This setup is proving to be good when traction is low to medium grip on super soft tires. The rear buggy hubs helps tame the roll of the vehicle and I'm liking the overall balance it gives the truck on tighter low speed tracks. Be warned these may not work well on high speed and higher traction tracks as it changes the truck's roll centers a bit.

If you lack a little steering reduce the rear toe in .5 increments until it balances out and try the purple front spring.
