KSP 5X120mm Wheel Spacers, 2PCS 12mm Hubcentric Forged Tuning Spacer for E36 E46 E90 E92 E60 318i 323i 325i 328i 330i 335i 525i 545i Hub Bore 72.56mm Without Lug Bolts

Cheap alternative for spacers, I used these on a road course and have done 3 Track days on them with no issues. So build quality is good.

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.

Super good for the price. No issues

I recently snagged some wheels for my E60 that I mistakenly thought were the correct offset. I am not typically a fan of running spacers, but I really liked the wheels, so it was time to look around at some that would do the trick. It was suggested to go 25mm rear and 20mm front, I opted for 20/15mm instead. Having read a ton of the reviews and seeing issues others had with the inferior spacers, I went with these are they're forged/machined aluminum that are anodized, not the typical pot metal cast aluminum ones or stamped steel.Slapped em on, drove around and not a single bit of vibration, shake or shimmy. The car drives as smooth as it had without them on the previous wheel set. It's very important to note, you DON'T use an impact on them. It says clearly hand tighten at 70-80 foot pounds of torque. I would guess many who have issues either have a tire shop slap em on and they use impacts or they themselves do as well thinking it won't matter. It might not, but then again, they leave these instructions for a reason.The packaging was nice as everything including each lug bolt were individually wrapped to protect from any knicks or scratches. These are well worth the money and they do exactly what they were purchased to do.

Good quality material

Went from 18” to 19” wheels on my 2008 528i noticed there was grinding on the inside rim. Just needed about half inch to clear bought these installed easy fixed my issue. No vibration or anything in steering wheel. Makes car look more aggressive.

Good stuff. Perfect fit and good quality.

Great quality, easy to put on, makes wheel fitment look how it should've been. (2007 bmw 328i)
