PRB's latest model is an evolution of the PRB S2, which in later models used aluminum honeycomb to reinforce a traditional-style steel tube frame. The new chassis is 4 inches wider to accommodate taller and wider drivers, with a wider engine bay that fits modern emission-compliant engines and transmissions (engines currently catered for are the Mazda Duratec 2-litre and the S2000 Honda engine).
The new Widebody is a completely new design using new running gear and suspension geometry built specifically for race track performance. The new suspension has been designed by Peter Eppel, the suspension designer of PRB S2, S2 widetrack and PRB composite models. The new Widebody has an ultra-wide track for optimum on-track performance. The new upright design has allowed for long wishbones which provide a swing-axle length almost double that of the PRB S2, and allows precision positioning of roll centres.
Rear suspension is now exclusively independent and fully adjustable. The differential/LSD unit, halfshafts and uprights are sourced from a recent model Subaru and can be purchased brand new, or second hand units can be used from recent model cars. A wide range of ratios and LSD's are available.
Front suspension is a wide-track evolution of the PRB composite front suspension. It retains the outboard damper design of the S2 repositioned in a rising-rate configuration. Mazda MX5 uprights are used and are stronger and surprisingly lighter than alloy uprights that PRB have used in other models. The Mazda spindles use a sealed bearing cartridge providing a stronger, and much more accurate bearing than cup and cone bearings. They also retain clearances over the full range of operating temperatures.
The Widebody is sold only as a build-it-yourself kit for owner assembly, or if required assembly services will be provided by your PRB agent.
Due to a full Order Book, no new orders will be taken for the new Widebody until 2009. Please contact the PRB Agents shown on this website for details of how to register your interest for a 2009 kit.Westfield is one of the worlds largest manufacturers of clubman Sportscars, and have been in business for over 25 years and currently produce over 400 cars per year. In much the same way as the PRB design has developed, the UK-sourced Westfield chassis design has evolved significantly from it original form. The Westfield chassis accommodates todays drivers, and emissions-compliant engines in a rigid yet lightweight chassis.
The Westfield range of cars (SE, SEi, and Sport 2000) is sold in component kit form and is targeted at the owner who wishes to construct a high quality road or race clubman at the most affordable price. The cars are available in a live rear axle or fully independent rear suspension configuration, with the comprehensive kits starting at $11,350 inc GST.
In addition, other vehicles in the Westfield range such as the XI and the exciting, racetrack XTR2/4 can be ordered from the UK, although they are not a stocked item in this country. These cars are for track use only as it is very unlikely that they can be registered locally.
A key advantage of the Westfield kits is that they are finished in high-quality coloured gel-coat, meaning that no painting is needed which can save up to $3000 on the total cost of a completed car.
The engine options include the Nissan SR20, Honda S2000, Ford/Mazda Duratec or Toyota 4A-GE 20 valve powerplants.
Westfield kits are available ex-stock in a variety of colours and configurations, so as a builder you can be up and running in the shortest possible time.
