1x Pair of knuckles with ackerman washers

Bolt-on Super Angle steering knuckles for FRS, BRZ, GT86, GR86. OEM quality cast steel and CNC machined for great strength and symmetry.
Features 45mm Roll Center correction, 6 way ackerman Adjustment, 60 degrees Max Steering Angle when combined with the full front parts set, or 46 degrees of angle by themselves (stock angle is 35*).
Features Two caliper mounting options built in:
1.) OEM caliper, OEM rotor, or
2.) Z32 Alum 4 piston caliper (we sell a 100% new loaded pair for $315) with 05-09 Subaru Legacy GT rotors. 12.5mm reduced coilover mounting depth gives leans the knuckle in for -1.5 degree additional camber ability and improves KPI. Comes with 24pcs ackerman plates (6 settings X 4 pieces each setting).
To get the most steering angle you need to combine this with our front parts set less the knuckle. If using these knuckles with stock arms, use part # OTRLB outer tie rods because OEM outer tie rods are not compatible.
Overall angle clearance depends on wheel and tire size and offset. **17" inner wheel barrels vary in shape which could cause interference with lower arms and outer tie rods now that there is roll center correction.
Grinding of the lower arm and flipping the outer tie rod bolts to be head down could resolve this clearance issue.
