Tamiya SRB (Special Racing Buggy) series.
Their early 80's design is famous for its fibre glass chassis with rear torsion bars and front hairpin springs, using lots of metal parts.
The first was the Rough Rider, followed by the Sand Scorcher and Ford Ranger F-150 XLT. The Super Champ was the only Tamiya model to include a feature called F.F.P.D.S. (Free Floating Progressive Dampening System). This consisted of an on board oil bottle to constantly supply oil to a large rear shock absorber, which helped maintain both pressure and lubrication in the shock through hard use. Though adding weight to the car, it worked well, and Tamiya even registered a patent for the system. (www.wikipedia.de)
