Help SPC Front Camber Kit Rattle
I was finally able to install my test arms today.
In short, the arms, being shorter, provide less positive adjustment. However, the arm's full travel lands them in the intended pocket in the fender well.
A note though, it that maximum positive camber adjustment on the arms cannot be used as the leading edge of the adjuster will contact the upslope of the steel forming the pocket. The fix here is to slide the camber adjuster about 1 to 2mm in from the most positive setting. Also of note is that I installed with 1 notch of negative caster. If you run 0 caster, the camber adjuster would likely need to be slid in 2 to 3mm instead of the above.
My install was very quick and dirty last night, so I didn't get any pictures or measurements. I'll do that tonight and send all of that info to SPC.

It is looking that way. Right now the G35 arm looks pretty good for those running Eibach or similar drops in the front. I am running max camber adjustment and -0.5 caster on one side and do not hit metal-metal. I bottom out the suspension travel before the arm hits the fender.
Finagle hits with his coilovers and he is about 1/2 to 3/4 lower than me which is why he mentions backing off on the caster adjustment.
So making progress.

I'd say for actual driveability, the G35 arms are a no-brainer. At least the leading edge of the arm itself doesn't hit anything. The only remaining problem is the top nut hitting the top of the fender. It seems there are only two ways to mitigate this problem: 1- shorten the height of the balljoint by either removing caster adjustability or by some other means, 2- by installing the SPC provided urethane washers as additional bumpstops.
option 2 is less preferable, but after driving today with negative caster, I really don't want to give that up! the car is able to be thrown into corners so much easier, it just feels lighter.

I agree with the caster comment. Since the camber/caster adjustment mechanism is +1" over OEM, if they can come up with a design that gives back 1/2" and uses an offset design to eliminates the place where you are hitting, then I think they would have a winner. But even with that magic, I think it is going to require some bumpstops with those going real low. I just don't see how you can get around it due to the fender? Thoughts?

Just installed my SPC rear camber kit and dropped on Eibach's for my X coupe (1.9" front, 1.6 " rear). The shop who test drove my car said that there's a bit of tire noise on my front 20" tires and said that because the front wheels are off by 2 degrees, I definately need a front camber kit. The one I got from Andy doesn't have the bumper stops and the car feels weird when driving. I literally feel every bump now, but I guess that's the cost I pay for dropping on Eibach's. Now I don't know what the hell to do. Do I request G35 arms for the front? Do I get the front bumper stops? Someone please help! Thx in advance!
The word I got is that in order to adjust camber in our cars the arm has to stay the way it is. So the temporary fix will be the permanent fix. Im telling you what I heard. I cant prove you wrong or right. Is up to SPC.
Here is part of an email I have from Jeff Pagani @ SPC.

Dave,
Based on the feedback we are getting from you and John, it looks like we will continue down the road with using the G35 arms for the G37 application. Bump stop washers will become part of the kit. We will still work on improving the design as much as possible.

I would give it another week or so until SPC issues something official.
