Swampy442 Posted May 29, 2013 Share Posted May 29, 2013 Ive got a set of struts that are height adjustable via the bottom mount, but also have helper springs, how do I set the spring preload up? Minimum amount? Do I have to dial a certain amount it? Are they even required on a road car? Have googled it up but can find no solid info....

Tricky-Ricky Posted May 29, 2013 Share Posted May 29, 2013 From what i have seen of helper springs, they can be there just to prevent spring displacement when jacking the car up, or as a form of progressive spring setup,/. Are they pretty firm orelativelyly soft? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 29, 2013 Author Share Posted May 29, 2013 Pretty soft mate, Ive read they were mainly used just to hold the spring in place, and I assume they will be coil bound when the car is on the ground but I cant see that.

ManwithSupra Posted May 29, 2013 Share Posted May 29, 2013 (edited) Helper Springs are there to stop the main spring from bouncing around in their seats when going over bumps etc. They are not very stiff and will be fully compressed when the weight of the car is on them. Adjust the preload ring as required and then set the height with the bottom mount. Preloading the spring is part of corner weighting; unless you have car scales then you are not going to be able to do it properly. That said corner weighting a road car is not that necessary.
