KSP PERFORMANCE 5X120mm Wheel Spacers, 2PCS 15mm Hubcentric Forged Spacer for E36 E46 E90 E92 E60 318i 323i 325i 328i 330i 335i 525i 545i Thread Pitch M12x1.5 Hub Bore 72.56mm

Got these for the front wheels on my 335i, as well as a set of 20mm for the rears. So far so good; quality seems high and fit/finish are nice as well. My summer wheels are staggered 19s (225/35zr19 front, 255/30zr19 rear) and my winters are matching 18s (245/40zr18) - the addition of these front and rear spacers actually give the smaller 18” wheels a more aggressive stance than the 19” wheels without spacers. Then the 19s with this spacer setup is 12/10. The lug bolts that come with the spacers look nice as well.

Great fit item looks to be of quality

These are great. I’ve had them on the rear of my 2008 bmw 335xi for over a year now.

So far so good. The fitment is so much better now with extra 20 mm. I don't believe there is a lot to say about the product either it holds up and I will never notice it or if it has any problem I will notice it in the future. Again so far so good and also no complaint from my BMW shop that I was quite sure that they were not going to like spacers and even less no top brand spacers. The packaging was careful and correct the bolts were included which was very convenient and every single bolt was wrapped in paper individually so nothing is scratched. I appreciated the quality honestly. Maybe if you compare it to a top brand that cost three times more and you have a very high performance purpose, or if you don't care about the extra money, this might not be for you. But otherwise if you're going to buy the ECS brand or any other middle brand that cost twice this I wouldn't go for it. Save the money.

Get that fitment on point.
