I've touched a bit of the AC manager and it's possible to fix the setup. I speak from memory, but I'd say you have to include an .ini setup in the server folder, modify it by deleting those setup parameters which you want to make adjustable (like brake bias for example) and load the setup in the manager file (plus assigning it to each car entry).As someone whose is hopeless at setup a fixed series would be interesting - but difficult to police. I'd assume you can still alter gears & tyre pressure. The Lotus 25 is a nice car and a series on Fat Alfies tracks would be fun.
