Hello

I'm in need of a set of coilovers for my car.

Chassis is currently set at full weight completed car ride level.

Therefore i can measure the length the shocks would be in the final configuration.

But that said, how do i work out the actual length of the shocks and springs needed ?

I'm going to use Gaz components seeing that they are affordable and good.

Do i use the current measure (around 11 inches) and use that as the central reference seeing that Gaz coilovers mostly seem tohave 4 inch travel ?

How about spring length ?

Thanks

Have you tried Protech?
https://www.protechshocks.co.uk/

They have been very helpful to me in the past.

I think the basic rule of thumb is, you want 1/4 of the suspension travel to allow the wheel to drop into a hole. and the other 3/4 to take care of bump.

the closed length will dictate what the open length can be.

Give protech a call, they should be able to advise.

Thanks

So that would mean approximately that with a shock length at rest on the car of 11 inches, i would need a shock with 12 inch full open and 8 inch full closed length ?

I had seen protechs website once via a google search i will give them a ring
