The acclaimed GTR is the latest model from Ultima and it embodies all that the company has achieved with its previous models, while incorporating a whole raft of exciting new features. Nothing on the GTR has been taken for granted and every area has been meticulously researched before dedicated components are either fabricated by the factory or sourced from specialist suppliers. Unlike many high performance cars, Ultima doesn't believe in the parts-bin mentality that sees components scavenged from other models. From designing and manufacturing its own wheels to having suspension specialist, Intrax, manufacture dampers specifically for the GTR, Ultima has striven to ensure there are no shortcuts when it comes to the quality of the end product.
To that end, here we've outlined just a few of the components we feel demonstrate the lengths to which the company has gone to deliver the ultimate driving experience.
» Developed over thousands of miles of road and track testing.
» Fully triangulated spaceframe, with integral crash protection crumple zones all round.
» Fully jigged to ensure total uniformity, including all mounting points for suspension etc.
» Integral rollcage welded to the main frame.
» Once fully checked, the chassis is grit-blasted, etch primed and powder-coated to form a smooth corrosion resistant finish.
ALLOY PANEL SET
» All aluminium panelling is supplied pre-cut to the exact shapes required.
» All bends pre-formed at the factory.
» Polythene coating on both sides minimises potential for scratches during assembly.
» 18-gauge mild steel, Tig welded for maximum strength and lightness.
» CDS pedal pivot bar ensures ultra smooth action.
» Pedal foot pads are adjustable for perfect driver comfort.
» Front/rear braking bias can be set either manually or via cockpit mounted adjuster wheel.
» Lightweight accelerator pedal specially designed for easy heal/toe operation.
» Dedicated master cylinders have been carefully balanced to the pedal ratio for optimum feel.
» Single fluid reservoir feeding both master cylinders features SVA approved fluid level warning system.
» Cold-drawn seamless tube is Tig welded for maximum strength with minimum distortion as well as visual appeal.
» Depending on end use, either urethane or nylatron bushes can be specified, while a fully rose-jointed set-up is available for those looking for the ultimate in precision and adjustability.
» Carefully designed suspension geometry ensures that, despite tyres which are 2-3 times the width of most road cars, there is no hint of bumpsteer or tramlining.
» Cast in LM25 alloy and heat treated to TX combine for maximum strength and lightness.
» CNC machined to accept specially spaced pre-loaded taper bearings.
SUSPENSION TOE LINK
» Hexagonal sleeve with rose joints at either end ensures easy adjustment and absolute precision of rear wheel toe in or out.
» Bespoke front hubs are machined from a solid billet of 24T steel for maximum strength.
» World renowned braking specialist, AP Racing, has designed the braking system for the Ultima GTR.
» Huge 320mm x 30mm curved vaned discs are cross-drilled.
» 4-pot alloy calipers incorporate a smaller leading piston diameter than the rear to reduce taper pad wear.
» Caliper piston sizes have been carefully balanced against the brake pedal mechanical advantage, weight of the car, diameter of the discs and rolling radius of the tyres.
» Separate pressure and dust seals make this set-up ideal for both road and track-day use.
» Manufactured from the best quality stainless steel braided hose.
» Lines come fully finished, with swaged ends to conform with TUV regulations.
» All lines are fully pressure tested by the manufacturer prior to dispatch.
» Lines are supplied coded to ease customer assembly.
» Alloy casing is specially designed and cast for Ultima by Titon.
» By starting with a clean sheet, the design of the rack can be exactly tailored for the car, positioning items such as the track rod ball joints in the ideal location and ensuring there is no bump steer yet plenty of vital feedback to the driver.
» Alloy locating blocks ensure no lateral movement of the rack once it is fitted to the chassis.
» Centrally positioned rack pinion allows for an angled steering column with two universal joints, thus ensuring no intrusion of the column into the cockpit in the event of a front end impact.
» 50mm crumplezone placed within the column immediately in front of the steering wheel to further enhance crash protection.
» Front mounted radiator, manufactured from brass and copper, becomes an excellent energy absorption component within the existing chassis crumplezone area.
» Standard radiator is designed to cool engines up to 750bhp.
» System has been designed to self-bleed and is a sealed system using a swirl pot and separate expansion tank located in the engine bay.
» Constructed from 20mm diameter CDS tube with hook joints for angle movement and precision located by rose-jointed supports.
» Gear lever can be positioned for either right or left hand gear changes regardless of driving configuration.
» Rod linkages help to maintain the excellent precision and feel of the Porsche transaxle.
» Constructed from alloy sheet which is welded and pressure tested prior to dispatch.
» Positioned within the Ultima spaceframe chassis for maximum driver/passenger protection.
» Filled with Safon reticulated polyurethane foam as an explosion suppresser and surge reducer.
» All fittings in 3/8" male to facilitate the use of stainless steel braided petrol hose fittings.
» Supplied with a dip tube sender unit in both tanks.
» Filler hose made for Ultima in wrapped nitrile rubber.
» Aircraft style filler cap with Ultima logo on release lever.
» The coil-over spring dampers have been specially designed, tested and manufactured by Intrax.
» Mono-tube construction with internal separation piston ensures accurate damping at all positions.
» Incorporates thermostatically controlled valves which give uniform damping at all times.
» Springs are made from the best race quality chrome silicon wire, protected from corrosion with silver powder-coating.
» Specially manufactured drive shafts are made in S155 steel more commonly found in Formula 1 cars.
» Half the weight of a conventional Ford unit and capable of taking up to 1000bhp.
» Joints at either end are Lobros ball type which bolt directly to the transaxle and hub flanges.
» Specially designed by Ultima and includes wiring for all the factory options.
» All connectors are pre-fitted, as is the relay section and fuse box.
» Front and rear detachable sub-looms ensure easy installation or later removal of engine cover or front bonnet.
GLASS AND LAMINATES
» Ultima laminated windscreen is a bespoke part carrying all the E and US approval markings.
» Side screens are also bespoke parts, made from shatterproof polycarbonate safety glazing.
» GTR wing is of double element design, made from carbon fibre.
» Fully wind tunnel tested at MIRA.
» Wing supports are CNC machined from solid 20mm billet alloy plate.
» Specially designed manifolds and silencers available in both stainless and mild steel.
» Tig welded to reduce distortion.
» Several silencing options available, including high-flow catalysed system.
» Specially designed seats provide total lateral support and have integral seat runners.
» Cover options are black leather or Alcantara.
» These specially designed wheels are actually assembled in-house to ensure a level of quality that is endemic of all the parts that go to make up a completed Ultima.
