Feeling left out and suffering from a bit of peer pressure I started looking into this today. Looks like the SwayAway 3/4" bar is one if the cheapest out there but it doesn't come with hardware (although afaik, this could be a cached webpage from 10 years ago).
I found references to a SwayAway camber compensator, too, but found no evidence of it in their website. I guess I'll gave to use the EMPI one.
Based on how my Spider handles now, and all the reports of sway bars, camber compensators and Vredestein Sportracs, I can't even imagine how it's going to handle next summer.
