M2 madness

[M3M3]

wow, some golden oldies Jim!

[M3M3]

Yikes....putting it away away for the season turned into over a year and a half.   Work,  retiring and beemers got in the way.  Gotta teach at a BMW track school this weekend,  so time to get the M2 out of hibernation!

Well I was wondering!

 

[M3M3]

retired two weeks ago and starting to catch up on all the hobbies!
 

put about 700 miles on JGerock's tii attending OFest.  So nice to drive a 2002 on the street.  His car is the perfect combo of sporty and comfortable.

 

now it is in temp storage completing the BMW sweep of my shop.  roundels only!

 

got the M2 up on the lift for nose to tail examination.

 

new front rotors installed with PF01 brake pads.  using a "floating" rotor this time as a last attempt to mitigate the horrible pad knockback from the larger brake rotors.

 

rear just got PF01 pads.  got to use my caliper modification to drive the pistons back in to fit the pads.

 

then did full brake flush.  yikes...there was still some blue in the color from old ATE Super Blue brake flluid.  last used that a couple years ago.

 

dropped the suspension about 3/4in front and rear and dialed 3.5deg camber into the front.

 

also realized the trailer needed some maint.  tires had a 2009 date code even though they looked good.  two of the four new trailer tires visible by door of garage in third pic.

 

weather not looking good for the event though.  chance of showers on sat and a wash out forecast for sunday....m2 may not get much use. argh!

Nice to see your car again!  I'm interested in the floating rotor mod.  Is this something from Lee, or one of your own devices?

[M3M3]

Stock part from Coleman Racing.  Rotor bolts go through bobbins that can slide slightly in channels on the rotor.

Hope we will get to see some track footage.  I have missed it.

[M3M3]

ok...track footage attached...

 

two track weekends have past.  have been chasing two issues...front brake knockback and fueling.

 

front brakes - installed floating rotors. this fixed the knockback issue, but introduced serious brake vibration. only happens on light to medium brake application, so i just only brake HARD...:-)

 

fueling. first issue last year was over rich condition.  problem was found to be a pinched fuel return hose.  fixed over winter.

new issue this season was an over lean condition after about 10-15min on track.  took me a bit to figure out that it was the new AIRTEX lift pump in the tank.  cheap junk.  replaced with my old bosch pump.  works fine.

 

last weekend was instructing on the Summit Point Shennendoah Circuit.  two miles, twenty turns.  here are a few laps.

Wow that track will keep your hands and feet busy.  Love the rear caliper mod.

The Shenandoah circuit is perfect for a 2002.  

[M3M3]

i got SQUATCHED!

 

hood done.  took almost a whole can of 3M 90 spray glue.  gotta order another one for the trunk pads.

 

 

[Colin]

Does it help much?

[M3M3]

will find out when i get to drive it....although there are too many variables to isolate just the pads.   it is still on the lift.  finishing up experiment of changing from track car to street(ish) car.

 

front springs 7x450 to 8x250

rear springs 7x500 to 8x400

brake pads (and rotors) from PF-01 to willwood street compound

ride height up an inch

front camber from 3.8 to 2.2

rear camber 2.5 to 1.5

front toe from 1/16 out to 0

rear sway bar to full soft

muffler from straight through to small magnaflow

both seats raised 1in

steering wheel swapped to sparco with 3in hub extender

CF hood replace with stock hood

spare tire added

wheels and tires swapped from Kook 214 r-comps to s.drives that really should be trashed due to age.

 

might get to drive it tomorrow!
