What do you mean by handling numbers?
Plus you'd have to take into account any combination of surface and weather/temp differences. Test a car on a 50 degree day on asphalt, then try testing the same car on a 85 degree day on concrete. It won't even look like the same car on paper. Then you have tire pressures, amount of tire wear on the tires, shock settings, sway bar settings...the list goes on and on. Sooo many variables. Like you said, too hard to say.Too hard to say, because someone would have to upgrade to those exact parts (not likely) and then do testing (even more unlikely).
before and after tests would provide a comparable set of stats.Plus you'd have to take into account any combination of surface and weather/temp differences.

I agree. I did 7 years of it in college.I'm not saying testing in general is "useless." I'm saying testing is useless if you don't keep variables constant![]()
