420....
ain't it a bit... aaah.... too much? For FWD, that is?

....I'd be inclined to agree, even without the benefit of registering on the linked site. Wheelspin in 6th anyone?
Its all about throttle control! 
....Yes I know how important throttle control is but 420 for everyday road use isn't very practical, or should I say comfortable, is it.
Huh - I don't get that comment.
The harder/further you press the throttle, the more of those 420 horses you release. If you don't want all 420 chomping at the bit, don't press the throttle as hard. It really is that simple - and is what makes Lewis Hamilton such a god in the rain, yet muppets like Raikonnen (Spa) and Massa (Silverstone) can't handle.
The only time those extremes would be un-managable is if you had a shyte map, which gave massive amounts of boost (therefore massive low down torque) at very low revs, rather than a better map, which increases the torque on a progressive, linear and predictable basis.
....And I don't get your comment, T-T - I actually agree with you about the importance of progressive use of the throttle but I'm relating 420 ponies to FWD in the real-world environment of everyday driving on UK public roads - It's not impossible but just unreliable and uncomforatble in some everyday circuumstances - IN MY OPINION!
