This site is so great.....I hope you guys can help me out here? I have a 92" SC400 and I'm about to purchase some 19x8 (f) and 19x10 (r). What offsets should I get and what tires would match. Someone told me that I needed a 42 offset for the 19x8 and a 40 offset for the 19x10. Is this true. I don't want the wheels/tires to stick out but be flush with the fenders with a little drop. How much drop would you suggest? Thanks alot!!!
