Viele neue Carbonteile und Aufladung für den Original-Vierzylinder

Jeder, der sich ein bisschen für Sportwagen oder Youngtimer interessiert, weiß, dass die erste Generation des BMW M3 zu DEN Klassikern schlechthin gehört und sich innerhalb der letzten Jahre zu einem absurd teuren Luxusgut entwickelt hat. Wie so oft ist Originalität noch immer die beste Basis für Mondpreise auf dem Gebrauchtwagenmarkt. Umso besser sollte man sich überlegen, ob man seinen E30 M3 wirklich zur Optimierung frei geben möchte, auch wenn sogenannte Restomods (die Verbindung von Restaurierung und Modifizierung) aktuell der letzte Schrei in der Szene sind. Die neueste Neuer- und Bessermachung eines verehrten Klassikers stammt von der Firma Redux aus Großbritannien. 30 alte M3 möchte man insgesamt umbauen. Das erste Exemplar wurde nun an einen Kunden in Kalifornien ausgeliefert. 

Redux stellt seine Arbeit unter das Motto "Enhance. Evolve.", was so viel bedeutet wie "verbessern und sich entwickeln". Im Falle des E30 M3 vertraut man dort nicht wie oft gesehen auf einen Sechs-, Acht- oder gar Zehnzylinder-Umbau, sondern behält den 2,3-Liter-Vierzylinder bei. Die Nutzung des S14-Motors war laut Redux "nicht verhandelbar". Eine Hubraumvergrößerung auf 2,5 Liter ist bei allen Umbauten obligatorisch. Genau wie spezielle Kolben, Pleuel und eine BMW-Motorsport-Kurbelwelle.

Wer möchte, kann darüber hinaus eine Aufladung per Turbo ordern. Der Empfänger des ersten Autos entschied sich für die große Lösung. Bei einem Ladedruck von 1,0 bar bringt das Aggregat nun 390 PS und 529 Newtonmeter Drehmoment. Die Kraftübertragung erfolgt über eine verstärkte Variante des originalen Sechsgang-Getriebes mit neuer Schwungscheibe und einer stärkeren Zwei-Scheiben-Kupplung. Dazu kommen ein optimiertes Hinterachs-Sperrdifferenzial und stärkere Antriebswellen. Später will Redux auch ein kürzer übersetztes Fünfgang-Getriebe anbieten. 

Im Fahrwerksbereich optimiert man den M3 mit einem EXE-TC Competition-Fahrwerk samt dreifach verstellbarer Dämpfer sowie einer AP-Racing-Bremsanlage mit Sechs-Kolben-Sätteln vorne und Vier-Kolben-Sätteln hinten. Auch hier soll es zu einem späteren Zeitpunkt Verbesserung in Form einer Carbon-Keramik-Bremse geben. In den Radhäusern drehen sich Cinel DTM Monoblock-Alus mit Michelin-Sport-Reifen. 

Wie Sie auf den Bildern sehen können, hat die Karosserie des Redux E30 M3 einen sehr cleanen, originalen Look. Die Spenderfahrzeuge, bei deren Auswahl Redux seine Hilfe anbietet, werden sandgestrahlt. Sollten Schwachstellen zu Tage treten, werden diese beseitigt. Im Anschluss ersetzt das Unternehmen Schürzen, Kotflügel, Dach und Seitenschweller durch Teile aus Carbon. Optional wird es auch eine Kohlefaser-Motorhaube geben.  

Das Interieur versieht der Tuner mit haufenweise Alcantara und lederbezogenen Recaro-Schalensitzen. Die Rückbank fliegt raus. Der Golfball-Schaltknauf ist nicht (!) aus einem Golf GTI, sonder stammt von BMW Motorsport. Außerdem kriegt der Kunde stehende Pedale von AP Racing. 

Ein alles in allem ziemlich atemberaubender E30-M3-Umbau bei dem uns lediglich das digitale Instrumentendisplay (wie kann man nur die wunderbaren analogen Original-Instrumente entfernen?) sowie die etwas unseriösen DTM-Endrohre der neuen Edelstahl-Auspuffanlage stören würden. Den Preis für den Redux-M3-Restomod erfährt man auf Anfrage, was in der Regel nichts Gutes für den eigenen Geldbeutel bedeutet.

ANNOUNCING THE DELIVERY OF OUR FIRST CUSTOMER’S BMW E30 M3 | ENHANCED AND EVOLVED BY REDUX

·      Hand-built in the UK with a focus on performance upgrades and tasteful modifications using the highest quality components and inspired by BMW’s motorsport heritage

 

·      This is the first in a series of 30 vehicles, with the option of naturally aspirated or turbocharged re-engineered 4-cylinder, 2.5l S14 engine

 

·      The BMW E30 M3 | Enhanced and Evolved by Redux. Creating an even more engaging driving experience for fellow E30 M3 enthusiasts.

 

12th March 2019

 

Thermal, CA - Redux is delighted to announce the delivery of its first enhanced and evolved BMW E30 M3 to its owner in Southern California. The E30 M3 is the first in a limited edition series of 30 vehicles. All restorations will feature tasteful and high-quality upgrades including carbon fiber bodywork, an Alcantara, leather or cloth-trimmed interior (or combination of all three) tailored to each client, performance upgrades inspired by BMW’s motorsports heritage, and a choice of either naturally aspirated or turbocharged re-engineered 2.5l, S14 engines.

 

The idea for the BMW E30 M3 began as a personal project for CEO Simon Lord, but it soon became apparent that his vision could be something much bigger in scope and could be shared with other automotive enthusiasts. Since then Lord has set about building a team of like-minded BMW aficionados to turn that vision into a reality. The result is a fully restored and tastefully modified homage to the box-flared ‘young timer’ classic.

Enhance. Evolve
Each Redux restoration is based on the E30 generation of the BMW M3. While a standard E30 3 Series was considered as a donor, the M3 model was a necessity primarily for the Paul Rosche-designed 4-cylinder S14 engine, unique to the first generation M3.


 

In order to gain horsepower, many suggested the tried and tested method of swapping a BMW S54 6-cylinder, S65 V8 or even S85 V10; however, retaining the S14 engine was non-negotiable. As confirmed over dinner with an ex-E30 M3 racing legend, the naturally aspirated DTM-spec 2.5l S14 delivered 380hp with a red line of 10,000 rpm! However, this necessitated frequent rebuilds and was therefore not a viable option.

 

With the M10 block’s turbo heritage – i.e. the 1.5l ‘Megatron’ turbocharged, championship winning, F1 engine – Redux aimed to match the S14’s DTM performance figures using forced induction. This was the option chosen by the owner of the first vehicle, resulting in 390hp and 390lb/ft torque (at 1.0bar/14.5Psi boost).

 

Once the engine decision was made, the same logic was applied to the rest of the car with the goal of further developing the E30 M3 without moving too far away from the original: Enhance. Evolve.

Inspection and Strip Down

Each build starts with a thorough inspection of the vehicle, followed by a methodical removal of every component. Before undergoing a complete restoration, the shell’s paint is removed by media blasting. The rust damaged sections are repaired, mounting points fitted for new components, and a number of unique features created. (Whilst many of Redux’s customers will opt for a road car set up, a track-ready version with a half or full roll cage is available, as chosen by the first owner).

 

Drivetrain, Front End and Rear Assemblies

The engine is stripped down and re-engineered from 2.3l to 2.5l; custom connecting rods, pistons, and a BMW Motorsport crankshaft are fitted. Due to the forced induction engine’s high torque figure (390lb/ft), the gearbox is overhauled and a custom flywheel, and twin plate clutch fitted. The rear end features an upgraded differential, and heavy-duty custom drive shafts, along with a larger diameter, custom propshaft. Finishing off the underside is a hand-fabricated, steel exhaust system with rear silencers (as the first owner lives in California to conform to CARB emissions for road use, a center section can be swapped out on v-bands to fit the two catalytic converters).


 

Suspension

To compliment the upgraded drivetrain, EXE-TC Competition Suspension developed a set of bespoke 3-way dampers for the car. The UK-based company has a storied motorsports history, having assisted Sebastian Loeb in winning multiple World Rally Championships, claimed the Isle of Mann TT and Nürburgring 4-door saloon lap records in partnership with Prodrive and Subaru. Combined with the AP Racing 6-piston front calipers (330mm rotors) and 4-piston rear calipers (304mm rotors) the suspension behaves in an assured manner in all conditions.

 

Dry Build

Once the fabrication, engine, front end and rear assemblies, and custom parts are ready, the dry build begins. After all parts are test fitted and any final adjustments made, all components are removed again, and the shell thoroughly cleaned.

 

Paint

The shell is meticulously worked through to ensure all signs of fabrication are smoothed out. Once primed and block sanded, the painter applies a water-based, Glasurit 90 line paint scheme. Finally, progressively higher compounds of grit sandpaper remove any minor imperfections in the paint including textures in the clear coat (orange peel), runs or drips. This is all done by hand before polishing to a mirror finish.

 

Final Assembly and Interior Trim

With the shell painted, the drivetrain, front and rear assemblies, Raychem wiring looms, Motec hardware, and sound proofing material are refitted, all of which requires considerable patience and a very steady hand.

 

Although the cabin has a familiar look and feel, it features a considerable number of bespoke interior components. Redux’s first restoration will spend most of its life at a private members’ circuit in Southern California, so a full roll cage has been fitted in order to ensure the owner remains safe. The interior is tastefully trimmed in Alcantara and leather, and fitted with plush wool carpets. The A pillars, B pillars, front and rear door cards, and headliner are all heavily modified and re-trimmed in Alcantara, and the rear seats have been deleted and replaced with a removable rear bench. The trunk allows access to the battery, diff pump, fuel pump, swirl pot, and rear PDM via an Alcantara-trimmed drop down panel.
