Lack of Camber in an RX-3 with RX-7 struts
#26
Rotary Loco
He took the RX-7 lower control arm and "attached" a rod end to the inside, allowing me to "dial" the bottom of the control arm out to regain the camber. He fabricated a bracket and welded it to the frame rail where the stock sway bar mounted and used the locating rod from a RX-7 with GForce spherical bearings. He used an off the shelf, aftermarket sway bar and arms, going through the frame rails and attached it to the strut itself.
I will pm you with photos, the ones I took are to big to attach.

Hello Chedstar
Can you post the pictures on this thread?
It will help others learn about other options to get the right suspension settings
thanks,

Thanks for that tip, will be sure to pull out the old mason line and check to see if my tie rods are falling inline with the Balljoint & rear axle center line...
Billy what every happed to that CAD file i sent you? the caliper bracket to mount the FC calipers on the rx2 was the same as the ones you make for the 1st gen... The only thing you needed to fab was the bearing sleeve... Im confident that the drawings on that file could have worked wonders for the few old schoolers on here, because the person i got it from also built a few kits and they're still running around Australia with no problems...

I really never liked the idea of the outer sleeve that is needed. Could be done though.
I think we are going to continue with our Mark II style kits for the rx2 and rx3.
I *may* look at the sleeve again to do the Mark I style.

I will take some photos with the lower settings on my camera tonight. It is really a neat set up as there is a large amount of adjustability in the front end.

I had the same problem with my old ITA RX-3. Dave Gilbert at DGEMotorsports.com came up with the front end I have on the car now. This is an option, though it is a lot of work. He took the RX-7 lower control arm and "attached" a rod end to the inside, allowing me to "dial" the bottom of the control arm out to regain the camber. He fabricated a bracket and welded it to the frame rail where the stock sway bar mounted and used the locating rod from a RX-7 with GForce spherical bearings. He used an off the shelf, aftermarket sway bar and arms, going through the frame rails and attached it to the strut itself.
If you are not running IT any longer, are you running slicks? With slicks you only need 1+ degree of camber; not the 3+ that is required for "treaded" tires.
I will pm you with photos, the ones I took are to big to attach.

The first photo is the bracket that is bolted to the subframe, through the front cross member/engine mount. Second photo is the sway bar end coming through the frame rail, and the arm going back to the strut. Third photo is the rod end connecting to the strut. Fourth is an underside view of the sway bar going through the frame rail and mounting bracket. Fifth, is the RX-7 lower control arm, with the rod end threaded through a bracket.

These first two are the rod end on the lower control arm. The last one is a close up of the bracket for the locating rod. You can see, the sheet metal flange along the frame rail was in the way so we ground it down and then welded the two pieces togther.

Jeez that's a lot of custom work there!
Billy, if you're listening... can you please make us RX-2 and RX-3 owners some custom subframes like you did for the SA22 chassis RX7's? PLEASE!!! I could car less about keeping my RX2 stock if it ment having better supension, brakes, steering (rack and pinion).

Guys, I am open to it. Biggest thing we run into it the availability of the stock parts to design from. The brake kits have been on hold for a few months now hoping to find some stock rx3 bits to finish the designs.

Thanks for posting up the pictures...look a lot complicated that I figured. I was hoping with the 1st gen lower control arm I can use a custom sway bar similar to the rx7, but thats not the case as the tension rod is mounted where the sway bar mount location. Is that an rx7 tension rod?

Yes, it is an RX-7 tension rod. It was a lot of work, but as I still race this car, we wanted as much adjustability as possible in the front end. With this set up, we can adjust camber from the camber plates on top, or the rod end on the bottom. We can preload the sway bar, as well as tighten or loosen the sway bar.

What about instead of rcas running nrcas?
These Negative Camber RCA's will provide 2.8 degrees of camber on a car dropped 2". On a car dropped 3" they will provide 3.1 degrees of negative camber (these figures are IN ADDITION to the camber your car already has, so if you already have 1.2 degrees of camber at 2" drop, then you would have 4 degrees overall of negative camber)
These units will also widen the front track of the car by 25mm per side (50mm overall increase in front track). Used with Camber plates, they will allow you to run moderate camber with a much wider track or absolutely insane amounts of camber 5+ degrees.
