So while I'm waiting to clean my new calipers, I figured I'd report my results. Last track day at Laguna was on OEM everything and DTC 70 pads front and rear. I cooked everything but the pads did work well so I bought the corvette brembo 6 piston calipers and set up the car for my first day at thermal (north+south circuit). Setup was oem rotor, dtc 70 pads and new front calipers. Running RBF 660 on prior setup and this setup. The kit allows me to run a larger rotor, but I wanted to control the upgrades to see how each worked.
Results: night and day difference. Was out-braking my buddy in his C63 black series all day and had no issue of over heating or fade. I was seriously surprised, to be honest. Also, my rotors are in much better shape after this day than my last track day. Looking forward to upgrading to a better, larger rotor for next round but very happy with the upgrade so far.

I do left foot breaking even in my manual car on certain sectors so transitions are immediate. I've done plenty of practice on the street where you slam on the brakes in the beginning.
One time I also want paying attention and my left foot was on top of the brake pedal and I went to clutch in. Lol. Yikes. On the track it's easier since I know which sections I'm using it in.

Interestingly 204 Black Series have the same caliper, no idea what disc. What pad/tyre was he on? Might be that extra weight.

I obviously need to do some testing - I'm curious on the shorter races like in NASA where they are 20 to 25 min long where they all would rank when it is hot outside. |

Anyone here running a clutch LSD, specifically OS Giken? Does it make a squeak (pop?) sound like in the video below? Mine does it when I get on or off the throttle.
Not sure if it's normal LSD sound, or if something is loose in the rear axel/subframe causing the noise. I also have Powerflex Purple diff bushes. |

I'm re-thinking my April outing. Have been planning on Hallett with the SCCA Hoosier tour - finish both races and I should be eligible for the nationals so we can keep that option open for later. But as of now no one is signed up in T1...
NASA is at Eagle's Canyon that same weekend... WRL is at Mid Ohio... Haven't been to any of those and all 3 sound awesome. Mid Ohio appeals the most to me but I'm basing that just on videos. |

I'm going to make a more detailed post and upload some better pictures in one of the rod bearing threads, but I couldn't wait to share! Cylinder 1 and 2 bearings were the only ones worn down to the copper after 163k miles. Can't wait to get it back out on track in a few weeks at Road Atlanta!

I know the north Texas “lone star” chapter is really trying to boost racing participation. Race school at MSR in May will hopefully help with that. COTA races in June looks to still be moving forward, and we did Hallett last year so not sure why we wouldn’t do a race weekend there again this year. Dates for the hpde are currently set for September.
