adriantr4 Posted March 23 Report Share Posted March 23 I am in the process of rebuilding the front suspension on my '4, and have the Spax adjustable shocks which are about 30 years old. They "seem" ok on the bench - no graunching, strong resistance, smooth action. Clean too, no leaks. I did note that the "pulling" resistance is a bit more than the pushing. Is this normal? Anyhow due to their age I'm thinking of replacing them, and Rimmers have a sale. But... cheapest adjustable is Gaz at £145 a pair, whereas the standard shocks are £37 a pair. That's quite a price difference. I don't really need adjustable shocks, so should I put the ancient ones back on, buy the standard ones, or dig deep (and I have been Spending on the car recently) and get the good ones? Or ...?

stillp Posted March 23 Report Share Posted March 23 If you bounce a front wing down then let go, does it continue to bounce up and down, or does it return to normal height and stay there? Pete Quote Link to post Share on other sites

Thanks Adrian Yes, that is normal, you want the suspension to respond to a bump by moving up quickly, but to avoid oscillation the damper only allows the suspension to drop more slowly.

Bob Which is why you do not have dampers that are very firm. You can end up with ‘jack down’ where the suspension is compressed but the spring is not strong enough to extend against a very firm damper. Quote Link to post Share on other sites

Thanks Adrian TBH I would replace the rubbers and put them back and drive on. Stuart. Quote Link to post Share on other sites
adriantr4 Posted March 24 Author Report Share Posted March 24 Thanks for the advice. I'll will put the old ones back with new rubber, and to Pete: they seem ok, when on the car and the wing bounced it returned to normal height, behaving as expected.

stillp Posted March 24 Report Share Posted March 24 Well, if they pass the bounce test and show no signs of leaking, they don't need replacing. Pete Quote Link to post Share on other sites
