2000 BMW 323i

We started with a clean vehicle without any modifications, This vehicle came to us with electrical problems and decided not to pursue a repair.

Its a shame to remove the interior from a perfectly good car, but weight loss is key

Removing Interior

Interior fully removed

Removed all of the interior, seatbelts, airbags, gutted rear doors and fixed rear windows in position to allow removal of regulators and motors.

Trimmed and lightened Dash

Removed dashboard, trimmed and removed any unnecessary vents, glove box, dash airbags and wiring harness, radio and full audio system harness

Rebuilt Calipers

We changed to an extended stud vs. the standard lug bolt BMW uses. This allows for easier wheel changes and adding or removing wheel spacers with ease
