The RR i raised the top bar to 5" and the lower at standard 4.5", the car laid over bad on the RR. Same bar angles, i set it back to 4.5" on the upper bar and the attitude was better. May be a great adjustment when its super slow and slick.
LR, lower bar to 5.5" on a zero index deal, actually it indexes a little so... Anyway, same angles on the bar, just lowered it on both ends. It makes a lot of drive, and really promotes the hike. We're running around 300lbs of droop load.
Once i moved the LR bar, car really made the drive we needed. I would be careful on a SLM, track would have to be somewhat slicked off or you might just shove the nose all over the track. This has been one of the biggest impacts to the car, really changed how the car drove.
Also one of the biggest changes i have seen is a 3" bar length split on the RR, really deadens the drive and makes it lay over and calm. The indexing change really helped.
Hope the helps. We race on dry slick pretty much all the time, Hot Laps you get some wet but thats about it.
Also this was all with the same springs, shocks and stagger.
