(1)AAR is simple the straighest and best fitment.Some times just as heavy as the steel part.The Gelcoat will always shrink 100%
(2)GlassTek is the best race parts.They have built me some carbon parts but not much lighter.There gelcoat is much better.
(3) The real deal carbon is out of this world price wize.
(4)The worst I've used is WS and Unlimited.I throwed a hood from WS in the $hit can.Not even fixable.
You guys can take this for what it is!!!I have only painted and installed about 40 AAR hoods,rollpans,bumpers,fenders and about 25 from GassTek.
