Yeah they are using the S13 fronts but the neat thing is the way they have mounted the rear spring. It's still a spring+shock setup but they've produced neat little cups for the rear teardrop shape mounts. That should mean little to no fabrication on the rear to make stuff fit. The shock does look like a S13/14 replacement with the spring and collar removed but a production off the shelf product with manufacturer warranty would be great IMO. Saves the less talented among us, people like me

, a load of hassle
