Faithful readers of Modern Rodding have already seen this Detroit Speed & Engineering built 1965 Buick Riviera in all its Ferrari crimson glory (Modern Rodding Oct. 2023). But many real hot rodders like to take the full tour to see the artwork that lies below. For you see, Jeff Mosings’ Buick Riviera is no showboat, the team at Detroit Speed likes to build cars that can haul-the-mail on the street, road course or autocross circuit. Now since Mosing has ample time wheeling Porsches in the IMSA series, he is well in tune with high-performance machinery for the track and the street. This car was destined to be a perfect blend of unmatched sixties style and ample street performance. Of course, this Buick Riviera is also fully capable of drawing a crowd under the indoor show lights and will blend in perfectly with the other cars at Mosing Motorcars.
After due consideration with Mosing, the final plans were laid. The team at Detroit Speed decided a properly located 9-inch Ford rear end with coilovers out back would be combined with Detroit Speed SLA subframe independent front suspension. There is simply no way to make a personal luxury car this size a lightweight, so that called for some serious brake power. Gone were the big, finned Buick drums replaced by a set of Carbon Ceramic ZR1 Corvette brake pads. Since ultimately the stopping is decided where the rubber meets the road, Michelin Pilot Sports tires measuring 265/35R19 and 295/35R20 will provide ample grip. This combination should handle all the chores, but remember, this car is being built for a man with the motto “Drive Yourself Happy”.
Building the chassis was an interesting blend of old and new. The chassis utilizes the rear kick-up of the 1966 Buick Riviera chassis. This approach provides the stock rear body mounts, gas tank location and room for the nine-inch to move. When this rear portion was all finely blended to the hydro-formed Detroit Speed front chassis you might never suspect there is any Buick metal remaining.
In the end the Buick Riviera had the perfect stance, modern power from a Mast Motorsports LSX 468 LSX engine that is dressed appropriately for the occasion and monster brakes. Thanks to the team effort at Detroit Speed, the end result is one high-performance street chassis that is up for everything from a classy trip out for dinner to a spirited morning drive. Yeah, this thing will drive you happy. MR
