Just installed the S4's....
THIS CAR IS CRAZY!!!
I NEED WIDER TIRES!!!
I did not notice any low end loss, the mid range to top end is unbelievable. The S4's are a bit better than the S3's even with a small turbo GT2871r .64. I can see why sentra guys even install these on the T25's and T28's. I will take the car to the dyno next chance i get, but for now I definitely need some wider tires as I will just sit there in 2nd gear after 3-4krpm's. 3rd pull on the highway was too dangerous on stock tires.
Mind you that this was all on 15 psi. After I get some Azenis 245's in the rear and 225 in the front, I will turn it up to about 19 psi.
