This wide chassis likes to play dirty with the carpet so I have my ride height up a tad @ 5.5mm
silver front roll bar and black rear.
Roll center I have zero shims on the a-arms and 2mm on the upper Camber link in the front which is on the most inside hole and in the rear I have .5mm shim on the most inside. and inside hole on the hub.
3 degree rear toe to keep the rear in check. Anything less and the rear wants to be first.
Shocks are second from the outside on the tower and outside on the arms
All of the internal bracing is gone.
Camber f/r is 1.5/2 degrees running 4 degree caster in the front
Sweep 32 degree tires with Paragon ground effects (Black can) Full rears 1/2 fronts
Any Suggestions TC4 gurus
Thanks
First thing I would change is to take away some camber. Can you tell if the vehicle is picking up the front or rear first? If so, reduce camber by 0.5 deg at that end, and perhaps all around. I would actually try keeping the softer springs you have and reduce your oil weight to 40/35 or 35/30. Heavier oil will slow things down but will also put more force into the tires in bump. Laying the shocks down a hole or two will soften the rates but also make them more progressive, and this tends to help as well.
