It all started with the passion of John Adrian to create something that other aftermarket parts cannot produce. Most parts he encountered are either of low quality and are made out of inferior materials.
He decided to take matters into his own hands and started designing, testing, and developing parts that would help improve the performance of his vehicle. Using his own car as a personal testbed, he created products that other enthusiasts later noticed, which has become the start of Go Fast Bits.
