These are 44-tooth rings. The stock rings have 48 teeth, so these rings will change your displayed speed by a factor of 44/48 = 0.91, or about 9%.
If your speedometer is reading about 9% too high, these rings are for you.
(If you speedometer reads only 6-7% high, then you will need 45-tooth rings).
Made of a magnetic stainless steel, polished for best appearance to a mirror finish (it is hard to photograph a mirror, pictures do not do them justice!), they are also a perfect aesthetic upgrade to the stock black painted rings.
The ABS/MSC and traction control will still work, and not fault codes will be set.
