What rear suspension for bracket racing.

I would run Caltracs (The full set up with the mono leaves, link bars, and shocks). They work very well on my car, even when it’s super hot and slippery out they will at least slip consistently.
You would run all that on a 13 second car???I get that there are hardcore serious racers here who will settle for nothing but the latest greatest (and need it) but on a 13 second car?? Absolute overkill and a waste of money at that level. You gotta remind the gallery here what your car runs currently, how about what you used long ago when you only were making horsepower that was good for similar et’s and mph as the OP is projecting.......so everyone here can keep things in proper perspective. :)
