I'm pretty sure i've got a set of -60mm springs....
I got given a box with random set and pairs of springs from different kits.
The lowest ones were purple, but i only used the front ones from that set for some reason, and rears from a different colour set, the front was damn low, so i'm assuming they are -60mm ones.
The car is gone now, so i've just got the rear springs left
Do you know what the the measurement would be?
I'll see if i can dig them out....
