Wow thank you. That link really helped. I agree with you on the proactive maintenance. I know I have to upgrade the brakes considering I almost completely roasted them. Figured I go stoptech in the front. I am trying to keep it simple. I love how it handles stock because in reality I know I'll only spend about 1 or 2% driving on the track so I'm not going to go out and get a whole new suspension on anything. My goal is just to do a few tweaks so I can put all the power to the ground. What I was thinking is to add a rear sway bar (already have the front) and possibly get camber plates so I can get the most out of the tires. I would've liked to add front and rear anti roll bars but evidentally dinan doesn't recommend it because my front and rear tires are more then 20mm in width. Of course I'm also going change fluids and adjust tire temps when I get there. I don't want to add power because I feel it has enough. I also would like to avoid getting a set of track tires because I don't want to have to worry about storing them and bringing them to and from the track. What do you think?
A rear bar will help the rear rotate easier, but it will not add more traction to the front per se. In high speed corners, the rotation is helpful, but in low speed corners you won't see much advantage. Camber plates would probably do more than a rear bar. Reducing rear pressure a little will lessen grip slightly in the rear, so you have more of your grip in the front. But remove too much air, and you will feel the tires rolling over. BMW recommends a 4 psi spread on stock tires (rears higher/front), so try a 2 psi spread (rears higher than front), and if that works, go another 2 psi.
I don't think the wider tires really upsets the handling, at least I noticed very little tramlining with the wider fronts. But add camber plates, better brakes and brake cooling and see how you like the changes.
