@JohnCh can they apply the logo to other items ? Basically I usually wear my kit at the track so I need long sleeves. I saw they had a long sleeve champion t shirt. Happy to take it up with 4th wall directly but didn’t want to run afoul of anything established. https://fourthwall.com/products/champion-long-sleeve-shirt-dtg

I am heading up to Lime Rock for a track day Monday 7/21/25. I think there are a couple other sevens going. Weather is looking good. https://www.motorsportreg.com/events/masstuning-trackfest-jul-21-2025-lime-rock-park-428632

a little cleaning and maintenance after putting some miles on this past weekend.

Wow. Learned something new. I didn’t even know there was a drain plug on the oil tank (new 420r). I have just been vacuuming the oil out for changes. Maybe I will locate it and just make sure it’s not leaking (haven’t noticed anything). I did chase down oil coming from the breather bottle at track days. It was blowing into breather and then right out the over flow tube and down the right side of the car. Pulled the tubes up (they were both sitting at the bottom of the breather bottle thereby negating its existence. Since I pulled them up I haven’t had that issue.

The fuse box cover just wedges in between the dash and the firewall. I added some duo lock to make it more secure. you can source these from caterham or maybe the importers. They are sided and differ on some models so just make sure you getting the right one (if you want to go that route). It has a hole cut it in that the 12v outlet goes into. https://caterhamparts.co.uk/fuses-relays/4389-fusebox-cover-for-rhd-eu4-175-model.html

There is usually a fuse box cover. Which you can order from the importers here. It has a stock cut in it (facing the tunnel ) that it slips into. I drilled mine out and added another outlet and wired in two switches that change the input from ign switched to contestant power or off. Which I find handy. the silver barrel one is the stock location and unit.

I have a brake light kit from @das76. It’s super easy install and gives you options for placement. I originally was going to put something on the upper rollbar but got nervous about drilling into the bar. The led strip might not be as clean an install as Bruce’s. But it looks proper enough (imho). (Note: I did have a led strip burn out a few leds but switching out the strip was easy enough). Great functionality with driving, turn and brake lights. I mounted mine lower on the vertical bars to make it a clean install and also to not be blocked by the half hood when installed.

Another caterham mystery. Most of the things I order are “out of stock” initially. I will tag it with an alert to email me when available. Most times within a few days it becomes available. But I suspect there is no rhyme or reason to it. I would think newer components become avail quicker. But it’s caterham so who knows. They are usually fairly communicative if asked.

Not sure how the dimensions may have changed over the years. But caterham parts has some options https://caterhamparts.co.uk/nose-cones/27-grille-nose-cone-s3-7-logo-grey.html?search_query=Grill&results=28 I ordered a replacement one which arrived in like 3 days after ordering.

The old PHP selector area strikes again. How are we to function in this mixed up world?

Factory mounted on the doors. But if you tell them not to install them there they won’t drill holes in the doors (not windscreen). There is a threaded boss on the windscreen already that will take the dprs. Just not 100% sure what mounting hardware comes from the factory and what dpr needs to supply. The windshield mount does keep the doors from opening all they way to the bonnet but it’s a trade off that I think is worth it as the mirrors are rock steady. central mirror - right. Forgot about cage. Yes that should work with dpr mount. And it will likely be more stable. My central mirror does vibrate/wind buffet at speed. Not sure I would ever easy zip the top and drive. Maybe trying to justify the ez in zip premium. Like I said I don’t really use the zips. But I think it looks good and maybe a time will come when I do use it. But if you’re keeping an eye on the budget maybe don’t opt for that. I forget how much the zip option added. My footwell doesn’t really get got. The new cars have insulation and carpeting so it’s not too bad. I did a run last weekend and it was close to 100 deg out. Cruising along wasn’t bad. I did sit in some stop and go traffic which wasn’t great but the footwell area wasn’t a standout problem area (it was boarding on unpleasant all around). I am reading the other thread about it. But don’t currently see any need to troubleshoot anything. vintage green with gray stripe and graphite pin stripes.

I had the dpr mirrors mounted on the lower windshield frame. Just make sure the factory doesn’t drill into your doors for the factory mirrors. I purchased some of the mounting hardware from dpr but don’t know what can be reused from the factory stuff. here is the half hood. I got easy in zips but don’t really use them to be honest. May experiment with opening then and driving like that for a bit if an open top half hood. I also mounted my central mirror a bit unconventionally down low on the windscreen. I actually really like it there. Your view is below the X in the cross bar and it doesn’t block forward view. Can be moved if needed. the brake light kit installed. They are low enough down so they don’t get blocked by the half hood. 6 point retrofit isn’t that big of a deal. Just have to figure out sub straps with the leather seats. Some folks just sit on the sub straps and they go thru the back of the seats. I had my squabs cut

Second @Vovchandr on aero. It wasn’t something that I thought about doing. But installing the bracket after the fact can be a pain (I hear). I added it just so that the bracket would be installed. Now I use the aero at the track exclusively. sounds like you are going to be road only (vs road and track) with the 3 pt belts. If you haven’t gone out on the track it’s worth a try. If you think you might go in the future you would likely need 6 pt belts (possibly dated per track requirements). I changed the mirrors to dpr before it even got delivered. https://parts.dpr-motorsport.com/contents/en-uk/d24 Added fuel gauge mod. And added 3rd brake lights from @das76 I also got a tunnel bag and 1/2 hood from side bits. Haven’t used the full hood ever. But the 1/2 has come in super handy.

Interesting read on the topic https://www.caterhamlotus7.club/forums/topic/57793-footwell-cooling-strategy/

I assume your current glass is a write off. But I was amazed at what the repair guys can accomplish. Granted I had a smaller crack. But the guy did an amazing job and said he could do cracks many inches long. before after I also added some window film ppf after this. It likely won’t stop a major event but small rocks and the general sand blasting should be protected against. You can get a bronco or jeep wrangler precut and just trim it down. sorry I know this doesn’t help with the replacement part of it.

Update Charles, I've confirmed that there is no stock for the rear tire at this time. Production is anticipated later in the year, but specific timing is still TBD.

Keeping an eye on options as I will be due to replace my zzs by summers end. Took another look at nova as they were taking over the Avon production. But hadn’t yet committed to producing the zzs and zzr line yet. Will update when he gets back but this was Ken Payne , North American manager at nova, response as of yesterday.

I have a 2023 420r. I had the coolant on the min line in the overflow. (Which some say should be labeled cold not min). After some miles and track days it drops just below the min line. Not sure where it’s going. I did have a small leak at the hose clamp on the radiator which I tightened and it stopped. Not sure if it’s just finding its resting level (slightly below min when cold). Or if I am actively losing coolant. 2 track days last weekend didn’t further reduce the level. But my expansion tank is never totally empty. Will keep an eye on it.

To all those who were considering it but didnt make it. You all missed a great weekend. Get your belts and cars checked and set up for next year.

i ordered these. But my installer actually put the eye holds in the floor which works but does create some interference with the bottom of the seat squab. I may switch it out at some point and would likely change to this hardware if I did it again. (Please do t take this as gospel - defer to the manufacturer). https://www.schrothracing.com/item/bolt-in-end-fitting-kits/hardware-Harnesses - this would still use the clip in hardware. Which gives you more flexibility on angles etc but creates more hardware under the seat (which may cause interference ) or this https://www.schrothracing.com/item/bolt-in-bracket-(b23c)/hardware-Harnesses this would direct wrap to it. Still bendable for proper angle.

I have the Schroth profi II asm set up. Love it. You can run 4 pt set up since they have the asm break away. But I usually just do the full 6. It’s reasonable adjustable (not a super quick endeavor but manageable). Since the one I adjust most is the passenger - I actually will move the seat which changes the length of all the belts at once. But the harnesses are fairly easily adjustable. 3” shoulder straps. But still hans compatible. Dated belts. (Mine they 2029) They do come with bolt in hardware. Mine has the eye bolts with clip in I have leather seats but have a cutout for the crutch strap. https://www.schrothracing.com/item/profi-ii-asm/fia-4-point-asm Schroth distro here in USA thru hms. Evan polisky helped me. But they have a few distro centers around the county. evan@hmsmotorsport.com I really like them and will get them again
