the 993 coolers are difficult to fit in the fender well and air flow is limited. A single front mounted cooler would be fine for a track car. The car is moving so you get constant air flow. With a street car you are faced with sitting in traffic. A fender mounted unit with fan helps keep the temps down in such situations. The dual coolers provides the best of both worlds. It sounds like for the cost of a 935 cooler you could pick up a Elephant Racing Widemounth fender cooler w/fan and B&B/Setrab front mounted unit. What you ultimately end up with depends on the front valance. Are you willing to cut the OEM valance, going with a RS type that allows for a front mounted unit. An alternative is dual fender units.
