What are these when fitted to the suspension kit? How do they work?

[heeman10]

Bump stops are there so that when you reach the end of travel in the suspension (ie if you drop into a deep dip on the road), you dno't push your suspension through the turrets. They're dense rubber that acts as a last shock absorber. You'll feel a dull thud if you bottom out your suspension, that's when you've hit the bump stop.

How necessary are they? do you need them when lowering your car 60mm on 15's?

[heeman10]

All cars have bump stops otherwise, as I said above, the suspension would suddenly be putting a lot of pressure into the turrets, so bump stops need to be there to absorb this pressure. I've been advised to reduce my original bump stops by 20mm when I fit my Gmax 35mm kit.
