Fitting 08-10 Cobalt SS Brembo calipers to you og9-5 and ng9-3 is a great upgrade. …But and adaptor kit is needed!
Sold in pairs. US DOMESTIC SHIPPING INCLUDED
This kit included specially machined bolts to adapt from m14 holes in the spindle to the m12 hardware needed for the Cobalt calipers.
ALSO! The calipers are not centered over the rotor when using the modified Cobalt rotors. Because of that, a shim in needed between the wheel bearing and the spindle. This prevents brake pad drag or rotor interference with the caliper.
315mm Rotor Notes:
The 315mm Cobalt SS rotors have been a common option for many older or base model Saab’s for use with the Brembo calipers from the Cobalt SS.
These rotors do require modifying the center bore fro 65mm to 70.1mm. This is something most machine shops can handle, and, some vendors offer these premodified.
These Cobalt rotors are preferred over the Saab ng9-3 v6 314mm rotors because the Saab rotors are too wide for the caliper. Using the Saab rotors would require having them narrowed from 28mm wide down to 26mm wide and discarded at 24mm wide.
Additionally, the steering knuckle and Cobalt Brembo caliper both need clearancing because the mounting ‘ears’ interfere. A cut template is included to make this easier for you.
