Project FD RX7 Restomod: Part 21 – Suspension Refresh with SuperPro USA polyurethane bushings.

FD RX-7 toe linksWe disassembled the steel toe links to prepare them to be powder coated to match the subframe.

FD RX-7 toe link and AC compressor hardwareWe removed the toe link hardware and sent them off to be zinc plated, along with our AC Compressor bolts and miscellaneous bolts that could look a little better.

FD RX-7 Powder Coated Toe LinksThe toe links looked significantly better after powder coating.

FD RX-7 powder coated toe links and SuperPro USA polyurethane bushingsWe reassembled the toe links with new SuperPro USA polyurethane bushings and the black zinc plated hardware.  Now the toe links look amazing and will hold up to the elements.

FD RX-7 rear suspension SuperPro Bushings vapor blastedWhile the suspension was off, we replaced the wheel studs with M12 x 1.50” extended ARP studs (PN: 100-7713) which are 3.25” long with a knurl diameter of 0.509”, which is ideal for the FD RX-7.  This will enable us to have a lot of flexibility with wheel sizes, offsets, and wheel spacers when testing various setups.

  1. What is the overall goal for this car, Billy? You are putting so much money into it that you might never drive it to avoid scratches! Everything is top notch and I enjoy reading every installment.

    1. The car is being built to be driven and to share the rotary platform to a new group of people and to demonstrate that with proper engineering, they can be reliable and extremely high performers. The car will be tracked and taken to many events. This is not going to be a show car or garage queen.

    2. It is done as a well balanced reliable car and this and what we did to our STI are examples of what it takes to do it right.
