Default weight distribution numbers?

[Starfirebird]

Ok guys i have a question and maybe you guys know the answer or where to look.

Here while back i seen in one of the tuning garages someone mentioning default weight distribution #'s.The only one i can remember is FF which is 70/30.

Would anyone by chance know what the other figures are?

FF is not generally 70/30. It depends of the car, and of the weight stage reduction. Some 4RW are 60/40, some are 40/60.

I'll give you a self-made-proven-by-experience method for any car with flat ride heigth (0/0, -20/-20 or +17/+17... Whatever, same digits) with no weigth reduction (that's important)

Click on "default" in your suspension setup. Notice the front and rear spring rates.

Let's say it x kilogram for front and y for rear.

x + y gives 100%
x / (x + y) gives you front %
y / (x + y) gives you rear %.

Your car will be generally like x / (x+ y) % / y / (x + y) % unless Polyphony made a s****y default setup.

With weigth reduction, you'll have to adapt this with logic and driving feeling.
For example, on my Citroën 2CV setup (yeah... ), I know the car irl, and I understood what they removed to make her ligther.

This formula doesn't work for RR cars, of course.

"Oh my god !" => you're welcome... This is capital but not the best of my tuning secrets

It really depends on how well the car was made. Cheap eco FF cars are most likely 70/30, while high performance cars try to maintain as close to 50/50 as possible.

Thanks.

I will be putting that in my notes for sure 👍

Generally, they'll be within a few points of these values:

FF: 60/40
Front engine AWD: 60/40 (FWD based i.e. Evo) to 55/45 (RWD based i.e. GT-R)
FR: 50/50
MR, mid engine AWD: 45/55 to 40/60
RR, rear engine AWD: 40/60
