The HLS spring perch is a sealed unit that takes the place of the tender spring. As an experiment, we will be using the HLS system to allow us to rake the car so we can use it as a DRS type system on the track. Since we will be using a full flat bottom and rear diffuser on the car, the rake can make a big difference in the downforce the body can create. More to come later.
For swaybars, we choose Tarett Engineering’s adjustable racing sway bars. The front sway bar is a lightweight part that is tubular like the OEM bar. It is 26.8mm in diameter, up from the stock 24mm bar. The front bar is 5-way adjustable. The rear bar is also a hollow piece that is 19.1mm vs the stock 18.5mm in diameter. The rear bar is 4-way adjustable.
We also used Tarett Engineerings end links. The end links are adjustable in length which will help to take the bind out of the sway bars when corner weighting the car. The end links are very stiff, made out of billet aluminum with high-quality spherical bearings for the ends. There is no flex or give here.
The mounting bracket for the front Tarett bar is made for the Tarett struts which are made by JRZ. The will not work with our KW parts so we are going to have to do some minor fabrication to get them to use the stock sway bar end link mounting position.
For lower control arms, we opted to use Tarett Engineerings very trick parts. They are machined from aircraft aluminum billet and are completely adjustable.
