Is anyone getting away with the hollow gendron bar?
I have 650/600 f/r spring rates and the hollow bar on full stiff and it feels like a lot of body roll. I'm considering going back to the solid bar... but that sucker is heavy.

I am running a .25 hollow with great results.
Static RC height isn't all that much affected by lowering the car. When I modeled the geometry I found that I'd have to raise the car over 2" to get 1/2" RC change. That just isn't anything to worry about. It's generally low height is how ever a good reason to run big sway bars on this car.

The springs are a bit on the soft side if you want no body roll. However, body roll does not mean bad handling. What you want and what your car does are different in this situation, and if your car is easy to drive and is well balanced, then I would not change anything. Don't change your car for change sake.
The desire to change was to try to find a way to get the rear bar off. As others had reported, there is a pretty clear improvement on when you can put power down (spent the morning of the TnT with no rear bar), but obviously the roll increases.
The solution would be to stop DDing this car so I can justify higher spring rates
It looks like I'm going to run helper springs in the rear, and I'm wondering if anyone has tried tender springs instead of just helper springs, to make sure the rear tires stay planted? Is rear inside wheel lift a non-issue with stiffer springs (ie STR vs Stock)?
Should I just run helper springs and forget about it?

With near stock ride heights, my Hyperco helpers and 7" springs have roughly a half inch of extension at full droop. They will get more necessary as I lower it.
The reason for helpers isn't just pressing the rear tire down but also so your rear spring stays seated and doesn't mash up your perch.

Helper springs are only for keeping the spring seated. Tender springs provide some spring rate.
Tender springs could be 100 lbs or so, just enought to make sure the rear tire is planted if the spring extends to free length (ie no force).
Is anyone anywhere near unseating the rear spring? If not, I think that answers my question.
