i was wondering if what you guys thought about Urethane made body kits. I have never even heard of it but from what i read it seemed nice. I was just wondering if you guys would suggest Urethane or Fiber Glass body kits?!?!

Urethane is much more durable than fiberglass. If you can pay more for a urethane version, then I'll recommend you doing so. :yesway:

ok thanks a lot. I dont have the money now but im close to having it i think ill go ahead and save some extra for a urethane body kit.
Yeah, good idea on waiting to get urethane. You'll going to regret getting fiberglass when it starts cracking over time and sometimes even "warping". Do yourself a favor and save a little extra so you don't have to end up replacing them again in the future.

if your car is strictly a show car then fiberglass isn't a bad idea but if it's a daily driver then definately urethane

Urethane is much more difficult to paint (more expensive), isn't fixable, and very difficult-to-impossible to customize (atleast if you want to maintain the rigidity of the urethane). Painted urethane parts will also often fade at a different rate than your other body panels.

There are pros and cons to both; personally, I greatly prefer fiberglass. If you don't drive like a fucking idiot, then the small amount of flex that urethane affords doesn't really make a difference. And even if you do run in to something, its comforting to know that fiberglass parts are easy to fix, whereas damage to a urethane part requires a complete new piece+shipping+paint/prep+time to get said part and time to have painted and installed.

Urethane will most likely fit out-of-the-box better than a fiberglass kit, mostly due to the stricter manufacturing process urethane requires. But realize that the urethane part isn't ever going to fit any better than as it does when it arrives at your door. Not a big deal when you are talking about, say, the WW kit which seems to fit great; I don't have nearly the same confidence in urethane kits from VIS. Fiberglass can easily be trimmed, added to, or filled--nevermind REINFORCED--in order to fit any application you can throw at it. You can manipulate fiberglass in any way that you can imagine, which is not something you could ever do with urethane.

As for the "cracking" that someone mentioned...how do you figure this? If your fiberglass part is cracking, it's not due to anything inherent in the qualities of the fiberglass itself. If you want to see cracking, watch your urethane parts shatter like glass when you bump something in cold weather.

:agreed: Okay, that's true. I never really thought about the cost to fix urethane and fiberglass. I have a friend with a 2G and a blitz kit and his front bumper was fiberglass. He tries to drive it as carefully as he can, but with the car only about 2-3" off the ground, he'll scrap/bump into a few things. His bumper pretty much tore itself apart so he got the urethane version, and it seems to be taking a beating a lot better than the fiberglass.

I do see your point that fiberglass is better in terms of cost, though. I'd imagine since urethane is harder to produce/fix, the cost will be higher. :)

Im pretty confused on what to get now but i think ill get the fiber glass one since ill eventually want to mold it in. Its a cheaper paint job and i drive real safely. Plus my car isnt sitting 2-3" from the ground so i wouldnt have to worry about my front bumper. Anyone have any suggestions on some good body kits, ive looked around i just want to see what other peoples opinions are. I really dont like the blitz kitz personally and i see those everywhere on ebay. But anyone have any suggestions i could check out?

If you want a nice fiberglass kit, I would go with the Bomex style. When I took off my Blitz kit I was amazed at how much thicker the Bomex fiberglass was. The blitz fiberglass was like paper compared to the durability and thickness of the Bomex.

Although Urethane is much more durable all around, its a bitch to deal with.

Depends on what look you're going for. If you want something that adds a little style without being overly agressive looking, go for the Wings West Type W.

i dont want anything agressive i just want something that makes it really nice looking beacuse i only have an rs and i just want something thats not agressive but a nice clean look. Its hard to describe what i want. lol
From what you're saying, the Wings West type W is just what you seek.

I think that, myself, will be going for a SS Replica made in all Carbon Fiber. It will be a little more, but it should be able to uphold better than the fiberglass version.

Correct me if I am wrong Mark. :)

I think you're good :) I have a full CF ShineStreet front clip and sides with a fiberglass rear (no CF SS rear was available when I bought it). Here again, the only scary part is that some of the cons of urethane are present here. It is only going to fit as good as it does out-of-the-box, and you would not be able to mold (you can ADD glasswork, but that area would have to be painted and not left as exposed CF).

Fortunately all my parts fit good. I had the sides painted black (and rear, obviously). On the front piece I left the center section exposed CF, but the sections to the left and right of center were lightly sprayed over with black--you can still see the CF underneath, but not right away. It looks very cool. :)

I like WW, but for me it is a bit TO mild, the SS is a nice mix, more agressive than WW but not as agressive as most full replacement bumper kits.
I agree completely, and is why I went with the SS.
