Default R&D cross frame is on

I installed it yesterday.. I was a pretty simple install, the hardest part was having to crawl in and out from under the car. It does seem to hang a little lower than I expected but it does add quite a bit more rigidity to the frame. Has anyone installed the behind the seat cross-bar? If so, How much more of an improvement was made?

Nice, ain't it? Yes, I installed the cross bar first, then the camber brace and recently the cross frame. When I first installed the cross bar, it was a very noticable improvement. Besides being more ridgid, I noticed a much better feel on turn-in when hard cornering.

Excellent! The cross-bar is next on my list then probably the camber brace.

You can get it all welded in one piece now and there is a big improvement in ground clearance. I started with a Cross Frame, added the Camber Brace and then the S/T Frame roll bar. Wow what a stiff chassis...

Looks great! Thanks for the pictures. I have a cross-frame on order. Any tips on drilling the rear mounting holes for the nutserts?

Had Dave at R-D weld mine too. The Cross Frame really helps the handling.
I had the Cross Bar before I got R-Ds S/T Frame Support (aka roll bar), it really helped in the handling!
