The SL is about 200 pounds heavier. And what SL is that (yr)? Where did you get that info? How much gas was in the car, we have 20 gallon tanks... That's at least 200 lbs. Did the driver powershift? What rpm's did they shift at? How many miles were on the car? of course I have enough power off the line. LSD's are one of the most common 3kgt mods, cuz we can't give it full power till 2nd gear by the way, the 3000GT is not a sports car. It's a Grand Touring car... I love goin 100+ and it feels like I'm crusing at 45... while your 240sx is shaking like crazy. Dog, your the last one to be calling bullshit.
