Vovchandr Posted October 16, 2018 Share Posted October 16, 2018 I'd be quite open to idea of CSR's if they weren't all SV based =/ Link to comment Share on other sites More sharing options...
TurboWood Posted October 21, 2018 Share Posted October 21, 2018 I'd be quite open to idea of CSR's if they weren't all SV based =/ They really should throw the IRS into a std. chassis. The front shock arrangement is cool, but doesn't bring a lot of function. It also make shock/spring changes more difficult. Daniel Link to comment Share on other sites More sharing options...
Nick OTeen Posted October 23, 2018 Share Posted October 23, 2018 They really should throw the IRS into a std. chassis.I'd like to see the IRS thrown into a deep canyon; but I digress. The front shock arrangement is cool, but doesn't bring a lot of function.It does improve the aerodynamics to some degree by cleaning things up and reducing drag. Maybe not by a huge amount but some and, besides, inboard, rocker arm suspension is downright cool. Daniel Nick Link to comment Share on other sites More sharing options...

Nick Out of curiosity, is this because you are a traditionalist or based on the time you have spent driving CSRs? Link to comment Share on other sites More sharing options...
Nick OTeen Posted October 23, 2018 Share Posted October 23, 2018 Neither. I was speaking about a different IRS. Link to comment Share on other sites More sharing options...

Or so a suspension engineer has told me, anyway. Link to comment Share on other sites More sharing options...
coffee break Posted October 25, 2018 Share Posted October 25, 2018 My guess is the SV was used for these modifications has something to do with its' width. More room to hide the bits inside the bodywork. Link to comment Share on other sites More sharing options...
Croc Posted October 25, 2018 Share Posted October 25, 2018 Sean - That was definitely achieved by the modification. But there were others. Below is a link to the original Multimatic project powerpoint (spelling mistakes and all!) https://www.sevener.fr/fichiers_articles/caterhamsuspension.pdf Coffee Break - you are right. There were a couple of things causing the decision to fall that way 1) It was easier to start with the SV chassis for packaging purposes while testing - the rear end takes up a lot of room 2) There was discussion about then engineering it for the regular chassis but it was cost prohibitive - it is quite an expensive chassis to build relative to the regular S3/SV since it still has to come from Arch and 3) I have heard it said that the original marketing plan for the CSR was to be a grand tourer and a range leading model that attracted a new segment of customers to Caterham looking for a more refined product - something that was partially achieved. There were at least 2 IRS cars built on the S3 chassis. I think one of those may have been a Caterham technician building his own personal car in his own time. They have come up for sale in the UK from time to time. Link to comment Share on other sites More sharing options...

Croc Posted October 27, 2018 Share Posted October 27, 2018 John - I found it when noodling for a new kit in 2009. It is hosted by a keen Caterham owner in France. Not sure where he found it from? The other information came from one of my discussions with Caterham senior management over the years. Link to comment Share on other sites More sharing options...
