How many licks does it take to get to the tootsie roll center of a tootsie pop???
The world may never know....
I've never paid attention to even look...
you should have enough clearance that it never comes into contact with metal....if you look around the lower control arm pivot shaft on a 340 car you will see extra gusseting has been added at the factory where a slanty or 318 k frame do not have this...I have seen the lower control arm pivot sleeves completely ripped out of k frames before
When I had the stock lowers I cut 1/2" off the top of the bump stop and had a 1/2" gap.
Guys run on the bumpstop and run lower profile tires to get that modern look and then wonder why their "cheap" headers hit.
I'm not much better, I have brand new bumpstops and have just a little clearance cause I too like the lower look. At least my Jegs headers haven't ever hit with this and 215/60/15s. That is on stock regular 318 tbars.
When I bought my Dart they were mashed like an over-cooked potato. Put new bumpstops on, adjusted the torsion bars and have close to 1 inch clearance. Big difference in the ride, no more metal on metal crash at every bump
I'm surprised that no one has pointed out the obvious -- that if you are actually hitting the bump stop, at that point you are driving a coal cart with zero suspension. Even F1 cars, running enormous downforce, have some suspension compliance. On a geometrically smooth plane of asphalt, you might not need any compliance, but in any real-world situation, including autocross and race tracks, you have to have something, or you wind up bouncing wheels off the ground. Not only do airborne tires have zero grip, the instant transition from full contact patch to zip tends to really mess up your line. A little rubber or poly in there to soften the transition is a good idea.
Exactly what I did. Trimmed on a band saw. Running .92 T-bars on street car. Oh yeah, also beefed the LCA pivot with extra material and the K is completely welded. I'll have to put some kind of tell-tale, clay or something there and see what it's doing.
If you'd like, run this. I think it's a good idea to.

Agreed 100%. . There is a measurement for street use. It is reached by getting the ground height difference between the lower bushing pin and the ball joint. If you want it lower do what ever you like. Its your suspension and tires
