I'm on RCE yellows, stock shocks/sways - camber bolts and plates up front with SPC LCA's out back to get to -3.5F/-2.4R with 0F / 1/16in R toe. SX2 (200TW) tires, rest stock.

Tires are now wearing relatively uniformly across the tire with this camber setup (MPSS shoulder's absolutely got killed at very similar camber). No consistent reading on tire pyro after I drive off track and back to the pits (cools off a lot) - but nothing that looks bad either -- so I can mostly only go by wear for now...

Pictures from the track show a lot of roll ... e.g. http://www.hart-photography.com/phot...#image=4111227 -- inside front tire contact patch looks to be at 1/3 width or less in lots of the turns.

Will stiffer sway bars improve my cornering traction significantly, or just a little? I think the real answer would be stiffer springs, but that means shocks too so I'm into coilover money... not wanting to go there yet...

I like the car as is and am having fun and tire wear with the SX2's is good across the tire - getting ~10 track days out of a set with proper rotation... But, I kind of like to tinker, and if a (relatively) cheap set of sway bars would improve things a fair amount I am willing to try them...

Also - would stiffer sways mean I'd likely need to (get to) dial out some of the static camber?

Thanks !

If you like the way the car is handling now, I'd be hesitant to change anything! That body roll might not be holding you back all that much. Another season of building experience with a car that does what you want it to do and is reliable/consistent is valuable.

Buuuutt...I like to tinker too. Swaybars would reduce body roll and you may be able to reduce your negative camber slightly. Keep in mind most front + rear swaybar sets will increase front roll resistance more than rear due to the motion ratio of the swaybars. So you may have to fiddle with the alignment to get things just the way you want them.
