Ok so at first I realized didn't even have fender liner so I got it replaced. Not even kidding its been maybe 2 weeks and its completely cracked though the middle and about to fall off again... Why is this happening ?

are you lowered? stock suspension?

no not lowered and yes

Stress cracking, has your G been in an accident at all?

Get them from partsgeek.com. at $13/ea you can crack em all day.

urban im not to sure tbh. And no why would I want to do that? I just want it not to break...

Are they fully secure? Or are you missing some pushtabs? Are your shocks good? Maybe you're getting too much travel over bumps/dips. Cmon, man, this can't be that hard to figure out.

^ +1, make sure the fender liners are fully secured. There are 3 pop rivets behind the bumper, 1 at the frame rail, 1 up top, and 1 along the arch above the frame rail. Then a screw or two at the lip of the fender. Also make sure you secure the bottom section of the liner to the undertray and bumper.

Patrick from your previous threads I remember your beautiful blue coupe was lowered, if the liner isn't totally secured it's flapping in the breeze when you're at speed it won't survive for long! With our members help you know where to find 'em cheap.

I take some pictures today but I don't think its lowered. and all my under trays and stuff are warped and everything missing screws I need the whole under bottom to be redone lol I never realized it was so bad until I really looked at it
