Re: RX-7 Rear Suspension Project
Thanks Alvin. Did you guys happen to make/keep any link and heim dimensional measurements/drawings for the final fitment? ( As in record any?)

Re: RX-7 Rear Suspension Project
Unfortunately none I can remember. This was ~10 years ago! I plan on removing the assembly to clean things up and make changes if necessary. I can definitely take measurements then.

Re: RX-7 Rear Suspension Project
Forgot to add these pictures with the car on a lift for new tires
Year 12 with the RX-7 rear axle setup!
~57,000 miles on it.



Lots of road grime/dust but still holding up.

Re: RX-7 Rear Suspension Project
That is such a neat and effective suspension set up, I wonder if they could be sold as a kit. Obviously some cutting and welding to install, but it looks like it was made for it.

Re: RX-7 Rear Suspension Project
So, why is inside of your right rear wheel so much cleaner than the left? 
That suspension is quite the trick and removing the leaf springs really cleans up the look. I love it!
