One piece rims
What are they?
The most common type of Alloy Wheel is the one piece rim. These are cast alloy wheels that are made out of one solid piece of metal.
What are the advantages?
With alloy wheels in general there is a significant difference from the standard steel rims but when it comes to the different types of alloy wheels there are no other advantages apart from the style and the look of them. Some may argue that split rims or lightweight alloys are better for racing or track days but that lays in everyone's individual opinion.
What are the disadvantages?
Maintenance on alloy wheels is a lot higher than on the steel wheels. Brake dust has a tendency to eat away on your finish so you will have to clean your rims regularly.
