Here is what you can expect from the options listed:

Using the smallest axle diameter allowable (based on HP) you will encourage both left & right axles to “wrap-up” at virtually the same rate. Maximizing axle wrap will make it more difficult for the tire to break traction on acceleration, whether it’s on corner exit or on restarts. You don’t have to worry about the axle breaking from twisting, the material & design is meant to twist all day without any damaging effect on the axle.

Best Suited Track Type: Dry-Slick

This option is our maximum recommended offset between the left & right side axle diameters to allow for “on throttle” turn like that of adding tire stagger. The greater the diameter split between the left & right axles, the more “loose” the effect is “on throttle”. Forward bite is slightly reduced to a degree (from Option #1), but the axle diameters here still remain much thinner than standard axles sold which will allow for axle “wrap-up” and increased forward bite over any standard diameter axles.

Best Suited Track Type: Heavy or tacky

Here we utilize axle diameters that will provide a bit of both Options #1 & #2 (Forward Bite & Throttle Turn), using smaller diameters overall with a slight split between left & right side axle diameters. This options best captures a bit of axle wrap (Forward Bite) with the thinner overall axle diameters & throttle turn (the tire stagger effect) that comes with different left-to-right axle diameters. It is our most commonly used axle combination.

Best Suited Track Type: Starts heavy or tacky and gets more dry-slick through the night
