The 20mm TMS wheels spacers include extended lugstuds for the correct amount of threads needed to safely hold the wheel on.
Turner Motorsport is the first American BMW tuner to put engineering principles into wheel spacer design. They have set the bar for fitment, lightness, practicality, and longevity. These wheel spacers feature quick release pockets which enable them to be removed quickly and easily (instead of being frozen to the hub like poorly designed spacers), are made from high grade aluminum with military-spec hardcoat (which is far stronger than standard anodized metal) and are CNC machined to precision standards to ensure no vibrations and optimize weight without affecting strength.
On the scales, the 20mm front wheel spacers come in at a light 1lb 3.25oz.
After spending a lot of time comparing the wet and dry performance of many different tires online, we decided to stick with the Continental ExtremeContact DW tire. We have been very happy with the performance of this tire over the course of tens of thousands of miles on both Project E90 M3 as well as Project E36 M3 (Silver). This tire is hard to beat for a performance-oriented daily driver.
Continental Tire is heavily involved in North American endurance racing by supplying tires for the IMSA Tudor & CTSCC Championships. Here’s the Turner Motorsport BMW M3 GTD car that I have driven to many podiums over the years.
