Bilstein strut

Bilstein RSR strut

We have Bilstein struts in a choice of regular and RSR types.

Regular Bilstein struts are as-equipped on 911 turbos and were optional on 72-89 normally aspirated 911s.  These come complete with a Bilstein HD insert.

RSR struts are developed for race cars.  They have a threaded body that allows optional installation of coil over springs (can be used with coils or torsion bars).  They have a spindle raised 19mm to improve geometry and suspension travel on lowered cars.   They have a stronger, gusseted spindle for racing.   And they include an insert with special RSR valving.

In general we recommend custom valving for RSR inserts.   We can custom match the valving to your spring / torsion bars.

Raised Spindles

We modify regular or RSR struts to raise the spindles.    This service can be performed on new struts you purchase from us, or your existing Bilstein struts.

Raised spindles offer a couple of advantages.    For cars that have been lowered, raised spindles restore suspension travel.  This reduces the propensity of lowered cars to bottom out.   Raised spindle height also improves geometry with a superior camber curve that is better matched to modern tires, thus improving grip.

The amount the spindle can / should be raised depends on the wheel diameter.   Regular Bilstein struts are designed to work with 14 inch wheels, this forced a severely limited spindle height.   With modern wheels, we can improve on that original design.

- 15 inch wheels can use 17mm raised spindles

- 15 inch wheels can use 19mm with wheel spacers or clearancing of ball joint hardware

- 16 inch wheels can use 29mm raised spindles

- 17 inch wheels can use 40mm raised spindles  

Note that raised spindles require using an Adjustable Bump Steer kit.    

Gusseted Spindles 

We can modify regular struts to gusset the spindles.  Gussets add strength to the spindle for racing applications and are similar to those equipped on RSR struts.

Custom Valving 

Match your shocks to your torsion bars or springs.   Custom valving available for Bilstein shocks and struts to Elephant Racing specifications.
