No undue rotor wear. I got 30k out of the oem rotors before they wore to min specs. You'll probably have to scrap the rotors due to cracking before you wear them down to min thickness. |

When you guys change out your oil, do you just use an extractor and keep the oil filter (changing out the oil filter at the 15K intervals)?

I changed when my engine oil temp overheated or about 2-3 track days depend on how hot the oil temp gets. Always change the oil with oil filter together.

What cooling plates did you use? Any pics?

I don't know. I believe it's custom made. I'll take some pic when I jack up the car next time.
For the brake ducting, it worked perfectly. If the inconsistent braking gets solved by brake ducting system, then I have 4 guess for the root of cause: 1 my AP bbk can't handle heat; 2 mintex brake pads can't handle heat; 3 BMW didn't build any cooling for the brake; 4 the issue Martin has addressed. |

If ABS is not working properly in certain conditions (which could be an issue with the modified bias of an aftermarket system), you might not always feel something significantly different in pedal feel, but can experience significant differences in stopping power/distance. One can usually observe what I mean when trying to threshold brake at a bumpy braking zone vs. a smooth one on the same day at the same track. (Of course, braking on a bumpy section complicates traction as well, which also factors into ABS operation). Anyway, I am speculating and there are many potential causes that might explain the inconsistency.

I have 40+ track days and 43,000 miles and so far so good. Also my AP brake kit is flawless other than occasional brake groan on the street since I started using Pagid yellows front and rear.

I have a good 40 days at the track in my E92, all at VIR. Stock everything except for PF Race pads, SS brake lines, Apex Rims with BFG R1 275X35X18 compounds sq setup. Brake fluid, oil, filter change at the beginning of the season, checked prior to each event. Have used no oil. Note, my car is not run all that hard each session, however, it does see some agressive driving during every event. I too am struggling with what to do going down the road, seats, restraint, roll bar, suspension, brakes. I think that I will leave the status quo in tact.

I've beat on my E90 for 6 days over the last month and a half. Not even a year old and its at 17k miles! I'm on my second set of PF01s...the car eats brakes!

Had my first track day last Saturday. Car was pretty easy to drive considering how big and heavy it is... This was not a planned track day for this car. A broken car forced a last second switch to this car. 5k miles on the car. My experience level is long and sordid (raced for 10 years, instructor, etc., etc.), though I have no remarkable skills.
![]() Brakes became an issue when I decided to be more aggressive in two pretty heavy braking zones (Spring Mountain Motorsports Ranch in Pahrump, Nevada -- 3.2 mile configuration). Pedal went squishy and stayed squishy. Pressure bled the brakes the next morning and there were no noticable bubbles. The cheese grater brake rotor holes were full of stock pad material (have others seen this?). Clearly, PF-08's would have been a better pad choice, but I wasn't planning on using this car so it didn't happen (I don't have a set of performance pads for this car...). I had a few drops of power steering fluid on the reservior after the event. No noticable oil consumption per the idiot gauge in the dash. No temp issues, but we had absolutely amazing weather with high temps in the low 70's (unheard of). Great day all around!

Pad "knockback" is a phenomenon that happens with BBKs sometimes. Tapping would push the pads back closer to the rotor and leave you with less pedal travel and a more solid 'feel'. Worth a try to see if it helps or not.

Can anyone comment on how their car has held up to the wear? Do your front bumpers/hoods get blasted with debris?
Also, do you think all the tracking will have a substantially negative impact on resale value? I have 35k miles on my car, no track days, the car looks brand new as I've kept really good care of it. I'd like to get into tracking and use my car. I'm afraid of things getting beat up badly. |

Oh yes, plenty of rock chips on the sides. Not so many on the hood but I have a clear brea on the bumper and front part of the hood up to the bulge.
Without the bra...my car's paint would be looking terrible.

i bought mine used and made the mistake of not getting clear bra anyway even though there were a few chips. now there are tons. the front fascia and hood need a respray at this point due to tracking.
