Does anyone positively know if the Ground Control top-mounted camber/caster plates are STS/X/U legal? If you don't know these plates, they are the ones that use 5 bolts to secure to the top of the strut tower - basically giving you an inch of additional bump travel.

My impression is they are legal since the strut is still located inside the strut tower mount and drilling additional holes are allowed by the rules. My only confusion is whether or not this constitutes changing a suspension mounting point - I would lean towards no, but again, I'm not 100% sure. Suspension travel changes and ride height are legal per the rules so there shouldn't be an issue there.

I didn't see a previous discussion about the STS/X/U legality of this part, but if there is one please point me in the right direction. Thanks!

I was recently talking to someone else about them and after reading the newer rules it appears it would be legal. The exact wording is:

"The following allowances apply to strut-type suspensions. Adjustable camber plates may be installed at the top of the strut and the original upper mounting holes may be slotted. The drilling of holes in order to perform the installation is permitted. The center clearance hole may not be modified. "

If they are illegal because it changes the upper mounting point of the bearing then all camber plates would be illegal as thats what they all do.

You guys rule! I've never seen that allowance and was worried about these plates for ESP next year. Same "holes may be drilled" is in there, except in SP, we apparently can't touch the center hole, which is OK by me :)

afpdl, I agree with you - I could just see someone throwing a fit because the actual mounting surface is raised...should be a non issue.

Also, if you are thinking of using these plates, be aware that camber and caster adjustability sucks with the plates they come with. The bearing carrier interferes with the circular opening in the strut tower so if you go max negative camber, you can't do anything for positive caster. D_REX designed some alternative plates that fix this issue but I haven't tried them. Also, the plates bend easily...mine are starting to bend. They are going to be sent back for replacement under warranty but I'm not sure why they are bent - the GC rep said I was either coil-binding or bottoming out, but I have no evidence of coil bind and I haven't been bottoming out (at least that I know of - need to do some testing).

I would still be running my PDE plates if I didn't need more bump travel.....

Have you looked at D_rex's other fix for more travel?

I talked to GC 2 weeks ago and they *just* finished designing some new plates that do not have either of those issues.....

yes but I am not running Koni struts :( otherwise I would be hitting him up for a set!

Tom, spill the beans dude! I sure hope the old setup can be retrofitted to the new design...

Nothing to spill as far as I'm concerned :)

Give GC a call, I don't have them yet and probably won't for a while.
