I don't think this thread has enough hostility yet. I'm inviting Carlos. . . stand by. (I may regret this. It's sort of like releasing the Kraken.)

Besides, 47/53 isn't exactly what I'd call 'tail heavy'

Ok, I was wondering when we would get to this. First with all the aluminum I have up front --heads, intake (plus stuff removed) I would have even less on my front tires.(all the stuff I removed lifted my spring height 1 inch)

Ok, slightly positive camber in front with as much caster I could get into it.

Negative camber in back, plus over size tires and a sway bar.

Yep, this all makes a difference in an OLD C2 that gives the newer cars a real bad time on the twists!

Now, if I only had some brakes.

I like Carlos. I welcome his input.

Out of curiosity, what mystical life force differentiates a FRWD with say 45/55 and RRWD with 45/55 all other things being equal? We're controlling for weight bias (and punting on mass centralization a bit).

I totally agree, although his philosophy sounds great, physics is what really matters.

I feel like I'm in a trench and you just announced that you're throwing a grenade in here. We may learn a valuable lesson, but at what cost? At what cost Ben?

I went to bed at 7:03, then still had to wake up for class. Beat that!

Better you than me.

I went to school at one time. I know how tough it can be.

Unlike me, I know it will do YOU some good.

I know you will make the best of it.

There is a lot of miss information here. I'm on my blackberry so bear with me. There are obviously a lot of factors, but let's focus on the ones that are most pertinent. Let's talk about center of gravity, polar momentum, and corner weights. The center on gravity of a car is actually three dimensional. It is a point in the X Y Z axis of the car. For this discussion I will be referring to X or longitudinal axis. The moving the center of axis forward or aft will change the ratio of effort that the front and back wheels must do to rotate the car around it's COG. Polar momentum is a function of how hard to rotate the car the closer the mass of the car is to the COG the easier it is to rotate. Corner weights are affected by the COG and the overall car weight. Corner weight are the amount of force applied to the tires. As more weight is applied the greater they grip. let's apply this to a corvette. It has a slightly forward COG with relatively high polar momentum and has perfect weight distribution. Read a magazine and you would believe that it oversteers, that's flat out wrong. C6 understeer! They have tons of torque so if you rape the pedal it will step out, but driven correctly you can go flat out very early. Most vettes races run almost square tires. I run 275 fronts and 295 rears. The car is corner balanced 50/50, but before my new rims (245 fronts old) I Rand slight front heavy for more front end grip. Remember that changing corner weights changes the force applied downward to the tire, but does not change the polar momentum or the amount of grip required to move the front or rear. if you can drive then you are consiously managing the shifting weight of the car to make it turn in track out slide whatever.
