    Caterham iRS #1

    in For Sale

    Posted

    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

    Transport 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

    Tillet B6 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.

    Do check for a twist in the lower steering column.

    You would be surprised how easy it is to twist it a little.

    SO get it checked for alignment and you should be able to see if your corrections have missaligned the front wheels.

    If the column has twisted then both wheels will have been offset to one side.  Then your alignment fix may be setting you running straight but toe missaligned.

    Hope you follow.

    New helmet for 2024

    Hi Alan

    Having sold a few helmets in the early days of 7 Tips Racing including the budget brands. Once I finally got to try one on myself I decided I didn't want to sell them any longer.

    I completely understand we all have different budgets and my first kid was an OMP. It was great.

    You are probably closest of all of us to one of the best places to go and try some different brands out.  
     

    Merlin Motorsport at Castle Combe always keep a good range. Go and try some.

     

    Prescott?

    Has anyone else had issues signing on?

    I have both email confirmations of entry but when I visit the website and go to sign on it has nothing available.

    Will call them in the morning.

    Give me a call next week and I will explain everything. 
     

    last year we purchased a very expensive hydraulic spring testing dyno that has been enlightening.

    all I would say is you may get close with some ready reckoning math - I used to try - but you would be very surprised at the variance between springs even when new. Then you have age related sag to contend with also.

    I can happily recommend appropriate springs rates and or manufacturer.

    there is to my knowledge only one manufacturer who provides a lifetime warranty against any fail or sag and their springs can live and not be over stressed even when set coil bound.  They have won every Indy500 for the past 57 years!

    Hyperco.  It's the reason I use them.

    Any way call us and I will help out in any way I can.  All advice is FOC. No sale pitch.

    Just talking aloud here but it may be an interesting task to test as many springs as possible FOC as a way of demonstrating the variability.  Perhaps that's a winter project.

    Make sure you check the block height compared to the stroke required from the different manufacturers of the springs.  There is a significant difference and you certainly do not want to go coil bound.

    For example on our Autograss customer cars we can run a 12" spring from Hyperco with lots to spare compared to another budget spring @ 16" open.

    it's just worth an ask.

    CSR owners check your rear suspension mounts

    Both of these mounts were cast aluminium.

    we have since cleaned the "still intact" side up and both holes are cracked right through. interestingly it would seem that this was not down to corrosion between different metals.  Both the Stella collets were free to be phished out with fingers.
