Had a Tanabe overpipe and Perrin steering rack lockdown installed last week, and got the stock primacy's mounted to some Tungsten 6UL's. The slight stretch onto a 17x8 really helps the stock tires out. They still don't have great grip, but they're better than I thought they were when I 1st got the car.
I would've preferred the Perrin Overpipe, but the Tanabe was ~$150 shipped. Haven't noticed any added NVH from the Perrin lockdown so far.
