Roen's CASC-ON 2018 OTA GT2 Build
 

I took the Evo out on a shakedown run this past weekend to test out the Dodson Heated Sump and the AMS SST Cooler.

Trans held up to heat well first session, but the brakes got very long and soft. Had to pull off around the end of the session, but should've just coasted around to cool the brakes more. Brake temps were at 800F in the pits. Brembos went from burgundy to black. Nicely cooked. Brakes fully to the floor in the pits.

In the second session, I got brake pressure back, and set a new personal fastest lap all time at this circuit, albeit with a trans that was having shifting issues and a long brake pedal. Clutches seem like they're on their way out, but they have been for a very long time now.

Setup this time: Front: PF1001.11 Z-Rated, Rear: DS2500, Stoptech 660, Stock Cat, Nitron R1 650/727, RE-71R 275/35/18, -2.5 F / -2.0 R, 0 Toe, +1 degree of Caster to Stock, New Spark Plugs!
Setup last time: Front: ST43, Rear: XT910, RS683, UR Mini-Muffler Test Pipe (No Tune), Stock Suspension, RS3 V1 265/35/18, -2.0 F / 1.5 R, 0 Toe, Stock Caster

I'm fairly comfortable with where the car is now, but need more seat time with the coilovers. These coilovers aren't the best winter friendly coilovers and are now pretty much non-adjustable in the front. It's fine though, the car didn't feel overly uncontrolled on the rebound side, nor did it jack down much due to too much rebound. Also, due to the nature of the tracks here, I may soften the spring rates to 10/11 with the appropriate re-valving on the next shock rebuild. The braking performance is terrible compared to previous, and that's mainly due to driver confidence with a long brake pedal on overheated street pads.
