TUNING A WRX STi - CAN YOU RID SUBARU'S NEW WRX STi OF ITS UNDERSTEER AND TORQUE ISSUES? MRT AND WHITELINE HAVE A CRACK

摘要

One of the complaints levelled at the WRX STi has been its lack of bottom end and mid-range grunt. You're wasting your time if the 2.5-litre turbo engine is spinning at less than 3000rpm, but above those revs, power builds steadily until about 6500rpm. Gear selection is critical, because you need powerful drive from the rear-biased AWD system to make up for the frustrating turn-in and mid-corner understeer.
