Do all MKIV's come with the traction control? I know the 97-98 do, but how about the previous ones? I think it's a must have because it keeps you from being all over the road in emergency situations sometimes. The traction control in BMW cars is a savior, and is great sometimes, so is the one in the supra that great?How well does it work if you were to have about 400-450rwhp? I know traction control is always advantageous, but will it be able to help with that much power? I'm looking around for a mkiv, and i think that that's the only question i have unanswered.
