We have made a few improvements to our very popular Awesomatix A12 Pancar bumper. We have updated the profile of the bumper to better fit a wider range of 1/12 GTP bodies available on the market today. However, if you prefer the way that the V1 bumper fit on your car, we will be including a 2mm shim to allow the bumper to be spaced up to the same height as the original version. Both the bumper and spacer are made of durable TPU material making them nearly indestructible. Fits A12, A12X, A12WC, Made in the USA
