I would not recommend ps2 tires for lapping. They are good street tires but they are not track tires. I almost destroyed my brand new ps2 tires after 1 track event at thunderbolt NJ. And i was in 135i wich is lighter than e9x m3. My front tires were rolling over and riding on the sidewalls when got overheated. That is dangerous and could lead to tire failure. Sidewalls of this tires are not reinforced as much as other high performance street tires. Thats the reason they are a lot lighter than dunlop star specs for example. Iam not trying to scare you. Just my 2 cents

It all depends on how many times a year you will track your car. If its just 1 or 2, than i would stick to what you have. As a novice driver i think you will be ok. But if you track more than 3 times, a separate set of rims /tires is a must in my opinion.

The PS2s do not hold up well on the track compared to other brands when you get more competent and faster (I am comparing with another brand, which I won't quote to avoid a brand war). If you can find an M3 in a more experienced group, they will be able to help you modulating tire pressure and ensuring even wear through the day (hence everyone telling you to get a tire pressure gauge). Don't be afraid to ask for help during the day - everyone who is there has been exactly where you are as a novice, knows how you feel and is willing to help...especially a damsel in distress! The tires will be grainy/scrubbed when you are done, but they will still be in good shape. Michelins are expensive because of their compound composition quality (and their brand!) |

As for becoming an expensive hobby, if you become addicted to it like many of us, well, it can be. You'll go through tires and brake pads regularly. I change the oil after 3-4 track days, which is also $120 per change. So it all adds up, but you have to pay to play. Actually, paying for the track time is the cheapest part. Do you have PS2's now? Like others have said, they're not very good for the track. They get greasy after a couple of laps, and they're expensive. I'm currently using Bridgestone RE-11s, and I've been really happy with their performance so far. I'll probably try Yokohama AD08s next.

Keep an eye on your sidewalls and increase the pressures a few pounds if you are getting wear past the triangles on the sidewall. You'll be fine on the PS2s.

I've found that PS2s do not handle heavy braking very well and wear out fast on a heavy car. I wore out my fronts in 4 tracks days, and the rears were fine (not talking about outside edge). Sidewalls are a serious issue as long as hot pressure is maintained ~40psi IMO. As Skierman said, these are all nonissues for a first track day...
EDIT: I meant to write, "Sidewalls are NOT a serious issue as long as hot pressure is maintained ~40psi IMO."

Do you have the Skip Barber book "Going Faster"? (http://www.amazon.com/Going-Faster-M...9378056&sr=1-1)This is a great place to start reading up, and it helped me make sense of what the instructor was trying to get me to do (2nd time out, I wish I had read it before the first time). It is also something to read the night before at 2am if you are too excited to sleep! The Ross Bentley "Speed Secrets books (http://www.amazon.com/Speed-Secrets-...9378101&sr=1-1) is good too. Again, you'll get various opinions...this is mine |

I like to keep the rev's in the 5000 to 8,000 range. The more hard core guys will go all the way to 8,400

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."

Ps2's are not only VERY expensive but NOT worth replacing when you can get WAY better tires for less. They melt on the track when pushed and I found got slippery when overheated. I would recommend a good set of street/track tires like the Star Specs mentionned or, AD08's, RE11's,NT05's etc...Plus they will LAST you much longer for dual track/street use.

I havent read the other replied, but my suggestions:
Before you go: remove everything from your car (mats/glovebox stuff). Learn the track via youtube so you know which way to turn! Go to websites talking about apexing and heel-toe and try and learn driving basics. Learn the flags for your club (they can differ from club to club). Bring: torque wrench, snacks/food (I like PB&J and chips), lawn chair, LOTS of water (stay hydrated, force fluids, pee before going on track ), decent tire pressure gauge (borrow a IR temp gauge if you can), painters tape (for your #'s), up to date helmet, camera, and shoes which have thin soles and fit snug. Do: park near a shady spot, meet others (especially ones with the same car), have a good time, LISTEN to your instructor (You dont know more than him/her), drive within your comfort level (7/10ths is just as much fun as 10/10ths IMO), WATCH your rear view mirrors for cars coming up (wave them by early on the straight), watch the corner workers. Dont use your ebrake when in the pits, just leave it in gear on a flat area. Dont worry about upgrading your car for the first few events. The tires and brakes and fluids are all fine for a first-timer. You're going to love it! Post pics later!
