I have noticed this and you can do a couple of things about it. One, you can lower the brake pedal. Or two, you can get one of those aftermarket bolt on pedals that just bolts on top of your current ones and just use the gas pedal. It will raise your gas pedal up maybe 3/8ths of an inch and probably make it a big larger too. Much easier for heel/toe downshifts.
That applys to every car I've ever driven, no more so on MKIIs as far as I've noticed. I don't think anyone would make a mod for something like that, and it would be pretty hard to do yourself without just strapping on some blocks of wood.
