Welcome to the forum and thanks for posting this!

Bolt circle: 4 x 3.75

Are the hubs interchangeable between 3.75" and 100mm, or are they perhaps drilled for both so the studs could be moved? There seem to be far more wheel options at 100mm.

Also, what is the story behind the "rear sub frame modifications" on later chassis?

[Richard Buckingham]

thanks Mark, do you have numbers for how many of each have been sold that you can share?

Considering the unique, custom build nature of our cars wedo not release Ariel Atom 3 production volumes.

Regarding SRA cars, 84 chassis have been produced to date.
