Hi,
I bought a lowered RX8 with INGS Full body kit, I really like the car it's great only problem is that it's my first lowered car and I scraped the bumper a couple of times, the other day I was driving around and I tried to go into parking and I scraped my front bumper from the bottom which applied force on my side marker. one of my side markers fell off and the mounting part is still there but it's detached from the side marker itself, how can I fix it? I tried JB Weld but it doesn't hold,plus it doesn't align withe bumper. I also noticed that the side mounts for my bumper are a little bit beaten up, Is there something I can do about it? Can I rebuild them? Im really scared that if my bumper scrapes again something else is gonna fall. I'm gonna raise the car a little bit to prevent the same thing happening in the future but still, it kinda sucks.
Thanks.
