LOW DRAG COUPE

With only 1 ever made, this is the only way you can ever experience the wild Low Drag Coupe of 1964. With its unique, all alloy hardtop body and serious mechanical specification, owning one of our Low Drag Coupe recreations is special indeed. We offer a range of different options allowing you to create your own special version.

We have suitable donor cars available or you can supply your own. We can build you the car of your dreams, so please email Gavin for a fixed price to build you your very own Low Drag Coupe.

PRODUCTION CAR SPECIFICATIONS

BODY

The unique body shape of the Low Drag Coupe has been replicated before, sometimes well and other times not so well! For us to make sure we build our bodies to the correct profile of the original, we purchased our first body from Simon Dunford in the UK. Simon has the buck made from the original car when it was restored so we can be certain the shape is correct. We had this first body 3D scanned and our own body forming buck made from that so we could then make our own totally accurate bodies in house.

The body of a Low Drag Coupe is made totally from scratch in aluminium. We have imported a specific grade of aluminium sheet from the USA and we also import our rivets from an Aircraft manufacturer in the USA. The body structure is built up on our specially built alignment jig using the factory E Type dimensions. The front frames are built new and upgraded to handle the extra stress and extra s strengthening and upgrades are also strategically incorporated into the structure to avoid fatigue – something Jaguar were not concerned about in the original car.

The bonnet used on the Low Drag is quite different to a production E Type bonnet as is of course the rest of the outer panels – rear guards, doors, bootlid and roof. But there are also a host of unique features in the rest of the Low Drag body from the bootfloor, the firewall, the transmission tunnel and the inner rear quarter panels. New unique door frames and Perspex windows and the special Low Drag front and rear windscreens are included.

The body is then painted in the colour choice. The internal panelling can be painted to match or left aluminium.

ENGINE

Mechanically both the Low Drag coupe and the Lightweight E Type are the same. There are numerous engine specifications that can be requested and certainly not limited to the below range. The engine specification is discussed at length and tailored to your needs but these are typical specifications that can form a basis for comparision. All engines are fitted with brand new alloy bodies water pumps, engine oil cooler with braided lines and our lightweight alternator conversion with micro V belt pulleys.

Stage 1: Rebuild the original donor 3.8 or 4.2 litre engine with electronic ignition, conversion to unleaded, triple 45DCOE webers and our tuned length extractor and exhaust system. Alloy flywheel and diaphragm clutch. Typical 250hp.

Stage 2: As above but with forged pistons, big valves, CNC head porting, reground camshafts. Typical 320hp.

Stage 3: Replica wide angle cylinder head with correct vented cam covers 48DCOE webers. Custom forged pistons to suit wide angle head. Upgraded tuned extractor and exhaust system. Typical 350hp.

Stage 4: As above but with full alloy block 3.8 litre only. Typical 350hp but 45kg lighter.

Stage 5: As above with complete replica dry sump system. This is now typical of the engine that was fitted to the Low Drag Coupe.

Engine Options

Engine Options from here include butterfly injection, slide throttle injection, throttle body ECU controlled electronic injection, Carrillo conrods, long conrod/short piston combinations. Development of a stage 3, 4 or 5 engine for racing can approach 400hp. FIA compliant specification for racing also no problem. The engine specification can be discussed in detail and priced up accordingly.

GEARBOX

The original Low Drag Coupe and Lightweight E Type’s used either the original Jaguar 4 speed or ZF 5 speed gearbox. In our standard spec, and FIA race spec car, we rebuild the donor 4 speed. Alternatively we can supply a rebuild Jaguar 4 speed or supply the optional alloy cased 5 speed gearbox that we fit to our road E Type’s. These are designed specifically for the E Type, they use the E Type bellhousing, mounting and tailshaft and the selector is in exactly the right position. They use redesigned T5 gears and a cast alloy casing that looks very similar to a Jaguar casing.

DIFFERENTIAL

In our standard spec car we rebuild the donor differential which will be LSD from an E Type. From there we can tailor the ratio to the intended use of the car (and the gearbox) by replacing the crownwheel and pinion. In the majority of cars we build or restore we install a Quaife torque biasing differential centre which replaces the original LSD unit. These are far superior to the original Jaguar LSD. We can also build the differential in an alloy or magnesium housing for maximum weight reduction (not FIA approved). For carswith racing intentions, we incorporate an optional differential oil cooler as per the factory race cars.

SUSPENSION & STEERING

The front suspension from the donor car is dismantled, checked, zinc plated and then rebuilt with new poly bushes, ball joints, eccentric camber/castor top fulcrum shaft as per the factory cars, uprated torsion bars, adjustable shock absorbers and bigger (spec dependant on use intentions) front swaybar. We fit a brand new quick ratio steering rack which is solidly mounted to the front frames. The donor steering column is restored. The donor rear suspension is dismantled, checked, bead blasted and painted. All new bearings, universal joints and uprated bushings are fitted with adjustable shocks with adjustable spring platforms and uprated coil springs are fitted. New peg drive hubs are fitted front and rear. Suspension options include aluminium bodies double adjustable GAZ shocks and the swaybars are tailored to the driving intentions of the car.

BRAKES

The donor pedal box is retained and restored with new master cylinders fitted. The standard original E Type brakes will not be sufficient for the performance capabilited of these cars, even though it will be some 300kg lighter than a standard E Type.

System 1: FIA approved MKIX callipers and solid rotors are fitted to cars that are to be raced. These use brand new cast calliper mountings and brand new uprated billet alloy calliper cylinders and custom brake pads. Cooling ducts as per the factory cars are fitted front and rear.

System 2: Vented front and rear disc rotors fitted with Alloy racing callipers at the front and rear. Cooling ducts as per the factory cars are fitted front and rear.

WHEELS & TYRES

15 inch replica peg drive cast Magnesium wheels are fitted front and rear, the size of which is dependent on the rear wheel arches. Low Drag Coupes and wide rear winged LWT E Type’s use 7 inch front and 9 inch rear. Tyres are Dunlop racing tyres, size dependant on wheel width.

INTERIOR

The interior features replica bucket seats and new dash boards made from aluminium. The standard trimming is black leather for the seats, black vinyl for the door trims and sill covers and bound black carpets. The dash facias are remade in aluminium and then black vacuum moulded as per original. Trim colours and specifications are at the owner’s discretion. The original instruments are restored to Low Drag specification and a new braided wiring loom is installed.

FITTINGS

A replica alloy radiator with alloy header tank and mounting bracket is fitted and a replica alloy fuel tank with quick fill cap as per the factory cars. Fuel system is determined by the induction used (Webers or injection). New Lucas Le Mans headlamps are fitted along with new front and rear lamp assemblies. New handles throughout and Perspex headlamp covers, bug deflector and sill extensions.
