I hear so many bad things about the ebay coilover sleeves, but not about the ground control's.

Whats the difference besides ground-control using eibach springs?

robtechfabrications

ground control is anodized aluminum...the spring perch has a screw type locking deal instead of 2 rings that tighten against eachother so the perch stays where you put it and doesnt move...they come with rubber rings that go on your strut body for a tighter fit and of course the eibach springs are way better quality than the ones that come with the ebay kits...altogether its just higher quality pieces and a more reliable pech setup. and when you order the kit if you want stiffer spring rate they'll send you stiffer springs...they have tons of spring rates to choose from

Ok.

A guy at work bought some ghetto ebay coilovers for his car. His actually came with the rubber o-rings around the strut also, the threaded shock body was also aluminum as well. It did have the 2 discs instead of the screw locking your talking about.

Basically, what makes the groundcontrols not unseat themselves compared to ebay coilover sleeves.

I'm trying to decide between an agx / groundcontrol combo and a set of full coilovers.

Reason i am thinking i want to go the AGX / GC route is the ease of replacing dampers compared to having to ship coilovers off to be serviced and the high price of having them repaired.

My car is a streetcar, that may possibly be used for auto-x and the very rare track day for fun.
