Since my car is already classed in E-mod for SCCA I have no problems converting my rear springs to coil-over units. I've heard someone sells them but they aren't SCCA legal for most classes. Because of this, I haven't been able to find a company that makes them. Does anyone know where to get a set? My roomate just put a conversion kit on his Saleen mustang and I was really impressed. Now I think it's time for me to get a set.

 

i know that g-force engineering will make you a set. but then are definatly not bolt in like the fronts.

 

I've also heard ISC racing makes 'em

941-324-2742

 

ground control also has a rear coil over set up i believe.

I have their rear threaded spring adjusters on my 1st gen. Makes it real easy to lower the car. Not a coil-over but next closest thing

 

oh hell yeah!

Cheap too

what spring rates do you run?

 

Ground control sells all the parts that are required to converty to a rear coil over, but as it says on the site, it is going to take alot of imagination, and fabrication to make it work.

 

You think harder or easier than stuffing a V8 into an FB? Personally it would have to be pretty F'ed up in order to scare me. I'm already planning a custom Tri-link, TII front rotors, a Ford 9" rear, and probably some more projects of a custom nature. Personally rear coil-overs sound right up my alley. But honestly it isn't really that worth it to me if it's going to be a huge PITA.

 

I dunno, call Ground control, they probobly have the best idea of how big a bitch it will be.
I decided not to do it, simply because I dont need to adjust my rear ride hight. it takes about 5 mins per side to swap out springs of different rates.

If it wound up not being that hard to do though, I might give it a second thought.

 

its a big fat bitch (oversized). A v8 is not that hard, there are parts for it and sold in many places/ kits. the rear end chasis is not made to handel the weight in the curent location of the shocks. its not hard to make the shocks coil over its just not doable to install them. if you still wanted to do this you need to design some braces, suport plates and find out what where and how. probably easer to install that mx5 rear assy with a t2 rear pumpkin. do you have access to a automotive structual computer program and the rx7 spects for input? or go the easier way and install tubs, rear frame members, roll bar, and new shock mounts from summit or jegs for a custom suspension for that ford rear end. the t2 front brake thing has been done a number of differant ways easiest is to find out what car has the right size retaing ring to mount on the 84-85 rx7 front spindal to use the t2 stock hub assy complete and make a braket to fit the t2 calipers in the correct position and share that info with every one else. unlike some that have done this already.
