How To Convert a 1970-81 Camaro/Firebird Sub-Frame to Full Coilover

How To Convert a 1970-81 Camaro or Firebird Sub-Frame to Full Coilover
 

Doug from Global West Suspension shows you how to modify your 2nd generation F-Body Camaro/Firebird sub-frame for converting over to a full coilover application using kit COF-781.

If you are planning on lowering your car and running big tires for pro-touring or just achieving the desired look, extended travel front end kits are something you should be looking at.

A full coilover system provides additional ride height adjustment and a wide selection of spring rates…

The Global West Suspension Advantage

As coilover suspension grows in popularity and ride heights get lower, suspension travel is becoming more limited. Dropped spindles lower the car down but reduce the amount of back space you can use on the rim. This makes for less tire on the front end, unless you step up to a 18 inch or larger rim.

Why is the dropped spindle an issue?

The inside of the rim hits the tie rod end because a dropped spindle raises the spindle pin up in the spindle, the steering knuckle arm that the tie rod attaches to stays in the stock location.

You can, and many do, use conventional coilover shocks that plug into the stock frame using a conical wound spring; however, you will run out of travel if you get into a 2 inch drop scenario and drive aggressively. You need more travel! That is why COF-781 was designed; it allows for extended travel. The upper shock mount is raised above the frame.

Note:The stock upper control arm can not be used. The arm will hit the raised shock brackets. Most tubular upper control arms will work. The Global West upper G-Plus control arm kit CTA-71a.

Recommendations: Global West does not recommend using the stock lower a-arm. You need a purpose built lower arm for this application. We recommend using coilover lower control arm CTA-71H.

Any coilover shock can be used. We supply two coilover shocks brands, QA-1 and Penske. Global West offers QA-1 shocks (single or double adjustable) and Penske (single, double or triple).
