I got another reply on mustang evolution from another autoxer and he gave some very good tips. He mimiced some of your advice, so I think I'm on the right track. As for your tire pressures, I'm surprised you ran that low. I was at 38 for the bimmer, but that was a more narrow tire, so this may be the trick. What width do you run?
As for the hawk + pads, not a big fan of those, no modulation. They are either on or off. I had a set of BHP CR6 pads on the 328 and like those a lot, but I think BHP is now of biz, so need to find something else.
Next year will be a search for shocks/struts and front sway. I see you said your changing out your catback. You doing that to remove weight or is there any performance gain? You have any dyno sheets to back your catback install?
thanks....

Tires pressures will change pending on the tire you run, so it isn't an exact science ya know. I run a 275/40R17. My brother has a Spec E30 that he runs in DSP, his tire pressures were 30-31 psi on a 205/50R15 hankook Z211. Not really an autocross tire more of a track tire, like my RA-1s and your Victoracers but you get the point. It is all different depending on the tires and sizes. We will both be on better autocross tires this season and it will take an event or two to find the optimal psi out of the tires we'll be running.
As far as the exhaust, I have heard the system I am getting is lighter then the factory system but I am guessing it is marginal. Maybe just a few pounds, not enough to effect anything I don't think. I just like the sound a whole lot better
An alignment will help also. I have the same camber bolt kit in my car that Kirk mentioned. Actually according to the rules, it is the only stock class "legal" camber kit you can use. But if you aren't running against Strano at nationals, I do not think you'll have any issues locally.
You can grind out the bottom hole of the strut to help gain some static camber, you won't want to get more then 2.0 neg camber. Again for the rules, if you have more people will wonder what else you did that isn't stock class legal. If you pull out the strut and look at the holes there are kind of like parenthesis around the holes, looks like (o). You can file out those holes to those lines, I did it with a hand file on my Koni's. Once you do take it for an alignment to see what you can get. I run -2.0 camber with the toe set to zero. I do not have any tire wear issues. Caster is at 7 degrees from the factory which is plenty.
