Heeheeehheeehee...huuhoohoohhoohaahaahaa!! aaahhhh..BOY!! I'm not trying to shit-stir everyone, but BY KRIKEY it's funny seeing everyone so mad over me spouting physics!

Alright hang on a sec, you say that having more 'dynamic' weight towards the rear is an advantage in accelerating, so why do you say that FWD has no advantage when braking when it has better dynamic weight over the fronts during that period?

Pfft.

You can brake seriously effing late in a FWD car and it can work brilliantly.

Almost everything else you said is fairly spot on.

Don't forget though, that as you 'accelerate' better in a RWD, you will lose more front end grip and hence start to steer wide due to the weight coming off the fronts - usually this isn't much of a problem, but again it's just more fuel to the argument that it's all a compromise.

The reason that having so much weight over the front tyres when braking is bad, is that you're using ALL FOUR tyres to brake. It's more effecient to have the load shared equally to maximise grip. Most FWD's will over-work their front tyres & brakes, leaving the rear tyres dragging around doing not much. Transferring weight rearward in a RWD while accelerating is ACE, 'coz it lets you get WAY more power to the ground.

As for the "losing more front end grip and hence start to steer wide" in a RWD" - yeah, totally agree with you. There's many RWD cars renowned for understeering horrificly under light-moderate throttle. Just hope that if you're in one of these, it's got enough power to kick the rear-out 2->5 degrees under heavy throttle, and keep on turning!! -At least this is possible in a RWD. In a FWD car, you've got to just grin and accept the understeer post-Apex. Crying or Very Sad

blluuurrrrggghh!!!! Mad

And Johnny: I'm not arguing the skill of FWD vs. RWD owners. I'm just stating the undeniable fact that RWD is the fundamentally better platform.

[/tit-tat]

I don't wanna hear who's Corolla can beat who's Falcon through the hills, or what time fellaX's integra can do at the drags. Just saying that RWD is less-flawed than FWD. Obviously 4WD+4WS with variable torque-split, electronic brake balance, 50/50 weight distribution etc. etc. is the ultimate, but who can afford a Nissan GTR? Really?

Sorry slushbox lovers, but the automatic gearbox is a toilet of a setup. Seriously!! I know that autos are usually quicker in RWD drag-cars with more than 1000hp, but I think you'll find most other race cars packing a clutch and conventional gears. Don't let me stop you from slurring your gears, just don't pretend that it's as involving as driving a manual!

-oh, I've raced Karts for 5 years, and i'm 1 1/2 years into a mech.eng degree. Not that engineers are the last-word on car or physics knowledge. We've had engineers sent down to the proving ground to do suspension revisions who didn't know what a suspension-bush was!! AAAARRRGGHHH!!!!! Shocked
