Tuscan connecting rods are the best rods available for your European engine due to quality, custom application specific design, and thorough testing. Each Tuscan design is different from any other design because they are custom-crafted and optimized by Integrated Engineering's engineers using the latest CAD and FEA software. This is in contrast to the industry standard which simply resizes standard designs to fit new engines. Each application is vigorously tested in their in-house engine test cell. Integrated Engineering has gone the extra mile to design specific big ends for each application, keeping the bearing in place and reducing chances of failures. This results in a connecting rod that is uniquely strong and light, for the ultimate in performance and reliability.
