Geeeezz ! how slammed are you guys !!
I know those lower Front H and Mid brace stick out about an inch or 1 1/4 inch at the bolt /fastening points
My Front is 1- 1.5 inch lower and minus the brace clearance
But that should still have enough ... except with those odd incline or steep speed bumps
I got a few bolt/fastening mangled up

Im Lowered About 2 1/2"-2 3/4"
I have just enough belly clearance that the end of my mid pipe that drops down slightly before going up to meet the axle back exhaust ever so slightly scuffs the top of avg speed bumps, I have to drive over 9 speed bumps to get out of my apartment complex.... yes... each way -_-
Only a few are "larger height than normal speed bumps" and those are the ones that if I dont creep over them i'll scuff the exhaust slightly, you'll hear a slight "Ping" but I haven't scuffed the belly anywhere while driving though.
I was helping a friend the other day and he drove my car as I followed in his, It looked like my exhaust would hit everything lol but it doesn't, I honestly feel I could not use these H Style chassis braces without clearance issues unless the were flush with the belly..

What do you folks think of the rear lower cross-member bar, a 4-point brace?

Do you have a link for it? Not sure what product you are referencing.

I've had one installed for quite some time now. It does what its supposed to do, stiffen up the rear frame member....
