If you want to be able to fit bigger front brakes I have two sets of siR front knuckles - one with calipers and one without, so people who need an upgrade for front brakes as well can keep it balanced (since the fronts do most of the braking anyway):
************************************************** **************
siR knuckle set #1:
Left - has stampings on the back (LH3-A) and front (9GJ)
Right - has stampings on the back (RH#-A) and front (1CK)
The caliper mounting bolt holes are 5.5" from center to center.
There are no abs sensor mounting points on them.
They measure 16" from the top of the lower ball joint to the top of the knuckle where it mounts to the upper ball joint @ the highest point:
They measure 11.5" from the highest point to the upper caliper mounting bolt hole center:
They measure 16 & 7/8" from the highest point to the lower caliper mounting bolt hole center:
They measure 14 & 1/8" from the highest point to the tie rod mounting hole center:
siR knuckle set #2:
Left - has stampings on the back (LH3-A) and front (9G4)
Right - has stampings on the back (RH#-A) and front (9G6)
The rest of the measurements are identical to set #1.
************************************************** **************
$150 for the knuckles without calipers.
$200 for the knuckles with calipers.
