from what i know and heard, ver 1-6 GC8/GF8 can use ver 7 GD/GG Bugeye WRX & STI front shocks and springs, but using the rear shocks and springs would mean the rear will be higher and camber positive, so some modifications needed for the rear.

Same with ver 8 GDAC/GGAC WRX only i think.

ver 8 WRX GDAD/GGAD onwards i'm not sure, but i think maybe also cannot.

But ver 8 STI (GDBC onwards) is different because their are inverted struts and knuckles are different and not compatible anymore unless extensive modifications are made.

as you can see, the Impreza goes thru a gradual evolution. but looking at the performance in the WRC, they now need a revolution, just like mitsubishi...

Hi guys, am getting my next project car... It's a Civic EG (local) still
in its ori condition. Already has a B16A auto just transplanted in there
for the enjoyable DOHC VTEC experience.

Now shopping for a pair of good sports seats (Recaro, SSCUS, Sparco...
donno yet, all I know is it must be red colour :) and probably to re-
uphols the whole rear seats. Momo steering is a must item too :)

Any ideas on how to go next? Prob a K&N mushroom air filter to help the
engine breathe...
