Homemade Caltracs

Yeah,
Everyone says their the hot ticket for traction. I was thinking about them for my Dart .I wonder if I would have to swap out my superstock springs? I just got some MT SS tires (255/60/15) for my Dart in some Jegs wheels that are identical to my Summit wheels except for the center cap (of course Summit quit making the wheels). As a matter of fact it looks like I could pop the center cap out of the Summit wheels and put it into the Jegs wheels. I still have the BFGs mounted on the Summit wheels so that I can swap them out easily. I got a feeling that with the new 418 stroker engine (490 HP/516TQ) that I might need more tires than I can fit under my car without modifications. So the caltracs might be the answer.

I have quite bit more h.p. than u stated, the caltracs aint doin it for me --so far. My new intake manifold change made it even worse------
