IIRC it is ET23 front and ET 11 rear

 

The SRT-4 is a nice tuner street car, but not very high on the list for a track car. They ran with us in Grand-Am Cup before the factory abandoned them and they were in the faster group on the straights, and in the slower group around corners. There is a difference between a track car and a race car though, if the competition had similar power, the SRT-4s wouldn't have stood out.

You can make a decent track car out of anything, but there are so many far better choices its hard to see why the SRT-4 would even be up for consideration.
