All coupes (except M3) use the same springs, regardless of whether or not it has Sports Package. These are the same springs used on Sports Package sedans, which do use different springs for non-Sports Package cars. As long as you're buying springs/shocks made for non-M3 coupes, it will fit just fine. 2.
this is different in the M3 compared to 330Ci: front and rear bumper, sideskirts, front and rear fenders are wider, hood has different lines and has a power bulge, quad exhaust, trunk lip, side grills with M3 logo, wider stance in the rear, wheels, mirrors, always black window trim, black headlight trim + black portion between the headlights to complete the headlight "black-out" look.
Thomas Plucinsky, BMW Product and Technology Communications Manager told us all BMW engines are designed to run on 91 octane. All performance testing, including EPA emissions and fuel mileage, is done with 91 octane. However, though BMW is all about performance, their motors will run on 89 or 87 octane without damage.As with the E46 M3 itʼs resale value has remained high. Whereas there were M3 sedans in the E36 and E90 body styles, the ZHP sedan was the closest you could get to a four door M3 in the E46 line
