Project STurdteen: Installing Parts Shop Max Suspension


After that, we installed the rear upper control arms.  The rear upper arms adjust camber.  The upper arm and the traction rod are both equipped with spherical bearings. 

Then we went onto installing the PSM rear low friction spherical equipped bearing toe rods, which have been specifically built to be used with the Limit Break rear knuckles.

Here are all the arms in the place!  Now we are ready for the knuckles. 

Next, we piece it all together by placing the rear drop knuckle and hub combo in place. 

We make sure to bolt everything up. All of the arms are installed in the designated areas of the knuckle. 
We tighten everything up!  We set the limit break bracket in the middle setting, which gives close to a neutral toe curve.  We chose this initially as our SR20DET is a relatively low powered engine and we don't want to bog it down with too much rear grip. 


  1. It would be amazing if mike posted an article about aligning this specific setup as it is a common combination for a lot of grassroots drift cars.

    1. What I would set it at for a baseline for a low powered SR20DET grassroots car is around 5 degrees negative camber in the front with 5-6 degrees positive caster and 1/8″ toe out with the roll center corrected and bump steer adjusted to zero. In the rear, I would set to toe curve adjuster to neutral toe (no toe in gain), zero rear camber and zero to 1/8″ toe in. If the car had higher power, I would toe the rear in 1/8″ and possibly set the toe curve to gain toe in under compression a little. I would adjust the traction rods longer for a flatter toe curve. Roll center should be corrected by the rear knuckles. There you go!

      1. Thank you Mike! I have one more question. What is your opinion on lowering the front mounting point of the rlca to correct anti squat on s13’s?

        Thank you so much for sharing your vast knowledge with us grassroots guys!!

        1. For Pro cars, I lower the front 1″ and raise the rear an inch. This works well but for a grassroots car, you risk bogging down the motor. I would say you need at least 400 hp to exploit this. For close to stock DET’s, for example, that struggle to drift 3rd, don’t bother.
