02 WRX Wagon
96 Impreza, 06 STI
I've been trying to come up with what gearset/transmission I want to use for Autocross and i've found this thread very helpful. FujiK, I ended up using the gear ratio's you posted on the first page to create a spreadsheet that allows me to quickly figure out speed vs. RPM for any subaru transmission and tire size combination. I have a 96' 1.8L Impreza Brighton which isn't listed in the OP, from the link above its the same as MY95 and MY97 1.8L's. I also have an 02 WRX Wagon with an RA gearset and PFGreen. I've been curious what my actual speed is, because between the gearset and enormous tires my speedo is way off. Anyway I took it a step further and made a couple charts that might be useful for people looking to upgrade their WRX Transmission.
