Starting 2020 with some goodies, SPL front LCA and Cusco front sway bar.
The SPL arms allow for camber adjustments in the front which is what I need for track right now. Also after few trackdays I noticed how soft the suspension is, even with H&R springs, so I went with stiffer front sway bars to try and fix that.
Installing SPL arms was so easy and straight forward however I wasn't comfortable with how close the sway bar was to the arms. Its clear that installing any adjustable sway bar will not be possible.
I ran into two problems after the install of the parts. First was after increasing front camber to 3.1 degrees. The car gained around 1.5 degree of caster in the process and the ride height dropped a bit. So I went with 2.5 degree to try and get some of the caster back. I have ordered SPL adjustable caster bushings so I will be increasing camber if needed again.
Second problem was getting the chassis error codes.
After some research I found out that usually these issues are coming from the headlight level sensor connected to the arms.
Stock level sensor normal position
SPL level sensor normal position
Basically the bracket supplied with SPL arms is designed for Supras with normal ride height, and the headlight level arm should be at around 90 degree angle to work properly.
So I drilled another hole to compensate for the extra drop from H&R springs
There is no more codes so far and the new offset for the drilled hole will be sent to SPL to include it in future brackets.
Now the car is ready for more track action!
