AlanO Posted February 4, 2021 Share Posted February 4, 2021 So, my first post! I'm looking for some help and advice please. I've decided a Caterham is No 1 priority on my bucket list, although as to yet I haven't sat in one, let alone turned a wheel. I know I need/want an SV (girth rather than height, 14st/5f 6in) and am tempted by a new 270 or 310. But the wait will be agonising (Sept 2021 and that's if I order now, 'blind' without a try, which I wouldn't do). So, I've seen a 2014/15 SuperSeven Supersport for sale, good nick and apparent low mileage etc.My question is about the reliability of the LSD and 'sprint' gearbox, and any drawbacks with the sprint gearbox (ratios etc) given I'll use it almost exclusively for road use. Any advice greatly appreciated. Many thanks. Link to comment Share on other sites More sharing options...

Wrightpayne Posted February 4, 2021 Share Posted February 4, 2021 Welcome,Re LSD - depends on what type fitted. There has been a recent lengthy discussion about the (un) reliability of Titan differentials and some owners needing them rebuilt in 2 to 4 years (depending on usage). Having an alternative fitted can be £800-1200 depending on type. A quaife ATB is not a true LSD but is suited to road driving and occasional track days. Sprinting or hard core track driving then owners recommend the tracsport LSD.Re gearbox - could be either a ford sierra or mazda MX5 gearbox - both are designed for much heavier cars and are usually fine. The normal first ratio in the ford box isnt ideal and can be changed. Not sure about the mazda box ratios. Also could be Caterhams own 6 speed which again is good and shares some parts of the ford box.RegardsIan Link to comment Share on other sites More sharing options...
Tazio Posted February 4, 2021 Share Posted February 4, 2021 Alan,I not sure why you think you need an SV, I'm a similar height and weight and fit snugly in my Tillet seat, so with ordinary seats, I'd be rolling around !.Not sure what you mean by Sprint gearbox, but both the 5 speed and 6 speed boxes have a good reliability record, I've never had any problems with any of the 5 speeds in the 7s I've had. LSDs, there's much been said on these pages regrading carbon plates in the later BMW diffs, but this was I believe caused by a change in materials BMW implemented, and subsequently changed again. The Titan lsd has come in for some stick recently, mine lasted 17 years before it was rebuilt, it's like most things, people will always talk about problems, but the silent majority rarely talk about their boring experience. Go to a local club meet and kick tyres , go and sit in a few,and have a few rides, you don't need to spend loads on a new car, all Caterhams put a smile on your face.

John Vine Posted February 4, 2021 Share Posted February 4, 2021 Welcome, Alan.SV vs S3: Well, I'm 14st too, but taller @ 5' 10", and I find the S3 is a very snug and comfy fit with the standard leather seats. I think it will depend on just how broad in the beam you are, and whether you plan to carry a passenger regularly. I very rarely carry a passenger (Mrs V claims the car is too noisy, but I can't see the problem), so touring luggage space is not at a premium.Do you have more details of the Supersport -- trade/private? -- a link to an ad, perhaps? If so, we could check over the spec for you. Whereabouts are you? I'm sure there'll be members near you, or even a local Club meet (post pandemic).JV Link to comment Share on other sites More sharing options...
AlanO Posted February 4, 2021 Author Share Posted February 4, 2021 Hi JVHere's the ad. https://www.carandclassic.co.uk/car/C1265591 Yes any comments would help please. I'm inclined to give them a call but appreciate lockdown will be restrictive. I'm in Hertfordshire.I've veered towards SV mainly cos I'm likely to carry a passenger who would appreciate a little extra space, plus the drivers footwell space (although only size 9 shoes). I appreciate that once we sit in a car many of my questions and apprehensions will fade. Cheers Link to comment Share on other sites More sharing options...
Leadership Team Toughie Posted February 4, 2021 Leadership Team Share Posted February 4, 2021 Welcome, Alan.I wish I'd had the sense to do what you have done, and joined the club to help me hone my choice, before I'd bought my first 7.Had we not been in lockdown, I'm sure a few of the local owners would have been happy to take you for a trial flight, where ever you are.But as Tazio says, they're all great cars.

coffeekid Posted February 4, 2021 Share Posted February 4, 2021 I would try sitting in an S3, I think you could be surprised. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted February 4, 2021 Share Posted February 4, 2021 Welcome,An S3 should be fine, if you need a tad more hip width the leathr seats afford this as the Tillets have sides on themIf your buying new it will be a 5 speed Mazda box, ratios are better though not perfect, go for the open diff and have a Tracsport LSD fitted - a proper piece of kit, the Titan has design flaws and the Quaife ATB offers little performance over an open diff.Where are you in the country..?If your looking for used cars well worth calling Jon Vickers @ Millwood Motors in Dursley.

ScottR400D Posted February 4, 2021 Share Posted February 4, 2021 Again, not sure what is meant by ‘sprint’ gearbox. Presumably the 6 speed which would have been available as well as the Mazda in 2015. If it is the six, it’s only weakness is high revs on long cruises. As far as the LSD is concerned, it will be the suspect carbon plated era.IME and the experience of several friends and club members, if you have a 270, or equivalent, it’ll probably be fine. So that car shouldn’t be bad. If you have a 310 it may well be fine. If you have over 200bhp it may well not work for that long. If you have over 210bhp it most likely won’t last too long.Just my experience and opinion. Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted February 4, 2021 Area Representative Share Posted February 4, 2021 Welcome Alan.I can't answer your specific questions but, if you can afford to purchase straight away, I would do it. As well as Caterham Cars themsevles, there are several well established dealers, well known within the Club and long term advertisers (i.e. supporters): Jon Vicker at Millwood, UK Sportscars, GP Sevens & Sevens & Classics.They will all have established ways for you to view and assess cars remotely over the past year.

AlanO Posted February 4, 2021 Author Share Posted February 4, 2021 Thanks Stephen (and others who have commented)This is one in particular I'm looking at relatively seriously.

Wrightpayne Posted February 4, 2021 Share Posted February 4, 2021 My only observations on the car is to a) check the age of the tyres - there will be a year / week number embossed into the sidewall. Usual recommendation is to change at 5 years old. Those tyres haven't been available for a while and I expect were supplied with the kit noting the mileage! And b) the roll over bar isn't approved for club trackdays (no diagonal brace). May or may not be an issue for you.I would check what gearbox (ford / mazda / caterham) / diff (ford / BMW) it has in relation to previously mentioned Titan LSD issues.I'm not sure what to make of the Q plate reference - to me it feels the seller doesn't understand the meaning of Qs?? A Q plate (in the case of Caterhams) was assigned when there was more than one component that was second hand eg the gearbox and differential were reconditioned components. If it was one part then it could have an age related plate IIRC. The car you are looking at would have been a kit of all new parts so would always have an age related plate.IanPS - I'm 6'1", 15s and a bit and size 11 shoes and fit in an S3 Link to comment Share on other sites More sharing options...
Ballast-ic Posted February 4, 2021 Share Posted February 4, 2021 That particular car has been on the market for a very long time, which would raise my suspicions. I recall a previous post enquiring about it and the more experienced members casting aspersions about it (post may have been on another forum I can't recall). As previously mentioned, check out the established Caterham dealers as for that budget you should have no problem finding something. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted February 4, 2021 Share Posted February 4, 2021 Interesting point re Q plates.....Technically a lot of Caterhams should have been Q then as the 5 speed gearbox (Type 9) and final drive (Sierra) were both reconditioned items... however when they were supplied by CC they were classed as new.... Unless there was a loop hole which permitted them to class both gearbox and final drive under the transmission heading..? Link to comment Share on other sites More sharing options...
StevehS3 Posted February 4, 2021 Share Posted February 4, 2021 Are the brake calipers reconditioned too? Surely they don't still make them Link to comment Share on other sites More sharing options...

Area Representative Golf Juliet Tango Posted February 4, 2021 Area Representative Share Posted February 4, 2021 Alan, I am also nearby, in Berko but mine is an S3 not SV. The problem you may find is that an SV is not just broader but longer in the cockpit. Link to comment Share on other sites More sharing options...
