Anyone know how much those two weigh? Please list separately. I just measured the Precision Brakes 1pc 12.75x1.25 rotor and it weight approximately 20lbs and the superlite caliper weighs approx 4.5lbs. I'm now thinking if i'm just adding more unsprung weight to the car with these big rotors. I had the option to go with 2pc rotors, but the 1.25 thick 2pc rotors have clearence problems and I was told that the 0.81 tends to warp rather quicly. Didn't want to deal with that as I go to the track quite often.

I have the 18X8.5 Volk TE37 coming (~ 18lbs) as I was hoping to reduce the unsprung weight.

Anyway, if anyone has weighed their stock rotors and calipers please let me know.

Also, if anyone's interested, the stock rims w/. 235 45 ZR17 Nitto 555 (~35psi) weigh ~ 45lbs.
