Looks like I'll have more stuff for Neil to do next time my car goes to the shop then. I think I'm going to go:
Odyssey PC925 -26.0 lbs
Spare Tire etc -39.2 lbs
RWD (extreme version) -120 lbs LOL wishfully
Clutch Actuator -47 lbs approx
LWFW Pressure Plate -19 lbs
Exhaust Mod - 50 lbs think i have something similar already
Bumper Supports -40 lbs
Wheels - 20 lbs
GT3 Seats - 35 lbs
396 lbs
So ahem, Neil, next time I bring my car to your shop it should leave about 400 lbs lighter.
