I'm looking at buying a 135 or 335, but I'm worried about this overheating oil problem, I'm going to get a 6 spd, and only look for one with sport package so I have the oil cooler.

What is the definitive answer to keep these engines cool?

Monacool engine mix/Stage 2 Oil cooler

Is that it? I want to lap for a session with out having to pull over ever 3-4 laps or loosing power. If this is the case, I may just opt to buy a e90 M3, instead but would rather save the money if I can!
I am sure someone can better answer, but from what I can remember, the only way to get good use is performance package (mostly for oil cooler), moocool, Manual tranny, non-blistering ambient temps, and possibly hacking up/modifying air duct to the cooler with a bigger one. Oh, i forgot probably the most important part, proper cycle of warm up and cool down laps. Depending on AT's, idk if you'll do a 20 minute session with 18/20 laps driving at 10/10 with AT's that arent cold. Due to these issues and the lack of a performance diff I find it less desireable to take my 335 to a HPDE.

Because of all this I am seriously considering the M1. If you can handle the smaller coupe (not needing a bigger 4 door) the way I look at it is it has all of the performance advantages of the M3 (coolers, a real diff unlike the 335, suspension etc) with a lighter curb weight and possibly higher performance drive train. I see more tuneability, potential HP, and affordability out of a 1M than an M3.

what i really want to see is what options the 1M has in regards to procede, meth, etc. I havent even looked into it yet so please excuse my lack of knowledge

just my .02
