Arrow Renntech Style Diffuser - Trouble Fitting
Hi Guys,

Bought a Renntech style carbon diffuser and its proving to be a nightmare to fit, the sides (above exhausts) keep pinging down and wont stay in place at all.

Anyone have any tips/suggestions?

Cheers
Karl

I lowered mine down a little. Had two people help. Screen one end and the other so it had to stretch and provided a VERY snug fit, but each diffuser is different so that's just my recommendation to you.

Dremel, ehhh? i bought the factory rear fog deflector but it doesn’t fit. Too long and not curved on the ends. May just dremel the reflector and epoxy it in. Thanx for the idea!

Looks good with both options imo.

Im about to get mine installed too and seems like the way to go is to remove the bumper for this to happen huh. Any underneath pics of your diffuser installed? Interested to see how you mounted the tabs and where you ended up screwing it in the body of the car
