For starters, you could respond to my message that I sent with the info on how to remove the immobilizer!

When Gary May and Len Unwin were developing their Freestyle Caterham, they were using the SV axle with the S3 body/chassis to widen the rear track. I don't have a link to the LowFlying article but I do have a hard copy of it (2/16 edition). This is a direct copy of a portion of the article discussing their result, and partially addresses your question: "Finding rear wings wide enough to bridge the gap between the S3's rear body and the extra length of the SV axle was more of a dilemma meanwhile, and Gary's first solution here was to create a mesh spacer to sit between the standard rear wing and the wheel arch. 'I liked it aerodynamically because it let the air through, but Len hated it - he said 'that's SO ugly'. So we changed it....and went instead for a new, wide wing." There were only 8 official Freestyle cars built, with number 7 residing in California when the article was written. I'm sure there were other standard Caterhams that were converted with parts supplied by Freestyle.

Ian - Looking forward to seeing pictures of your project.

I sent you a message.

Some photos from the track day. The one with the Miata was during the last session when it was raining the hardest. I was trying to keep up with my son who was driving the Miata, and getting ready to point by the WRX who was much quicker than me in the rain. My son had just put on some Continental tires (not sure of the model) that he said were great in the wet.

I don't have that setup on my Cat, but I'm sure it's welded and not removeable. Some good photos of a chassis rebuild here: http://www.mycaterham.com/203110/204107.html

Very cool story, looking forward to updates!

No carpet on the floors of my Cat. It's surprising how close to the floor the seat bottoms of the std leather seats are when installed. They drop down between the seat rails and if I hadn't wrapped them in a plastic bag they would have soaked up the water that was sloshing around.

So I thought I'd give a little update. The track day on Saturday started off pretty well with only a light mist early in the morning. I got in a couple fun sessions before it started to rain. The third session in light/med rain was one of my favorite drives in a Seven. There was enough traction to maintain some decent speed with no puddling or rivers running across the track. I was trying to be especially smooth and was finding out that even in these wet conditions breakaway in the corners was very progressive. Really had a lot of fun! The afternoon sessions were another story. The rain was really starting to come down and although visibility was decent because there weren't too many cars on track, traction was getting worse and worse. I think the only cars that were doing well were the WRX/STI's and a VW Golf. There were a couple spins and off-course excursions, thankfully not for me but there was very limited traction at this point. I made it worse by forgetting to put on my rain jacket and only had a MTB windbreaker on....I got soaked and there were some pretty good puddles in the lowered floor pans too! I wanted to do at least another session, but with the weather conditions getting worse, only one set of dry clothes that I wanted to save for the ride home, and a rollover in the advanced group, I decided to play it safe and pack up. Takeaways from my first wet track day? 1: As far as driving on track, there’s a lot of great advice from Croc’s post listed above. There’s not much I can add to that with my limited sessions in the wet but his advice certainly helped me. 2: Bring a rain jacket or a rain suit. You’re going to get wet and a wind breaker won’t help. 3: A tonneau cover over the passenger side would have helped to keep some of the water out. 4: Drain holes in the floor pans. I was surprised to see how much water was sloshing around after the afternoon run. Having the seats covered in plastic bags kept the leather and foam dry. 5: A canopy in the pits is a must. I can’t imagine how wet it would have been without one. 6: A covered trailer would be a big bonus, but I like the ease of towing with my lightweight open trailer. I put the windshield/side screens, and top back on for the drive home and the stock Caterham weather protection is not 100% effective. The inside was even wetter when I got home. 7: If the track offers garages or covered areas for rent, it would definitely be worth it. 8: Towels, lots of towels and an extra set of clothes for the drive home. 9: My biggest concern after getting home was drying everything off and making sure there was no moisture left in the chassis/body/grot traps. I drove it to get the surface rust off the brake rotors and left it sitting in the sun over the next few days when possible. My car is still immaculate (PPF on the most vulnerable areas) and I want to keep it that way. 10: At the next track day if I know there’s going to be downpours I’ll just take the Miata!

Thanks Croc, that's very helpful info! No tonneau cover yet, so I removed the passenger seat. I'm going out to cover up the drivers seat now (it's leather). I'll tape the bonnet louvers too. Thanks again, especially the reading of the track surface/driving line. Smooth and steady and hopefully it's a fun day!

Vovchandr - Thanks for your input.

After many beautiful clear days over the last week, I'm signed up for a track day at Palmer, MA tomorrow with the forecast looking pretty bleak. I'm going to make the best of it but will be using my aeroscreen because I've removed the wipers/motor/linkage and don't feel like putting all that back together. I have a canopy to park under in the pits but will be getting wet while on track. I'm looking for any tips that will help make the day successful. I'll be running the stock wheels with Avon ZV7 tires. Tire pressure? I usually run around 18psi RainX on the visor, will that help? Anything else, please let me know! Thanks

John - Your build is looking good, I really like what you did with the fuse box! One of the things that I'd like to see Caterham improve on is the wiring under the scuttle, and the hose layout and wiring in the engine compartment. Maybe the RHD versions are better but what a mess on the LHD versions. I'm hoping to retire (again!) in the next couple months and hopefully I can do some improvements on my car then.

I'm pretty sure I have a spare black connector that's not used on my car too. Can't remember what it's used for though, Duratec dry sump maybe?

Good info from Croc, and I would pursue his suggestions further. I would also check to see if you have a MAP sensor as documented in your other thread on the unused connectors. I'll add my experience with my 2019 310S. The only running issue I've had was a stalling problem when letting off the gas and coming to a stop. Once driving and accelerating there were no issues. I ended up getting the MBE cable/interface from SBD so I could monitor the ECU and adjust the TPS. Once the TPS sensor was adjusted to the proper voltage, the stalling issue has improved. I think this is the one here: https://sbdmotorsport.co.uk/product/mbe-map-kit-3-can-basic-can-mapping-kit-for-mbe-can-based-ecus/ You can also download the software for free from the same site: https://sbdmotorsport.co.uk/product/easimap-6-pc-software-easimap-6-pc-software-download-for-free/ I removed my immobilizer because I didn't need it and wanted to remove all that extra wiring and hardware. It wasn't causing any running issues on my car. If you want to remove yours, here's a thread on the removal on my car: I can send you more info on how to do it if you're interested.

I'm pretty sure that green connector goes to the MAP sensor. Just found a thread on it: Maybe this has something to do with your WOT issue?

That orange car sure looks like a modification of the stillborn Caterham Alpine coupe from a few years back.

I must be old, I remember that article very well. I might still have the copy!

I believe this is a new one on BaT: https://bringatrailer.com/listing/1990-caterham-caterham-7-csr200/

The one MV8 posted looks to be the same one on the Burton site: https://www.burtonpower.com/crank-spigot-bearing-21x15mm-fp347.html

I'm curious to know what Triumphs had inboard discs. I know the E-type did but I don't recall any Triumphs with inboard discs.

Congrats Steve, quite an accomplishment!!
