Simon.Rogers Posted March 25 Share Posted March 25 2008 Caterham Sigma Supersport iRS (Independent Rear Suspension) A super rare opportunity to purchase our demonstration iRS 7. The car is fitted with our unique independent rear suspension system. The de Dion tube is a thing of the past. All the benefits of the CSR chassis compliance yet retaining the very nimble narrow chassis of the S3. This car began life as an academy car. When I purchased this as my basis for the development of the iRS we always knew it was going to be a full refurbishment. A complete skin off refurbishment in 2021 all completed at Arch Motors. We then proceeded to fit the iRS kit along with way too many extras. This car had to be special yet very drivable and not extreme. Nearly all of these parts were new in 2022 Sigma 1.6 Supersport spec. MBE 9A4 - new 2022 - unlocked and mapped by Steve Greenald. CORE 1 way dampers - Digressive front pistons. Hyperco Springs Titan (just fully serviced and rebuilt) LSD - 3.92 Ford Standard brakes - Mintex 1144 pads front and rear Mix of copper and braided break lines Brand new Caterham 8 spoke wheels 6” and 8” ZZS tyres Carbon Carbon Carbon Dashboard Front wings Rear wings Excellent condition Leather Seats Caterham 4 point harness Lowered floors both sides FIA Roll bar Wrapped in 3M Crayon Grey with orange stripes New fuel pump and sender 5 speed Range of new dials and gauges Go Race quick release New CAT New Caterham polished silencer No heater Soft Bits half hood Doors New boot cover Just serviced and comes with MOT The iRS installation retains all standard brakes, dampers and drive shafts and is therefore reversible if ever wanted. Once you drive this car and experience the benefits of the system you won’t want to ever return and remain one of the growing fleet of cars. Please add up the cost of all the extras and add them to the base price of a comparable Supersport and you will see how much of a bargain this car represents. Private Sale £23,500.00 Note Tillets fitted in the pic below. 07920 843146 Link to comment Share on other sites More sharing options...
Ralph45 Posted March 25 Share Posted March 25 I remember seeing this at the PGM open day. An amazing looking car and beautifully engineered, super nice and if I was in the market for a new 7 this would be it. For those that are un- young enough to remember the advertisments……….. if Carlsberg did Caterhams ! 1 Link to comment Share on other sites More sharing options...

BenF Posted March 27 Share Posted March 27 If you are after an S3 chassis car, this is a much better bet than a DeDion car (speaking as someone who has a CSR). Especially considering the dreadful state of UK roads. 1 Link to comment Share on other sites More sharing options...
