    Self Build Suffolk SS100 Jaguar

    The Suffolk SS100 is constructed by using a single Jaguar XJ6 Saloon 1968-1986 to provide all the major mechanical donor components. We typically provide a big boys Meccano set which would be everything we would provide to our team on the workshop floor to build the entire car, right down to the last nut and bolt - everything less the assembly. This allows the self-build candidates enjoy all the satisfaction and rewarding aspects of building a car themselves, without and of the associated hassle of a restoration, or having to attempt to build an incomplete car.

    Jaguar XJ6 donor cars provide all the major mechanical components and allows the customer a wide range of options within the chosen specification of their finished Suffolk SS100. A great many Jaguar XJ6 components are easily interchangable with other models. All donor cars supplied by ourselves come with a Jaguar Sports V5C registration document. We can tailor any of a range of parts to suit your build requirements and desires, 3.4, 3.8 or 4.2 litre engines, Jaguar 4 speed overdrive gearboxes, aftermarket 5-speed gearboxes and automatic transmissions are all easily specified.

    Construction and Building Procedures

    Our Customer Build Manual fully explains all assembly procedures. The Build Manual is updated annually so the information you are getting is always right up to date.

    The customer self-build programme can be  set up and modified to suit your individual requirements.

    First Delivery:

    We would typically prepare all items to enable the '4 corners' of a chassis to be assembled. This would include powder coated chassis plus all brakes, suspension, steering, front and rear hubs plus a pre-assembed rear axle assembly, fuel tank, radiator hoop and stays.

    Second Delivery:

    You would receive the reconditioned XK engine, gearbox, overdrive, propshaft, SU carburettors and inlet manifold, stainless steel exhaust system, radiator and road wheels.

    Third Delivery:

    You would receive the prepared body (can be supplied painted) and a large number of assembly parts including pre-cut floorboards, wiring loom and ancillaries.

    Fourth Delivery:

    Would comprise the windscreen, hood frame, weather gear, seats, interior, brightwork, lamp bar, headlamps and final components.

    All deliveries are at customers calling; there is no prescribed timescale, and we have had some customers who have completed their assembly in as little as 6 months whereas some have taken over 2 years when choosing to do it as a slow and steady project.

    13. Install 2 front brake flexi hoses between brake lines and calipers.
    14. Fit fuel tank, contents sender unit and fuel pump to chassis.
    15. Fit 5/16 copper fuel line to chassis (leading from tank to offside of engine compartment) with 7 clips.
    16. Fit engine mountings

    Ordering a Car in Component Form

    Orders would typically be placed following a visit to our workshops to learn more about the cars, and have a demonstration on the road. You can then also meet the team and see the parts being manufactured and works cars being assembled.

    Typically, we would ask for a part payment of £2,500 to begin the order, and then 4-8 weeks depending on our current order schedule, to have the first shipment ready for delivery. The balance of this initial order would then be payable once these parts are ready for dispatch from Suffolk Sportscars.

    With regard to the next shipments, we would never chase you or have a schedule for the speed at which you build your car. We allow you to dictate to us how many items of our comprehensive parts list you require and the schedules for parts shipments you request.

    On previous occasions, we have sent entire cars, less the assembly in crates when doing long distance orders. We currently have customers in the Philippines and in India building cars, and have also sold to America, Australia, New Zealand and Europe.

    The range of parts listed above are dedicated to the production of the Suffolk SS100 Jaguar.

    In addition to the above list, a number of minor parts can be sourced from the donor Jaguar XJ6. We can provide these in a fully reconditioned and as-new state, or provide you with a set to recondition yourself.
    The remainder of the parts and all fittings would typically supplied by us, or purchased independently by the customer. We can supply all the parts required for the complete assembly of the car. Full and complete price lists are available upon visitation of our Woodbridge workshops.

    Partial assembly of the chassis, painting, trimming and workshop services are also available.

    We can supply the Suffolk SS100 partially built and will be pleased to quote for specific requirements.

    The chassis, component packages, engine and bodywork are usually delivered by our own staff and transport. Smaller deliveries will be sent by carrier. The chassis and the main bodywork unit can be carried by two strong men. The engine requires an engine crane, which we can bring with us when we deliver to you.

    Registration of the Suffolk SS100

    INF 26

    A number of Suffolk SS100 cars have been constructed under the Rules laid down in Booklet INF 26, issued by the Department of Transport. The Suffolk SS100 qualifies as a conversion because the car uses the brakes, suspension, steering, engine and gearbox from a single donor Jaguar XJ6. The donor car is over 10 years old. The new chassis is specifically designed and constructed to accept the components itemised above. Completed cars would require a new, current MOT certificate upon completion and an annual MOT test thereafter. This enables the car to carry a period registration from the age of the donor vehicle.

    I.V.A. (Individual Vehicle Approval)

    Cars built for use in the United Kingdom require an I.V.A. Test after completion.

    The test has been successfully applied to a large number of Suffolk cars, which has passed all the I.V.A requirements. Cars that have passed the I.V.A. test are given the latest V5C Registration Document, showing the car as new. This means it can be assigned with a new registration, and no Q plate. For example, a 2017 Suffolk SS100 would wear a number such as "AV17 ABC" when registered, and would then be able to have a classic registration number e.g. "SSL 519" transferred onto it in the same way one would transfer onto any car. Black and silver classic show plates are also available.

    However, because the Suffolk SS100 uses an engine designed 30+ years ago, there are no onerous emission rules, and the car does not require a catalytic converter.

    Overseas Export Sales

    A large number of our cars are built and sold overseas. We are happy to crate and ship worldwide. You can also build the Suffolk SS100 using some donor parts sourced from the 1964-1969 Jaguar S-Type and Jaguar 420 models, which give the rebuilt cars an early date of manufacture. We have extensive stocks of Jaguar XJ6 parts to make up a customer's component requirements .

    Additional Information

    An online Build Manual is available free of charge online and you will find many useful pictures in our photo gallery on this website. The Bound Build Manual is 114 pages and fully explains all assembly procedures, this book is £20.

    The Trac SS100 Jaguar was born in 1990 and the principal design was by Terry Rowing. Roger Williams took over the project completely and the car became the Suffolk SS100 in August 1995. The car has been in continuous production since 1990. To date over 300 cars have been sold all over the world and we are currently busier than we have ever been.

    However, production is now deliberately limited, and will always remain so. Every new chassis is built to the specific order from a customer.

    We do not carry unsold new stock of chassis, bodies or completed new cars. The Suffolk Sportscars company commenced production at a small factory in Bury St Edmunds in 1996 .Having outgrown the premises we  moved to our larger 7500 sq. ft. facility near Woodbridge. This is now being doubled in size to provide additional production space.

    If you wish me to provide references from previous customers, I will be pleased to do so. The Suffolk SS100 is virtually all hand built and therefore labour intensive. Input prices are rising all the time and inevitably have to be passed on. Increases though, help to underpin the long-term future value of the car you build and own. I am always willing to buy back our cars, and can demonstrate that depreciation is certainly not a factor to be worried about with a Suffolk SS100 Jaguar.

    Cars have been built by customers all over the world. We have shipped component packages to almost all countries of Europe plus the USA , Canada, New Zealand, South Africa, Malaysia, India and Australia.

    We also have cars on the small islands of Madiera, British Virgin Islands, Bermuda, Isle of Man and the Channel Islands.

    We look forward to discussing your project with you soon.

    We always try to carry a stock of the best Suffolk cars and other classic Jaguar cars. All vehicles come fully works prepared and serviced, and ready for use.

    Over 190 cars have already been built by our customers all over the world. Join those who have had a great time building their dream car at home.

    We always have new cars being manufactured to order and built at our Woodbridge workshops. Come and see us to learn more about our cars.
