You're saving up for the STi 6-spd tranny? A lot less work then ripping out the stock 5-spd to put in RA's or straight-cuts. Hah
Here you want launch control?

Actually the 6-speed is ALOT more work!
But RA gears still suck over 350whp, and for the price of a PPG or Mfactory gearset I mine as well go 6-speed. As even with the upgraded gear sets in the stock 5 speeds the shift forks still suck, the syncros still suck, and your going to blow that R160 rear diff apart launching. So yea, 6 speed and call it a day. LOL, you cant brake the 6-speed and the R180 rear diff.
The R180 was used in Z's, 240's, ect so thats bullet-proof and the 6 speed was co-designed by Porsche. lol. Many people are making over 500whp with all stock 6-speed with just a nice clutch.
BTW, I dont need a separate launch controller, my ECU can handle the jandle.
