Strut Modification 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.
