after taken the car to the track, with a stock first gen b16. with stock gsr header, short throat shifter, and a dx cluster(no tach) i found my self with a best run of 15.2 @ 93mph. was not to happy with it because i had t ochoose from boging in first or reving and spinning for what felt like ever! so i went on the search and found these. Lightweight ALT263 kappa wheels in gunmetal, 4x100 bolt pattern, 15x6.5" wheels 13.1lbs each w/ 205/50/R15 BF Goodrich G-force drag radials. only taken down the track a few times so the tread is still really good. let me know what think. and how much you think my time will drop.o ya and i payed 250 for them so im happy.
