:waves: everyone,
I'd like to get ya'lls thoughts on my brake bias behavior changes after going with a CorteX track setup. I'm pretty happy with the CorteX stuff and the setup done by FlimFlam Speed in Richmond but I am now wondering about my brake behavior. The main reason is now it's opposite from what the brakes did before the mods. It might be me which is what I am really trying to determine, I don't know what I don't know. I (try to) do the driving. ;-)
For the first three years I tracked my GT500, Van helped me with beginners type stuff. Brakes, fluid, general questions stuff to be "safe" for getting into tracking my car. I was running Raybestos ST-43 pads at all 4 corners with stock Goodyear tires (and a stock car). I ran the stock rotors (thanks Steve for all the stock parts). I ran the Brembo LCF fluid. Did full bleeds after every weekend. Replaced the front rotors after 4 days of track time (e.g. about 2 hrs / day). Around the third year, Van suggested I know what my brake temps were. Not having any issues, just to know what they were. I ran the Alcon stickers on the fronts and consistently saw 420 (ish) deg F. I never put stickers on the rears because I usually got a whole season (or most of the season) out of a single set of rear pads and rotors. I rebuilt my calipers or bought new calipers from Steve in the off seasons.
For this year, I changed up stuff a lot. I've got the CorteX track version of their coil over setup, watts link, torque arm, LCAs and sway bar links. I am running FRPP Boss 302 front LCA with the delrins and MM bumpsteer kit. I also run the Eibach 36mm 3 position front and a stock early GT 18mm rear. I have ran both the FRPP Boss S/R ABS module and the original OEM ABS module. I am running Toyo R888R 305/30/19 at all 4 corners. My front bake temps are around 290 to 300 deg F and my rear brake temps are 420 deg F. I can tell the rears are now getting used big time compared to pre-CorteX setup.
About the only thing I could think of is the torque arm. The weight transfer / pitch is pretty much not happening like it use to. So my question is can a torque arm setup cause such a drastic change to the brake temps? From everything I've read, 300 deg F for Brembos is "cool" and not in the "normal" range. I haven't noticed pedal feel difference, the car is very different than it's stock form and I am still re-learning the car. Braking is one the areas where I am struggling to re-learn. Or maybe the first question should be are 300 deg F front caliper temps OK?
About the only reason I found (so far) to run the FRPP ABS Boss S/R module was that I have to disable both "modes" of traction control. In the turns, I was triggering the traction control kill (the 3 seconds of no power). The racing ABS module does this automatically on KOEO.
I'd appreciate any help. Thanks.
