Hey guys,

I was wondering whether the 5 speed WRX community (sorry STi owners) would be interested in a gearset similiar to that of the ratios in the 5 speed STI RA gearset but at a price range of 800 dollars with similiar or greater gear teeth strength. I know alot of us back down from the full STi 6 speed tranny due to the extremely high price and alot of us back down from the RA gears as well due to an average price tag of close to one and a half grand. Also, which final drive would you guys choose? The stock 3.9, 4.1, or a 4.44? If needed, check out the chart on Rallispec (http://www.rallispec.com/Subaru%20Gear%20Chart.htm) but it only offers a comparison between the 3.9 and 4.44 final drive. Lastly, I was wondering if anyone would be interested in a conversion kit to change their 5x100 wheel hubs into an STi spec 5x114.3 hub. Just wanted to say thanks in advance on those who participate.

thx

Please reply guys

 

If I don't have the money for a 6MT conversion in my WRX, I'd get the RA gearset with cryo treatment professionally installed. If another gearset offered similar ratios with the same or better metallurgy for less money, of course that would be the way to go as long as there was some sort of guarantee on the quality.

I would stay with the factory final drive ratio for my daily driver. Lower final drive (higher numerically) would kill my highway fuel economy with little benefit in performance, at least for my purposes.

I'd also stay with my current 5 x 100 bolt pattern. There are plenty of aftermarket wheels to choose from for my application and I don't need any additional wheel retention from the wider spacing of the lugs.

what he said^

 

Someone who autocrosses their 5MT-equipped cars might benefit more from higher numerical final drive ratios combined with the RA gearset. Since the RA gearset has less 1st gear torque multiplication, a higher numerical final drive would gain that back and make 1st gear more usable for tighter courses.

The same goes for drag racing except that there might be a need to further decrease the RA ratio spread from 4th to 5th gear, as many modified cars would see a need to shift into 5th before the end of the ¼-mile with a higher numerical final drive. As vehicle speed increases, so does the aero and rolling frictional drag on an accelerating vehicle. Keeping the engine RPM in the 'sweet' spot of the torque band puts greater importance on gearset ratios at higher vehicle speeds.

For my daily driver, I could live with the RA gear ratios combined with the stock 5th gear ratio to retain highway cruise economy with the stock final drive ratio.
