Has anyone here bought this diffusor from shine? Would like to know how fitment is and if any hardware is needed to install it.

 

I don't have any direct feedback on that product but there are two things that Ken at shineauto is known for:

• Making great products & customer service.

So if have any questions about what is included and/or how to install, shoot him an email or give him a call. I've spoken to him before and he is a great guy.

In the mean time here is a GB thread with some feedback on the diffuser:

I ran one on my car for 2 years. The fitment was overall pretty good. I had to trim a bit under the car near the diff for my exhaust, and getting the tabs on each end to sit completely flush against the body took a bit of effort, but it was solid once installed.

I plastidipped some of the rear bumper to blend in those mounting points a bit.

 

Thanks for the feedback guys!!
