rear leaf spring tuning
!
Ant ideas?
Ps im I'mnot allowed coilovers or anything like that!Ok, so I know front springs are easy to get hold of, and cos I'm wanting to race my 340, ideally I need to be able to make the back stiffer too, is this possible with the old leafs? I've been racing for a good few years, although not in a volvo! So I understand the difference between spring rate and damping. I can of course get really hard shocks, and make the suspension seem harder, but its not really the right way to go.

Take them to a spring shop or blacksmith and get them retempered. They loose tempering through movement induced stress throughout their life, so should be a noticeable improvement.

And if you havnt got a local blacksmiths, try training ants to retemper it?themightybaggins wrote:!

Re: rear leaf spring tuning
landrover defender shocks at the back for increased dampning and just take a second leafspring from the scrapyard, cut off about 20 cm's from each side and fit it underneath your original leafspring.
just like this: http://motionoffroad.com/catalog/images/mjleafs.jpg (yes i know this is not volvo and this is factory default with multiple leafs)

Re: rear leaf spring tuning
A Spring company here in Norway lowered my leafsprings 7cm, paid like 60£ for both. Better to lower the spring than using blocks
