My friend has this kit on his.

He is running faster in the 1/8th with this on stock tires and 7 PSI than he was in his SR S13 Coupe w/ better tires and 12 PSI by about .5 seconds, its running on par with his stock AP2 S2K. He has also had a first gen Gen Coupe, which was god awful in every category.
I personally like the car's looks, it is a bit under powered, but with the aftermarket support you can fix that, and the thing handles really well.
