ok, so i have the Fc front subframe swap done, and im looking into buying aftermarket coilovers (kyb suspension and edelbrock adj. coilover springs, so now that im buying these parts i was wondering wouldnt it just be easier to buy the complete fc set for front and back of both,
and i know what your going to say about the rear coilovers, its for a irs car, and this is solid axle yes im aware, but i know i can fabricate a different mounting point for it if need be, my question is more about spring rates and whether the fc springs would be too stiff for a fb,
i have a welded in roll cage aswell that runs right beside the top of the suspension mounts so i dont have to worry about a strong upper mounting point

any tips or comments welcome,
i am seriosely considereing this
if its any consellation im planning on doing a tri link, and panhard bar setup at the same time as the rear suspension... if that makes a difference

 

NOT RX-7. but this show you, you can swap live AXLE suspension to IRS

There's a guy that's swapping a Miata IRS into an FB (with V8 power). It's in the first gen section, try searching for Miata in there, it should be easy to spot.

 

no im just talking about the rear suspension, and coil over kit, not the full irs or anything like that

 

An FB is a solid axle, an FC is IRS, so the only "rear suspension" that could possibly be used are the shocks/springs... so, is that what you're talking about? Using a single coilover in the rear instead of the spring/shock setup?

 

There is no need to cross post on this.
