I've gone with the Dinan camber plates and spring set, 18x10" APEX ARC-8 wheels, Dunlop Direzza Star Spec 275/35/18 tires in a square set up. I mainly do autocross, but if I were going to do tracks, then I'd get some StopTec brakes or equivalent BBK.
I've done some other things, but camber plates are key, along with good tires. Depending on your track(s) and your driving style, brakes may or may not be an issue. Have fun. Dave

dumb question about camber plates. Do you set the camber for track days, then put it back for daily driving? how difficult is that?
I like the dinan option, cause my m3 is a cpo and has a 6 year warranty. |

I run 275/35-18s square and love the ability to brake deeper into the corners. Dave

I'm running at TWS with stock rotors, Motul, and PFC 06 pads with no issues or fading.

one option no one mentioned that I am seriously considering is just purchasing a miata for track days. seriously considering this, with the eventual goal of slamming in an ls1 into it.
I love my m3, and do want to take it on the track, but I think I want to track more often then I want to track with the m3. That make any sense? |

I autocross my own M3 and experience very little extra wear and tear, then I go to Skip Barber or BMW for their track schools to drive their cars and not worry about maintenance. Dave

I've got the APEX 18x10" 275/35-18 square setup on my dual purpose 2009 M3 6MT and feel like it's a great improvement in handling over the stock 19" set up. However, YMMV depending on how you turn in. I trail-brake, so having the extra meat up front is a big plus on turn in. If you complete your braking before turn-in, which many do and that's what most beginners are taught, then the turn-in may not feel as crisp and responsive. Steady-state, bigger is always better, but you have to get into the curve first.
Also, I run with DSC off for competition. When I occasionally drive aggresively on the street, I feel the DSC getting confused and grabbing some inside rear brake at the wrong times. It's not enough to upset the car, but it IS annoying and might lead to premature brake wear on the track, if you leave DSC on. In normal DD I don't notice it. Dave

if I go the track wheel route thats what I would like to get. (apex square setup), but the wife has said that im spending too much money racing
also, I dont have NAV on my m3, so I dont have mdm mode. So its dsc on, or dsc off. I pretty much always drive with dsc off, except for when its raining. |

Yes, whenever the DSC is on. I guess the computer is expecting slightly bigger tires on back and thinks there's something wrong a little too soon. My car has the old MDM, a ZCP may have slightly different settings that negate this problem.

OP, as for the tires, AD08 is probably better track tires, but for DD and occassional HPDE duties, I went with PSS. Almost as good as AD08 on the track, but much more quieter & smoother on the road. Also, had alignment done (negative camber, toe adjustment, etc) as much as it can be done without going w/ camber plates. Seem alright for what I want to get out of HPDE's.

I've got an autocross coming up August 13th. I'll run a practice lap with the DSC on and drive a little under 100% to confirm the behaviour. I'll explore the edges and report what happens. I KNOW that I felt this on the steet, but an AX course will be a better place to explore the edges. Dave

depends on what your budget is.
1. start off by getting the michelin pilot super sports. imo tires are the most important. for those people out there that i see running crappy tires on the M3 or any M car for that matter shame on you. 2. for brakes if you're willing to spend go with the best and get brembos. 3. for a power mod i'd go with a primary cat delete + tune.

for the track, AD08s are better, but PSS are still great you can do brake line fluid pads in you don't want to go all out with a BBK
