I'll put the car on a hoist tomorrow (its one where the tyres sit on a platform...not on the car rails) to tighten it all up properly.

Question time:
ould it matter if i loosen it while its on the ground or should I jack up each corner and loosen before I put it back down and tighten?

So I noticed the groove now. But i guess you cant change it while everythings on the car? So putting on the highest perch would compress the springs more, making the car sit lower? :oops:


I would raise it on the hoist, loosen the key components (anywhere there is a bushing) and then re-tighten while on the hoist. The objective being to tighten with the weight of the car being supported by the suspension.

As for the perch height. The lower groove will lower the car. You will find that tail will sit lower if you use the lowest perch on the rear dampers. If you want the car to be even then use the middle perch at the rear and the lowest perch at the front. I'm sure someone will pipe in if I got that wrong.

Car didnt seem to settle at all really, but the springs were 2nd hand so that might have a bit to do with it.


Using the jack like that will work, altough I usually jack it up to the point where the car starts to lift of the car stand. Remember that the car will be sitting lower on King springs (assuming they are the lowered springs). I also believe the bushes play a much bigger part than the springs when allowing time for the car to settle. Remember that the bushes are at each pivot point and will put up some resistance as car tries settle under its own weight.

Ps don't raise the car off a stand unless it is stable, and certainly not if anyone else is under the car or close by.
