Does anyone know the unsprung weight for the stock rx8? I know this will vary on the wheels and tires but those numbers can easily be found.

Even better does anyone know the sprung weight front and rear?


Thanks!!!

Hmm.

Well you'd have to find the weight of your wheels, brake calipers, brake rotors, studs, lug nuts, brake shields, and control arms and that would give you an approximate unsprung weight number, then just subtract that amount from the total weight of the car for sprung weight.

Total weight distribution is like 51/49 front/rear so the sprung weight numbers will probably be close to the same over the front and rear.

There's a thread with a bunch of parts weight. It may help you find some data.

Thanks for the info so far. I was hoping someone already had this for the stock car. I might have to bust out the calculator and look up those weights.

Why you want to know? Just curious.

I thought the 8 had a 50/50 weight distribution?

Depends on how much gas you have in it.

Is that with or without driver?

I wanted to do some math .

A good web based example.

And my garage is really small, really uneven, and really cold .

I just wanted some rough numbers to play with.

I thought the 50/50 weight is just the car...without the driver and gas?

Just wanted to know, thanks.

2 year old bump, but yes I am curious about this.
My old Subaru had a ratio of sprung vs unsprung of 7:1 .
Has anyone done the math for the rx8?
