The truth about caltracs

I was just rereading some of these posts on caltracs, and noticed all of the bigger engines w/ caltracs, all have big , or good sized slicks. .
I don't have anything but 3/4" offset hangars and 295 65 15 d. radials, and the cal tracs aint doing squat for me so far on my 108" wheelbase. Thinking about putting my s/s springs back on-----------
Mine is a 28-10.5
