ZR1 center of balance ?

[xxxscimitarxxx]

I dont have room for a two post lift in my garage so lm going to fabricate a pair of inspection ramps..... 12ft long and 3ft high ....sketch attached.....errrr....not....will do so later

but with a tipping point calculated in the design to enable me to drive the car up the ramp to a certain point and then tip the ramps forward to get level

Question.......

where is the longitudinal center of balance at tyre level on a Z.....lm guessing somewhere just behind where the gear shift is but was wondering if this was a known spec

l could find it trial and error....and it would change according to fuel load....but the closer l know then the more accurately l can design the ramps

front to rear wheel base is 96''

LOL.....when are you guys going metric
