As a side note... While i would love a set of lm tiger wheels the fraser and LM cars ran large flares and reprofiled front arches... 15x7 will work on the rear of a stock car... But probably not on the front.
And if you did try the front of guess it would require a very low profile smaller width tyre which would compromise look and ride... Now if you could do a 15x6 as well.... You can get a much wider market.
