Have you "Autocrossed" your Challenger Recently?

Thanks Wasp. I'm not lowered and only looking to run 18s for autox. Still think I'd have clearance problems as some of our sites are a little bumpy

I think you'll be fine if you're not lowered. I have 28 1/4" clearance from bottom of my fender lips to the ground with my 20s and coilovers. No issues at all on the streets.
With everything stock I was at 29.5" in the front and 30.5" in the rear to just give an idea.
Also, with my 18"s I'm at 25.5" from bottom of the fender to the ground. That's way low.

My 285/20s are 27.6" tall and the 275/18s are 25.6" tall if i remember right.
I'm lowered on mopar springs, so maybe an 1" of drop.
I do drive to/from events on race tires but the roads aren't horrible. I'm also lucky that all our events are on the site of the scca nationals , so the tarmac is pretty good.
Top of 2nd with the 285s is 64mph. This is one of my biggest fears with the 18s. It will take me from a 4:04 gear to a 4:41. I don't want to be topping out a 58ish when the mustangs are pushing 70mph in 2nd.

Yea with my 245/19s I'm topping out about 62. What I have going for me right now is 90% of our locals are smaller lots so that hasn't been much of an issue but I do want to run more national tours next year. Wasp what do you top out at in 2nd on the 18s?
