I installed an FE2 bar on my RL last week. REMARKABLE change. But, I am sure it is too soft. The ass end became real "happy". I raced Sunday and attended an Evolution Challenge class Monday. The front end is really planted, even with a bit more body sway. The back end has become quite loose. I raised the front pressures, lowered the back, and it helped. All this said, I will probably put the FE3 bar back on until I can get some Konis.
Can the FE2 or FE3 bar be modded to allow adjustment? The flat area where the connecting rod bolts up is fairly short. The bar itself is too thick for the through bolt to be effective as it will not reach through that far to be nutted. Aftermarket links on the FE2 may be the answer there. But then there are SCCA legality as well as safety issues. I doubt the bar would fail and if it did then the handling would go to hell as opposed to a control arm failing. On the FE3 bar one could play with welding on an extension but heat can do bad things to steel.
BTW, Memphis, I am curious why you want to go stiffer.
