[lyndon_breeze]

i know there are heaps of these, but i just got springs that will lower my car 75mm, and got standard sus, i just wondering if it was to low, i know the whole 100mm from the ground, but i dont wanna do all work and have to take em back out

If you are going 50mm or lower that stock, you will also need shortened shockers. If you do not also do the shockers, the lowered springs may fall out.

75mm low would be ultra lows ?? Approx Low =25mm, SuperLow =50mm
There are plenty of cars on here with ultra lows. Do a search.
