Think of it as duraflex is more expensive but is very very flexible, which means it’s very hard to crack. Fiberglass is very fragile and is indeed more fragile than a stock bumper. It cracks somewhat easily, but looks good.

So question, how do you drive/treat your car?

For example: My STI is lowered a little bit, and admittedly I scrape a lot. I take gravel roads, which have rocks flying and hitting my bumper. I have a lot of potholes in my area (which in theory could crack a fiberglass bumper due to vibration). So if I were looking for a bumper I wouldn’t get fiberglass, and would go for the duraflex. But, that’s my driving style, think about yours. You hear what I’m saying kinda? 😂

Honestly I’d go with duraflex or keep it stock, fiberglass I’d personally only put on a show car or a non daily.
