GT3 bumper problems... I'm Frustrated!!!

There's nothing wrong with fiberglass as a material. An overwhelming majority of the best
"tuners" and manufactures use it. Moreover, by virtue of the fact that it can be "manipulated" and "crafted" in ways other materials can't be, it has it's benefits. It simply requires the right individual who has the experience and skills necessary to work with it .

Fiberglass takes alot of fineness to pull a clean part out of a mold. Traditionally fiberglass is going to continue curing and warping as it does. Mix the resin to hot to rush it=heat& warps. To mix cool and it will take forever to cure but a much cleaner part

In general, a bad, rushed part takes alot of filler to straighten warps . The warps need to be blocked out.. If your car is a light color, it won't show as much. If it black, I't got to be blocked out dead nuts, lany little warps will show like moguls.

So glad I came across this post as I was at my wits end thinking about it myself too. I think I'll just fork out the dollars for a factory/oem kit. Might not have the dramatic look but at least its clean, and hopefully without complications with the peace of mind that it's designed to fit correctly as it should whilst sticking to the cars relative vintage without going overboard. Really hard decision which I'm sure we all have spent countless hours or days even weeks pondering about

However I assume this was all about the fiberglass version? How about the polyurethane version? Anyone tried that yet and how did it fit? Any problems?

fit is lazer perfect. Durability is light years better than fiberglass if you drive your car often, particularly on crappy roads. Fiberglass does not like to be repaired once broken. I would only use it on sideskirts unless the car is a garage queen, then maybe you can explore front and rear fiberglass bumpers. Otherwise go with polyurethane, there are some aftermarket options with this materials but not many.
I'm about to have my GT3 bumper repainted for the fourth time and virtually every single time I had it painted it took only a few months before l hear "crrrash" on a steeper than anticipated driveway, high manhole cover in a construction zone or random crap on the highway I ran over. But the K turns into a drive way are the single biggest culprit. Do yourself a favor and drive around the block.

Thanks mate, as per your very reasons, I'm trying to avoid fibreglass and stick to polyurethane. However, as you cannot alter polyurethane bumpers, they therefore need to be made to extremely high standards in terms of fitment since you can't simply add filler or file things down to shape.

Has anyone here had a polyurethane front bumper or kit installed on their boxster and is damn happy with the fitment and presentation? If so, please chime in and advise where you got yours from?

Thanks guys
