I've searched and can not find anything, i f anyone know what it is I would really appreciate it so i can finish my design project. tbs From a couple other cars I've modeled, a stock 280ZX CG height would be between 24 and 28" off the ground.

roger280zx Posted May 25, 2010 Share Posted May 25, 2010 Somehow I knew you could answer this one johnc. How does that compare to the s30? Quote Link to comment Share on other sites More sharing options...
johnc Posted May 25, 2010 Share Posted May 25, 2010 Somehow I knew you could answer this one johnc. How does that compare to the s30? Probably about the same. Please remember that the above are guesses based on a model I have of a E36BMW and my 350Z. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted May 25, 2010 Share Posted May 25, 2010 Didn't Richard (260DET) have some Nissan literature that said it was basically right at the shifter hole in the transmission height wise and fore/aft on the 280ZX? I think that would be a lot lower than 24". Quote Link to comment Share on other sites More sharing options...

I think that would be a lot lower than 24". Shifter hole to ground on a stock 260Z I have in my shop right now is about 22". The E36 model we ran through WinGEO3 was a F Prepared autocross car running 15" slicks and weighing about 2,100 lbs. It came in with about a 19" CG height with a modeled 150lb. driver in the car. 24" might be a high estimate for the 280ZX. My 350Z comes in at about 21" with the same modeled driver in the seat.

ckolander Posted May 27, 2010 Share Posted May 27, 2010 So based on me weighing in at 260, my CG is shifter height somewhere in the passenger seat?? lmfao Quote Link to comment Share on other sites More sharing options...
Black S130 Posted January 30, 2018 Share Posted January 30, 2018 I know this is as Old as Methuselah but i found some info by the NHTSB and it stated that the CG for a 79 S130 chassis had a CG height of 19.25 inches and 45.5 inches measured from the center of the front spindle to the rear of the car.
