Yeah, Definitely.
Spot on Andy; the difference is simply a night and day improvement. I have nothing but good things to say about the shift kit.
Absolutely no downside with regard to normal light throttle driving, and when you want a solid shift; you've got it. Honestly; this is the way the car SHOULD be.
As both you & Craig have said; the difference is just compounded when you are dealing with greater than stock power levels.
Cheers, Dale.
