I have both B6 Screamer XL type (sounds like my ex?) and Caterham SV style Tillets installed in Caterham SVs at NJMP. If you need a Caterham S3 type Tillet then there are options nearby I could set up.

Making squeaks? I only do that to my passengers! Only one that didn’t squeak was @Vovchandr‘s better half @FasterThanVov. She is obviously used to going fast as a driver. @S1Steve did you squeak? Yes I have always used PowerFlex brand on my Caterhams since 2007. No squeaks ever. I always lube the bush before I insert (that does read vaguely ooo’errr). I always pull off the parts and use a press to do it properly. Ensures the polybush stays intact while fitting. If you look after your bush and lube well annually then polybushes last a long time. Still on the original set on my 2010 Caterham with no wear to speak of. Caterham rubber bushes wear and fail really quickly. PowerFlex USA sells all Caterham bushes out of PA. USA website. No squeaks ever!!!

Early 620s had a Watts Linkage. Phased out due to cost I believe. I drove the 620R Watts linkage in Portugal and Spain after it was first released (refer write up in library - track day report). It felt better than the 620S I am trying to sort now. Poly bushes are good for improving feel. You feel what a suspension is doing and not a couple of rubber rings providing artificial suspension.

It really is nice to read a post on USA7s where I get sent down a rabbit hole of offline research and thinking with the morning coffees and Bruce Springsteen on the record player. Thank you. To confirm (apologies if I missed this earlier in this long running thread) your use is primarily road with odd track day maybe? My initial drives are confirming what your data is suggesting. There is an odd feeling asymmetry in the front and rear under load - your spring rates are hinting at it. It’s not as well controlled as my UK 420R which was just the standard off-the-shelf suspension package. I’m changing to poly bushes all round and will test again as that makes it easier for me to feel what is happening.

Given I now ...cough cough...own....cough... a 620S.....(sheepish look) I am very interested in this thread. So...why are you changing shocks? Assume you must be changing springs as well at the same time? What poundage are you going to?

A couple of things on this article: 1) Aric Streeter is well known to me and is very much worth reading his substack blog. I don't always agree with his perspective but they are very well written and interesting and challenge your thinking. 2) The green car featured in his aero article was for sale last quarter of 2025 - it was listed on the weekly summary on a FaceBook ad. Have not seen it advertized this year. 3) I have seen the results of the MIRA testing and it is complicated. Aric does a good job in boiling it down for more ready consumption but there are nuances lost in making it simple for the reader. 4) His linking of aero to suspension needing to work together is a core lesson most people miss. They come along and shove a big wing on a seven and then never modify the suspension. You have to firm up the suspension to make the car work with the aero effects added. Even then I am wondering if he did not go firm enough in the front end with the 2.5" dip he discusses. More information than what he shares would be interesting to think through at deeper level. Tires have to be rethought, including pressures. 5) He expresses his ideas within a construct of aero whereas I have always thought of it and expressed it within the framework of weight transfer. Nothing wrong with that but sometimes the same ideas can be thought of in very different ways. 6) What is not really discussed in the article is how an effective aero package of a car requires you to profoundly changes your driving style. You now have to "trust" something you cannot see. You have to lift the cornering speed to make the aero optimally effective. Your operating speed range in a car within a corner becomes narrower as you have a minimum speed for aero to work and a maximum speed from the laws of physics. A lot of drivers cannot make that leap. I have done it but I do not enjoy it - its a far more intense driving experience plus I find my seat of the pants feel of the car on the limit is diminished/masked. Its not as much fun - at least for me. 7) Aero is should be applied intelligently. The Lotus 7 was originated in a period before aero. Why modify it for aero with all the compromises that entails when the smart option would be to go for a later design car of another type that leverages aero more effectively - less compromises and ultimately faster. This is a wonderful thought exercise but a poor basis for engineering a faster race car. There are more efficient and arguably cheaper ways to be faster.

Replacing which bits - rear axle, diff, something more?

Whats a Speedway rear end?

Can we pause and confirm the dry sump system first please? Caterham has been known to use three different types of Duratec dry sump - Titan, Cosworth and Raceline. I have even known Pace to be used in older applications. For an R400, I'd lean towards Titan being used. Is there a brand name on the underside of the sump? What type/shape dry sump tank is installed? I know our library does not have much on dry sumps but have you discovered the manuals available for download here to assist other issues that you want to address? It does not have to be the same year assembly manual as they do not change that much year to year. https://usa7s.net/ips/files/category/23-build-user-guides/

I think I need some time alone with those photos. hand laid carbon fiber body….look at that engine…

I want to wish you the very best on your project and send encouragment. Having picked up someone elses 'project' more than once and then made a go of it, I know how hard it is going to be. One thing you should consider carefully is the need to replace the wiring harness. Fires have a habit of giving them hidden damage. Since you have to strip everything back, this is a good time to change it over. The original owner was on USA7s albeit very low key. I am having a mental blank on his profile name. The car also appeared in the for sale section a few times - many in the long running classified ad post and there was a dedicated post from the owner trying to sell after the fire. I do not have any easy way of finding that - search by stalker in that sub forum and go listing by listing - sorry. As Bob @Anaximander mentioned on another page, there used to be a Brunton Stalker forum. The best bit was the owners gallery of cars so you work out where a stalker was in its evolution by chassis number and track down prior owners. Looks like its gone sadly. Maybe its still on the wayback history site - Bob may remember its original name? Bob also passed on Scott's contact. He and his father are good guys. Kit car building is a brutal business and there are bumps along the way, so not everyone will agree with me on that assessment. The Mineheart family know how to drive. A cheap air ticket to FL to see them autocross and chat between sessions will give you a world of ideas how to make Stalkers better and faster and learn how you need to drive it for its maximum potential.

Brutal Paul...just brutal. But I am pissing myself laughing

WE need a post on this build in the appropriate spot. Must include a hp number so I can feel superior.....

Yes I got the same email. It still relies on the seller being sensible and actually opening a negotiation with the highest bidder after the auction closes. The highest bidder cannot do this on their own. If they do not then there is no chance of settling an offline deal. That was my experience with the last time I was highest bidder on a Caterham on Bringatwat in 2025.

I've always thought of him as "CMuff"

Zero chance it would ever get plates in the socialist state of New Jersey. The NJ EPA would have a conniption. Its going to be Maine....where I want to retire to.

Ahhh...if you dive into the hundred photos you discover lovely floor mats: Quite elegant. I like the rustic look. Dual cruise controls on the back of the steering wheel is a nice touch: Matches the dual gear shifters Nicely fake background - matches what you would expect for a Cadillac owner. Pity they failed to eliminate the concrete in other photos and replace it with cobblestones These things really were a slab of old Florida. Pity the owner is dead and does not reflect in the side of the car when taking a photo. @wdb Well done - I really needed a good laugh. @JohnCh Why didn;t you tell me you were auctioning off your Cadillac? Did you keep the MAGA cap from the rear parcel shelf?

What am I missing? Need to see the owner for the real evidence of AI photo editing.

Yes this project has demonstrated lots of Artificial Insemination from a number of people over the years.....
