Curious what specific wheel sizing and/ or offsets I should specify when ordering new wheels for my ITS car. Have run with the wheels that came on my car for years, but they weigh about 20 lbs each. Will probably buy a set of 15x7 Kosei's, but my mind is open, mainly want to be sure to order the right spec's.(If it makes a difference, most of my races are sprints @ VIR & Summit Point).

Any help/ advise would be appreciated !
