CSL 1:1 Carbon Bumper

Tap right for info.

Complete carbon construction.

The vacuum infused carbon process was chosen for its high tensile strength, light weight and manufacturing accessibility. The bumper comes in at 3.7 kg.

The carrier is integrated.

Using a similar design to the OEM unit, this bumper features a pre-molded, integrated bumper carrier.

It fits with OEM accessories.

The bumper was designed to fit with OEM accessories. Read my hardware notes to learn more.

The splitters are OEM spec.

Using CSL matching 1x1 weave, the splitters are exact replicas made from pre-preg & autoclave carbon and finished in gloss 2 component clear coat.
Build journal: a special series
Genuine CSL parts pricing has skyrocketed.

Poorly fitting replica fiberglass bumpers are available from the usual suspects. My threshold was OEM fitment and nothing less.

At over 5,000$ USD excluding shipping, the Genuine BMW CSL carbon bumper was nothing more than a pipe dream.

I found a German made alternative.

In this Special Series, I documented the EU to NA logistics, unboxing impressions, fitment attempts and review of the final fitment & required hardware for the CSL carbon bumper.

Cheers,
- Matt / @m3_epoustouflant

Snorkel Variant

Dual snorkels

After many requests, a variant of the mold was created to offer a dual snorkel variant of the bumper. The CSL windshield fluid reservoir will no longer fit on the passenger side.

Hardware notes

The bumper uses OEM hardware - but it probably isn't the hardware you have on your E46 M3 right now.

Installation Notes

Professional installation is recommended. You'll need a body shop to paint & fit them according to your car's condition.
