How much lower does the lip sit compare to stock?
When you park your car, does it clear the curb?
Oh this is for the sport bumper.

 

a little lower. my car is not lowered so i haven't had issues with hitting curbs or parking blocks but i'm cautious as s*** when i park so i usually leave a little room between my nose and the block.

I know that if i lowered my car even an inch, my chin would scrape so i have cancelled all plans to lower my car.

in a sense, buying the lip saves you money since it'll eliminate the desire for coil overs or springs.

 

u'll still be ok with the parking blocks and the driveways. I drive through SF and haven't had any issues. freaked out one time thinking i was going to do cause I took a hill a little too fast. . I would say if our front end clearance is ~6.4inches, it'll bring the front end to about 6.0-6.1.

but yeah You'll need to get coil overs w/ the minimum drop if you want to stiffen your ride but not drop below most curb clearances. I haven't done it yet, but I've measured it.. h aha ha
