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?
