The Cars of Unlimited Auto

BMW E36 V12 BiTurbo, 1,012 hp and 1,182 Nm

Eight years in the making, a bespoke widebody kit and a BMW V12 with twin-turbo charging: an independent dyno recorded 1,012 hp and 1,182 Nm at 2 bar of boost. This car is our calling card at shows and on the track.

BMW 328i E46 “PANDEM” Widebody

The E46 in PANDEM widebody form shows what a well-known wide-arch kit looks like when bodywork, wheel and tyre package and suspension are all matched with real consistency.

Lamborghini Countach Replica with BMW M73 V12 BiTurbo

A build in progress: a Countach replica powered by a twin-turbocharged BMW M73 V12. Bodywork, drivetrain and engineering all take shape here in Weiden. We post the progress regularly on Instagram.

BMW M6 E63 “21 Inch on AIR”

The M6 on damping-adjustable air suspension with 21-inch wheels stands for our chassis work: extreme stance, clean installation and still genuinely drivable.

DETAILS

The Skills Behind Our Projects

Engine Building & Forced Induction

Engine rebuilds, engine swaps and complete twin-turbo conversions including all the supporting hardware. Right up to four-figure power figures on the dyno.

Bodywork & Widebody

Fitting, welding, sealing and paint-prepping widened arches, for body kits and widebody conversions just as much as for bespoke one-off builds.

Suspension & Wheels

Air suspension, coilovers, race setups, wheel alignment and the calculation of rim widths and offsets for maximum stance with full clearance.

Approval & Road Legality

We prepare conversions so they can pass inspection and be entered in the vehicle documents by TÜV SÜD, from parts certification through to individual vehicle approval.

OVERVIEW

Why We Show This: Proof Instead of Promises

Anyone can claim they know how to build engines. We prefer to show measured numbers, documented build stages and cars you can walk up to and touch at events. Unlimited Auto has been seen at Tuning World Bodensee 2024 in Friedrichshafen, at Bimmerfest Europe and at AMTS in Budapest, and took 1st place at GRIP. Das Motorevent at the Nürburgring.

Exactly the same care goes into the everyday work: anyone who tunes a V12 to 2 bar of boost also does the brake inspection and the oil change properly. Servicing, maintenance and inspections as well as repairs for vehicles of all makes are carried out to manufacturer specifications, at Vohenstraußer Str. 5 in Weiden in der Oberpfalz.
