Hey I was just wondering if you all really feel the Final Drive Gears are worth it, and about how much of a difference would i be expecting to see in my quarter mile time with it? Also I was also wondering if the Shift Kit was woerth it also, because I dont know that much about cars and dont really think that all that trouble for the shift kit will be worth it if it wont improve my quarter mile time that much. Well everyone please give me your input about this, is the final drive gears worth it? and is the shift kit really worth all that trouble and money to install?
