Billet aluminum rear suspension knuckles for the SW20 MR2!
Benefits and Features:
-Saves 5.5lb per corner, a 28% weight reduction on the knuckle / hub assembly.
-Improved suspension geometry. Strut angle is increased for a slightly better camber curve, and bump steer can be fine tuned much easier than with stock knuckles.
-Easier wheel bearing changes due to the bolt on bearing and hub assembly.
-Improved suspension travel compared to stock knuckles or stock knuckles plus my geometry kit.
-Alignment aid. Threaded hole in the top of the knuckle tab allows an M8 screw to be installed to reference a camber setting before taking the suspension apart, enabling it to be re-assembled to the same camber setting easily.
-Front hubs from a 2006-2012 Toyota Rav4. Not included. Rav4 V6 hubs match the E153 axle spline, Rav4 4-cylinder hubs match the S54 axle spline.
-Roll center adjuster and tie rod from my suspension geometry kit OR control arms with an inverted ball joint and ~1.25 in of roll center adjustment built into the control arm. Matching front geometry correction highly recommended.
If you already have my geometry kit you will need:
-A new pair of rod ends for the outer ends of the tie rods (5/8" bore instead of 1/2" bore). $40
-If you have the short tie rod version of the geometry kit you will need a 1" longer tie rod tube (11" instead of 10"). $30
-If you have the long tie rod version of the geometry kit purchased after April 2021 you will need a 1" longer tie rod tube (15" instead of 14"). $30
-The options below represent the most common combinations of required parts. Please contact me if you have any questions about what pieces may be needed to complete the installation.
The included bump steer spacers should be close enough for most users, but if you wish to fine tune a little you will need some additional spacers. This kit includes 2 each of .030", .060", .100", and .200" aluminum bump steer spacers. You will need to remove the spring, and jack the suspension through it's range of motion using a bump steer gauge to properly adjust bump steer.
