thanks for that. i have gmax 40 mm lowered springs and have 2 grooves im using the top grove. but the thing is that ive installed the shock and spring but the car does not lower. ive even installed spax 40mm springs on standard shocks but still the car doesnot get lower. the way i done it was put the spring in the shoc using compressor and then tighten the top bit of the shock. when i put it in the car i put the top bolts ina nd the bottom arm. the spax springs have more coils coiled up at the top of the spring then the gmax springs, why is that?

thanks
