I did a search, but didn't come up with much.

I was wondering if there are any height adjustable coil-over kits that dont come with the strut included for the Z. Similar to ground control or some skunk2 kits etc. Thanks.

 

Ground control did R&D their advance design shock system for the Z with their sleave coilover system. However, the position of the oem rear spring location coupled with their height adjustment system added up to the kiss of death for the project, both the advance design shock and the idea of marketing their coilovers for the Z. And I do want to point out that they were very set in the idea of NOT offering either product, simply not worth the effort to try and redesign things in the rear.

However, they did tell me that if I were to send them a pair of front Koni shocks that they could at least make the front's into coilovers. He even said that he'd be willing to turn the rear shocks into coilovers.

In the end I didn't take him up on his offer and I made my own custom Koni coilovers, which I've pulled from the car to chnage some part's around.

 

Thanks. Yeah, I wondered why with such a popular platform there werent any sleeve coils out there. Now I know why. Cool.
