It really depends on your track. I'm running the light blue/orange springs plus 2.8/2.6 sway bars right now. We have some really fast sweepers and some off camber stuff on a sugared track. I'm running bald M2 Blockades. I tried running a new set of Medium Enduros and the car traction rolled all over the place. I still have a 3.0 sway bar in my box that I've been wanting to try. When the track was dry and dusty I had Tekno green/pink and stock sway bars on the car.
