Do you mean factory wise, or general wise? If incase you meant both...
Though thats physically true, your statement, I don't know.. I havn't seen anything THAT impressive out of factory MR cars that makes them standout by their unique drivetrains. RWD cars do things just as good if not better from my experience.
Uhmmm... The Porsche Boxster... which has become the de facto point of comparison for moderately priced sportscars. Sure, sure... it's not the fastest thing on four wheels, but the balance is good.
The Ferrari 360 and 430. Again, the de facto point of comparison for sports cars in their price range.
The Porsche 911... though it's rear-engined... it has some of the advantages of mid-engined cars, though the extreme rear-heaviness had to be corrected through a number of suspension geometry measures... including moving the front wheels back from the front of the car, to remedy the weight balance somewhat... which also gives the 911 a ridiculously short wheelbase for its size.
Then there's the Toyota MR series... the Porsche 914... the Audi R8... the Ford GT... the Lotus Elise/Exige (probably the best example ever of proper dynamic balance)... and so on and so forth.
Regular high powered front-engine rear drive cars simply can't match an MR or RR's traction off the line or out of a corner, not without some specific engineering to move the weight to the rear. That's why rear end gearboxes are starting to become more and more popular (though they're nothing new). A regular FR car will be front-heavy
unless it's designed especially not to be. Which is why BMW uses aluminum for its front ends and steel for the rear... to shift the weight balance.
An MR car doesn't have this problem. It's naturally 50:50 or even 40:60 or whatever. Slight rear-heaviness, in fact, is regarded by some as superior, since this reverts to a 50:50 balance under braking, which is important when entering a corner.
I'm not a fan of fwd cars, in the game or real life. Even though I own a fwd car in real life.
I'll have to disagree with fwd cars being better balanced. In fwd cars, the engine is at the front, as well as the tranny and driveline, making the car nose-heavy.
Rwd cars allow the engine to be mounted farther back from the front wheel, resulting in better f/r weight distribution. In some cars (Corvette, some others) the tranny is also mounted at the rear to give even better f/r weight distribution.
Fwd cars have other disadvantages, traction, tire wear, etc.
I agree with the traction and tire wear... but then, I said as much last post.
But I never said FWD cars are better
weight balanced. What I meant is that modern FF cars can be given the proper dynamic balance with good suspension design. Which is how a Mini Cooper S can have less apparent understeer than a BMW 3-series... or how a FWD-based rally car like the Evo can be "pointier" on track than a WRX with a better weight balance. Something which is often remarked upon in real-life by testers, and not really seen in Gran Turismo 4. Like I noted earlier... in the game, the Subaru's better weight balance is accurately reflected, but the Evo's suspension trickery that allows it to point into a corner better isn't.
Yes, nose-heaviness is an issue... which is why MR cars are technically superior to FF or FR cars... and even by moving transmission parts on FR cars to the rear or adopting the new FR-midship approach, FR cars are still not quite as quick, out-and-out as an MR car... but you can get around it, also...
You can't quite make an FF car as quick as an MR car, but by good suspension design, and by using a shorter wheelbase (as in the case of the Cooper, and, in fact, most "hot hatches") combined with a trick suspension, you can make an FF car turn on a dime... heavy nose or not... and getting on the gas will kill the oversteer, just like in an AWD car... which makes cheap FF cars great for JWRC. They're quick, nimble and... well... safe.
The old MR short-wheelbasers were even better... but they had a tendency of killing drivers.... simply because all they do is oversteer. Snap-over on the brakes... snap-over on throttle-lift... power-over on throttle-application... oversteer due to the mass of the engine behind the driver... oh... they were fun to watch.

Anyway... it's all relative. I've driven FF cars that felt as good as FR cars... FR cars that felt worse than FF cars... and FR cars that felt as-darn-it-good as MR cars (the damn Miata feels like a go-kart... wonderful little thing)... it's all down to the actual design of the car and the suspension. Endemic understeer is a problem mostly of specific suspension design and tire technology... it's not inherent in drivetrain type. Which is why EVO magazine regularly features hot hatches, and why road testers went gaga over the first generation "New Mini"... because these cars are designed to allow tail-out fun. Something that's rare in new cars nowadays. Sure... you can't power-oversteer these little beasts, but there's a lot more joy in getting a corner right than in doing parking lot donuts... though I still enjoy doing the occassional donut or burnout.
Most people who pooh-pooh FF cars just simply haven't driven the right one yet. Give it a chance. A new Mini... an Integra Type R... a Protege... an old Nissan SE-R... or any of the numerous "hot hatches" from Peugeot or Renault. Don't overdrive them, though... set up for the corner, give it a flick, a dab of the brakes, and enjoy the ride... not on public roads, though.
As for superchargers.....World War 2 called, they want their technology back. 
Stock power, and a Stage 1 weight reduction puts it to 996kg. 
Stock weight is 1060kg. I just checked the stats then.
BMW have now done a similar thing with their 335i twin turbo and Mercedes are jumping on the bandwagon too. A mild boost increase (around the 0.4bar/6psi. range) with sensible driving allows the motor to get that bit more power but be able to basically 'recycle' previously wasted unburnt fuel dumping out the exhaust by running it through the turbine, compressing it up and back into the motor.
RWD spins out at the first sign of throttle.
