Default Adjustable Rear Camber For Gs98-05

Hi, dear GS car owners, Good News! Rear adjustable camber kits for your car finally here. Our regular price is $399.99 a pair, the first 10 callers to order these kits now will be able to get them at a deep, deep discount for only $299.99 pair. Please call Sandy or pm us to order. Thank you.

These front & rear camber kits actually are lowering blocks, your car has to have coil over suspension in order to install these camber correction. These blocks lower your car by approximately 1 inch, so you have to adjust the coil over suspension higher by 1 inch, then your car will has less camber.
For the rear camber kits are adjustable, we made two different inserts that you can choose which to insert when installing in the car determine by how much your car camber.
Very, very important note! You have to align your car immediately after you installing these kits, driving without aligning can result in severe tires wear & handling issues!

We have a demo on our site: www.exactmotorsports.com

That's great news, thanks!
How difficult is the installation? It appears to be bolt-on, but I can't tell for sure.

On the RCAs for the front... I've been thinking about these
and I don't quite have it straight in my head how they fix the negative
camber issue... the upper arm still moves up and inboard (due to the
"tilt" of the upper arm when the car is lowered and the RCA pushes the
top half of the suspension upwards) so camber would likely
still be more than OE (?)

Default First Exact Rear Camber Kit Installed

I just installed the rear camber kit in which I'm using Tein CS V2 coilovers that were already adjusted for maximum drop.

Installing the camber kit allowed me to drop the car an extra 3/8 inch. The rear tire on 20's is now tucked by about 3/4 inch.

I actually had the coilover raised about 3/8 inch to compensate for the drop from the camber kit. So that means the camber kit allows a maximum 3/4 inch drop if you don't re-adjust your coilovers back up.

I just aligned the car yesterday and am easily within factory spec.

Camber = -1.3 left & right
TOTAL Toe = 0.00

VERY VERY IMPORTANT NOTE: You should have your car aligned immediately after installation of this kit. Driving without aligning can result in severe tire wear and handling issues.

Now that my alignment is done, I'm totally within spec, the handling is great, I have more drop using Tein CS, My Wheel edge is flush (not hellaflush) with the fender and ZERO rubbing (with shaved inner lip, no fender pull or other fender mods)


Tucked 3/4 inch



Camber and Toe In Spec (No Adjustable Toe arms required)

Fantastic news Glen, thanks for the update!

The rear kit looked like it might lower the rear control arm a bit,
so I thought this might provide a bit more drop.

I wonder if the RCAs and rear camber kit work on the first-gen
GS as well? I might try a set of the RCAs in my brother's '94 GS300,
perhaps I can machine a bit of material off to make them 15mm thick-
otherwise it'll make his car too low when combined with the Eibachs.

A 15mm thick RCA combined with the rear camber kit would provide a
nice drop and great ride quality when combined with a set of standard
lowering springs!

Even without Glen's specs, you can visually see zero camber on Glen's car, I've seen Glen's before and after as well as compare to my -4 degrees camber when we both got the alignment done together. For those that worrys about camber wear and goes through tires left and right, this prduct is for you but REMEMBER TO GET YOUR ALIGNMENT DON'T RIGHT AFTER. this is adjustable, you can adjust positive or negative camber, Exact can chime in with the details. Time to update my rear's bracket John.

feeling stupid... what are these made of? it's obviously not billet aluminum.... plain steel?

also... how exactly does the camber adjustment work in this rig? i know you have to turn an eccentric bolt/bushing to change the camber, but how do these "inserts" come into play?

how do these compare to the spc rear camber kits/bolts?

i recently installed mine. they say you can get a full degree out of the spc, so after install, i had my alignment done, managed to get it to about -1 degree in the back.

car is dropped to pretty much where the tires are just a little tucked beyond the fenders if u look from the side.

Welded steel construction.

The mounting location of the lower suspension-arm mount is moved in-board to add more positive camber. There are 3 positions, each adding about 1 degree of positive camber.

I have mine on the first setting (+1 degree) and am able to be at spec. If GSing430 uses this kit, he will probably need to use the + 2 or +3 degree setting. C'mon Michael DO IT !

The EXACT RCA will get you in the ball park camber angle and then the factory "eccentric bolt/bushing" you mention is used to do the final adjustments, either more positive or negative.

I just completed an 800 mile road trip this weekend, which included some twisty high speed roads.

With the Exact RCAs my rear stability feels much more controlled and tighter, than when I drove this particular path a couple weeks earlier.

I suspect the reason being because the Exact RCA gave me an improvement in roll center and also the ability to align the camber "correctly" for handling.

Some of these high speed turns (70-80mph), involved both steep uphill and down hill grades. Some of the turns had some nasty dips or bumps near the apex to the corners, where my rear would previously get very unstable.

I am happy to report that I can now take these turns with NO DRAMA.

For those who are serious about handling while running at a very low ride height, this kit is Da BOMB !

Even if someone did not want to lower their car any further, I believe installing these EXACT Front & Rear RCA's are still valuable to improve handling, due to improved roll center angles and camber alignment.

I estimate the drop of the rear RCA to be 3/4 inch.

The Exact Front RCA gives about 1 inch drop, but the blocks themselves are 1.5" thick, which is much thicker then any other RCA on the market (Youzealand, SAGE, etc.)

If the lower suspension arm is the same as the 2nd Gen it might. Otherwise some modding may work. The kit is bolt on, but you could permanently weld it on if needed.

Looking at the front RCA's it's do-able by any good machinist.

YOU ARE SOOOO RIGHT BOB !

By using the Exact front and rear RCA's with lowering springs you'll achieve about 1 inch more drop and maintain good ride quality without going over to coilovers.

Pics from the Exact site: http://www.exactmotorsports.com/GScamberkits.html


Installed photo of the "PRE-production" model. Final version will come Gold Cadmium plated:








In the photos below you can see the removable insert that allows the mounting hole to be located in three positions by just changing out the insert.



Left hole position (shown in the picture adds about +1 degree camber)






middle hole position (shown in picture is estimated to add about +2 degrees of camber)




right hole position (picture not shown) is estimated to add about +3 degrees of camber

I'd like to see Gsing430 or someone try out the middle or right hole positions to verify the actual increase in camber for those hole positions.

As of this posting, I can only report my measured camber from the +1 degree hole position.
