Caterham S3 and SV iRS (Independent Rear Suspension) Conversions
Experience the Ultimate Caterham conversion. What everyone has always wanted. The comfort of the CSR in the light and nimble S3 chassis. Alternatively, upgrade the SV chassis to the iRS. We can now offer the conversion of your existing S3 or SV chassis to fully independent double-wishbone specification.
This is cleverly done as we retain the standard rear suspension dampers (of course we can offer upgrades to the OE dampers additionally). Retain the standard fuel tank, driveshafts, differential and brakes. We can offer an improved rear calliper if wanted at an additional cost.
Although we remove a very small section of the lower chassis rail that in the standard car attaches to the lower basket this could be reversed in the future if wanted very easily.
We prefabricate a rear “basket”, wishbones and upright which is then welded onto the rear bulkhead.
Our target for the conversion is 1 week.
The iRS makes for vastly improved road manners, particularly over sharp high speed surfaces. Of course, there is still a “bump” – these are small lightweight cars after all but the harsh sharp edge that we all “brace” for is removed.
Please call us for more details.
Our demonstrator Sigma Supersport is available for customers to test drive so you can really feel the difference before you agree to the change.
The cost of this conversion is £5950.00 + vat However for the first 10 conversions we are reducing this price to just £4950.00 + vat. Interest in this conversion is high so be quick!
