Ian B Posted May 21, 2009 Share Posted May 21, 2009 I'd like to stiffen up the front a bit (2001 SV with 'standard' springs on adjustable platforms) to try to reduce the tendency to dive into the road and hole the sump on 'lumpy' roads  Any thoughts on what to look for, and where to source a good deal? Thanks. Ian - Slightly Vider SVelte model 😬 Edited by - Ian B on 25 May 2009 17:11:37 Link to comment Share on other sites More sharing options...

Stationary M25 Traveller Posted May 21, 2009 Share Posted May 21, 2009 I have been told to replace the standard 150lb front springs with 250lb springs ... which apparently works ok without any other changes.  Link to comment Share on other sites More sharing options...
ECR Posted May 22, 2009 Share Posted May 22, 2009 If you stiffen up the front without adjusting the rear as well you are altering the handling balance will almost certainly add understeer. Instead of the car diving into the road surface you may find youself driving straight on into hedges Depending on your driving style it might not be a problem, but a chat with Gary before you do anything would be wise Link to comment Share on other sites More sharing options...
John Howe Posted May 22, 2009 Share Posted May 22, 2009 250lbs might work on track but for rural driving will have you bouncing across the bends! Ian I have a few sets of springs including 200 and 250 lbs - you are welcome to have a loan...   JH Deliveries by Saffron, the yellow 230bhp Sausage delivery machine Link to comment Share on other sites More sharing options...

Englishmaninwales Posted May 22, 2009 Share Posted May 22, 2009 I did that, and as ECR says, understeers like mad! Link to comment Share on other sites More sharing options...

MAURY712 Posted May 22, 2009 Share Posted May 22, 2009 *confused*i am just trying to get an opinion about the front suspension,i have to replace the dampers and want to do the same as Ian B. I have to order all the parts with spring adjusting .... then there is a lot of sheep in my region and.... *rolleyes*i dont want kiss one of them for 250lb in front what is the correct spring rate at the rear? for a vauxhall C20XE.... is someone can tell me the rate of a rear standard progressive spring *confused*in my seven they are red... and what about bilstein M0 or M1 type? in france some 7 owners have tell me about damper code M0 M1 maybe the M1 bilstein damper is well rated for a 250 lb spring 🥰I prefer to kiss the shepherdess 🥰 😬 😬 1996 road legal 7HPC Link to comment Share on other sites More sharing options...
