Jason (AngryEvo8) did a awesome job on these. On the Junk Box i am running the mirror block offs he made. I think they look good on the Evo 8 bumpers. Looks agressive. Good thing about them is you can take them off whenever you like Congrats on the new personal best time as well!

We used 3M double-sided tape to mount them. The pieces between the logo use the factory bolts on the bottom and tape at the top. I'm going to play with the fitment and try to mold the bottom pieces a little better with a heat gun when time allows.

You'll see a lot of drag cars with full fiberglass front ends with no openings to keep the car as aerodynamic as possible.
i understand its concept to guide air around the bumper instead of being trapped in the corner holes of the bumper. but again why not just use the small ones you can glue in from the back of the bumper? do they not work the same?

If you're looking for a more permanent option that sounds like it would work fine. Unless we take a car into a wind tunnel we'll never really know which method is best.

Congrats on the new PB. I fiber glassed in a set of the ones Jim K made(the ones sold on 9sec9 and BR website), I'm hoping they perform. What tires were you on?

Thanks! Post up some pics of what you did, I bet it looks slick. I was running 17x7 MT motorcycle slicks.

I don't have any cleaned up pics or pics of the bumper on the car but here is a quick snap after I finished the glass work. I just put a small amount of epoxy on the blockoff and then glassed around the back to make sure they stayed in place. I wanted a more low key look to the front end and being permanent wasn't a big concern.



I wonder how much the mirrors effect mph in the 1/4

My coolant temps stayed in check, I usually let the car cool down after 1 or 2 passes though. Daily driving with them on probably wouldn't be a good idea.

Yea but it still lets the bumper direct air into the pockets and create more drag then just letting it pass through. The point of the other ones are to BLOCK off the hole, redirecting air smoothly with the contour of the bumper.

OP

Send me a set to test on my new 8 (10.2@141mph), I can do a review and send them back or buy them afterwords if you like. 3 weeks left to make passes for me.

I can see your point. Makes sense but I think the smaller block off will perform just as well. Being we are trying to push a brick threw the air and most guys are under 150mph I dought there is much difference between the 2 versions. Imo it has to look good and perform. I am not digging the look of the block off for the Evo 8. The 9car bumper I think looks good. Well better.

I agree completely and without wind tunnel testing it is impossible to know exactly how either one performs. I wanted the best of looks and performance combined. I know for a fact my driving would be more inconsistent than the difference in the two types of shutters.

To the OP. I don't think yours look bad, they are removable and are for strip purposes only so I think they are great for the intended purpose.
