Hi all I joined the club recently and have been ploughing through the extensive back catalogue of guides, technical briefs and posts, but a combination of my lack of searching and winnowing skills, and there being quite a few different engine and car types have left me with a couple of simple questions still to be answered. The car is a 2016 Roadsport R with a 125hp 1.6 Sigma engine. Its road legal, with my guess being that its life will be half spent on country lanes and half going around a track. I'm only very vaguely competent with a spanner - I owned a Subaru Impreza previously that I'd fettled with myself to make it better for the track (upgraded brakes, changed the intercooler, installed oil and boost guages etc) but that was a while ago so be gentle! Oil - I'd used Silkolene with my Scooby when tracking it, bought from Opie Oils. Assume Fuchs Titan Race Pro 5W 40 (the new name for Silkolene it seems) would be a good choice with significant time spent on the track? Tyre pressures on the track and road- I've currently got Avon ZZS (185/55/R13). My plan is to get an additional set of wheels and put tyres that work better in the cold and wet on them, but for now what would be a good set of pressures to try for the road and then also for the track in colder weather? Torque for wheel nuts - couldn't see in the Ikea style build manual I downloaded? Battery cut off - Is it enough to flick the battery cut off switch when leaving the car in the garage for a couple of weeks, or will I still need to get a battery conditioner? On the Scooby I had a detachable connector so when I knew I wasn't going to use it for a few weeks I would quickly disconnect the battery which would save it from draining too much. Obviously long periods of storage would need a conditioner anway, but hopefully it'll only be 2 or 3 weeks between runs out on the road or track. Size of hex key for radius arm bolt behind the seat. The guy at the dealership mentioned that one of the things to check is whether the rear radius arms are loose after significant track running (he races a roadsport and finds he needs to tighten his from time to time). One side of this is in the wheelarch, but the other is down the side of the seat and looks like it needs a long stubby hex key to get to it without taking the seat out. Anyone know one that would fit (not just size of bolt, but slip down behind the seat into it)? Specific Caterham-y things to check when tracking it. As with the Scooby I'll need to check things like fluids, wheel nuts and tyres when preparing for a track day, but like the radius arm bolt, are there any other things that are more specific to caterhams that I wouldn't think of (like ensuring the pin is out of the extinguisher in the boot) ? Thanks in advance - apologies if I've missed something obvious in the guides etc that answer some or all of my questions (don't worry about just posting a link in your reply, I'll make sure I dig through and then bookmark for next time!).
