Took AMG to the track for the first time 2 weekends ago. VIR with the PCA Carolinas region. 4 20 minute sessions Saturday, 3 30 minute sessions Sunday. Tires were Hankook RS4s, brakes Zimmerman cross drilled & slotted rotors (nobody sells blanks for this car) and CarboTech XP12/10 pads (f/r). Was a bit chilly at VIR that weekend! 23°F Saturday morning, and still only 37°F at 1:30 when I went out for the third time. A little warmer on Sunday thankfully. First time out with this car and with super cold tires, you better believe I eased into things
Car did really really well. There are many places where I know I'm leaving time on the table but am okay with that because a) one of those turns is where I balled up my BRZ and b) the margin for area in some of the places is very small and I don't want to damage this car. Beyond that, I'm not a pro so I know there's probably a lot of time left that I'm not even aware of.
In a nutshell the car is fast, REAL FAST. I was able to go around 12 seconds a lap faster than in my Cayman. Car felt super stable in the climbing esses: on my best laps I entered them at over 130 and left around 110. Lap after lap, the car reached close to 150 on front straight and over 160 on the back straight.
People online seemed to be concerned about engine oil temps getting too high (tracking in the fall was by design to help prevent this) but I never saw higher than 266°F. Likewise the transmission never overheated (another possible issue for 2012+ C63s) though it did appear to jettison some fluid out of the vent hole. Brakes, however...oh boy. I had thought there was some sort of venting for the fronts (I mean it's an AMG) but there are not. As such, hauling 4000 lb down from 150-160 lap after lap did some damage. Measured back in paddock my rotor temps were 800°+ and I started boiling brake fluid while on track both days (fluid was fresh before event). Sunday morning I did another full brake fluid flush with Motul 660, but it still boiled.
Post event consumables condition:
- Tires look great, many events left in them
- The front rotors are shot. Cracks everywhere
- Front brake pads are down to 6mm, rears 9mm. Should be good for another event.
- rubber caliper piston dust shields are pretty rough. 3 per side all cracked. Planning to rebuild them all before next event.
Here's a video of my fastest lap (please disregard the overlay data as it's 1-2 seconds out of sync and most values are off entirely).
I was the only AMG out there and got many compliments from other drivers about the sound of the engine, and for tracking a big sedan like that in general.
