I've never fitted these bud but it's your shout if you want to try bumpers that are glass-reinforced plastic, which is essentially fibreglass. Standard bumpers are plastic and they flex a bit without cracking and are considered a good fit with all mounting points in the right place. It can be a bit of gamble whether the fit will be good and if mounting points will be present or if you have to transfer or make your own in order to fit it, you could e-mail the company though if you're still interested.
Whoops, just read the product details and looked at the pics and it says no mods needed to fit and all fixings are present, which is handy.
