The folded strakes (surprisingly rigid!, no bufeting whatsoever) reside in aluminium C channels glued in with gorilla glue. Gorilla glue makes for an extremely rigid bond.

The C channels are attached to the diffuser with nuts & bolts. Compared to the wooden prototype, the coroplast version weighs half as much, 4lbs!!!

Nice work dude,

Good to see that you have made something in keeping with the aethetics of your car. I've always like the look of the new Mini (despite having an 'old' one as a track car).

You've defo set a standard for me to aim for when I translate my plastic undertray into sheet metal.

Looks great thanks for sharing, how did you anchor the front? Have you seen the retro fit GP body pan??

Next time i'm under the car I'll have to take a pic of the front attachment point.

Yes on the GP underpanels. More common though, people retro the r56 panels for the r53 MINI, very similar to the GP panels but less expensive. Still, these are much more expensinve than my $20 4x8 sheet of black coroplast

Plus, there is no gap between the underpanal and the diffuser...the two actually attach to each other.

Cool that would be great, yes very true on the $$$$. My side skirts are made out of plastic rain gutters and the front air dam out of a rubber which I run year round.

Hey, John. How about a picture of your side skirts out of the plastic rain gutters? Thanks.
