Track Days
I did about 10 track days in my M235i last year. I went through two sets of MPSS tires and I'm on my third set of brake pads. This year I'm going to run on a square wheel and tire setup. First outing this year is set in early May at the Glen.

I am, however, only on my second set of brake pads (switched to Porterfield R4-S pads). Nice thing about living in SoCal is you can do track stuff all year around (except in mid summer -- too hot). Are you bone stock or have you done some track/suspension mods? Last edited by Liquidpaper; 04-14-2015 at 02:46 PM.. |

What tires would you guys recommend?
Looking at these http://www.tirerack.com/tires/TireSe...tpackage=false I'm between the RE-71R, Direzza ZII Star spec and the Ventus RS-3... Didn't hear very good things about the Rivals but not sure if the new ones are better |

Of those, I've used the R-S3s and the Star Specs. I personally like the Star Specs more. But the R-S3s can be found locally. Must go through Tire Rack to get the Star Specs.

If you want a no-compromise tire, Star Specs. They stick like glue and handle heat pretty well.

What's the diff between the regular direzza and the Star spec ? The new RE-71R looks like a copy of the Direzza... Also there is a $70 Visa prepaid card with the RE-71R so about $18 less a tire |

What's the difference? No idea. But tires are consumables, so if you can get the normal Direzza II's for cheap, go for it. They can't be THAT much better.

and $270 on top of that for the TPMS So comparing with the PSS that is what I have used so far on 1 track day... how do they compare with the Direzza II's for those who have used both ? |

Also, the Direzzas are stiffer (stiffer sidewall) and provide better feedback, are stickier, handle heat better (don't get as greasy), and are generally more durable given a proper alignment (don't chunk). Great tires. |

So Direzza's are directional so I can only rotate front-rear.... Also there is no inside or ouside right? so I could eventually have the tires remounted insideout left front to right front and viceversa if LCA is not enough help for camber and the shoulder wears ? What PSI do you run on the Direzza's? |

Only one trackday with mine so far, but plan to do more soon enough!
That said, I managed around 30 laps @ interlagos in this session, which isn't so bad! The thing about interlagos is that the right side tyres wear out faster than the left side ones. Since I was running on stock staggered PSS, for the next time I'm planning to use a square setup with slicks! It was extremely hot that day (around 35ºC), and I only drove on the morning session. Still, I was a little disappointed that around noon the car began to overheat. It didn't go into limp mode per se, or throw any lights, but started to top out at 200kph and shift slower... Extremely annoying, specially since I was battling against a new audi S3 on semi-slicks! Not sure what to do to prevent this next time around! Last edited by rpagianotto; 04-14-2015 at 10:10 PM.. |

I think that's exactly it, my car doesn't have the auxiliary radiator or the hot weather package! To me, it's stupid that BMW won't bring cars with them to Brazil, of all places!
Unfortunately during the trackday I wasn't able to access the secret menu to check oil and coolant temp, but like I said, the car didn't actually go into limp mode! Just something to look out for! |

I'm on the e90m3 section but browse all the track threads. They should be non-model specific!
Strange on m3post everyone runs RS3 and I thought the star spec was more of an autocross tire, or maybe it's because of the sizing options.

Also don't waste money on tpms on a track set! You should be monitoring tires pressure anyways.

Also it's nice to be able to check tire pressure and temp in real time while on the track so tpms is actually quite useful |
