How To - 914 Adjustable Rear Coil Overs, Specifically for Bilstein shocks Options

[tomeric914]

I was looking for details on the interwebs on coil overs with helper springs in particular for the Porsche 914 and found not much at all. There was something pretty close on an Audi forum, but not close enough. I was looking for a cost effective coil over setup that works and found http://shop.a1racing.com who had everything I needed at a decent price.

Zero rate helper spring keep the main spring pressed against its perches when jacking up the vehicle or any time the suspension is fully extended. These helpers are usually needed when running a spring rate higher than 150 pounds (in a 914), otherwise the back end of the car will be too high.

Below is a parts list, visual parts list, and video of how it all goes together. The part numbers listed are specific to A-1 Racing's website.

This is one of many ways to get to an easily adjustable suspension setup. Main spring rate will depend on your driving style and intentions for your car.

Note that part numbers BRP597 and 12460 have been modified slightly to allow for full compression of the helper spring. If not modified, the floater will contact the adjusting nut before the helper spring is fully compressed causing all of the force from the main spring to press against the thin aluminum coupler. The coupler will fail.

The floater / coupler does go on the bottom. Otherwise, the helper and main spring will have no lateral support.

As with any modification, proceed with caution. If you don't know what you're doing, STOP and find someone who does. (IMG:style_emoticons/default/bye1.gif)

Hello and good day
I'm interested in the Coil Cover parts.

Is there also a ADJUSTING NUT for series springs?
