Introducing our E30 Convertible Rear Euro Chrome Bumper End Caps, compatible with E30 cabrios that have a standard European early (pre-facelift) rear bumper. The passenger side is no longer available and the aftermarket alternatives on the market were not up to our standards, so we decided to make our own.
Product Details:
-
Our end caps use one main mounting bolt and two small screws to fasten them, just like the original convertible specific end caps.

Proudly Offered in three Finish variations to suit your needs:
1. FDM Printed, Unfinished: This style is made with a traditional 3D-Printer and layer lines are visible from close-up. Although optional, you can choose to hand sand and paint these yourself to achieve a smoother surface finish. This style is geared towards those who are on a budget and don't mind putting in a bit of work to make them perfect.
2. FDM Printed + Finishing: This style is made with a traditional 3D-Printer and layer lines are visible from very close-up, but from a distance you cannot tell that these are 3D printed. We hand sand the end caps smooth and finish them with two coats of SEM trim paint. This is the most cost-effective solution while still offering all the qualities of a high-quality replacement part.
3. Resin Printed + Finishing: This style is geared towards those who want the best. This finish provides all the qualities of an OEM+ part: we resin print your end cap(s) out of high strength engineering resin, wash and cure your part(s), hand sand the outer faces, and finish it off with two coats of SEM trim paint to match the black trim on your rear bumper. You will not be dissatisfied with this option: “this is what I personally run on my E30 😉” (words from Lars, Founder of Botter Manufacturing).

Hardware Add-On: Our end caps are fully compatible with OEM hardware if you still have yours (the speed nut and the M6 mounting bolt). But if you don’t, or you would simply like to replace it with new, we have you covered for a low cost.
