One Japan’s oldest tuning firms, HKS, just can’t stop fiddling with the Mitsubishi Lancer Evo X.With more than a quarter century of tuning and performance refining experience, HKS, the brainchild of former Yamaha engineer Hiroyuki Hasegawa, has an enviable reputation in the high-performance and street racing industry.As a Japanese brand, HKS likes upping the ante on locally produced models. In true tuning style the names they give their aftermarket cars are ridiculous. Witness the latest HKS, the CZ200S Mitsubishi Lancer Evo X, successor to the outgoing HKS CT230R Circuit Time Attack Evo.Conventional engine dimensions, unconventional powerA car not designed for aesthetic appeal – the front splitter, intake ducts and rear wing are hardly an ode to good taste – CZ200S is simply bolted together to go really, really fast.Featuring a revised turbo kit and larger injectors (1000cc) boost has been recalibrated to run in perfect harmony with the reprofiled camshafts. Considering the forces it produces, strengthened internals (forged pistons and H-beam con-rods) were called for.The net result is CZ200S producing 428kW and 657Nm from an 2l in-line four. Which we are sure you’ll agree, is quite a lot, considering this remains essentially a four-door Japanese C-segment sedan.Mitsubishi’s redoubtable all-wheel drive system has been upgraded with an HKS twin-clutch set-up and experimental six-speed gearbox.Try and see your mates keep a straight face when you tell them about your Hipermax suspension or Endless Racing brakes. Nobody will be laughing at the end of timed track session though...Comic relief component names, dead serious performanceOddly named, but undoubtedly effective, Hipermax III suspension keeps the CZ200S mostly on track, whilst the Endless Racing (we kid you not) branded brakes upgrade the standard Evo X system with six-pot callipers up front and quad callipers at the rear.Grip is provided by Yokohama’s finest rubber, Advan Neova AD08s. Onboard the CZ200S is a host of boost adjusting and lap timing equipment and of course Takata seatbelts – which is obviously something each and every Evo X owner longs for. Thanks to the those relatively unmolested front and rear light clusters, with their indicators intact, you can drive to CZ200S on the morning school run to drop off the kids, even if you work in Sandton and they go to school to Bloemfontein…Best to stick to trackwork though, which is the reason HKS conceived the CZ200S.On a recent shakedown run, with the Yokohama rubber, it clocked the vicious 14-corner, 2km Tsubuka circuit in 59.5 seconds. In perspective? Currently the Nissan GT-R does a Tsubuka hot lap in 1.01 second...For the record, Tsubuka's all-time original chassis record holder is an all carbon-fibre HKS CT230R, which blitzed the track in an expletive generating 53.6 seconds.
