i see lots of material for lip and body kits.
have any idea what kind of material are?(Urethane, poly Urethane, Frp, Hybrid Aero, and cf)
somebody explain to me the difference for these material.

 

First of all, you HAVE GOT TO CHANGE your s/n. It's not polite to copy.
Secondly, FRP is good and felxible

 

Urethane > all

 

Urethane > all +1

but i thought urethane = polyurethane? idk. i just always have good experience with polyurethane, it fits better, flexible, doesnt break very easily, add flex agent to paint and its going to be real tough.

fiberglass = fitment sucks, body shops hate it and charge you alot of money, hit a curb and its over. hit a cone and its over lol.

FRP/Hybrid is a fancy name for fiberglass mixed with crap, might be a tiny bit stronger but still the sucks in my opinion.

CF is carbon fiber. Its expensive but looks cool. haha.

 

Polyurethane > Urethane > FRP > CF > Fiberglass > Paper Mache

Urethanes = Flexible, OEM-type material, very durable, 99% very good fitment
FRP = Fiber Reinforced Plastic or something like that. Flexible(?) (I don't know much about FRP, someone enlighten us?)
CF = Carbon Fiber. Looks nice. Brittle like fiberglass.
Fiberglass = Cheap, cracks, brittle, requires refinishing before painted, questionable fitment
