just search past threads. really quickly though, fiberglass is pretty low quality, stiff, and easily cracks. Go authentic, and unless your loaded, just keep an eye out in the for sale section and buy second hand parts

Hmm, I've got an idea with this thread.

Fiberglass/FRP(Fiber Reinforced Plastic) vs. Polyurethane: Pick your poison.

Lots of authentic kits are made from either or both materials.

Both materials have their pros and cons.

Fiberglass/FRP:
--Pros:
-Lightweight
-Easily repairable
-Easily painted
-More affordable
-No sagging
--Cons:
-Easier to break


Polyurethane:
--Pros:
-Very resistant to breaking
--Cons:
-Painting requires a few more work for adhesion
-Will sag over time due to heat/sun
-A bit more expensive
-Repairing polyurethane will be really difficult. Most shops won't even bother.
-Weighs a bit more than fiberglass.



Another material used is ABS plastic. Not many kits come in this form. One popular example would be the Mugen/M2 front lip.
It has the pros and cons of Fiberglass with a bit of resiliency of polyurethane.



Flex-Fiber, DuraFlex, any body piece advertised as being made with both fiberglass and urethane will have both characteristics of the two.


I've owned fiberglass, polyurethane, and ABS plastic pieces.
I enjoyed the benefits of polyurethane because I would run into minor accidents.
I enjoyed fiberglass because I could repair it myself.
I'd scrape with both, make holes on the bottom, but which one do you think was repairable?
I've painted both types of material. I've put a bit more work into prepping urethane than when I painted my fiberglass pieces.


It depends on you, the driver. Both materials are great, IMO, but it really depends on how capable a driver you are.
Most tuners like polyurethane because of the fact that it's less prone to breaking.

Now, what's your budget?

Authentic kits cost $$$. Replicas are far more affordable, but depending on the kit itself, it might cost you more $$$ to make it fit compared to buying an authentic kit to begin with.

Authentic kits fit as if they were an OEM spec piece. Craftsmanship and fitment (plus hype) is what makes them expensive.

Replica kits are 50/50. You either get one that fits like a glove or get one that doesn't even come close to mounting on your car. They are the more affordable option. Quality and fitment is a gamble.


Jintei is a site vendor that caters to the body kit tuners. He sells replica kits.

ViSracing.com is a Giant in the replica kit world.
I've personally owned 4 different sets of kits from them, all with fitment ranging from 90-99%. Quality has been 90% as well. I have had good experience with them, myself, but can't say the same for others.

eBay has replica kit vendors. It's been common knowledge that eBay is the last place you want to get a kit from. While that may be true, a few people here have actually purchased kits from there and were pleased with the results. I'd say you have a 70/30% gamble with eBay.


There are also online dealers that carry authentic kits:
-www.kamispeed.com
-www.mvpmotorsports.com
-http://www.suprastore.com/inexac.html


Other replica kit dealers:
-www.extremedimensions.com
-www.aitracing.com

Wow thanks Zero great reply :)
Mind you, those are my own opinions. Having owned and worked on both material, I have a right to state such opinions.

Others might have different beliefs, but like I said, it really depends on the person buying it, i.e. you.

well.
fibreglass is easily repaired.. but at the cost of repairing/repainting.. i would suggest you to get urethane.. **** happens on the road.. a rock flies at you and it might crack the bumper.. then you'll end up spending a couple hundred repairing that POS.
No it does not sag, but fibreglass tends to cause paint to spider crack at corners and stuff..
affordable.. yes, but u get what u pay for..
on the other hand, urethane kits.. are very limited but still nice. wont crack, wont spider crack, etcetcetc...
sagging.. it depends.. oem bumpers dont sag.. unless u leave your car out to cook for the whole entire summer with no shade then yes.. but common sense, you drive around, u park here n there.. chances of it sagging.. is very / extremely low..
expensive.. but well worth the penny.
if it cracks, it will cost a bunch but thats IF.. majority of the time. it will just dent in.. and all u gota do is heat it up with a blow dryer.. and punch it back out.

fiberglass also has different qualities and different grades. some are heavier, lighter, thicker, all a combination of fiberglass material and resin quantity and quality.

depending on the grade, rock chips only damage the paint (same as urethane), fiberglass will also flex and adjust better. It all depends on the prep work involved.

if you are a newbie and are going to paint it yourself get a urethane. usually lasts about 2 years due to sag and weight. But if you are going to go show, then bodyshop will charge you a fortune trying to get it to fit right unlike fiberglass.

best bet is fiberglass and get the a clear sticker/film to protect against rock chicks.

also get authentic japanese bodykits or japan spec fiberglass

worth the money.

I would ask them if I could test fit their kits. Since you're local, it might be worth the shot to ask.
Even if all replica kits need "professional installment" it should not require a shop to chop the kit in half and either cut a portion off or try to add some inches on. "Professional installment" is an umbrella term, which the buyer should really be aware of when purchasing.
I suggest asking the vendor Jintei about his supplies - he allows local fitment tests. :thumbup:

To go with your question, I know of no one here that has a duraflex/flexfiber kit.

thanks zero, im just doing more research, from looking at the promo video by extreme demensions, it looks pretty good. I noticed that poly urethane price has been going down. Would this be because maybe low demand or so? I almost bought the blitz here locally for 270 front bumper only. I stumbled onto extreme demenisons kit for $500. Still pondering.

Yes. You live in Anaheim... just take the time to go to Extreme Dimensions and ask if you can fit any of their duraflex kits. If they don't allow that, take you business elsewhere.

Like I said, "Professional Installation" is one thing, but when the shop needs to chop up the kit because it has fvcked up fitment and either needs to be shortened or extended to fit that is a totally different thing. You might as well fit and contour a cardboard box to make a body kit.

ViSracing should be in your area. I've dealt with their body kits countless times. And of those times, I've only needed to trim off excess pieces to make things fit - not cut the bumper in half and either shave it down a bit and re-fiberglass it together or cut it in half and fiberglass some extra length to it.


Why are you fixated on Duraflex any way?

I think the main thing people find intriguing is that duraflex's video on their website has them literally kicking, dropping and slamming a baseball bat into one of their body kits.
That's what got my attention when looking at their site but who knows if its legitimate consumer advice or a simple selling scheme. I'd also be interested to hear what people think who have bought a duraflex kit.

Here's their demonstration video, you'll have to sit through some bad acting.

Another question for you guys, in terms of weather conditions which material holds up better in extreme temperatures like heat waves or really cold winters, im guessing Polyurethane?

Nope. In extreme heat, Polyurethane will start to sag. I'm assuming it'll turn brittle in extreme cold, to the point where it's flexibility becomes compromised.

damn...so fiberglass would be more resilient towards weather? Mind you I'm in Vancouver and even though we have hot summers I doubt its extreme heat, the winters on the other hand can get pretty cold.

Over time, weather and temperature conditions will effect polyurethane as opposed to fiberglass.

Did you read my pros and cons?
