It basically seals the gap between the diffuser and your bumper so that dirt, leaves, and other junk doesn't get stuck in between. Check the box that it shipped in. It probably ended up getting stuck in some of the packing material.

 

Looks real good with the TOMS rear and the LED reflectors. Do they come on when you brake or are they on constantly like the DRLs in the front (for those who didn't opt to have them turned off)? The weather stripping will definitely block out the gunk and stuff that might be susceptible in slipping the crevice between bumper and diffuser.

 

Thanks for the heads up guys.
And the led reflectors are wired to tail lights and brake lights, so yes, brightness will increase when braking.
I could have wired them to the parking sensors, but did not want them on with DRLs.

 

Cars look sick bro! Please PM where I could get one. And the iJDMtoy.com bumper leds are a great touch, I think they look cool and the judges at the car show loved them

 

i have the 3m grey molding tape if you want it. i used the black one on mine , both came in the toms kit.

 

AAI Motorsports for the Tom's diffuser (USA vendor).

And I am not worried about the weather molding at all :P

 

It turned out great! I'm glad to hear you got the fitment problems taken care of with the diffuser and exhaust.

 

Hey I have iss forged exhaust as well and I'm having troubles sticking the diffuser to the bumper beacuse the tips makes it so tight it doesn't stick. Any tips on how u got urs to stick?

 

Use 3m primer promoter pen and 3m vhb doublesided automotive tape. Use legit 3m brand

 

Don't be scared to push it on with more force than usual. The CF should be able to take it.
You need to coordinate both sets of tips with each other when pushing it on--this is a two-person job.
