Bumper carrier swap from Alu to Kevlar

[old///MFanatic]

My research showed that the kevlar system is 1kg lighter...
the weight savings all the way in the front is a bonus I guess.

Yeah, Kevlar is an ///M upgraded part and still the better bumper carrier.

I went through this because the body shop (Fleiner Automotive in West LA) who was doing my insurance work fucked up and ordered the wrong bumper. Here are the threads with all the info you will need.

Thanks!

I ordered the front carrier and mounting parts two days ago. I will get back on this after I receive the parts and had a chance to install.

Cross reference the parts on realoem with a Kevlar year car

side note, interested in your bumper carrier shocks when you swap over. You’ll no longer need them

I have mine still if you need those. Also have the metal carrier.

More adjustment

That sounds like more ability to be in the wrong position

Be careful when buying a used Kevlar rebar. The aluminum mounting plate is bonded to the kevlar and it is common for the plate to be bent.

Lesson learned...don't mount splitter struts to a Kevlar rebar.

Alu is better than kevlar, but the front is specific depending on cover like you already know. Rear cover is the same FYI (alu/kev), so keep the alu so you can adjust vertically.

Why?

I cannot really say which one reacts better in case of impact.

I'm doing the swap because I have 2 free bumper covers, the weight savings all the way in the front is a bonus I guess.

Interested in what is the idea behind the aluminum being better than the Kevlar?

I have the same question.

Alu is better than kevlar

I’ve been planning on going with a new “euro” OEM bumper skin. Just cleaner looking. Interested in what is the idea behind the aluminum being better than the Kevlar? Now would be an easy time to switch if better.

Hi there,

I have seen some threats about going from the kevlar front bumper carrier to aluminum for CSL bumper fits.

I am trying to do the opposite, as I have an early model with the aluminum carrier and two bumper covers I got for free but they are for kevlar carriers.

So does anyone know if I just need the kevlar carrier itself or are there any other things I need to consider?

Thanks!
