Yep, I absolutely agree with everything you said in that post
ESPECIALLY about matching gear and diff ratios to the powerband of your engine, something I think a lot of people understand, but..........
Unfortunately for most drivers on here, [i'm guessing that] we don't have the budget or the luxury to be changing gearsets to more suitable ratios just for the occasional trip to the race track Although I love circuit racing, and will take my car to the circuit as often as my wallet allows, I have to keep in mind that at the end of the day, it is still 90% a road car... And as a road car, I'd like as much torque down low as possible, as that's where my engine will be working for literally 80-85% of it's working life. That makes the decision to sacrifice the 50hp at 3500 rpm for 25hp at 7000rpm a little harder
But for the race cars like you deal with, it's absolutely true that a nice meaty 4000/4500 -> redline powerband and suitable close-ratio gearset would be ideal
