Racing is brutal! When pushing a vehicle to the razor’s edge, you tend to find the platform’s limitations rather quickly – then set out to overcome them! This is precisely where the CorkSport 3rd<\/sup> & 4th<\/sup> Upgrade Gears<\/a> come in. <\/p>\n\n\n\n

\"<\/a><\/figure>\n\n\n\n

In the years of racing our Touring Car class Mazda 3<\/a>, we found many pitfalls that have been easy to overcome. However, we found the gears’ limit with the 317whp\/355wtq of the CorkSport Turbo Kit<\/a> pumping through the manual transmission. Pair that with a limited-slip differential and wide sticky racing tires\u2026well, it’s shocking the drivetrain has held up as well as it has.<\/p>\n\n\n\n

Destroying a transmission during a race weekend was not a viable path to success, so we developed our own race-quality CorkSport High Strength Gears<\/a> to solve the problem. As you might imagine, this posed some significant challenges. For example, to retain the 6-speed setup, we had to stick with the same gear widths – which are very narrow.<\/p>\n\n\n\n

To gain the strength and durability needed, we opted to use a higher strength material; SAE9310 steel, and to further increase the durability, the surfaces are shot peened. The shot peening process helps durability by reducing the chances for stress cracks to develop, increasing fatigue life and bending strength.<\/p>\n\n\n\n

Since then, we have been running these gears in our TC Racing Car<\/a> for a complete season to validate that there are, in fact, better than OEM. Racing is the ultimate test for performance parts, and we are happy to report the transmission has caught every shift!<\/p>\n\n\n\n

So why might you need these upgrade gears<\/a>?  Do you have a turbo or supercharger kit on your manual Mazda 3 or Mazda 6<\/a>?  Do you like driving your car hard and even doing some structured racing events? If yes, these may be in your future, so you can push your Mazda to the limits without worrying.<\/p>\n\n\n\n

Thanks for tuning in!<\/p>\n\n\n\n
