I saved half an inch in the transmission tunnel by using 1" x 1/2" tubing instead of 3/4" square.

Lotus and Caterhams come is a range of sizes. I think I remember the Book chassis is the same size as the Caterham SV chassis.

Take a look at my tunnel -- the top rails can be moved inward. I reclaimed a couple of inches that way in the thigh/butt area.

Seriously go take some measurements from the Miata as far as that seat area width. I don't think that most of our builds are that far off?

There are the Saturn sports cars amendments to the book plans as well. If you do not have these PM me and I will email them to you.

Also, I had been wondering why many locosts look to me a little different than a Lotus Seven around the cockpit area. I think it may be that the Lotus scuttle is farther back than cars with the book frame, making the locost cockpit look more wide open. The only Lotus Seven drawings I could find didn't have that dimension, or the drawing was at such low resolution that I couldn't make out what the drawing says.


There are a number of differences that add to the differences when you look at them

Besides dimensions these are common differences that get skipped in constructions but stand out

Scuttle being further back is one of the most jarring.

Vovchandr, thanks for the pictures of the differences. If I pull the trigger on a build I plan to incorporate those features. I'm trying to wrap up a lot of work on my TR6, then I'll decide what to do. I have a new "problem" in that I'm getting V6 fever after watching a video of an MK Indy with a Mazda V6 in it. It sounded so good, and more horsepower than the Mazda 1.8, and lots more torque, as well. I'm looking at the 3.0 liter Ford 60deg V6. It looks like a good fit. An old Ranger pickup with that engine has just the right width of rear axle. I haven't looked at the Ranger spindles yet.

The originals have the driver sitting more rearward, noticeably somewhere between the tires. And the dash comes wayyyy back.

Did I mention once that getting into an original Seven was like getting into a kayak? Maybe a sleeping bag w/o unzipping it?

I've seen an original 7 close up, I think I would have to use Vaseline to get into it, but that's just me :lol:

Instead of the ranger spindles, I suggest using 80’s ford full size or Lincoln towncar spindles and brakes.

There is a builder here who used the same engine but replaced the upper intake with a carb mounting plenum (it never came with a carb or tbi):

There is also a builder here who adapted early ranger spindles to work:

Thanks. I looked at all of these links and learned a lot. The cam adjustment feature of the Lincoln spindles looks good.

I like those adjusters too, along with the unitized bearing with slip-on rotor, better caliper slides, etc but the earlier 80s spindles are much shorter and fit better on a locost.
