I ended up buying one from a guy in Russia. He had them made out of some sort of styrofoam but they didn't really fit. I had to cut almost 2-3" of width out of them and lengthen them but in the end, they worked perfect and attached to the underbelly floor pans.

There's a thread out there somewhere showing what I had to do but I know I have some pics here.

HTH's,

Mark

Correct me if I'm wrong a diffuser like that is useless without a flat underside right?

Your diffusers are perfect. I hate how much the m7/Challenge ones stick out. Somebody needs to start making them exactly like that, I'd buy them right now.

Yep.... that’s why I bought the Challenge bottom covers.

Contact them and ask. Their website doesn't stay updated very well.

Just thought I would wish this thread back from the cornfield....
Has anyone installed the Group 4 Autosport diffuser?
Was it a difficult install?
There is obviously some cutting involved. Does it come with templates, or is it a keep trimming 'till it fits kinda job?
Would I be better off spending the bigger money for the JCW rear bumper and the GP diffuser?

Thanks in advance....
