Nice GT, do you know how much weight has been removed precisely by the GR40TT kit ?

rarnouxp, It depends on which Griggs suspension you go with, a full GR40TT or GR40RT will shave apx. 200 pounds off the front end when the aluminum drop spindes are used. The GR40TT/RT rear suspension will actually add some weight because of the torque arm and Watts link, but this is to the car's weight distribution benefit, IMO.

NICE, one question though, what kind of transmission is in the car?
