Good morning, I'll take this if it's still available please. Regards, Adam

Good morning, Is this still available or has it gone? Regards, Adam

TWOTW is correct - it is indeed the whole assembly - case, internals the lot. The diff is now sold. Thank you all for your interest and assistance. Adam

For sale on behalf of a friend, a brand new Raceline Duratec oil filter housing. Details here This is the M12 × 1.5 variant and comes complete with bolts and gasket. £60 plus p&p (£95 + VAT from Raceline) or collection from Horsham or Sevenoaks. Any questions please ask. Many thanks, Adam

Thanks Olly - original post edited to provide a bit more information (and spelling of Olly changed to your version!) ...!

For sale Titan Sierra 3.92 limited slip differential with ‘Sintrak’ friction plates. Built by Road and Race Transmissions fewer than 1300 road miles ago. Full information here. The pre-load has been checked by Olly at R&R since removal and found to be correct. £750 ono I'd prefer collection from Sevenoaks, Kent, but will post at cost if necessary. I can also move it to the Horsham area fairly easily if that helps. I you have any questions, please don't hesitate to ask them. Many thanks, Adam

Hi Ed, Apologies for the delayed response. I've sent you a PM. Adam

Apologies - should have said - Ital ...

On behalf of a friend. One live axle half-shaft. Free. Collection only from either Horsham or Sevenoaks. Adam

I'd use cap-head bolts for the seatbelt/harness mounting bolts and Araldite some popper bases into the tops of those and use those to secure the boot cover at the front. Or you could just drill into the standard normal harness bolts and rivet a popper onto the top of those. Or just Araldite without drilling if you have concerns about potentially weakening the harness bolts. FWIW ... Adam

I'll jump in on the proviso that it's understood that I'm mildly experienced but no expert in any way, shape or form ... Regarding the air intake, I have Jenvey TBs getting their air through an in-line K&N from under the radiator - no bonnet cut-out (and it's an Imperial S3). I believe Jenveys are about half the cost of the full RBTBs. I'm not sure they influence power greatly, but I think the throttle response is supposedly somewhat sharper. I can't see why you'd need a rolling road session or a new ECU with this change, but it might be that you would and there would probably be benefits, minor or medium. As for exhausts, Powerspeed are always well spoken of - I have a 4-2-1 from them - I think the 4-2-1 is supposed to give better torque than a 4-1 but I also seem to remember Chris at Raceline telling me a while ago that the gains were marginal, bordering on negligible. I've had two Duratec-engined Sevens. The engines were identical except that one had a mildly ported head. BHP figures were the same, but the torque for the engine with the modified head was significantly higher, so maybe that would be an idea. My understanding is that the Duratec flows very well even in standard form, but there appear to be improvements to be had - though I'm not going to suggest any certainty on the basis of a single data point. I guess a 2017 car has the Mazda gearbox? I don't know what the ratios in that are, but if they're not similar to the ratios available from Tracsport for the Type 9, I'd be very tempted to be looking in that direction for an improved 'driving experience'. Those are my thoughts, for what they are worth ... Adam

This is a truly great club with truly great people - it has been for ages. Over the years there have been some exceptionally knowledgeable people on here - and there still are (I'd love to include myself, but I most certainly do not). What irks me the most is that that knowledge has become frequently inaccessible because links prior to whenever are now redundant (and I acknowledge that in some/many cases those links would lead to a 404 Page not found error, but there's still wheat amongst the chaff ...). When one finds oneself hunting out archived copies of the site to retrieve information that one knows was once readily available there's something wrong. I repeat: great club, great people (and fantastic cars). Adam

Here, here - split wanted and for sale, sort out a decent search facility and please, please, please restore all the broken links.

David, I don't think there are any disadvantages whatsoever - I think it's an eminently sensible route. The only possible drawback is the factor that the car becomes non-Caterham spec which could be perceived as a drawback if you ever come to sell it. Personally, my feeling is that not being tied to Caterham and their rather petty attitude about locking ECUs and what have you is a plus point and commands a resell bonus rather than a discount. You mention that the SBD option is a similar cost - I'm slightly surprised by that - from Raceline (whom I'd recommend highly) cams, verniers and ECU would be about £1100 I think (probably plus VAT I suppose). In short, I'd have no hesitation in following the SBD or other (non-Caterham) route ... FWIW, Adam

They look most impressive - very smart and professional indeed. I'd be very interested in some more details of how you made the support structure.
