2004-2021 Subaru WRX STI 1st-4th Straight Cut Gear Set by IAG Performance
Gone are the days of blowing up stock six speeds, or having to resort to race-only solutions to support the high power levels that built Subarus now produce.
The IAG-Spec PPG Straight-Cut 1-4 Synchro Gear Set is designed for weekend racers (and weekday racers for that matter) who prefer the streetability of a synchronized gearbox which is suitable for daily driving. The kit features strong, straight-cut gears (vs. traditional helical gears) which provide maximum performance and durability for high horsepower Subarus and can be safely driven on the street.
IAG engineers worked directly with PPG to specify custom gear ratios which allowed us to increase top-speed in 1st and 4th gear. This change will prevent extra shifts while drag racing. Additionally, the gearset is designed to utilize the OEM 5th and 6th gears for quiet highway operation and maximize streetability.
While the synchronizers improve drivability for the street, the taller 1st and 4th gears are the stars of the show when it comes to racing and all-out acceleration. A 1st Gear Ratio of 3.077 results in an 8-10 mph increase vs. OEM (years vary) while the new 4th Gear Ratio of 1.042 will ensure that you finish out your quarter mile pass without shifting to 5th.
Sub 10-second street Subarus are all the rage right now. The partnership between IAG and PPG combines our experience to offer a robust but versatile combination that appeals to those who want the strength of a built transmission, but don't want to give up driving the car on the street. Pfitzner’s legendary strength and durability paired with IAG’s insight on gear ratios and specifications has resulted in a product that we know will be a game changer in the Subaru community.
