Wow! Those are some serious numbers! Since I'm not taking it above 85mph, the specs for 115mph don't worry me - though very interesting to see. I guess it's a non-linear curve, and I can plot the 2 points and guestimate any effects at 55mph.
But here's my question - which of the above situation is the best for, let's say racing or drag racing? I understand less lift in the front gives you more stability (better control over the steering wheels), and downforce in the rear gives you better traction - especially important at high speeds when the rear end can get squirrely on you.
With the front only setup (like I'll have soon for a month or 2), I should expect no difference in the rear traction at speed, but better response from the front tires. (?) When i get the rear put on, I'll lose a lot of the benefit of the front spoiler from having no spoilers at all, but I'll gain a lot of rear traction?
Let me know if I'm wrong, or not thinking about this the right way - I'm not exactly an engineer.
