Akrym AeroRace One vs RDSport bumper

Anyone know the weight difference of the two? Difference in build quality? What happens with cars equipped with headlight sprayers?

Not sure about the Arkym,

but the RDSport is made of Carbon Kevlar composites and is very light (getting weight info now, will update soon).

As for the HWS, you'll have to get the body shop to custom cut them out. Any competent body shop should be able to do that with no issues.

Here you can see the Carbon Kevlar Construction Up Close.


Feel free to PM me if you'd like more info /pricing.

Just got the weight info for you. This bumper is so light it's amazing. You won't be disappointed.

I love the look of the RD Sport bumper and it might even be one of the best looking bumpers on the M3 market BUT the RD bumper fits horrible right out of the box. On all our projects we had to spend 10 hours + to make it fit perfect. I really wish this was not the case

Does the Akrym have an additional splitter or is it all one piece?

100% agreed, and you guys did one hell of a GREAT job on getting it to fit.

From the pictures, this is a Fiber Reinforced Plastic (FRP), just like our car roofs.

The 'Fiber' part is obviously the carbon fiber and Kevlar, and the 'Plastic' is the matrix, most likely an epoxy.

There is no such thing as "fully carbon kevlar" because you always need a matrix material to support the fibers. Otherwise it would just be a soft piece of cloth.

Depending on the purpose, a typical high performance FRP can contain up to 60% fiber by volume.

From what Nate is saying, the outer layer(s) of the bumper is carbon fiber, usually used for strength and/or stiffness. And the CF is backed by layer(s) of Kevlar, a very tough material, which means it takes a lot of energy to break (that's why it is used on bullet proof vests). CF and Kevlar are infused by an epoxy to keep everything together.

Hope this helps
