Camber plates/stack height & Bump-stop Q's

[royalflush313]

I somewhat recently switched to GC coils with GC revalved Konis.

I'm not that low (front fender arches match up with stock diameter wheel/tires, no tucking) but I find that the car bottoms out too frequently and is pretty bouncy.

- I have the GC bumpstops which are pretty long - can I safely cut the existing bumpstops to gain some travel? How much can I cut off?

- Which camber plates (or other alternatives) will provide the lowest stack height? I don't need anymore negative camber out of these, if anything, positive, my main goal is to gain the most suspension travel.

Thanks

you're running GC coilovers and stock strut bearing? I am running IE3 springs and GC konis on the stock strut bearing and have about a thumbs width of front damper travel before it hits the GC bumpstop. It doesn't feel like I bottom out much, or at all (though I have yet to hit a big pot hole) but I must be running on these bump stops. And I have about 1.5 finger widths of fender gap in the front.

I think any camber plate will help your situation. Go with the GC camber plates, that reduces stack height by a couple inches, then you can run the same height as you are now and gain all that stack height back in travel. Though, you could also check out the motorforce camber plates, they may give you even more travel. Isn't there a group buy on GC stuff right now?

Also, GC has two different kinds of bumpstops, 1 that is longer and more progressive (that I have) and then 2 that is shorter and stiffer. Maybe if you have the soft ones, swap them out for the stiff ones.

edit: what spring rates are you running? my IE3s are only like 300 lb/in in the front, you should be running atleast that. The bounciness is either too little damping or you're riding on the bumpstops and the dampers can't deal with that kind of increased stiffness.

thanks for the reply.
Front rate is 300lb/in, and yeah, I am using stock strut bearing.

I'm defenetely going to invest in some camber plates. But like I said before, main reason for it is not for camber adjustments, but to gain suspension travel. So essentially I want to know which camber plates will give me the shortest stack height. Most camber plates I believe can go +1/2 degree, and more than 2 degrees negative, which is more than enough adjustment for me.

GC bumpstops are huge! I'm defenetly going to trim them.



Mine looks like the soft, progressive 19-24mm strut. How much of it can it safely trim off? I know that Bilstein bumpstops are tiny compared to the GC ones that I just bought. Can I cut it so that all I have is the first-knob (if that makes any sense) ?

I'd try out the camber plates first before you go trimming the bump stops, they might provide enough travel that you don't bottom out. I would think that trimming the bump stops too much would run the risk of blowing your shocks.

Yeah good idea.
I guess my options are IE, GC or Motorforce.
Now, does anyone have experience with all three, or at least the two, so you can tell me the stack height differences?

[Digitalwave]

I'm sure if you called up the companies they'd be able to tell you.

and I don't think there's going to be much difference between them all. They'll all most likely be with in a half inch of each other. Any of them will give you what you want.
