OK. Searched around a bit and came up with zero. And since I only care about the FD in this caseI put it in here instead of the suspension section.

Anyway, it seems that my upper arm on the pass. side is just slightly bent from a wreck I had last year. Initially I had a pretty bad shake at speeds, but has since gone down after my coil over upgrade. It's still there and want to get rid of it alltogether. And since I want to replace that, I might as well look into an aftermarket option. I've searched around a bit on the 'net and came up with...you guessed it, zero.

Who if anyone makes an upgrade to the control arms and what's their link?

Is anyone using those and is it worth it? Probably not is the answer I'm guessing I'm going to get, but I'm looking at the value it will have at the track, if any.


Thanks all in advance...

 

I'm yet to see an upgrade. A control arm is a control arm, upgrading one the most I could see you gaining from it is maybe lighter weight. Just replace it with a used or new OEM piece.

 

Look on the web for "tubular control arms" and you'll find a few small shops that make them for RX-7's. It's an upgrade, mind you, so it ain't gonna be cheap.

 

I don't know, it seems Mazda did a pretty damn good job with the control arms. I believe the lower arm is forged and the upper arm is squeeze-cast (like the wheels). Hard to improve on that weight/strength balance.
