Looking at feed back and options for rear dampeners for a PC Challenger running heavy duty GVM +150 kg springs. The front Drummond Motor Sport struts work a treat but rather disappointed with the Bilsteins. They were marginal with mid rate rear springs but rather struggle controlling the heavier springs. One option is revalving them. Another is different dampeners.
Lot of hype on dampeners but rather hard to get sensible information. Dampeners are one thing lot of people on the forum have had issues with on long corrugated road runs. Not a fan of cynical marketing Mexican or Asian dampeners with trendy names, and wish to avoid foam dampeners as once they over heat they are "dead".
Koni's are adjustable but are not approved for use by Koni on the Challenger. Part of the reason is lack of clearance with the big bore. Koni's would likely need to be correctly valved and setup for the much higher spring rate I am using rather than the one setting suits all.
Sadly Drummond Motor Sport do not make a suitable rear dampeners. The ones I trailed were too long and were destroyed when acted as impromptu bump stops. But boy did they give a great sense of control.
So anyone had luck with dampeners using extra heavy duty springs?
