The best 0-60mph I ever managed in my old ED30 was 4.4 seconds and that was with......
Toyo R888 semi slicks sticky rubber.
Quaife LSD
Anti-lift kit
Bilsteins
A cool dry day
Stage 2+ hardware
Mapped DSG and launch control
100bhp/130lbft shot of nitrous injection!
So, 440bhp/510lbft and still 0.7 seconds slower than what the OP claimed!
Good laugh though!
Now 4WD is a different kettle of fish!
