Chassis Specification Explained
A chassis is a steel tubular strong frame which the engine, suspension and body work are mounted to. If the frame is not structurally strong then it stands more chance of twisting and distorting. This then transfers through to everything that is mounted to the frame ie suspension, engine and bodywork. The quality of the steel used is critical and finding the right balance between lightness and strength is what makes or breaks a chassis

Which Suits my Requirements Best?
For Road use your best option would be the SB5 chassis as used in our Self Build Models, RR140 /RR190 Raptor models. If you are using your own engine we would advise using a power plant with less than 200 bhp /185 lbft torque.
For Road and Track Day use your best option would be the UHP-2 chassis as used in all our other RR models.
For Motorsport application your best option would be the UHP-3 , as use in a CS models
High tensile Raptor box section is on the right, which has approximately 40% greater tensile strength than the thin wall tubing on the left. This gives us an exceptionally strong and rigid base in which to build a sports car chassis and suspension system.
With the correct metal preparation ie bead blasting before powder coating, the chassis will last significantly longer than the thin wall chassis.
All our front suspension sub-frames are fabricated in their own bespoke Jigs. These jigs provide accuracy and ensure that all the sub-components are identical.
All our Chassis are built on site in our bespoke chassis jigs. All the material we use is certified and assembled by our team of highly skilled coded welders.
Fixings for wiring looms, mounts and brake pipe supports have all be painstakingly welded onto the chassis. Not only does this save build time but reduces the need to drill the chassis which does reduce it strength and potentially allows a path for ingress of water.
Light Weight Option Or Raptor Tubing ?
Our award winning chassis incorporates a very clever "through bolt" designed for the lower wishbones and front rocker assemblies to cope with the high corner loads.
