I don't need to go 60mph in first, but it'd be nice to be able to get there in second--especially when you compare the gearing to other sports cars with the same power/weight ratio (some of which in fact do 60 in first). The high speed gears look like a nice improvement, but I'm curious if the ratios wouldn't still be a bit too short...
I don't know your engine setup. I don't know your powerband. Daily driver you say. Want wider gear spacing? Do you have a V8 LSx swap?


Really you should be choosing the tranny/gearing what you're using the car for. You can't have it all sir. I find it that the long gears suit a lot of what people are using the car for here in the U.S.

Here is Ben's 20G xtr with long gears with a redline of 7000.

Here it is shifting at 8000rpms.

This is the car:


It's got a USDM STi AWD powertrain (with the USDM 2005 6-speed gearset ratios) but weighs a lot less. It's still got the stock turbo but has a front mount, custom full 3" exhaust, and AP custom tune. It's not that it's putting out that much power, but the fact that there's a lot less mass that needs to be moved around (especially since the STi powertrain is relatively torquey). I always felt the 6-speed in a stock STi was a bit shortly-geared for cruising, even more so in a modified STi, and especially so in a modified STi-powered car that's even lighter.

I think the high speed gears are probably great; it's just that on paper I can't tell if the ratio differences are enough to notice in my application? I know that an optimum gearing solution requires taking the exact powerband nature into account, but even just by feel, the car feels like the gearing could be at least another 30% if not even 50% taller and feel a lot better during its daily driving duties. I was just curious if there are any gearsets that might be closer to those ratio changes, as the high speed ratios are only around 6% to 18% higher (not sure what you meant by 'wanting it all'?).

Thanks-

The spec B's gear spacing when shifting at lower RPMs seems tight but when you shift at higher RPMs the spacing magnifies and is further spread out. If you're looking for a daily driving cruising gear set then grab a 5spd. Just know that it won't be as beefy nor well geared for what looks to be a performance vehicle built for track use.

I just hate to see a performance car dogged down for something other than what it was built for. That car in my eyes screams 8000RPMs 500bhp.

Thanks again for the info. I guess everybody has different tastes; I got this car to be an enjoyable and reliable cruiser and show car:


(I got this other one to be the high-strung, track-day beater/screamer...I can do the short ratios and 8000rpm redline with it: )

Okay so how exactly how would an 06 sti gears compared to 05 sti, 07 sti and the spec c gears. I have a swapped GC8 with 06 sti drivetrain and engine and alright it is great on the track it's a bit of a drag on the streets. I was going to make my L a project but I'm gonna make it my daily instead.

Run the ratios in the calculator.
