You are assuming I have not already done it a few times.
Im not speaking from inexperience here I have set up a couple of track cars with it before and seen the results.
I suggest you try the haltech with traction control setup you will be suprised at the results. If you set it up right you barely feel it.
If you just boot it and let it do all the work then yes you will feel it, If you come off a corner and are also trying to control wheel spin you dont actually notice it working in the background. you just dont get those flares in wheel speed anymore as you are feathering the throttle.
I agree the std traction control is way to aggressi ve in its settings and does kill the car, that is the way its setup in the computer not the fault of traction control itself.
Is it worth it on the street well I guess that a choice every one has to make
I think it is for when you are doing a mountain run or something like that, ie helping with power down off a corner.
