Race: Caterham Upgrades

Our approach to upgrades recognises that there is more involved than just replacement of old parts with new. We renew all relevant parts, not just the parts being upgraded, and always use new fasteners for reasons of safety; this approach also ensures an “as new” look to the upgraded race car. In addition your Caterham will be set-up to our race-proven settings optimised for road, track or race. We can manage the complete upgrade process including those mandatory upgrades which have to be carried out by Caterham.

Road, Track or Race

Many of the Caterham race upgrades can be used for fast road or track day cars. These upgrades are race-proven as to both the benefits and reliability of the components. Examples of upgrades suitable for road or track-day usage cover all aspects ranging from ride & handling to engine power upgrades.

Ride & Handling Brakes Power
Rear anti-roll bar Brake bias valve SADEV sequential gearbox
Alternative front anti-roll bars Mintex or Pagid pads Sigma 310R Upgrade
Supersport or 420R race springs & dampers Braided brake hoses Caterham Stage 1/Stage 2 for Duratec
Brake pedal modification to improve braking feel 420R race cooling package

Optimise On-Track Handling - Get your Caterham Set-up to our Championship Winning Standards

All of the Caterham race upgrades result in a significant change to weight of the car, weight distribution and ride height. As a result, fitting new parts is only the first step in the upgrade process. Subsequent to fitting new components it is essential that your Caterham has a race focused set-up so that you get the full handling benefits from the new configuration.

Eliminate Performance Limiters - Sigma Engine Diagnostics

Sigma engines are only available from Caterham on a sealed basis which rules out any option for external parties to rebuild or refresh components. Recognising the growing importance of the Sigma engined Caterhams, we have invested in engine diagnostics equipment that includes the ability to inspect the engine internals. As part of the DPR upgrade process we can check that your engine is delivering the required power. Using our Sigma engine diagnostics capability we will perform an engine health check to ensure that performance is not being impacted by sensor faults, poor compression or other potential performance limiters.

We also recommend installation of the Caterham dual breather catch-tank option for the Sigma engine; this is a worthwhile upgrade for road, track or race use.

Gain Competitive Edge - Improve Lap Times by Stopping Faster

The use of sealed engines ensures that there is nothing that can be done to gain a competitive edge from increased power. Driver coaching aligned with race car set-up should be the priority but taking steps to gain competitive advantage through improved braking is another aspect to consider. Fitting a brake bias valve will allow the car’s brake front/rear balance to be adjusted on-track to suit a particular circuit or changing conditions from dry to wet. If you find that your unloaded front wheels lock up on a greasy corner the brake bias valve will allow braking force to be transferred to the rear until the braking becomes more balanced. We can also advise on alternative pad materials that can significantly improve the car’s braking performance.
