Strut Modification and Services
For Porsche 911, 912, 930
Services Available for Boge, Bilstein and Koni Struts
Strut Reconditioning
We inspect the struts for bending, rust or other damange. We will media blast the entire strut to remove any rust, grime and old paint. Strut is then modified to desired specification and receives a fresh coat of paint.
Raise Spindle
Send your existing Boge, Bilstein, or Koni struts to us for spindle height modification. ’69-’89 type struts only.
Raised spindles are the right way to lower your car. They restore lost suspension travel, improve the camber curve and roll center geometry.
Note that raised spindle should always use tie rod end bump steer kit to correct the steering knuckle height change.
Spindle Height – Choose from standard raised spindle heights:
- +19mm / 15 inch wheels
- +30mm / 16 inch wheels
- +40mm / 17 inch wheels
- Rally height -70mm
- Custom height available
- Boge and Koni can be raised up to 19mm max.
Brake Support Line Relocation
In order to raise spindles, brake lines either need to be relocated or removed. This service includes bracket relocation, however if you’re planning on installing coilover sleeve conversion kit, the brackets need to be removed. Bolt-on brake line support is available as well.
Linear Bearing Replacement

Race Bump-Steer Kit Installation
Send in your struts to add bump steer kit. Our racing bump steer kit comes with a lower steering knuckle that requires welding. This is a popular option for people raising their spindles. Available also a bolt-on bump steer kit which requires no welding.
Gusset Installation
Add gussets to reinforce the spindle. Commonly done with spindle height modification service. Gussets are welded on each side of the spindle.
