Inside and Out - What is the best lip material?

Im looking into a type r front lip and wondering if I should get a ABS, fiberglass or urethane one? Which one has the best fitment? thanks

Poly.

I have heard to get poly, becaues it stretches a little which makes install a little easier.. ABS is next, and almost everyone says never get fiberglass..

get poly it will make the fitting process alot easier

poly and ABS plastic and you wont have any fitting problems and they can both take a beating..my ABS lip can flex like a normal bumper, but my poly front lip...i can bend it in half and twist it around, you cound run over it and nothing would happen

i've got a polyurethane, and i love it, it has a perfect fitment, and it doesn't crack, it just stretches
