Hi. Barracudas had a live rear axle, right? Ideally you want to add that to the weight of the wheels.
This is how I set my cars up for weight - if anyone else wants to correct me here, feel free - setting up car weight isn't clearly documented on racer.nl, this is how I worked out how to set up the weights so that the total car mass in the telemetry appears correctly, there's no guarantee that this is 100% accurate but it works for me:
You need to know:
Kerb weight of car (in Carfolio or whatever)
Weight of a full tank of fuel (AFAIK, I *think* Racer allows around 60kg for a tank of fuel, so you'll want to subtract this from your car's body mass)
Weight of the driver (AFAIK, Racer allows 60kg for a (very skinny) driver, you'll want to subtract this from the car's body mass too)
Unsprung weight - that is, the weight you enter for each wheel in the car.ini. As a ballpark guide, a 235/55 R16 wheel+tyre from the Jag weighs a perfect 20kg, a 185/65 R15 steelie from our Mondeo weighs 15kg, an old skool 185/70 R13 from the Capri weighs 13kg (yep, I weighed the wheels off every car we had here, I need to get out more ) . Ideally to that you want to add the weight of any part attached to that end of the spring/damper, that means the brake disc/caliper, the hub etc. Also, if you've got a live rear axle, you want to add half the weight of that too to each wheel's mass (a live rear axle from the Capri weighs about 60kg, on your car probably a bit more - so for the Capri you'd add half of that to each rear wheel mass).
So, you end up with:
Wheel mass = weight of your wheel plus any bits attached to the suspension on that corner. So, if on each front suspension you have a 20kg wheel you might then have a 7kg brake disc, 3kg caliper, 2kg for the hub, bearing etc. That would give you a total wheel mass of 32kg. for the rear you might have the same 20kg wheel but a 8kg brake drum assembly and half of a 60kg solid rear axle - that would give you a total wheel mass of 58kg for each rear wheel
Then your body mass would be:
Body mass = kerb weight - 60kg driver, -60kg fuel, - engine mass - total unsprung mass for all wheels (weight of each wheel/suspension, as above - wheel, brake suspension parts etc - in the example that would give you a total unsprung weight of 180kg)
Engine mass = Whatever you allowed for engine mass above
That *should* work out correctly I hope
