I made a video of my 530xi with a couple gopros & measured the performance with a pbox. It has the full Umnitza M5tech body kit & the F10 M5 wheels. Also i put a gopro on the outside to hear the Rpi muffler. Its not fast by any means, & 99.9% of the time I baby her but I was in the mood to make a little video!

1080p & full screen it

 

Nice car, are you happy with the fitament of the umnitza bumpers. Looks really good. Nice vid as well.

 

Thanks! I am satisfied with the bumpers, the front bumper lip (lower ground effect) isn't perfect, it doesn't really sit flush with the rest of the front bumper & the rear stick on spoiler is already peeling up (but that's fixable.) Since its black the bumper lip isn't very noticeable. Overall I am happy with the way it looks.
If I had to do it over again I wouldn't think twice. Umnitza has been easy to work with and very responsive whenever I email or call.

 

Did you use their paint serivce with your bumper?

 

BTW, car sounds great!

 

Same here, I would like to know how good was their paint as well?

 

Keep in mind though that his car is black or a dark color. It's relatively easier to paint match than lighter colors. While I don't have experience with Umnitza, I wouldn't pre-order a painted part from anybody for fear of the paint not matching the fade of the rest of the car.

Car sounds awesome dude!

 

^ yeah, I could imagine. I got a roof spoiler from ebay painted and it's a little off from my car's color

 

I actually didn't have them paint it, it was done locally after they were test fitted first.
