| Un-Sprung Weight
I do not consider myself to be Hardcore (due to finances) but I was thinking the other day about un-sprung weight. I have thought about it for my flat track race car (79 mdl ford escort mk2). Weighed up the pro's and con's and decided that at high speeds that it would be too dangerous........Braking with unsprung weight no good, High speed cornering no good etc.
But in rock crawling and low speed situations unsprung weight might pay off keeping the centre of gravity low etc.
Just thought I would bring up the topic to throw around some sugestions.....

| Basic rule of thumb-
If you HAVE to have the weight, carry it low. unsprung is typically gonna be as low as it gets.
But, less weight is better than any weight carried anywhere.. (Says the guy who got his cruiser under 4k just to go back up over 4500+) | |

| between the width, and the added weight of dana 60 axles, my rig is incredibly stable now. When I first swapped them in I was leaf sprung all the way around, and it started to flex like never before.
Heck when I had Toyota axles, I was worried when I went from 35" BFG's to 37" MTR's, and I could tell a difference weightwise.
I think unsprung weight for what we do is a good thing  | |

| I took it up to 60 on the freway last weekend. As long as the tires are fairly full, speed does not seem to be a problem..
