I just got my ground controls and I was wondering are they supposed to have the wrench to adjust them or can you buy a wrech? If not do you just turn them by hand thanks for any help.

 

No wrench needed. They turn by hand.

 

When your done, don't overtighten that allen set-screw. They become harder to loosen over time...

 

on that note, anti sieze the set screw!!!!

also, they turn by hand when there's no preload, but my fronts are preloaded pretty heavily (not intentionally) so it helps to have a spanner wrench handy. I use the spanner wrench from a friend's set of progress coilovers.

 

thanks for the info guys, so if the wheel is off the ground they will turn by hand. Thanks again.

 

The "off the shelf" kit will. If you go with longer custom springs, rates, etc, you may have to preload them like bad-monkey. If your just lowering the car, you have nothing to worry about...

 

I'm sorry I'm new to the lowering stuff. I have koni yellows with GC's custom rates at 450 front 400 rear. Do I have to preload if so what is preloading and how do I do it. Also if there are preloaded how would I adjust the coil over height. Thanks again.

 

Well, normally when you install GC sleeves, the springs aren't long enough to completely fill the gap between upper spring perch and the lower spring perch. This is so you can lower the car as much as 3 or 4 inches, and still use the same spring when you raise it back up to zero inches. This also means that when the shock is fully extended (or the suspension droops), the spring comes completely loose (by about an inch or two). If you twist the GC collar up until that gap disappears and the springs seat at both ends, you have preloaded them (barely). If you keep twisting the collar up and to compress the spring, you are preloading the spring even more. The problem is that it becomes impossible to spin the collar your hand. This is why you would need a spanner wrench to go further up...

Like I said before, since you have custom rates, it all depends on what length springs you got. Most likely you won't have to worry about preload at all. If you do, you'll know long before it becomes an issue on the car...

 

thanks that's good info, now I think that this is my last question, what is the benefit of preload and what are the effects of not preloading, what could it do to my car if I need to perload and don't.

preload is a boogie man term. doesn't really affect suspension performance much at all. there's a case to be made for a little preload (so the spring doesn't flop around when the suspension decompresses) but as far as making the car "faster" there's no reason.

 

As long as you get the ride height you want, preload doesn't matter.

 

ok thanks alot guys, I'm going to do the install now.

 

thanks guys everything turned out great.
now alls I have to do is get rid of those beefy 65 sidewall tires!
