    Note: These rotors were pushed to the limit on a fully loaded (about 300 lbs over stock weight) 2010 Camaro doing Texas Mile runs using titanium heat shields, Motul RBF600 fluid, and stock 4 piston SS calipers with braided lines. They worked fantastic for years using Hawk HPS pads doing everything possible except mile runs. These were from the 1st Camaro5.com group buy in 2009 (actually the 2nd set of rings - spares..... 3rd set from another low miles Lingenfelter Camaro on the car now). These are 355 x 30mm and the replacements available are now thicker 355 x 32mm. I've been super happy with the rotors... mile runs and aggressive brake pad combo is what put it over the edge I'm sure.


    THE QUESTION IS: Does anyone know if the combination of changing from my original 30mm thick rotors with the open slot design, over to the latest 32mm thick BUT with closed slots will stop the cracking?

    These only cracked from a Mile run stopping at 201.7 MPH using the much more aggressive Hawk Street Race compound which works at temps 100-1200 degrees ( I should be hitting about 210 mph in Oct 2019 since 2018 the nitrous was kicking off at 199 mph due to a programing error & hit over 200 in Colorado at high elevation a couple months earlier)

    Any suggestions on pad recommendations would be appreciated. The pads rainbow the rotors on mile runs only and I leave the pads on about a week or 2 after the event to remove the rainbow (kinda resurfaces them), then swap back over to my Hawk HPS pads.

      Any ideas? An obvious fix is upgrade to larger rotors & 6 piston calipers, but I also run 17" weld racing skinnies up front for 1/4 mile stuff.

      If the newer 32mm wide rotor rings and simply changing to closed slots would make enough difference I would try that and/or pad change reccomendation for a cold start mile run.

        Thanks for the information I was emailed and discussions. Good to know that the hole location is a little different than my 2010 purchases. I'm looking into stepping up to the ZL1 6 piston front calipers and 2-piece Racing Brake rotors that have the matching offset for the ZL1/CTSV V2 to keep up with speeds I'm stopping at for the Texas Mile runs. Looks like the 2-piece for the ZL1 has 15% more mass due to the 370 x 35mm rotors vs my 355 x 32 mm... that combined with a larger brake pad area should definitely help with heat dissipation and stopping distance. The Cobalt XR1 pads just for the mile runs sounds like a good combination.... pricey, but going fast correctly is never cheap LOL. Now I just need to change my 1/4 mile front skinnies from 17" to 18" to fit. Thanks again! Happy Racing Brake customer.... should hit 210 MPH this year with a 215 MHP tech limit (only a 6-point roll cage vs full halo needed for the Texas Mile "unlimited" car Tech).

        Note: I've never had any cracking from anything up to the hot lapping at High Plains Racing road course... mile runs are a whole different monster! In 2010 me and another supercharged Camaro did High Plains Raceway and his rotors turned blue and were over 600 degrees..... meanwhile my Racing Brake 2-piece rotors kept a full 200 degrees cooler and no warping like his.

          Also.... I messed up and posted the rear rotors by mistake (hence the 26mm min thickness). Bigger brakes and sticking with 2-piece should be the answer for me.
