I have a Tillett W1I-40 in my S3 and I can confirm that it is 35cm at the narrowest point. It's a really tight fit in a S3 Caterham!

There are different wing stays for different size wheels so you'll want to reference what wheels you have.

According to the Tony Weale book, they were 8" drums from a Triumph Herald. This should show details of the assy, parts #2,3,4: https://canleyclassics.com/?catalogue=triumph-herald-1200&diagram=triumph-herald-1200-brakes

I think this is the most plausible answer for the two bumps at the back of the bonnet. I would assume there are openings at the rear to let heat out and possibly defrost the windshield. I can't think of any other reason to have those two bumps.

There should be two adjuster cams accessible on the back plate at the two locations circled in yellow. If these are backed all the way off, then perhaps the two return springs have lost there tension and can no longer keep the brake shoes from dragging on the drums. Those shoes seem to have a lot of material on them, are they new?

I have no idea about the 2 domes in front of the windscreen, but I'm assuming the 2 near the carb scoop are for clearance to SU carb dashpots. Since the engine is supposedly a 1.2L it could be an BMC A-series which would typically come with 2 SU's.

I've been using Puma Speedcats for the last 5 years for trackdays in my S3 and find them very comfortable and acceptable on track. I'm sure they aren't as good as a dedicated racing shoe, but they seem to be a good compromise and should work well on the street too. Mine are a blue/grey suede version.

It should be in the casting like this.

I sold that Birkin back in 2015, but I think it would be your typical radiator cap that was used on an older Ford. Something like a Gates 31523 or equivalent ,as used on a mid-80's Mustang should work.

Looks good!

@Chris pike - I sent you a PM.

I wanted to update my previous post after a test drive with my son's SnoPro trailer. First thing I noticed is the shorter door makes it a little more difficult to load so some race ramps are definitely helpful, and would be essential for a car like the Lola. Total weight of trailer and Caterham is in the #2600 range, and adding spare wheels/tools/cooler/etc for a track day will still be comfortably under #3000. It was the first time I had towed with a covered trailer and it was a little weird not being able to see the car on the trailer. I think I would get a camera to monitor the car inside as @Vovchandr suggested in a previous post. As far as towing, it went really well. This trailer is about #550 heavier than my open Mission trailer so I did notice the weight difference but it really wasn't too bad. I didn't spend much time at highway speeds, but again it seemed to pull the trailer without issue. Braking seemed to be the same as my open trailer, I'm assuming that both axles have brakes but I didn't verify that. My Ridgeline has a #5000 towing capacity and keeping it in the #2500-3000 really makes for relatively stress-free towing. As we get more experience with this setup I'll give updates with any negatives (or positives) that we haven't experienced as of yet.

I use a Wix 51348XP on my Sigma-powered 310.

From last weekend at Club Motorsports in NH.

I just wanted to update this thread for another option that might work well for our little cars. My son recently sold his 16' box trailer and picked up a SnoPro Hybrid Lowpro snowmobile trailer. We just came back from a long weekend at Club in NH and it looks like an interesting option in the 7.5 x 16' size. It's a dual #2200 axle enclosed trailer that's lighter than their 7 x 16' single axle trailer (#3500 axle). He outfitted it with e-track, a fold-down cot, and was able to load and fit his Exocet without issue. A Seven would fit even easier and my Lola would fit as well. It does have a lower roof so you have to take that into account. He did say it was much easier to tow behind his Lexus SUV although I don't know what the MPG improvement was. He really liked the front hatch opening for utility/usability, and he had no leaks after having rain on Thursday night and during Friday's track sessions. I'm going to let him get a little more experience with his to see if there are any drawbacks that I haven't considered, but I could see myself getting one in addition to my open trailer. Here are some of the important specs of the 7.5 x 16' version: GVWR: 4400# Curb Weight: 1390# Payload: 3010# Axles: (2) - 2200# with brakes Rear Door Opening: 82" W x 62" H Rear Door Capacity: 1500# (I'm assuming this could be improved with a little bit of work) https://www.cargoprotrailers.com/snopro/enclosed-hybrid-lowpro-snow-trailers

A yoga mat is a lot thinner than a wrestling mat but could be similar material. It's been over 50 years since I've been on one, but IIRC a wrestling mat was over an inch thick where most yoga mats seem to be around 5mm thick.

I don't want to make a big deal about this, but at the tracks I frequent in the Northeast there are curbs you can use to be quicker and curbs that you should avoid. I've brushed up against this curb many times, but Monday was the first time I went up on top of the curb. The vibration was very surprising and was enough to trip my inertia switch, as well as send my LF cycle wing into the woods! At the 14:45 mark of this video they explain the curb I ran over and what can happen if you're not careful.

I did get a point-by on the downhill so I was off my preferred line. That's my story and I'm sticking to it! Thanks, you too Steve!

Thanks for the replies, that gives me a couple ideas to think about.

I did a track day on Monday at LRP and had my first real issue with the Caterham. I was tracking out onto the main straight after the downhill and ran onto the curbing/rumble strips on the left side, when my LF cycle wing decided to take flight and the car lost power. I'm sure I was confused with both issues happening at the same time, but it didn't occur to me that it could be the inertia switch until I was towed back into the pits. To be fair I stayed on the curbing longer than necessary, but I was surprised that it tripped the inertia switch. A couple questions. 1: Has anybody else had an issue with the inertia switch being tripped when on track? 2: Has anybody moved the inertia switch to the inside of the firewall where it could be reset from the driver's seat?
