Our ProSTIX string alignment tools attach to Pro and ProPLUS HUBStands, directly in line with the center of the hub. Each ProSTIX includes measurement scales that are adjustable for your specific wheel sizes. 
The mm indexed scales allow you to easily read each wheel’s Front edge-to-R edge difference and see the exact Toe Measurement at all four corners at the same time. The ProSTIX eliminate the need to walk back and forth, around the car using hand measurement scales under the string line, or even easier with HUBStands LASERStrings. ProSTIX come as a set of 4 and are adjustable for wheel sizes from 13″ to 20″.
They work with traditional string kits but HUBStands LASERStrings were engineered specifically to work with ProSTIX.
HUBStands are made in the USA, in an AS9100 facility (aerospace certified); precision machined from 6061 aluminum and available to fit almost any race car, from GTLM’s to open wheel racers. They come complete as a set of four with stainless Toe Sticks and a choices of interchangeable multi-pattern Hub Plates.
