Hi Pete
As I said on the phone is about bump / rebound rates thats is the main problem , you have to find out the bump / rebound poundaged and go from there
The main reason why the back end of any cossie gets light is because the front suspension is far too soft , when you brake under high speeds the wieght is all transfered to front causing the back end to go very light
but when you have proper suspension on the front it stops all this
see this is a misconception with most of you lot mension Bilstein and the first thing you lot say is "bloody hell they are too hard " and yet most of you don't even know what they are like on the car , no offence
Tarmac's start from 400/150 and go up in every 10lbs on bump and rebound all the way up to 650/250
Gravels start from 260/110 up to 380 on the front
and one good bouns with the gravel mag rears that they are light weight magnesuim alloy ..one spring is heavyer than the 2 shocks put together
I dont care what anyone says for what they
COSTthey are the best out of all of the normal coilovers ...... i know i have tryed loads of coilovers they either leak/break or bend one of the 3.....
I would only take these of my car if i was to have something like proflex /ohilins/ Reiger all with remote resiviors of corse
cheers Marco
