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.

Just Love this.... Read On!
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi + Cellular
Like knew and seems to have been powered on one time only. Apple treat it as a new device. Its spotless and works great. I have had several ipad pro's and decided to by this instead and I actually prefer it. It does everything I could do with my ipad pro 2020 and then some. Its faster, good cameras. The e-sim card works great though I do wish it had a physical sim card slow.. oh well! The battery life is really excellent, it was quick to set up via a transfer from my old device. I added a case that looks like a fancy note book and love it. This helps with drops and scratches. I have not added a screen protector yet. The storage capacity is the same as my old ipad pro, I will never use 128 gb anyways... To sum up, this gets 10 out of 10... and its a great replacement for a ipad pro!

Good quality, good price, bad shipping tho
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi
Honestly I was really happy with the iPad. The one I got was RENEWED in Excellent quality. I will start off by saying that it was poorly packaged during shipping and the iPad box was severely damaged, but luckily my iPad was just fine. The iPad came decently, but not fully, charged and was quick and easy to set up. The battery life does not last as long as my Galaxy Note 20 Ultra, but I am also sure I do not have it optimized for battery saving. I got this iPad for 2 reasons. 1) To be a pseduo laptop with a keyboard case for school, and 2) procreate. I am overall happy with the item. I'm just sad I found a better deal on the exact same model sold at Walmart and its in pink (;-;). The item functions well, and is as described, it was a really good deal

I purchased it to program Harley. Pretty nice
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi + Cellular
I've never had an Apple product before, the charging is slow, I love it because it's very light and durable I got it on sale So the value is very good. It's very thin also which I do like that and the collars are very bright and clear... I did drop it but from a low distance in the durability is great. Never damaged it a bit
