Ferrari 308 GTS/358RR

Model: 1981 Ferrari 308 GTSi

Project Overview:  This 308 GTSi was converted into a 358RR at the request of a Denver, CO customer. In addition to the larger 3.5-liter Razzo Rosso engine the customer had us upgrade the chassis for improved performance as well. Handling was greatly improved thanks to an adjustable coilover suspension, particularly when paired with the larger 17x8-inch front and 17x8-inch rear Compomotive alloys. The brakes were also upgraded with larger Girodisc rotors at the front and high performance Wilwood calipers at all four corners.

Engine Specs:

251 lb-ft of torque @5000-rpm, 280.29-hp @6500-rpm
