My car is 3/4in lower than what it was, I know, and I am sure that the bullit suspension is not the same as the mach1 suspension, as one lower it .5in and the other one is 3/4in, I cant remember what was different, I knew at the time but I dont remember now. You can search for both parts #, they should be different as a company in toronto was advertising bullit springs and shocks for sale as well as mach1 springs and shocks for two different prices.
