Kato Racing E40Z06

The Kato Racing LS7 project began just like any other e46 M3 that rolled into Castro Motorsport to become a racecar. The factory S54 engine and 6 speed transmission was not enough for the competition Kato aimed for. Once it fell into our hands, the stripdown began; lightening up the car of all excess parts that would not be used on the track. The Cunningham Motorsports custom forged LS7 engine was delivered to the shop. Along with the LS7 swap the power was transferred through a T56 built transmission with a Mantic twin disc clutch, a beefier drive shaft and a 3.15 rear end. As a follow up with a new name, the birth of E40ZO6. Custom metal fender flares were fabricated in order to accommodate the Forgestar 18×11 aluminum finished wheels. They were wrapped around with Hoosier 315/30 all around, making it one of the most aggressive wide body set ups made on a e46. With such beefy tires and massive power the stock brake set up was dumped and upgraded to a much needed Stop Tech 6 Piston Front set up and a rear 4 piston set up. To help the car move along a set of KW Club Sport coilovers were installed to improve track handling.
