S13 Suspension On FB RX7 Part 2 ( Rear suspension install)

So I ended up not going with ,exactly, what I mentioned in the first post. I was able to get my hands on a set of HKS Hiper D S13 Coilovers.


They were used but I scored them for $300 , little dirty but that's not a big deal.
I set out to tackle the rear coilovers first, so I drew up some stuff and ripped out a prototype to change my tophats so I wouldn't have to mess with cutting the inner fender well.

I eventually machined some tophats from aluminum and bought some energy suspension bushings for swaybar end links as they are the same size as the coilover stud


I did score some smaller springs from a local race shop for free. Higher spring rates but it doesn't have the helper coils.




After facebook friend had sent me this shot of his setup on some nonadjustables. I think this is the route I'm ending up going.



So after mocking it up this is what I had, I decided not to go with the shorter springs I also decided that I want gunna use my tophats because I needed a stud extention and would not be able to adjust them any more as the adjustment screw was at the top. 




My Facebook friend was also kind enough to send me this pic of his car and the trimming needed.

So now I had heard that if you trim the inner fender well that full size coilovers would fit, was well as slide into the lower mounts with a tad of trimming.


After starting to mock it all up I decided it was worth trimming the inner fender.

Coilover slipped right in the top perfectly , the bottom however the bolts where much smaller than the s13 mounts , so I pressed out the factory dampener's bushings and machined them down and pressed them into the coilovers so I could reuse my factory bolts.

With that done the rear is pretty much done.

See how i did the front
