How much clearance do you have before hitting the bump stops on your lower arms?

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.

I don't run cheap headers. Mine are TTI. But the car is very low. I've heard dougs are 3/8 to 1/2 higher up. When I put 275/40/17 it will raise the car up some and help.

I've high centered on crested driveways with the bone stock exhaust when the car was even lower with 225/50/15 tires. It would also hit parking lot curb returns. Not scrape, hit dead on. That was stupid low. I'm not doing that again!
