Fully adjustable Suspension mounts vertically mounted Part 1: When racing in a large variety of conditions, we understood the need to have the suspension brackets vertically adjustable so you can fine tune your GT. These suspension brackets are made from 7075-T6 aluminum alloy. Although RC shims are no longer in the kit they can be purchased separately to even further adjust the roll center. You can adjust the front kick up, front anti-dive as well as the rear anti-squat or pro-squat, depending on what you need. Without any doubts, we had to carry this over to the new SRX8GT ‘23 model Complete set of Inserts for Suspension Adjustment Part 2: The 7075-T6 brackets also allow you to fully adjust the front kick-up from0,0.5,1,1.5 and 2 degree in increments of 0.5degree. The rear anti-squat is no different as you can adjust that from 1,1.5,2,2.5,3 degrees, and the rear toe-in adjustment can be made, 2,2.5,2.75,3,3.25,3.5 and 4 degrees using the inserts provided in the kit. With so many inserts available to you as well as the ability to purchase the RC shims, there is absolutely no way, you will be limited in your quest to dominate your local track.
