am seriously considering a 1998 to 2000 gs400. I have drove a couple, and loved them. I just never tired to see in power mode with TC off if it would spin on dry ground. The reason I want to know this is with that much power i would think it would have a traction issue. Also with other cars that i have drove with traction controll it seemed like it really slowed their 1/4 mile times down. Does it do the same or really make it faster? Just let me Know how most of you all get all she's got out of her.

 

Traction control slows it down because the second it detects wheel spin it completely shuts down for a second to regain traction ... Best bet is to turn on ECU power, turn off VSC and practice brake torquing and different launching techniques ...
