Thank you. You have rated this product.

Finally...a solution for all you owners of JIC or OHLINS or other REAL coilovers on RX8 which use the high clearance springs in the rear with the factory aluminum top hats (note these ONLY work on the style of aluminum factory hat you see here, not the black steel version factory offered at one point, and NOT for coilover conversions). This Delrin Top Perch allows you to use the shorter coilover race springs (65mm and 70mm diameter depending on your coilover).

We used these in our Project to run Swift Coilover springs in the rear (70mm X 152mm) (Note that owners of JIC and OHLINS coilovers may need 70mm diameter). 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 (the bottom right delrin item is a converter used to add 2.25 helper springs).

Price is PER CONVERTER so order two if you want two! NOT FOR USE IN COILOVER CONVERSIONS, must be a REAL COILOVER wherein you can have some constant preload on springs. Yes, we can also get the Swift Coilover springs of your choice...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). 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).

Note we cannot tell you the perfect spring length you will need 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. Most will need 6 or 7 inch length springs in 70mm diameter, assume some trial and error on spring lengths may be involved to get the results you seek, or do NOT order this item. That means this item is for the EXPERIENCED modders out there, if you understand coilover design and assembly you will appreciate this item, but know your limitations and understand that average Joes should expect to hire a good motorsports mechanic to install these.
