These are indeed Computer Numeric Control (CNC) machined to very high accuracy. They go on easily, fit perfectly, centered perfectly. I put them on rear wheels and they've been perfect (but read my update below).Keep in mind, ANY SPACER - especially on front wheels - changes handling and may more or less degrade other aspects in the car's performance (more or less, depending on spacer size/thickness, depending on the overall weight of your wheels and tires, depending on your suspension geometry). Wheel spacers add weight to the wheel/hub, so on the margin they might slow your acceleration a little bit. They increase the weight of your unsprung mass, which will make your suspension a little bit less compliant - i.e. expect slightly less grip on uneven surfaces, in particular cornering. They change the geometry of your steering, but that will vary depending on your car. In my case: I added a 1" thick spacer to my Scion xB1, using +45 offset wheels (thus the wheel spacer reduced the resulting overall offset to +20mm). This made the steering feel a little less quick and responsive, and it made the steering take longer to return to center (i.e. when you "let go" coming out of a corner).For me, the spacer was necessary to fit larger tires. I would not have put them on for just cosmetic reasons, because I liked the steering response better without the spacers. But I'll probably get used to the new slightly "slower" steering response.UPDATE October 2021 (reduced from five to three stars):Prior to this update, I had not driven the front spacers at highway speeds. I put the spacers on to enable fitting larger tires, and first drove around town with them on my old tires, which seemed fine, even with the slight change in steering response. It did not occur to me at that time to try high speeds.After that, I had my shop install new tires and balance the wheels. Upon driving with new tires, I took to the highway, and immediately noticed bad vibration at high speed. I thought - the shop did a bad job of balancing the wheels! But then I thought, I need to make sure the fault is not in the wheel spacers, before I bring it back to the shop. To test for this, I removed the wheel spacers and drove up to highway speeds (and more!) and found no vibration. Then I thought, I'd like to keep the wheel spacers, so what if the fault was in the way the wheels were initially mounted by the shop (they do quick work, use power tools etc.). So to make sure that the fault was not with wheel mounting, I re-installed the wheel spacers and wheels, carefully centering the wheels on their studs and torquing wheel bolts by hand. The vibration returned, although it was reduced. Again I took the wheel spacers off: no vibration at any speed. Just to be certain, I did it all one more time with the same results: with spacers I got vibration, without spacers I had no vibration.I am surprised because the spacers seem very well made and do fit correctly/tight on my wheel spindle, centering perfectly. I've taken them off the front, returned to amazon. (I found another solution for my clearance problem) I've kept the spacers on the rear wheels, where they have worked fine.I like that they are hubcentric, I can access my axle nut through the hole, making replacement of axles a little easier. I installed these on my 1993 Lifted NA Miata. The wheels aren't the best and it doesn't make the tires as rugged as the should appear. I have an 8.5 inch tire on a 6.5 inch stock rim. So the lack of stance aggressive look is not because of the spacers.Shipping was insanely quick, package was received in 3 days almost a week in advance from the expected arrival dateInstallation was simple with the correct bore as well as 1" sizeimproved handling slightly with a 91' Miata with stock daisies, and 14 185/60 bfg sport comp 2 tiresTurning circle has slightly suffered but the visual results as well as handling characteristics have improved out weighing the con.Installed two on the rear of a 2000 miata for daily driver use. Can't speak to the durability, only been driving on them a week. Delivery was on time, parts were correct, instalation was no trouble, fitment was good. Made the rear tires look much better in the fender. 1 inch was perfect for my set up. Wider but still inside stock fenders.I was worried these would be inferior quality because of the great price but those fears were unfounded, the quality was excellent and the spacers installed on my MX5 without any unforeseen issues. The wheels are still in balance with no shaking whatsoever. I would highly recommend these spacers.These spacers are high quality and machined well even though they are very cheaply priced. I put these on my 1990 Mazda Miata in order to move the stock daisy wheels further out and take up the space between the tire and lip of the fender. Worked like a charm and looks much better.Cheapest spacers i've ever bought and they've been nothing but good to me. Fit perfectly as described and have never had an issue after using a pair for 10k plus miles. Good product. Definitely recommendThese seem to be very good quality, quick delivery as well.
