I am just curious there are some people says it is the same material, is it ?
If is not the same what exactly is FRP ? Is so more durable? Compare to stock one which one is better ?

I found Velside3 replica kit with FRP and the price is not so expensive.
Finally do you know anyone who selling Urethane velside3 kit ? Replica one.
I want to go with some thing cheap, but if it easy to crack I don't want it.

Thank you

 

FRP and fiberglass are the same thing.

Fiber Reinforced Plastic:
This material is reinforced by the glass fibers in the polyester resin which strengthens fiber reinforced plastic products. A great property of this material is that you can form any size or shape while still retaining a large degree of strength. Due to these characteristics, FRP is widely used by most aero-parts manufacturers.

Compared to stock what? There is more than one type of material used on the exterior of a stock 350z.

 

Correct me if I'm wrong.
I think stock bumper is Urethane right ?
Which material is better Urethane and FRP ?

 

urethane bends, FRP cracks

i'd never buy a FRP bumper.
