My lowest point is 3 inches from the ground and people are telling me to lower the car some more
I dont have any problems with speed bumps or anything like that. What I do have a problem with however is road deformities that don't lift the rear wheels but come straight up the middle. I've scraped the mufflers a few times. Also rocks strewn across mountain roads are a nightmare and hit all sorts of crap under the car in addition to the FI Exhaust.
Edit: Looks amazing on your car!
