I have been working with a chassis shop to develop this bolt-in manual rack and pinion for the FD3S, and its ready to go! After having no luck trying to find a good manual rack option, then going with a dry power rack I wanted something better.
These are available in a 20:1 ratio for drag guys or a 14:1 quick ratio for the road race/scca guys. These have more travel than the factory rack so you will gain a slightly tighter turning radius as well. These are a 100% bolt in replacement rack and work with the factory outer tie rod ends!
I will have these ready to ship in about 4 weeks. I have to disassemble the racks from the factory and have the tie rods cut down and rethreaded for the FD outer tie rod. I had 10 mounts made up, so once they are gone I am not sure when I will do another run.
One great feature is the mount setup, this will allow you to clock the rack so that you can actually gain clearance for different engine combinations.
I am taking deposits on the first 10 racks here:
