Interesting data.
70lbs on that load cell is about .006in of deflection? Deflection would be more interesting data than load I think.
Street tires on a street car……. That’s probably in the noise of perceived feel…….. a track car with slicks hitting the rumble strips on a track at 1.5G of cornering is easily several times higher loading. On the 914 I autocross on Hoosier A7s, we see 1.6 to 1.7 mid corner G loading with shock loading pushing that higher. That’s been enough to fatigue crack the car in multiple places so it’s not always about just reducing alignment changes but also about prolonging the chassis life.
If you get the chance to drive a 911 with an extensive cage in it, the feel of the added chassis stiffness is immediately apparent just driving around the parking lot.
