I tried SBv2 arms!!
They completely change the feel of the car. Its much more planted, does not have the tendancy to roll on it's top on high grip surfaces, and lost it's loose rear end on low traction surfaces; all while increasing steering throw and stiffness (reducing slop). Try them, they work great.
The only problem is that the front bones aren't long enough. I need to get something about 4mm longer to have the pins in their original location.
Any suggestions?
