Nope, with a higher rollcenter, the car is more aggressive and will traction roll more abrupt.
With a lower roll center, the car will roll in the suspension. You feel the moment much better when it's going to flip over and the flip over will happen later.
In Belgium and Holland, most tracks are astroturf. And if want a quick fix for traction rolling, or the grip is insane and I have done everything I could, then I go up on the tower.
If you go up on the tower in the front, then the steering will be smoother. And sometimes, this is enough to stop the traction roll.
And wider hexes are also, but remember you'll lose traction. As long as there's enough grip, it doesn't matter that much.

Nice Job, Blake. What kind of surface are you racing on and what setup did you use? Or what changes did you make to dial the car in for your track?

My new FAVORITE car!!
Switched from a B44.2...this XBR4 is incredible!
The quality is superb (except for the servo mounts).
The quality control is ok; one of my drive shafts wasn't bored and tapped, and I had to get a replacement from RCA.
The build is sweet; ALL screws are the same size (different lengths), so you can use the same wrench!!
Manual is very nice, with great images.
The diffs are CREAMY smooth and super easy to work on.
But...the DRIVING....oooooo...so nice!!

Bleeder Screws DOWN!
YOU BETTER BELIEVE IT!! Ironic you said that because, after months of fighting with clay-packed screws, I went through my whole fleet and turned them all downward! I actually got a second opinion from my shop, and he said they all do the same thing.
So, there's another dumb thing that's left out of the manuals. How hard would it be to just flag another "pro's tip"? There's no advantage of having them upwards; aside from marketing pictures.
And, YES, I can bleed all of them (4.2, T4.2, 44.2, XB4) without unmounting the shock.
And, YES, I made that the shock mount collars were correctly oriented.

Waiting to see if TLR is gonna do something, if not I may get one of these!

I'd be interested to know, those who have had the Durango DEx410 before your XB4's, how does the Xray compare in terms of strength, space and ease of maintenance?
I'm thinking of switching over.

Here is a little wing goof I tried this past weekend and it worked out very well!!!
Before cutting the front of the wing I left on a little bit of extra lexan so it can "rest" over the rear shock tower thus keeping the wing straight after accidental flips. My joking around worked! I figured once the lexan starts to rip at the 90 degree cuts I would just cut it right off.
On my next wing I'll cut it more rounded than a 90 degree cut.

Over the XB4, I just drove it last weekend, it is a very friendly buggy, easy to handle, not so aggressive compare to Dex410v3, more flex and needless to say parts are more durable.
