ground control coil overs?

how good of a setup are they?

I know there are more expensive ones out there but will the groundcontroll work well enough?

how much can you adjust how high your ride sits?


one last thing how would you go about installing a system like that? and which shocks would you guys recomend?

koni yello, kyb AGX, or gab?

I've got them installed on my TII with non-adjustable "blue" tokicos.

Height adjustability is "scrape your bottom" to "mini monster truck." At stock ride height on stock TII wheels, the coilover's are adjusted 5/8 of maximum height. The NA wheels would be slightly lower of course.

Installation's pretty straight forward. Seemed like I had to remove the stock dust cover and bump. You MUST use an impact airgun to remove & install the nuts at the top of the struts.

One thing I thought was odd is the 3" hollow screw shaft you use to adjust ride height just loosely sits on the tokico's welded on lips. Normally it stays in place as your shocks compress from gravity, but you would think if you topped out while in motion (ie tires off the ground) it might raddle around and possibly kink & break. So far, no issues though.

The good - much better handling, more responsive during turns & transitions, etc.. Whip your friends at the racetrack.

The bad - bottoms out in potholes & rough road gets annoying but tolerable.

You might want to get your car corner balanced & weighed before the alignment. I haven't done this, but I believe you're able to compensate for weight distribution better somehow.

Before you set the permanent ride height be sure to "lock down" the coilovers and ride around the block a few times. This will make sure the struts are compressed fully. I measured ride height from the ground to the wheel well and adjusted each coilover's height appropriately.

Also the tokico "white" adjustable strut's soft setting might help with rough roads, but I don't think it's worth the extra cost.

I adjusted the height so I can still squeeze a jack under the car which I think is 1/2" lower than stock.

They work well, I have had them on my car over 5 years now. I would like to have some of the more expensive setups that are out now, but these work just fine. If you do not already have shocks, and are also thinking about getting camber plates down the road. Find out what camber plates you want and then find out what shocks will work with those camber plates. trust me it will save you some headaches or some cash. If you lower the car as much as the coilovers allow, you will want some kind of camber adjustment.

The GC coilover setup for the fc comes with threaded collars that you place over the struts. The total adjustment available is determined by the height of the threaded collars. From memory, the collar height is only about 2.5 inches in the front and maybe 4 inches in back. As a practical matter, the front suspension adjustment is maybe an inch either way. Any decrease in ride height decreases total suspension travel. So spring rates will have to be increased to prevent coil bind and suspension bottoming.

cool

I think the coilovers normally come with their own smaller springs, at least the setup I bought did. This completely replaces the normal spring/strut setup with coilover/strut.

GC will be able to make recommendations. But a standard front spring recommendation is around 7" x 400lb. The camber plates will get you maybe 3/4" drop over the stock top mounts.

Another thought. Some of the more expensive units allow changes to ride height without changing spring lengths or rates.

Also make sure to ask for qualified recommendations. It is quite possible to end up with a car that handles much worse than the stock set-up.

The GC setup should come with their own coilover springs. like the above people said tell them what you want to do with the car, suspension wise. autox, drag, road race, and they will be able to recommend what spring rates to go with. Up to a 1" drop and you shouldn't need camber plates. Anything lower than that and you will proably need them.
