Got another checksum. Sorry to do the Phil but can you remove all the 'data' folders for the cars on the server.
I've got my server running and so far I have found all that is needed is:

server/content/cars/example_car_1
server/content/cars/example_car_2        ;and so on for x amount of cars
server/content/tracks/data/surfaces.ini

So the checksum is done on surfaces.ini but none required for the cars unless a data.acd file is present.
Whether it's AC or sTracker, one of them seems to trip up on something if the car has a 'data' folder.
When there are data.acd files the checksum gets done first and you can't even connect to the server, unlike our troubles where the message comes up in red after we have connected.

silly question, but do we need to register anywhere for this or just turn up on the night?

Nah. Just make sure you have kept up with all the updates and jump right in the deep end.

.... BMW M1, & Porsche 930/76 k2g5....

..... Nissan,s central mirror & steering wheel not showing in cockpit for me....

Yeah the Nissan is not really finished yet.

@Phil.8 Could you please delete the 'data' folder for each of those cars from the server. i.e gr5_porsche_935_k2   &   gr5_bmw_m1

Ta

Oh. All the DRM cars are there plus a further BMW 320, the Ferrari 512BB LM, Nissan Bluebird and Kunos' 935/78.

Are these cars the same as the drm mod? haven't had a chance to try these out yet

Cars are weight for engine capacity as per FIA reg's.
Tyres, both graphical and physics are sized for engine capacity as per FIA reg's.
Tyres use compound and construction from Kuno's 935\78.
Tyre blankets set for only 50º
Power is scaled to weight, using an arbitrary algorithm.
Aero drag is scaled to weight so the lower powered cars can still reach a decent top speed, using an arbitrary algorithm.
Wing(s) drag/lift is the same for all cars however the placement matches that of the model. Each car will have a different aero balance.
Gearboxes are free, you have 46 numbered gears and a couple of dozen diff ratios to choose from. Each car has either 4 or 5 gears as per real life.
Brake torque is scaled to weight, using an arbitrary algorithm. Max pedal should lock-up at most speeds as per real life.
Steering ratios are scaled to wheelbase, using an arbitrary algorithm.
Fixed colliders from DRM mod as they didn't work with 'car radar'
A few low res textures tweaked.
A few models tweaked, back faces, unneeded things etc.
Disc glow added.
Real names, although accuracy is not guaranteed.

All of the above is still a work in progress and subject to change.

Will run beside the DRM mod if for some reason you want to keep that, such as pick-up racing online.

 

Too good to be true, now it appears the M1 is invisible.

 

And after a small change I got kicked from my own server too!

This is not meant to happen. The data folder hasn't been encrypted so no hash check should take place.
All the other cars seem to be happy and the F1 75 worked as well this way. I'm rapidly running out of ideas.
