ok so i just looked up extreme dimentions, including ondergrounds website
they all say front Bumper - urathame and then describe the other parts but DO NOT say they are urathane, therefor technically it doesnt say they are urathane.... i should contact their tech support and see what they say
their kits to me look like they are front urathane, and sides / rears are fiberglass, but i just wanna see what they say to potential customers
trust me tho, you will like your kit, especially if its being custom fitted.... i took soo many pictures of my car in the bodyshop... i think ther eon facebook, check them out
you remember my mx6 right?
