Performance Upgrade for the BMW 335i E93

Get the most out of your BMW 335i E93 with precision wheel fitment from DKU Performance. The Central Bore (C.B.) is a vital component that keeps the wheels perfectly centred on the hub, ensuring smooth operation, reduced vibration, and long-term stability for your 335i E93.

Precision Engineering & Exact Centering

The C.B. is a machined aperture on the rear of each wheel, carefully cut to fit the hub so the wheel sits correctly when the lug nuts are torqued down. On a performance car like the BMW E93 335i, this precision matters — exact centering on the hub dramatically reduces the likelihood of vibration through the steering and chassis.

Model-Specific Fit & Centring Ring System

Some wheels are manufactured with a bore matched to a single vehicle type, making them model-specific. For wheels designed to fit a variety of cars, a centring ring system reduces the bore size to match the hub correctly, ensuring the wheel is true on the hub rather than held only by the lug bolts.
