Rear Wheel Power Increases - The Spin Zone
Weld makes ultra-light three-piece wheels in varying strengths, from drag spec to road-race spec. When buying, be sure to use an appropriate strength of wheel. | 
This one-piece Weld wheel is built to SAE street specs, which makes it strong and light enough for track day events. |  |
