Thank you. You have rated this product.

Finally...a solution for all you owners of JIC or OHLINS or similar coilovers on RX8 or NC generation Miata which use the high clearance springs in the rear with the factory aluminum top hats. This Delrin Top Perch allows you to use shorter linear race coilover springs of your choice.

We use these to run Swift Coilover springs in the rear on our Ohlins (70mm X 152mm) (Note that owners of JIC and OHLINS coilovers need 70mm / 2.5" diameter springs).

These will also work with 2.5" / 65mm diameter springs.

Picture shows one Delrin Upper Spring Perch in action between the spring and the Factory aluminum top hat and another Delrin Top Perch is in bottom left of picture (bottom right item is for helper springs and NOT included). NOT FOR USE IN COILOVER CONVERSIONS, must be a REAL COILOVER wherein you can have some pre-load on springs.

Price is PER CONVERTER so order two if you want two! Yes, we can also get the Swift Coilover springs of your choice, we have many listed in the coilover section but if you don't see what you need just email us.

INSTALL NOTES, you need about 3/8th spacer to get the shock more straight so it won't rub the Delrin adapter and 5mm longer bolt (40mm instead of stock 35mm bolt). Depending on the coilover you may also need to look at the sleeve that slides into the bottom of the shock (on our Ohlins the provided sleeve is sufficient). We offer those bolts and spacers as a separate item in our store.

NOTE you likely MUST use shorter springs in 70mm diameter with this item like we did and noted above. Most use either 6 inch or 7 inch rear springs, depending on the coilover and how low they want to set their MX5. Note we cannot tell you the perfect spring length because there are too many variations in coilover design (some bottom couplers are long, some are short, etc). Thus, be prepared to take your own measurements and figure it out, perhaps some trial and error on spring lengths, or do NOT order this item.

Just wanted to thank you guys for the great stuff and great work done on my MX5 club yesterday. I could feel the difference in sound and performance right away! It drives and corners awesome now. Can't wait to tell my friends about you guys. I'll be keeping an eye on your web site for other goodies and events as well. Can't wait to try my new suspension out on a auto cross. Will definitely be trying it on some twisty roads this weekend. Just can't wipe that smile off my face when driving this car. Thanks again guys!
