Ford GT40

Ford GT40 continuation collectible is licensed and endorsed by Safir GT40 Spares LLC, as a true “continuation” of the original. Each hand crafted GT40 carries the GT40 -P chassis number and is registry eligible. The versions that are currently offered are the MK1 or MK11 “A” and “B” body styles, available in right or left hand drive, and have a curb weight of 2400 lbs.
The chassis is an exact replication of the original monococque unibody structure down to the press steel roof spider. The only departure is the use of electro-galvanized sheet steel in the construction. The chassis, at over 12,000 pounds per degree is stiffer than any other chassis on the market, and is made up of over 244 laser cut and bent or pressed parts.
The suspension features the original race car lay out. So original are the GT40 continuation models that two thirds or the parts are interchangeable with an original.
The GT40 continuation accurately replicates the original chassis, suspension, wheel hubs, uprights, pedal box, instruments, steering, dash, “bundle of snakes” headers, catches and latches to name a but a few.
Automobile owners also have the luxury of modern safety modifications such Wilwood super light brakes, Bilstein shocks with H& R springs, an adjustable pedal box, cross flow radiator. Air conditioning which has been added with the compressor unit cleverly disguised in a mock up dry sump placed in the original position.

A center shifter is standard but the continuation GT40 may be ordered with an original style sill shifter available for right hand drive models. IF you have a left hand drive continuation GT40 you may want to opt for a modified sill shifter which is cable driven.
The Continuation GT40 is 163 inches long, 40 inches high with a ground clearance of 4″. The GT40 continuation is 70 inches wide. The track front and rear are both 57 inches with a 95 inch wheelbase. The GT40 continuation has dual “Monza” style gas fillers and a 22.5 gallon fuel tank.
The interior features original style seats and racing 4 point harness seat belts. The GT40 continuation will comfortably fit a 95 percentile driver (6’2″ X 240 lbs) by removing the seat “trampoline” support. A Racing style dash features Smith Gauges. The GT40 continuation has Rack and Pinion steering and has been fitted with a removable steering wheel for easy access to the cockpit.
We offer the following wheel options on the MKI: The standard MK1 BRM style rims are 10″ wide in the rear. Available on special order are the MKI BRM style 8″ rims or the wide body 13″ rims. The spare wheel access cover can be ordered in a single or dual opening type.
The GT40 continuation leaves the factory as complete rolling chassis, complete in every way except for the engine, clutch, and transaxle.
The recommended power source is a specially prepared Roush engine with the new RBT/ZF style 5-speed transaxle but owners also have the option to fit a Ford-based 289, 302, or 351W small block or 427 big block (MKII only) engine.
*Our GT-40 chassis uses ZE 50/50 a Zinc coated mildsteel steel(Electro Galvanized Steel) this ensures that our Chassis stand the test of time against rust and other harmful pollutants.
