AAF Porsche GT3/GT4-style Alignment Shim Kit

Alignment Shims Set: (2 of each size): 0.080″ (2mm) , 0.125″ (3.2mm) , 0.25″ (6.4mm)

What vehicles do these fit?

All water-cooled Porsches fitted with GT3-style (two piece) lower control arms, front and rear. 986, 987, 996, 997, and front of 991 may use these arms. For 991 rear shims, see our other kit (116259).

What are Alignment Shims?

Installation of these corrective pieces are relatively straightforward and would be considered “easy” were it not for one big detail: you need access to an alignment rack or machine to install them properly. If your car needs an alignment service, call us 509-924-7006 and schedule an appointment.

How do They Work?

They are designed to space lower control arms out to correct camber and toe measurements that are out of specification.

How are Our Shims Made?

Our shims were designed by our in house engineer to correct toe and camber of Porsches we have aligned. We use the best aluminum to create these.
