A couple of years ago I came across pictures of two or three Brats that had been extensively retrofitted with Impreza suspension and drivetrain. It was a shop in England that did the work and there were many pictures of completed Brats as well as interim pictures of the work being done. I've lost track of these. I think I posted the URL here on the USMB but haven't found it yet. I'm hoping someone else with a better memory (or computer skills) than I can find this. Thanks for the help.

Would deffinately like to see this.

Reminds me of the Rockstar GTO

A Judge-Body GTO on the newest generation GTO drivetrain.

These Brats will be so much cooler.

Not exactly what you asked, but here is a UK company that has done Impreza pick-ups:

Wow, didn't know it was this one. I've seen it at another place on the internet before. Deffinately looks cleaner without the giant intercooler up front.
