No, I checked that and they aren’t pushed in so all is good -
Please could I take the 2.4 steering rack?

Looks nice, hopefully the paddles aren't pushed either or they'll drain the battery in storage - Today

Been waiting since December for this one, but well worth it. SBFS Steering wheel bag, takes my modded 250 very nicely, snug, but doesn’t activate any of the buttons so it is ideal. -

Keeping fingers crossed it’s a dry day -
Treated the tin top to a full valet Thursday at my favourite hand car wash. When it was done, I climbed back inside and found this air freshener hanging from the mirror: Getting a bit paranoid that I’ll be done for double copyright infringement.

A little teaser of something in the pipeline.... The XI was a pig to start, but once running it performed admirably . -

Most of the documents I had seem to have been lost to time, and a major (home) server crash 15 years ago, this is one of the surviving bits of info I have from one of the independent Caterham tests; sadly I can't remember who from, to credit them, not could I find it still on line in just a quick Googling. For those interested! (Obviously, this all pre-dates the fluid analysis modelling that's been done over the last decade or so!) " From Curborough Site I was lucky enough to have my car selected for the test session. Following various conversations with Graham Kendall, who not only manages the Wind Tunnels at MIRA, but also competes with daughter Claire (yes that Claire) in the rapid Metro, I prepared a few add on devices in readiness for the limited time available for the structured tests in the Wind Tunnel, whilst some other lucky club members had a tour around the facility. Apart from the obvious Caterham design I had added a full flat floor under tray and rear diffuser. Previous theories on airflow meant that I already raced with the front number plate mounted low down on the front of the nose cone. Yes I know you are all asking, "Why on earth would you want to do wind tunnel tests on something as un-aerodynamic as a Caterham 7?" Well even though it has the aerodynamics of a brick, there are still very useful things that can be accomplished using a test facility such as the Full Scale Wind Tunnel at MIRA. Armed with a multitude of cardboard cut outs and tank tape I was aiming to reduce lift on the front axle to balance the car and hopefully improve the drag at the same time. The first series of tests consisted of a splitter below the number plate, an additional spoiler below and blending. I won't bore you all with the full technical results but in summary these changes actually reduced aerodynamic drag and lift at the front. The action of reducing front lift actually increased rear lift by pitching the car around its centre of gravity. The next areas of attention were the front cycle wings. The theory was that air flowed both above and below the wing surface acting exactly like the wing of a plane. This caused a depression on the top surface relative to the air below causing lift. Blanking off the gap between the wheel and the wing did indeed reduce lift and drag, but without increasing rear lift. These results were further enhanced with the addition of a low sharp edge towards the back of the wing in an attempt to trip the air up and not follow the contour causing depression. At this stage CD (drag) had been reduced by 3% and front lift decreased by a whopping 14kg. How could I not resist looking at the front suspension? Now obviously I couldn't remove it all so I made covers for all the exposed round section tubes to change them to pear drop section. Although improvements were made, they were nowhere near as big as the effort in making the new sections! Another few kilos of rear lift were lost by adding wheel deflectors to the lower edge of the rear wings in front of the rear tyres, but at the expense of a little drag. Then came the addition of side skirts to the car. I set these to give ground clearance at all times under racing conditions. These had an overall reduction in lift of 9 kg but a slight drag increase. As I stated earlier I had already fitted a very pretty carbon fibre rear diffuser. However the shape of this was wrong based on textbook theory. The MIRA experts decided it was not long enough and the diffuser angle was nowhere near the optimum range. Copious additions of very stiff cardboard went some way to correcting this situation. But no matter what we tried, the best solution was to consign it to a very large skip! (The diffuser, not the car!) From a suggestion by one of the group present, we also added additional blending profiles to the windscreen posts. Although not strictly legal in my racing class, it did improve drag very slightly. Lastly for amusement I removed all of the weather equipment (roof and doors). This increased the drag force through the proverbial roof requiring a further 10bhp at 100 miles/hour, but actually created some more rear down force. I would like to thank Graham Kendall, Ivan Starkey & Paul Atkin for making this very interesting visit happen and for the opportunity to complete these tests, which sadly I have not had chance to convert into road/race-worthy modifications." -

One of the issues that's been found, on the couple of wind tunnel sessions I know of, that used Westfields, (and kind of backed up by one I'm aware of that used a Caterham) - all a long time ago now, was that the cars had a lot of nose lift at speed. ANd that the common practice of flat flooring or adding a diffuser to the back of the car, while some what beneficial at that end, could effectively exaggerate the front end issue! Interestingly, one front end treatment to reduce some of the lift generated, that was found in both Caterham and Westfield based testing, was the ducted in radiator, with it's air flow exiting on top of the car and away over the bonnet, and not just generally into the engine bay. Both marques introduced ducted noses, though arguably Caterham got the form and packaging much better, as far as fitting the actual cooling packs inside went. (It's the same testing, that on the Caterhams led to the development of the "CSR Style" front arches, to manage airflow at the front wheels. Though practical realities stopped them being able to go as far as was really needed, I believe. -

Very impressive @Davemk1 we look forward to seeing the update after you've tested at speed. I really like how you're incrementally improving your car for it's task. -
I can take some this morning
