I have to imagine a wet sump 7 on non slicks would be fine, but that's based on absolutely nothing. If its in the budget, I would vote dry sump. Not only for peace of mind but it also gets your more ground clearance if that is important to you. Only when I need to check or change my oil do I wish I had a wet sump.

Thanks @CBuff. Are you in an S3 or SV? I'm obviously unsure having never done it, but it seems like the b23a with a snap in would either not fit or be very tight. You are getting at what I was hoping though. I don't need to have the same bracket as the factory harnesses, just any bracket that can accept a 7/16" mounting bolt, right? I think I could do: b24 brackets all around (1/2 inch hole) SR 65L (sleeve for b24) related washers if they don't come with the SR65Ls. I need to pull my seats again to verify, but I already have sub-strap mounts from the factory substrap I think I can reuse instead of the weld on plates, so it should all be a bolt on affair. I am going to email HMS again and see if they can course correct me here.

I am getting nowhere on dated harnesses for this silly car. I ended up returning the Flexis because I was unable to find anywhere they could sell me the proper 5/8" bolt hole brackets and my return windows was almost up. HMS was the only place to elaborate a bit on my situation. They referred to this size as "Lotus brackets" and stated that there are FIA has rules/regulations in place that prohibit the sale of these brackets and they are required to be sewn in. They offered to sew in the brackets; $7 for each bracket and $25 per lap sewing charge. It lines up with what I am seeing - no one can help me with these harnesses :(. As of right now my only options seem to be either pay HMS to make me custom sewn in harnesses (so ~$2XX extra per side) or order from Caterham and hope they have a full 6 point available and that it is actually dated (This might actually be reasonably priced, relatively speaking). Is there is a bushing/reducer solution here where maybe I can replace the giant factory one with something more standard? The bolt going into the car is a regular 7/16th bolt, but its the bushing/reducer that requires the big 5/8" hole. Could I get a 1/2" bracket, and 1/2" to 7/16th reducer, and call it a day? I assume there is a tried and true recipe for harnesses in these cars and I am just missing it. For those that have non-Caterham harnesses in their S3s with tillets, how the heck are they mounted, where did you order from, and did they come with unique mounting hardware? Are they sewn ins with an end plates that have a 5/8" bolt hole?

Thanks I have a few more emails out, including to HMS. Hopefully I can find something. I will update if I figure out what will work.

Well, I went to install my new fancy 2031 dated Scroth Flexi harnesses and discovered that I am an idiot and they make these bolt in end plates in different sizes. The ones I got are 3/8" but the factory Caterham ones are 5/8". I can't seem to find plate that have this large of a hole though. Anyone know where I can get something that would work here?

Thanks for the info - I am going to go with the Schroth Flexi harnesses and bolt in style mounts since it seems we don't need to run "special" harnesses in our cars as long as they are bolt in. The Schroth ASM FE seem nice but I am really struggling to find the sub belt anywhere in stock and I don't think id ever use whatever harness I end up with in a 4 point fashion to worry about submarining. I do like the idea of the big red easy button though. FHR wise, I think I am going to stick with my current Simpson hybrid S. I am not trying to re-invent the wheel. I did see our friends across the pond recommending the work be done at Arch to make the harnesses correct, but i have no idea what they actually do. Maybe I will reach out at some point and ask if they would be willing to share. I will report back if I can find anything out.

I am getting more into tracking my seven and I am going to start participating in time trials as well as (hopefully) attending the USA7s meet at NJMP. This means I have to get dated harnesses, arm restraints, a fire suit, and an FHR device. I actually have the bulk of that list already or on its way, but I am looking to make a few changes. Harnesses Right now I have the standard Caterham harnesses and the sub strap to make it a 5 point. These obviously are not dated so I need to replace them. Before I pull the trigger here, I see companies in the UK sell Caterham specific harnesses, including Caterham themselves. Its not clear to me if those harnesses are actually dated though. I'm not sure how some of these harnesses are "designed specifically for a Caterham" either. I'd also prefer to order something state side for numerous reasons. Can I get any old pull down 6 point harness with bolt in brackets, or will something be weird in the Caterham, like the straps are 50 feet long or something else unexpected that might cause issues? What harnesses do people run here that need FIA dated? I am looking at getting something like one of these https://www.pegasusautoracing.com/productdetails.asp?RecID=34016 https://www.pegasusautoracing.com/productselection.asp?Product=SCH-94530 Then I would also need to get the bolt in style brackets and swap over to those. I actually ordered a set that were one year old so they were 40% off, but they're sewn in brackets with the snap in style so I need to return them Arm Restraints I just ordered these and I think they actually make a lot of sense for our cars (I do enjoy having arms), but I am a little worried about point bys. I am used to giving really obvious point bys which I assume are going to be pretty difficult to do with these. I can probably t-rex a point for a drivers side pass, but not sure about a passenger side pass. A lot of the HPDE organizations I run with do not allow turn signal point bys. Also I am worried the rear wheel fenders will obstruct the view of my restrained point bys as well. Have any of you had issues there? I will know soon enough when I get them in the mail, but I am curious to hear others experiences giving and receiving point bys from a restrained seven driver. FHR Like the arm restraints, this makes sense. Running harnesses, probably a good idea to do what you can to keep your head attached to your neck. I currently have a Simpson Hybrid S from tracking a Lotus Elise with a 3 point belt. Right now, at least with the standard Caterham harnesses, clipping in the rings from the Simpson Hybrid S into the shoulder straps is a real struiggle sometimes, especially when youre running late to the grid. Also, the back of the apparatus hits the seats making it a little uncomfortable. I think I would like to switch to a standard FHR device, but the shoulder strap angle and placement is out of whack on Caterhams woith factory mount points. They supposed to be between 0 and 20 degrees below the shoulders, ideally at 10 degrees and the mounts are supposed to be much closer together. Is it even possible to correct this? What do people do here? Just run at the incorrect angle? If this is a significant hurdle, maybe sticking with the standard mount points and my hybrid S is the best option.

I also use a Motive bleeder on my 420R and my Lotus Elise many times before that. Its pretty darn easy and works great. I agree doing it wet does waste fluid, thats my only complaint.

Thats a great idea. I already want a camera setup for the back of the trailer because I cant see anything behind. People love to get really close (I can see their vehicle's shadows) for some reason. Maybe they're hyper-miling while I get 12 mpg lol. Having a camera inside the trailer would be nice too. Did you mount the monitor in your tow vehicle? Funny you say that, I am almost in the same boat, although I can juuuust squeeze in with the hitch.

I use a hybrid hans with the Caterham 5 point harnesses. I would actually like to get new harnesses eventually so I can use a normal hans for easy or use. The hybrid is a little bit of a pain to get the lower rings clipped into the shoulder harness connection points. I have not been to Summit yet but I would like get out there at least once this year. Which layout do you like most? And which organizations do you run with when you go? Dominion is a bit more a a hike for me, but I am sure I will get there eventually too.

I was very much planning on going but I am not signed up yet. I didn't realize until more recently NJMP requires dated harnesses and arm restraints. I don't have either of those so I probably wont sign up this year unless I get that stuff squared away. Yeah I noticed they do Wonderful Wednesdays and Track Days with Reed Kryder 2x a month. WW is for "Experienced drivers" and I have only been running in novice groups. I could probably run in an intermediate group without issues, but something about attending an event that calls out experienced drivers frightens me. The Reed Kryder events have novice, intermediate, and advanced, so that might be what I go to and work my way to at least intermediate before taking the plunge into Wonderful Wednesdays. Do you go to those?

Yeah these trailers seem to be a whole hobby within a hobby. At the track, I got more people talking about trailers and stuff they want to do to theirs than they would talk about their cars . Mirror is a great idea! This is super cool and now on my radar. Seems like that would be easier to deal with than setting up a tent. That is a really good tip I didn't really think about.

Trying to see where I might bump into fellow 7 owners. Where and who are you all driving with? I am located in Pittsburgh and would love to bump into some other 7 owners at track event. I am a newbie outside of the now defunct PittRace. I just ventured out to Nelson Ledges with Chin Track Days, which aside from cruddy facilities was a really fun lap and I will be going back. Now that I paid the Chin membership fee, I am thinking about attending their event at Summit main on July 4/5th. https://chintrackdays.com/event-details.aspx?q=5ZPP1Gu2V14%3d Anyone else going? Which venues are 7 friendly? I have noticed quite a few don't allow 7s - namely PCA. Chin actually doesn't either, at least in instructed novice according to a post for 2012, but somehow I was able to register and do an event without issue.

First track day this year and first time at Nelson Ledges

Thank you to everyone who helped me figure this towing nonsense and indulged me and my unnecessary long posts! Last weekend, for the first time, I towed my Caterham to a track weekend and now I think I can add my final thoughts, opinions, and experiences. Towing setup recap: - 2026 Nissan frontier with a tow mode button and Redarc Tow-Pro Liberty Brake Controller - Steel frame 7x14 v-nose tandem axle car mate avalanche trailer (2375# empty) - 1280 lbs s3 caterham strapped down over the wheels via floor mounted etrack with ratchet straps. - Tongue weight was right at 15%. - Standard hitch - no sway/weight distribution - Hitch and door locks. - Grip tape on the ramp doors My first towing trip was a hair over 2 hours, 90% highways with 70mph speed limits. The weather was not very good - windy and rainy. I keep speeds around 55-65mph to play it safe and improve mpg a little - you can tell the trailer is acting as a huge air brake the entire time. Through the seat of my pants I could feel some very minor bouncing as well as sway/movement from wind gusts and hitting standing water. Surprisingly, the most movement I felt was not from semis passing me, but rather SUVs that were going ~30 mph faster than me, which I did not really expect. Overall, it pulled fine and I would do a very long trip with a standard hitch without much thought. I do have the Anderson WDH, so I might just install it since I already have it. So I did a >2hr stint in the truck and it was so, so, so much nicer than if I had to drive the Caterham. I had heated seats, took a phone call, listened to music, and enjoyed a cup holder. I also could comfortable shoes. Pure luxury! I probably would have cancelled the event and been out a decent chunk of change because of the weather without this new setup. The weather was atrocious all weekend. It was raining cats and dogs. The car only got wet when I took it out to do some ice skating on the track and once when I thought it was clearing up and I was stuck in a classroom. It was awesome to have a little home base at the track to stay out of the weather as well. Being able to lock up the trailer after the track day gave me a nice sense of security as well. This weekend also made me think of a few things that would be nice to have outside of just the bare bones trailer. 1. An extended roof at the rear to let less rain in the trailer when the ramp was down 2. Maybe a tent of cover the rear ramp when raining 3. mounted paper towel holders 4. mounted clipboard 5. A little shelf 6. hangers for helmet/hans/gloves 7. maybe a hanger for the nose cone and hood
