@tvacc messaged you about the roll bar that you may or may not still have for sale.

It all comes down to profit. They likely saw enough demand for both models to justify carrying more SKUs, manufacturing processes/setups, etc. For a company whose mantra centers on simplification, this does feel like a step in the opposite direction, at least from a manufacturing standpoint. I would be curious to see the sales figures comparing the SV and the S3.

Nice finish on carbon layup! I'm never done this before, so don't take me too seriously. Instead of a load cell, maybe you can use an inexpensive stick-on strain gauge. You'd probably want it on the bracket under the wing, or the base of the swan neck, closer to the roll bar attachment. You're going to have a lot of different forces in multiple directions (drag, lateral, downforce). The gauge will pick up the total of all of these, but as long as you align it vertically, downforce should be the predominant one. You wouldn't get precise values, but perhaps good enough to measure relative improvements as you make changes.

I can imagine a diffuser on the back as well. It looks like you can get a load cell and amplifier to work with Arduino. Integrating the load cells would be a little tricky, but it would be fun to collect some data and experiment with different attack angles.

Excellent use of the 3D printer! The ability to quickly and inexpensively iterate and try new things is so valuable.

@NSXguy Excellent! Thanks for the confirmation.

@NSXguy Did you have any rubbing issues with 195/60/14? Plenty of clearance?

FREE! - If picked up.

Looking for 5.75" OEM black headlamp housings/shells/bowls. Thanks!

Need to make some room. All offers happily considered.

@IamScotticus Anything is possible.

I have a set of clamshell wings that I am hoping to find a good home for. They came off an approximately 1989 S3 Imperial Caterham. They are in excellent condition and have spent most of their lives in storage. There are no stress cracks or damage. They are already drilled for mounting and for lights. I am located in the western Connecticut and Massachusetts area. I would prefer local pickup, although I can arrange shipping at the buyer’s expense. I am not entirely sure what a fair price is. New wings from Caterham appear to cost about $340 after conversion and duties. I am thinking $350 dollars for the pair is reasonable. If I am off, please let me know.

@MV8 I can confirm this. It looks like there was a conversion that Sevens and Elans provided during this era. Here is the document I found in the manual. @NSXguy It looks like your car had this as well.Seven_clutch_conv.pdfSeven_clutch_conv.pdf

great idea!

The tire carrier is a good point. I am glad you mentioned that. I would think a 195/60/14 would be fine. Then again, I am wondering if carrying a spare is even worthwhile for me. Thanks!

Oh man, these look good.

Great input! Thank you. How much mileage are you getting out of a set of 888Rs?

Nice Cat! That tire looks like a good option. Well rated. Unfortunately, they are not available in my area.

I need to replace the tires on my newly acquired 1988 Caterham. It has fourteen inch wheels and the current tires are 185/60/14. What would be the optimal setup for both tire selection and size? I have been considering the Toyo R888 in the same size, but I am not sure if I would regret that choice for street driving. I do not plan to drive in the rain, although some moisture on the roads in the Northeast is unavoidable. Any advice would be appreciated.

I know I might get roasted for this, but I’m thinking about having a local shop go through the car if I can find someone I trust. I just don’t have as much time as I used to. Does anyone know a trustworthy shop in the CT, MA, or NY area? It looks like this shop has seen some Cats. Has anyone had experience with them? https://www.automotiverestorations.com/

@NSXguy That's it! I like what you did with the support/mount. I can see a lot of slop which your setup would eliminate.

I am quite fond of the wheels. I'll sell you the tires though. They are only 35 years old.

@NSXguy This is really helpful. Thank you for taking the time to put this together. Everything makes a lot of sense. It has a Dedion rear end, which should make things a little easier. What is your UK source for coolant lines? These seem to be a little difficult to track down. PS: I am in CT as well. Just north of Hartford.

I thought something looked out of place with that slave cylinder. This makes sense, now. I appreciate the help!

It's only an hour to get the car home, but I'd like to take advantage of the heated shop and lift to get things done. Great suggestions! Thank you! Good catch on the fan. The previous owner wired the fan to a switch on the dashboard to control it manually. I assume because it ran on the cooler side, but I am not sure. Any idea how I could ID the slave cylinder and find a rebuilt kit?
