PROMOTIVE 5x114.3 Wheel Spacers 12mm - 5 Lug CNC Machined Forged 5x4.5 Hub Centric Spacers Compatible for Infiniti G37 M35 Q50 & Nissan 350Z 300ZX - M12x1.25 Studs, 66.1mm Hub Bore 2PCS

These are by far the most durable and well protected wheel spacers I have used. Very confident they will survive the harsh winters here

These are really high quality feeling. Worked perfect for my application

Excellent Quality & Perfect Fit

they look good didn’t get to install because my studs aren’t long enough i’m sure they’re good

Good quality, perfect fit. Just what I needed. Highly recommend

These are great for my G37 flush should have went like 5cm bigger

Decent set. Used 20 and 25 mm for my cx5 and so far so good, 15 mm wont work without trimming, due to hub studs being too long.. i love that u cant see them because they are black.. love it.. steering is now a bit harder but the rear stays in the corner nice being 7 inches of the floor...can feel the bumps a bit more due to moving wheels outwards but not the suspension but if u own a mazda u get used to it.. i hope they last, will be checking studs every 6 months..

These are heavier than most so they will hold up. Improves stance on my G37 when using smaller tires in the rear. Wheel rubbing can be a problem so make sure you have at least and inch of space on the offset before installing them or they will rub in the rear.

Perfect
