Rx-2 suspension modifications?

sen2two · 05-09-2013, 06:01 PM

My 73 Rx2 has RE speed coil overs up front and out back. (using miata shocks in the rear)

And a 1st gen rear with ladder bar, Not just 80's, but late 80's tech! lol... It's good. But i have bigger plans. (I have also put GSL-SE front strut, hub, ect. on an old rx2. Requires a little adapter plate that mounts in between the SE strut and the Rx2 control arm. But it's really easy to make)

Front end plans:

I plan to mount the engine on an aluminum plate that fits from one side of the frame to the other. Then cut away the excess subframe leaving nothing but the suspension bits bolted to the frame. Then remove all that, take some measurements and make some tubular control arms and mounts that will be welded to the frame. doing away with the front sway bar as well. Then use a VW or similar rack and pinion steering that will mount behind the engine. Sounds weird, but all in all pretty basic if you have decent fabricating skills. Imagine the front end weight loss as well. Which is my motivation.

The rear will just get a cut down and built GSL-SE rear with an updated adjustable 4-link and ladder bar set up with qa1 coilovers set just inside the frame mounts. Similar to a drag car but not so aggressive where I would lose drivability.

Want to share your ideas...?

I think I am going this route for coilovers. I was thinking of putting spherical bearings in the 4 link. Thing I am at a loss for is rear diff and brakes. Although I have a set of rebuilt TII calipers I could use.

My front suspension on my 2 is on and it sits to high (2 1/2 in to high), I have front 82 rx7 struts , coil overs and re speed ( garbage ) camber plates witch I am going to have to re design and 275 lb springs ( because I have a 13b turbo car ) . does anyone know of a shorter front strut ? I am using re speed tubular control arms with miata ball joints and I am pretty pleased with those .
