WRX vs STI

[PhyrraM]

All STIs in North America had a 6 speed with some type of front LSD.

Outside of North America, STIs before '01 had 5 speeds with, or without, LSDs. IIRC, most are without. '01+ had 6 speeds with, or without LSDs. However, the vast majority of 6 speeds did include an LSD of some type.


Also, in North America, NO 5 speed came from the factory with a front LSD.

The '07-'09 Legacy spec.B had a version of the STIs 6-speed, but I do not know if it came with the LSD.

As long as the suspension is designed properly, a LSD will not be needed until HP reaches 'ludacris speed' levels. The first Elises did not use one and were greatly praised for the handling and power delvery.
