I have an 02 z06 that I will be doing several de's with. I have done about 10 so far and have at least 8-10 I should make this year. I do drive my car to work in nice weather. I want to use harnesses this year. I would also like to be able to use my stock belts for driving to work. sparco roadsters are attractive because they allow pass throughs for harnesses which the stock seats do not but I can use my stock belts as well because the thigh bolster is lower. However I can only use a 4 point belt since there are no sub holes I beleive. The evo2 is attractive because I can use a 6 point belt but I dont think I can use a stock belt and it would be harder to get in and out during daily use due to the thigh bolsters. what do you think?
