Here is the third one design we created for Simplex Series called A1-S135. As we already said in the previous post, all our wheels are custom machined in Japan. Each custom forged wheel is born of the special forging, and the quality of forging material is very important. We use a high-grade aerospace 6061-T6 aluminium forgings only. It allows us to offer a powerful warranty - our forged wheels are warranted against structural defect in material as long as the original owner owns the wheels.
