[edit] LP400S
In 1978, a new LP400S model was introduced. Though the engine was slightly upgraded from the LP400 model, the most radical changes were in the exterior, where the tires were replaced with much wider Pirelli P7 units, and fiberglass wheel arch extensions were added, giving the car the fundamental look it kept until the end of its production run. An optional V-shaped spoiler was available over the rear deck, which, while improving high-speed stability, reduced the top speed by at least 10 MPH. Most owners ordered the wing. The handling of the LP400S was improved by the wider tires which made the car more stable in cornering. Aesthetically, some prefer the slick lines of the original while others prefer the more aggressive lines of the later models, beginning with the LP400S. The standard emblems ("Lamborghini" and "Countach") were kept at the rear, but an angular "S" emblem was added after the "Countach" on the right side.
There are three distinct Countach LP400S Series.
Series One — The first 50 cars delivered with Campagnolo "Bravo" wheels in 1978 & 79. The very early 1978 cars had the original LP400 steering wheel. Small Stewart Warner gauges, 45mm carburettors and a lowered suspension (lowbody) setting is a trademark feature of this celebrated first series. Halfway through 1979's production, bigger gauges were employed. 50 cars were built and the last one is noted to be 1121100*
