Not bad at all. I'll bet that simply installing a good set of tires instead of the factory compromise specials would improve things by a couple more points. Most of us have probably already done that.

thank you supr cilver for the input. good to know i am not going to be alone in tracking my sc. i want to run streets of willow next spring. do you use 285 front and rear? what wheels and off-sets? i like to run 285-30-18 front and rear

 

I use 285/35/18 in the rear with a 10.5" wheel. I'm currently using 245/40/18with a 8.5" wheel up front, however I didn't like the cornering abilities so I will be upping the front size to 18x9.5 with 265/35/18.

I'm on Tein basics, with 2 degrees of negative camber in the rear. My car got alligned at Dave's Frame and allignment. Our buddy Dale over there does the best allignments in town. All my track cars go there.

I would get Hawk HP Plus pads all the way around too if you are going to track it.

 

I've driven pretty much every Lexus produced and many modded ones. The SC stock is a very good handling car.
