Greetings!

I just received yesterday my SPC Upper Front Control Arms and Rears from TH Motorsports, see under vendors on this forum (thanks Eddie)
The Upper Front Control Arm kit came with shims for behind the bearing hub and a bracket for ABS sensor.

Are theses for recessing the wheel outward from the hub, and intended for increasing negative camber?

Can anyone confirm this?

Do I need to install these, if my goal is to add positive camber to bring it back within the manufacture' range?

Camber alignment readings after suspension upgrade:

2005 model:
Front -1.4
Rear -1.9

2006 model:
Front -1.7
Rear -2.1

I attached pics of the kit and the installation instruction sheet. Along with the reading(s) from the alignment using a Hunter alignment rack.

I have been reading posts (struts, springs, tires, sways, and recently plenum spacer) for over a year now and decided it was time to post a question,
after many hours searching the forum. Also I finally got up the nerve to post! Appears a couple of other forums are really brutal.
Therefore I choose 350Z-Tech to make my first post.

Thanks in advance for any advice.

Curtis

Hey Guys,

Any advice would be appreciated? Has anyone got these installed? I searched the forum under SPC and several folks have the rears: martz, Ronin Z, Enjuku Ray, Ninja350Z, SmoothZ?, westpak, K Shep, JTS2005 ?, Domino, scathing?,

Vendors feel free to join in. (bigz88, illz33, Intensepower, buzzmountain)

I have read several posts by all of the above and respect your opinions and advice. I almost went with Toykilla' mod on the Cusco although opted to go with SPC due to more positive camber they offer over the +1.0 (after Josh's mod) Cusco. Toykilla any advise on these shims?

Again thanks in advance!

I read on one of the forums that the shims are only needed on severly slammd cars. I'd try to get your car aligned without using them, and see if you can get to the specs you want. That said, it's only 4 bolts per side to install the shims, not too hard to install.

By installing them, do they move the wheel outward from the wheel well? If so, then maybe a consideration for a wider looking wheel even if it's only 1/4"- 1/2". Unless these shims(spacers) will add stress to the wheel bolts which could be harmful? Dont know. Or could they be used to clear the metal flange that Toykilla had to bend on the Cusco mod?

A member by the SN of Renovatio should chime in when he's able. His Z is pretty slammed and is going even lower. He should know the answer to those questions, I hope.

I finally got around to posting an update after installing the front upper arm kit and rear camber kit. After three technicians looked at the shims we opted not to install them.

Their product is well manufactured, a selling point for me is the amount of positive camber (for saving tire wear) they proclaim which they do live up to their specs. The rubber bushings on the upper control arms (same type as Nissan) for comfort, and that the dust cover for the ball joint covers the entire area (not like Kinetix).

The upper control installed nicely with a snug fit, well manufactured. We new up front that a metal flange on the underside wheel well would need to banged back for clearance of the outer arm where the ball joint is located. We also shaved about 1/8”of plastic (see pic) it’s all underneath and cannot be seen, shit I can hardly see it from the pic.

The rear camber kit took the longest, allot of time spent hogging out the toe slots on the frame. In the end we did not need to even install the toe bolts as the range to bring the toe back into spec again to save the tire wear, not for track setup. If so then I may want the toe bolt installed, but for getting the car back into spec we had enough with the original toe bolt, therefore only one of the two cars had the toe bolt installed. Camber arm is sweet and a fast install, which was needed with the rear spring at a 1.0” drop.

The results were amazing once dialed in on the alignment rack. The fronts we were able to go from a -1.4 on the Silverstone and -1.7 on the Interlagos Fire (IF) to -0.3 on both cars. Wow! We settled on close to nominal setting of -0.6 for both cars (save them tires). Our only problem was bringing the caster into range, we started out with arm set to dead zero, and by adjusting the caster on the arm would give up camber. So we set it on dead zero and achieved the -.06 camber. We are going back to the rack and adjust the caster on the arm and hopefully at least get the caster in the high range of at least 7.4. with a camber of -.08. It’s about all we ask can for.

As far as the ride, I could tell right away that the car felt like the tires were planted more firmly. Braking in a dead straight line, the car did not pull at all, braking in corners was solid. Cornering, well let’s just say that I feel more confident taking corners a bit faster. Overall I am very pleased with my current suspension setup. Next mod, SWAYS, hopefully I will not give up that comfort with the sways (at least not allot). My choice would be Hotchkis.

Original Upper Control Arm with Koni Shocks and H&R Springs


The instructions called for using the original ball joint stud seat (the shiney black piece)


SPC rubber bushings, comfort, comfort, no noise.


This is where we needed to make clearence for the control arm, banged a flange and cut out a small piece of plastic.


Installed product.

Cool, I notice that you're from Sacramento =D

Did they install the springs and arms too or just the arms?

Was it your Silverstone that had the spc arms installed? If so your caster can be corrected, it looks like the ball joint was set to -1.5deg caster on your left side.
