'70 Dart 392 Project; what direction?

You don't need a pinion snubber with Caltracs because the bars prevent axle windup. I run the Hotchkis springs and didn't have a pinion snubber for a while, but put one on to help prevent axle wind up. I do feel like it was beneficial. Depending on how you drive your car, you may be OK without one, but I do a fair amount of hard standing starts at the autocross and at Moparty when I drag race and speed stop. I've also modified my pinion snubber so there's only about 3/4-1" of clearance before it contacts the floor.

Perfect answer thank you. I’ll be on the lookout for one for the 8 3/4 build.
Car will be a toy/fair weather driver. Doubt I’ll hit any track more than 4-5X in the life of the car but I’d like to give these 315 series tires every advantage they can get on the street.

Yes I have RMS spring relocate brackets to bring the springs inline with the frame rails.

Looks like I’ll roughly have 2” of width clearance for the tires in the wheel wells. I’m assuming I should place them in the center? Handling logic tells me the wider the better but I’m unsure of how much sidewall flex I’ll have with these.
