Anyone have data for the unsprung weight mass of an Evolution? I realize different wheel/tire combos will have an effect on the data but, at least it would be a good starting point.

I could weigh everything but, I figured someone must have done this before that wouldn't mind sharing the info.

 

lol I've got this too, all on the same sheet, I'll have this for you when I get the motion ratio. You looking for sprung weight as well then?

 

HAHAHA!!! Yes sir!

 

Here's what I got. Car was an Evo VIII, stock tires on a set of Advan TC2's (I think... my handwriting is terrible).

Cornerweights:
FDRV FPAS RDRV RPAS
953.7 850.5 600.8 617.3

Sprung weights:
860.2 757 513.6 530.1

Unsprung weights:
93.5 93.5 87.2 87.2

 

Man am I glad I found this thread!!!

I was looking for the unsprung weight at stock (though I have a IX, this at least gives me an idea...)

I'll get adding about 4lbs per corner and was trying to find equations to figure out how it will affect the acceleration, stopping, and turn-in; but I'm still looking for that stuff.

 

Deleted wrong thread.
