Chris,

Check out the "Look Inside" feature on this book--"Lotus 25/33 by John Tipler. Appendix Two is there (well some of it not all.. blast it) and this appendix details each Lotus 25 and 33 chassis by race through the years.

www.amazon.com/Lotus-25-33-John-Tipler/dp/0750925949/ref=sr_1_1?ie=UTF8&qid=1389378311&sr=8-1&keywords=lotus+25+33#reader_0750925949


Doug Nye's book "Theme Lotus" also has a complete listing of the Lotus 25 and 33 cars by race as an appendix.  

www.amazon.com/Theme-Lotus-1956-86-Chapman-Ducarouge/dp/0947981098/ref=sr_1_1?s=books&ie=UTF8&qid=1389378588&sr=1-1&keywords=theme+lotus


You can use either of those as references to do your picture hunt. I was going to send you a picture of R4, but I think you'll find all you need.

[Chris Wright]

OK I think I've finish the Lotus 25 section, any inaccuracies, comments?

[David Lawson]

I haven't checked any of my references at the moment but a couple of comments off the top of my head.

The first picture of R1 with the T insignia isn't a test session it is from practice at the Belgium GP.

The aero screen wasn't introduced at the Britsh GP in 63, it was a bit earlier in the season as per the picture from the Dutch GP.

The screen at Monza '63 was a unique item being an original 25 screen with a small slot cut at the front rather than using the full aero screen.

The picture captioned as USA '63 looks like Monza to me despite the Stars and Stripes flag.

I think they ran a 25 rather than a 25B at Spa '64

Note the all enveloping mesh covering the engine intakes in the '64 Italian GP picture instead of the usual Lotus design.

Thanks David I will correct as necessary, thank you very much. I did notice however that the car on the Forum Header is the 1964 Spa car, are you sure it's not a 25b? notice 13" wheels and high mounted rear suspension points.

[David Lawson]

Chris

The header picture is from the Dutch GP when the car ran with 13" wheels on the rear and obviously with the 25B suspension.

For Spa Lotus took two Lotus 25s and one 33 (the chassis repaired after the crash at the Aintree 200). Clark practised both types but didn't like the 33 so drove his Dutch winning car converted back to 25 suspension and 15" wheels. I checked this information from Denis Jenkinson's race report in MotorSport magazine July 1964.

If you look at the photo Mark posted of Clark at La Source hairpin the top radius rod is in the lower location point at the rear hub as per 25 suspension. When you look at the photo of Clark sitting on the exhausts at the end of the race you can see the nearside radius rod at the lower location point.

Thankyou David duly noted and corrections made.

[David Lawson]

I know this particular thread isn't a general discussion one and is about adding information for each chassis but....

Just by coincidence I have reached the part of Cedric Selzer's excellent book where he describes the conversion of the existing Lotus 25s into 25Bs in the early part of 1964. I won't go into detail as Mark has ordered the book and I don't want to spoil it for him but it was a very complex conversion with the first one taking several days in the factory and involving a lot of "bodge and fit" with files and hacksaws and on a couple of occasions Chapman ordered a conversion at the track during a grand prix weekend which involved an all day job and more bodge and fit.

So different from today with the aircraft standard construction and complete corners of cars pre-assembled just in case they're needed.
