hey, im about to build a new mini and i need info. the black plastic side skirts on the mini. i was wondering if you could make them again out of fibre glass and then fibre glass them back on the mini so it blends in.

Can't see why not.
Just be aware that if your wheels bottom out onto these flares, that they will most probably crack the flares.
Don't want that happening now do we?
You can lower your bump stops (or add them) to prevent this happening.

Thanks for the question.

Will.
