are there any aftermarket wheels that don't require them? when i had my e46 m3 i never had to install wheel spacers. i'd like to run 245/40/19 front and 275/35/19 on the back, so what should be the proper wheel size and its offset? also will wheel spacers cause excessive damage on my stock suspension in the long run(like 3 years)? because my car is leased, will the dealer noticed anything weird on the suspension even after i put the oem wheels back on when i turn in the car? thanks guys.

 

There are a ton of wheels out there that don't necessitate a spacer. What style of wheel are you looking for?

 

my choices are down to 19in racinghart c4 and the dpe r16 with black center and polished lip,

 

you wont need wheel spacers as long as you have the proper offset. if you have brembos you'll need a lower offset to clear them, otherwise up to +35 should still fit but will look tucked. you're looking for something between 20-25 if you want an aggressive, flush look with the fender. browse around the wheel threads and see for yourself how different offsets look. there shouldn't be much sign of wear from running spacers but i've heard my share of horror stories about them.

p.s. you are probably referring to hubcentric rings. some aftermarket wheels do not come with them and they are are not necessary, but help keep the wheel solidly mounted on the hub and more stable at higher speeds.
