I just installed the APR CF front lip.
FYI = PITA
Not hard but frustrating..
Under tray is a real pita to get those pop fasteners off.
Even harder getting them back on after lips attached.
Did it in my garage at midnight on ramps, with me underneath on a roller.
Would have been 100 times easier if you had access to an overhead lift.
It's alot easier to get the fasteners back in if you can do it while it's in the air from underneath.
APR lip went on snug and looks great.
But the under tray is pretty aggrivating.
The fasteners just dont want to go back in without a little coaxing, and some pushing and pulling and alot of cursing - LOL..
The tabs on the lip and the holes just dont wanna line up right on some of the tray holes.
Either that or they get pushed up when you try to push the fastener through
and then it wont catch right and is almost impossible to do by yourself
and without an overhead lift.
{need 6 hands to push/pull and attach.}
A bit of a headache but well worth it, imo..
here's some quick pics. in my garage right after install
Install time / 2-3 hours on ramps -- If you're lucky and the fasteners go in easy and no help..
Install time / 1-2 hours on LIFT -- with a little effort, and some extra hands..
Good Luck...
