Make sure you get the CarbonSignal or Shine auto project replicas, (Carbonsignal is a shop out in Dubai) but they work with shineauto and the kits are designed in california. Sometimes people tend to call them carbon signal but they're really the same thing.

You can find the kit here, I recommend getting a front/rear bumper with the carbon fiber accents, it looks much better.
