Experience

Before I started racing off-road cars, I was actively professionally racing 1/5 scale on-road cars and I won 2x a European Championship. In my position as R&D Designer at XRAY, I was very happy to be involved again with an on-road project where I could bring my prior experience to the table.

I have thoroughly enjoyed my involvement in this new GT project, and I strongly believe this class will rapidly gain popularity due to its simplicity, easy handling, and great fun. I will continue to support the ongoing development of this new platform, and will be available to support all XRAY customers.
