sweetm3 180 Report post Posted October 10, 2010 Just arrived home from a day at Hampton Downs. Started of gingerly as you would with the new setup. See: E36 M3 brake upgrades I need some clarity thread for the setup. Slowly started to leave the braking later and later, happy to say I didn’t push it past what the car or I could handle. But still knocked 3.7 seconds off my previous fastest lap time now down to 1.21.1 OK I was taking temperature readings on my rotors, the front were reading 210F and the rears were 420F I would have thought it would be the other way round. I would be interested in any input you guys may have Quote Share this post Link to post Share on other sites
|ncary 0 Report post Posted October 10, 2010 When you are doing the cool down lap (you must be with only 100deg Celsius on the front) the front brake ducts (even just the stock duct holes in the M3 skirt) will be cooling the front rotors while the rears are stuck in the rear wheel with no ventilation.

polley 916 Report post Posted October 10, 2010 whats this degrees F crapI believe it is the imperial measurement of temperature . Quote Share this post Link to post Share on other sites
sweetm3 180 Report post Posted October 10, 2010 (edited) whats this degrees F crapWell I was checking toyo site re R888 operating temperatures before I left for the track, once at the track I changed my Infrared Temperature reader to F and didnt change it back Edited October 10, 2010 by sweetm3 Quote Share this post Link to post Share on other sites
|ncary 0 Report post Posted October 10, 2010 Rears are vented and two piece Ducting is a bendy pipe that directs air to the rear-inside of the rotor to provide ventilation. Even if the rear rotors are vented and 2 piece they still don't have fresh air being pumped in from behind. Head out to a big straight road and do 5 hard stops from 100 to 10kph, then 1 more from 100 to 0kph, then run around and measure the temps, should give proper readings. Then get moving quick before the pads glaze/whatever. Quote Share this post Link to post Share on other sites
