hi ya,
Whats the difference (bodykits)
1.ABS
2.PP
3.PU
4.Fibres
???

Re: Whats the difference??
well I had Fibre on my last car..kenna bump, sure cracked.
Some said PU is better, more flexible but hard to paint.
Then some say PP better, lighter.
For me , it neber got better coz still blur.
U guys using what arrr??

The Fundamentals of Fiberglass - Fibre Glast Developments
Bodykit Material - Poly Urethane or Fibreglass better? - Torque Online Forums
In short, for bodykits susceptible to bumps (like sideskirts and bumpers), stick to PU.
For other purposes, like weight reduction, go for CF.
As for the rest (ABS, FG), brittle and rough/wavy surface. Small parts like splitters can lah, dun use on big parts like sideskirts or bumpers. Imperfections too obvious.

too add...
if you are going for looks and on a budget, then ABS and FG are ok. but these tend to flex at high speed. it's also difficult to mount them on the car properly via the usual clips as they are thin and brittle, also can't use screws as they tend to crack.
PU parts are tougher and more rigid. so can withstand minor impacts better. and won't have as much flex, so they serve their purpose better.

Re: Whats the difference??
Actually, PU is a more flexible material, which is why they are a lot easier to install. The engineering limits/fits dun have to be as accurate as the harder and more brittle GFRP and ABS parts. The more brittle nature of GFRP and ABS also means they crack/chip more easily. PU is more resistant to bumps and knocks, but once damaged are almost impossible to repair, unlike GFRP.
I think what you perceive as ABS and GFRP 'flexing' as high speed is more that these materials, being hard and brittle, yield less under loading and hence squeak and creak and appear to 'flex'. In reality I believe PU flexes more but because it yields more easily under load, you do not 'see' or 'hear' the material straining. It sort of 'goes with the flow' more. Remember, PU was essentially developed as an alternative to natural rubber and is also used extensively as seat foam, which gives you an idea of its 'flexibility'. That being said, there are also grades of PU that can be rigid/semi-rigid - all depends on what your application is.
Anyway, there seems to be some disagreement/confusion in the torque online thread as to the cost of the different materials. I may be wrong, but I always thought the order, from the most expensive, was:
CFRP
PU
PP
GFRP
ABS
PP is the one I am unsure of, but definitely cheaper than CF and PU I think.
