friend had a nasty incident just a month ago where on his BMW Z3 all 5 studs were cut because of the spacer with over 150 km/h was magic that something serious didn't happen. My local track have a lot of curbs that you literally have to jump over in order to be fast this is not good for spacers. Which is why I opted for ET-26 front wheels and I'm happy. Also as noted I got rubbing from the street set not from the track one. Because the camber is too much.

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?
