  1. I fronted up to Zandvoort in The Netherlands to do a track day with RMA, a UK outfit with a good reputation. For some reason I ended up being the only TFL Racing supported car at this event. My car arrived in a small trailer towed by a trusty pick up driven by Dickon who was my support crew for the two days. Given what later emerged with the weather I think the others were more sensible in staying away. I was also joined by a family member. The Zandvoort Circuit has a long history back to the 1930s, carved into the dunes behind the beaches facing the North Sea. Its not Florida but to Europeans, it is an exclusive seaside resort. It is the home of the Dutch Formula 1 Grand Prix although for how long is a major question. The track of today was heavily modified 5 years ago to make it more suitable for Formula 1 safety needs. Despite this, the old character still shines through. This section below is still readily familiar when you drive it today. The track is well suited for spectators with lots of dunes and mounds of sand to get great views of the cars on track as they weave and undulate through the sand dunes. The week before I turned up I had to scramble for a garage as it had been forgotten originally booked plus the weather forecast was not looking great. Fortunately I secured one, right next to Mickey's Bar at the end of the pit complex. Keen eyed observers will notice the yellow vinyl sticker with a black cross through it on the back of the car. This was the rookie sticker to alert cars coming up from behind that a newbie to the circuit was ahead. While I had been to Zandvoort before, I also had a family member with me driving my car who had not. I stayed in central Amsterdam as the accommodation options were more plentiful plus many dining options for the evening - its only a 40 min car ride to the circuit. Zandvoort at this time of year is a ghost town and not a fun place to stay in off season. The weather forecast was grim. Day 1 - intermittent showers with strong winds. Strong winds ended up being 45mph with with gusts up to 65mph - those gusts are technically hurricane strength. I was hoping that the dunes around the circuit would protect me. A fair amount of standing water around the track was going to require some delicate driving given the conditions were marginal for the Toyo R888R tires - my wet intermediate choice. I do not have full race wets. The dry slick tires stayed in the trailer. The cars at an RMA event are high end. A lot of Porsches. A good scattering of BMW M cars. There were a few of those space frame Beetle looking Fun Cup things. There were two other Caterhams - a 620R and a 420 race car. The 620R was only out there on day 1 as he only had Avon ZZR tires and given the condition sensibly stayed under cover on day 2. The 420 race car was running full race wets and so was making me insanely jealous by showing off how much grip he had all over the circuit. On day 1 the track did dry out mostly. Turn 1 was marginal all day - I could not get the car to stop and used the run off at the end of the straight quite a few times to save myself. A combination of damp/wet track, cold temps, the light weight of a Caterham, just could not get the tread on a R888 to grip. You can really see the sand dunes in the background looking towards the North Sea. Turn 3 is a fascinating corner. A deep bowl, it has lots of G forces as you hammer through. You could dive deep down to the inner kerb but the faster line was to stay high and hold more momentum through the corner. The old character still shines through. Look at the sequence of the next two photos - first from the 1950s and the next from this year. This was my favorite part of the circuit as you swoop through the undulations at high speed. However, it was a bit tricky for me. One time I was caught by a wind gust and found myself with opposite lock to stay on track. Apologies for the sound but this short video below shows the sequence through turns 2 and 3 with turn 3 being the dished banked corner. Video Sep 15 2025, 5 04 16 AM.mov Naturally the way to recover after a track day is with some hydration to warm back up. Day 2 was not good. Lots of rain - mostly torrential. Video Sep 15 2025, 9 20 56 AM.mov My approach was to use the dry window at the bbeginning of the day to get as much time in as I could. So I went out for an endurance stint as soon as the lights went green. Two hours later I came back in with the fuel tank on red. I always liked endurance racing when you just get into a mental zone of being super consistent and smooth on the car. Below shows the car coming through the final banked corner onto main/pit straight. The rooster tails of water show the level of standing water on track. It was a struggle to get the car to stop let alone grip in a corner or apply power without getting snap oversteer. Headlights needed to be on. You really could not see cars coming up behind you in the spray unless their headlights were on. This section of track saw me managed to do a 360 degree loop when I messed up a heel and toe downshift, but I still managed to keep momentum and drive off in second gear. The track photographer was right there but he said to me later he was so surprised he forgot to take any photos of my looping. Lots of race cars were present using the days as testing for future race events. Being race cars they had full wets so were far more capable in the conditions than what I was able to achieve. Its still fine to drive but you have to adjust for the conditions. So I was a lot slower. My accompanying family member only went out once on day 2. He said he preferred his track days like his martinis - dry. He was mostly found keeping warm in Mickey's Bar! Despite the weather, I have booked again for September 2026. This time I have booked a garage and will seriously consider better wet tires - likely a full race wets although maybe the neww Nova ZZS will be available by then.

  2. Quite a few states have this requirement. I think I used a steering wheel cover once to grow an inch in diameter.
  3. Caterham on Bringatrailer https://bringatrailer.com/listing/2024-caterham-seven/
  4. Trying to source parts in a tariff world is not cheap. Then at the end of it all it is still a salvage title so compromised end-value. At a couple of thousand you could part it out to make money.
  5. You have not got much choice but the R888s right now. They are fine for road. Ok on dry track putting aside they “go off” after about 45-60 mins from brand new. Ok as a wet intermediate tire for road and track. Watch them on really wet conditions as they are tricky to gauge grip. Lethal on standing water.

  7. What about adding a set of these to your newly installed brake lights?
  8. I would monitor that gap on days when you are not driving to church. Given you will be running these at low pressures there will be a fair load of tire rubber deformation in corners. The clue that you have a problem is when you start to see missing paint...
  9. Which wing stays did you order for your car? The 13 inch wheel ones or the 15 inch wheel ones? There is something like an extra inch in the 15 inch wheel ones.
  10. Yes but why were you using them halfway down the main straight?
  11. Is that before or after tire deformation in a corner?
  12. I think that works well for a version 1 edition. I suspect it will give a better cold air seal too. Probably no extra hp though!
  13. Only thing that concerns me is the front stays once tires are on - it will be close I think. Who are MCS?
  14. Thats the type of comprehensive thinking to develop a well-thought out work plan that some many on here could readily learn from - nicely done!
  15. What is your short list of products for this? Any target goal for incremental hp?

  17. Yes there is some truth to that. Requires more of a ‘V’ shape cornering shape than the usual arc. The other trick was to use a spool diff and make the front soft and rear stiff so that the inside rear would lift up on hard cornering allowing the car to rotate quicker as you only had one wheel touching track surface. The spool would then help traction out of the corner once both wheels were back on tarmac. Again a V shape cornering shape works best. Spools are normally found on a drag strip.
  18. A 3.6 will lower revs. If it were me I would drop from 3.9 but check road speeds via a gear calc spreadsheet. I can attach one here if you need. I’m not surprised it failed. 10-12K is all you can expect from the Titan internals on average. They are poor quality. I have a BMW/Titan diff on the workbench that failed at 4400 miles. Explore the warranty with Greg but your mileage probably eliminates that option. Look to buy a whole new unit and then replace your existing. You can then rebuild what you have and sell to offset cost.
  19. @CBuffWhich diff do you have? Sierra Ford 7 inch or 2010 BMW 1 Series with Titan internals? Your car’s age plus the fact the LSD failed so early leads me to think you have a BMW diff, which is different to Blake. You may have a warranty claim too - the Titan internals have been well known for failing early. Different diffs mean different driveshafts. Have not heard of a Tracsport diff going into a BMW housing but I’m sure it’s possible. Also you would want to check what final drive you want as this is a good opportunity to make a change. It is possible to do Wrexler and Wavetrac internals into the Caterham BMW diff plus take the final drive ratio from 3.9 to 3.6.
  20. And this is why I decided many years ago to never use UPS again.
  21. Its that time of year when you think about stuffing - in this case a Christmas stocking of gifts to ourselves that we want to generously add to our cars. In that mindset, I came across the following website site, which had many little Christmas gift ideas that will fit in a stocking, on a se7en... https://uberniche.co.uk/ With this in mind, what "presents" or upgrades are you getting for your car(s) this Christmas? @JohnCh Why haven't you done these on your sexy new 3D printer?
  22. This subject has not been addressed and is remarkably common although most owners ignore it. So your somewhat stock 620 under bonnet configuration will look like this: The cold air intake is the silver looking pipe that heads down and curves to the left to a black box then the rubber grommet that sits between the intake and the inside of the bonnet. To rule out the bleeding obvious by those unfamiliar with the 620 engine - it has a supercharger. The traditional upgrade path for regular Caterham Duratec engine owners of Caterham roller barrel throttle bodies is not a viable option. Not a lot of room to work with either - and the photo is an SV. Knowing that, lets see what you can suggest for Pickles.
  23. Nova tires now exist. I had a photo shared with me at a UK track yesterday where Nova were doing the first UK test of the new 13 inch ZZS and 13 inch ZZR Extreme. Tread pattern identical. Not sure I can share photo without someone getting into trouble. Nova is branded where Avon once was. The ZZR was a 185/55 sizing. Could not see the ZZS sizing from photos. The Caterham looked to be running a square set up with that size all round - makes sense as it was a 310 spec. Obviously no results of testing are available - it will be a corporate effort to see what the newly produced tires do in the real world. Track day or motorsport only - will not be road legal unless you ignore such niceties. But at least Nova tires exist and have been seen in the wild.
  24. This is a 2026 event. I don’t have dates for 2028 yet.
  25. Not sure on the name, but those thinner wink mirrors for sevens were produced by a USA7s member, Bob Simons. Sadly he passed away earlier this year. You could try searching for golf cart mirrors - they were using a narrow version of the wink mirror at some point.
