I'm a big big ebayer, and I follow the company on ebay, saw the coilovers for 510 and thought I'd give them a go, ive only had them on a month, however the man that fitted them I know very well, and hes been dealing with modified cars for 30 years, he said they felt really sturdy and he'd say theyre a lot better than a lot of other coilovers he's fitted.
The ride is adjustable and its a bit too soft at the mo so I bounce about a bit, but im having the ride adjusted on monday to be more rigid and stiff,
But yeah, I dunno, they seem good
