Product Details
If you're looking to get the most out of your BMW's suspension, these adjustable front caster rod bushings from SPL Parts are a solid option. They replace the stock rubber bushings with low-friction, articulating spherical bearings. This eliminates deflection in the caster rod under load, which helps maintain your suspension geometry for improved braking and more direct handling feedback. They are made in the USA and sold as a pair.
These bushings use massive 1-inch FK Racing Bearings with self-lubricating Teflon liners, built for performance and durability. The CNC-machined offset spacers allow for up to +/- 4 degrees of caster adjustment, giving you the ability to fine-tune your alignment. While these replace the bushings, they do not include the OEM arms themselves. This kit is designed to fit a wide range of BMW 2, 3, and 4 Series models from 2012 onwards, including popular examples like the F30 328i and F32 428i.
