Technical Specifications
Fraser Clubman Specification
The Fraser Clubman chassis is made from 16 gauge ERW steel tube, they are constructed on a chassis jig for accuracy and then moved to a flat bed welding jig where the chassis are then brazed up. The chassis are all brazed up on a flat bed to maintain there dimensions once removed from the jig. A higher strength brazing rod is used around all of the critical suspension areas and other pickups.
Fraser Cars use brazing over MIG welding because it is a slow heat in and out process, the parent metals are not melted, therefore inducing less stress into the chassis with the brazing. This is not the quickest method of welding, but you end up with a far superior feeling and constructed chassis, with the chassis been able to take the rigours of hard race use without developing stress cracks or distorting.
MIG welding is a much quicker process to weld up a chassis, but Fraser Cars don’t believe in taking short cuts with what forms the basis of a good handling car.
The Fraser suspension is all time proven and tested and also has LVVTA approval, so that when it comes to making your car road legal you will have no problems with the design or manufacture. The front suspension components are made from a higher grade CDS tube. All Fraser suspension is TIG welded for the ultimate in finish and strength.
The Fraser suspension and chassis are well designed and tested. Fraser Cars were the first Lotus 7 replica manufacturer to introduce an Inboard front suspension system to these types of cars and our De dion rear suspension is second to none.
The Fraser chassis has undergone a huge amount of development from the original Lotus 7 design, with the cars now being stiffer, providing better feedback to the driver and are also safer.
The advantages of the Inboard front suspension is a reduction in unsprung weight, a great sprung/unsprung ratio, cleaner looking lines, easy adjustment of ride height without adjusting spring pre load, a shock that is effective through out the complete range of suspension travel.
The advantages of the De dion rear suspension is reduced unsprung weight, great sprung/unsprung ratio, narrower tunnel equals wider cockpit, glove box for extra storage, disc brakes as standard.
Both our De dion and Inboard suspension options are well proven with over 17 years (the company has been building Frasers for 21 years) of competitive use and also touring use. There are touring cars with over 120,000 km of use.
Fraser Clubmans have a long and proven race history weather it be on the track in sprint or endurance meetings or tarmac road rallies.

Pedal Box
Fraser Cars own with new and improved pedal box ratio. Fraser Cars have released an all new pedal box with a much improved pedal ratio.
Feedback from drivers was that the brake and clutch pedals often have quite high pedal pressure. This was to do with the lack of height that a Lotus 7 pedal box has. But Fraser Cars now have a solution, with a bit of engineering and a more clever use of space we have now managed to improve our pedal ratio by 16.5% this has allowed for a more progressive lighter brake pedal and a softer clutch that is kinder to the ball of your foot.
Fraser Cars have tested the new ratio in the white demo car and everyone was very impressed with the new pedal feel. This pedal box will now become standard on all Fraser Clubmans. Fraser Cars are also now working on a replacement set of pedals for existing cars.
