It’s 100degF and the car has run hard all morning using up two full tanks of fuel. Now cooling in the shade at lunch.

yes front rear

They will not be available as road tires but may come in as track tires - to be determined. I imagine you could import yourself? They are the standard tire for Caterham race series replacing the Toyos. Very good tire. Takes a relatively long time to scrub in - 15 mins of track time. Quite slippy until scrubbed in. I had no problems getting them up to temp as its warm here but, according to the other race guys here, in February in winter on a cold track, they will never come up to their optimum 26psi hot no matter what you do. I was releasing tire pressures after each session to keep at 26psi hot. Not quite as good as the former Avon ZZR - fraction less grippy - but still a superb tire to track a Caterham on. Releases very gradually so you get lovely drift rotations under throttle in corners. Really flatters as a driver. Very communicative about losing grip so very easy to catch - somewhat like a bias ply tire in that respect. It turned out a hot day but the MRF tires were consistent all day. Wearing quite well. So much nicer than the Toyo R888s I was using at Le Mans the previous day. I will use these from now on until the Novas come on line. I have an order placed for a set of Novas which may be available for my Zandvoort trip in September or Spa in October.

Yes your memory is matching mine - it was advertised on Hemmings for a while. No ad live there now. Cannot recall what price he was asking.

MRF tires being tested today. Someone here has a set of Nova slicks to try out today.

Apologies - it was @theDreamer who posted it there. Forgive me for confusing two equally handsome gentlemen - I cannot tell you apart. Either way - it was posted in the thread I referred to.

I did draft one but then some person here stated he thought it was a great idea as he could then sue the club if he messed it up on track and that would pay for his repairs. Just confirms why we can no longer have nice things. You can google and find the C&L7C version which by virtue of being located in the UK, can post such things publicly without fear of lawsuit. One day I will do this - probably have to wait until I retire sadly. I agree with Carl's observations - these cars are good out of the box from the factory following the standard specs. There is a lot you can customize but you have to know where you are as a starting point. It may be perfect just as it is. A note of caution - this thread will produce multiple differing recommendations that likely conflict with each other. All reflect each person's own experience based on their context. You should consider everything and make your own decision based on your own circumstances, environment, track condition, your own driver skill/comfort level and car condition on the day. We will not be there to make the decision for you. I don't get this. I never seem to have a brake problem and everyone else moans. I suspect the answer is that I am dialed into the brakes on a Caterham. I think the problem is that most people are all dialed into power brakes and have never used manual braking systems before (or its been a long time since you last did). Yes you will need a hefty foot press of the pedal to get bite but you will also need to have the foot/sensitivity to modulate the pedal pressure for things like heel/toe and trail braking application. To avoid heating brakes up you need short sharp braking applications and not long applications at only say 80% of pressure. Make sure your brake fluid is fresh and have driven on this to ensure correct operation before going to the track. Check your fluid spec is rated for track usage. Be sensitive to pedal growing softer on track as things heat up. Refer here for my starting point for my UK 420R - I have tweaked beyond this for my personal preferences. Its close to what Carl is suggesting above but he is also reflecting his personal preferences as a driver. Each driver has an individual style - these cars are so customizable for individuals but you have to start somewhere first. Ignore anti-roll bars for now. Drive as is and decide if it works. Caterham do a good out of the box set up based on their standard options. You want a very good baseline of how the car handles before you get sophisticated and change a lot of stuff. I suspect most people cannot tell the difference on track between setting changes - it takes me laps of repeating corners to discern a measurable difference from a degree of change in caster or camber. Second point against anti-roll bar changes now - you are proposing to stiffen the car's suspension. What if it rains? You want the set up softer for now. Softer set up helps the weight transfer around the 4 wheels - easier for you to feel what the baseline set up is doing. Remember your intended usage for your Caterham. You want to use it on road and track. So it needs to keep a hybrid set up suitable for both. There are no trophies on a track day. The Ferrari F1 Team Principal will NOT be on the pit wall measuring your performance by checking your lap times. There is no lap timing. Relax a little. Learn the car as is. This is personal preference but you are aiming for an optimum HOT tire temp of around 25degC (someone convert me to F please). So the starting cold tire temp needs to adjust depending on the ambient temps of the day. Its summer in CA. Reasonably warm and pleasant. Follow Carl's recommendation and test after one session. Don't get too hung up on precise temps as this is a track day, no trophies, etc.... Keep in mind these are 888Rs. You have 1-1.5 hours from new when they are good. They will go off by the end of the day. You will know this as there is a point when they start to understeer like pigs on track once hot. Its not you - its a characteristic of the tire that the UK racers (and hackers like myself) have found over time. The UK race guys use these tires for just one or two sessions and then discard as they are done for grip. Don't go too low - anything below 17psi runs the risk of ripping the tire bead off on hard cornering. When you get out on track, take it easy the first 2-3 laps and let your tires come up to temp so you have some grip. Cold tires have little grip. If it is running the standard thermostat provided by Caterham then it is going to run at thermostat temp that they decided the engine is optimal at. Its also summer in CA - so I don't know why it would run too cool unlike a winter in upstate NY when the car would genuinely struggle to ever reach optimum operating temps? I have never blanked off a Caterham grille except for one day at Spa-Francorchamps in snow and ice conditions. Anyway, engine temps were never my concern that day, it was the condition of my underwear from driving on ice/snow! Try it out - monitor the oil and water temps and see what it runs at. Water temp should peg at the thermostat spec. I am a firm believer in letting the oil temps warm up to operating range before heading out on track. Start the car 5-10mins early and idle it to let everything just warm up naturally. Always spanner check before you get to the track. The day of the track day I always do an oil level check and visual once over at the beginning of the day and before each session for obvious problems. Ask @S1Steve about dragging exhausts on track days! (Sorry Steve!). One last note - this is a track day. Your standard car insurance will likely not cover you. Keep it simple as you learn the car's behaviors. Don't go like a bat out of hell out of the box. Take it easy and work your way into things. The easier you take it initially will allow you to sense a problem early and stay safe while you get back to the pits to diagnose. You want to drive your car home at the end of the day.

@IamScotticus Is this your car for sale? If not then I will remove this thread. Sellers can make ads for sale. No third party friend of friend stuff. Buyers need to know wwith certainty who they are dealing with on expensive purchases. You have the long running thread of car ads found to put things like this - but @wdb already has posted this.

Its called an A Frame. Its part of the rear suspension for a Caterham. It may be straight but does it have any dings or divots in the powder coat that would be a harbinger of possible damage? Then to ask the second obvious question - which model Caterham is it for? An S3 or an SV? Then which S3 chassis - imperial or metric? From the design at the top of the A, I suspect it is an S3 imperial but a prospective purchaser will need to validate that with you.

That is a BMC A series engine number format. I once owned (a very long time ago) a Lotus 7 S2 with an A series engine - it was my first seven. Great little engine.
