The body kit had flared arches at the front and rear and a new aluminium rear spoiler replaced the IV FRP version and gave an adjustable angle of attack to alter rear down force. The track was widened by 10 mm (0.4 in), the wheel offset changed from ET45 to ET38 along with the wheel diameter which rose from 16" to 17" to accommodate Brembo brakes which were added to enhance braking. In addition th
e brake master cylinder bore increased by 0.3 millimetres (0.01 in). The engine was strengthened in a few areas and the cam duration was increased. The pistons were lighter with a smaller skirt area. 510 cc injectors were replaced with 560 cc injectors for better engine reliability due to more electrical "headroom" and the ECU was changed to include a flash ROM, allowing more boost pressure to the same TD05-HR as the Mitsubishi Evolution III and IV. Furthermore, the turbocharger was again improved. Torque was increased to 373 N·m (275 lb·ft) at 3000 rpm. Power officially stayed the same, at 280 PS (206 kW; 276 hp), though some claim horsepower was actually somewhat higher. Evolution VI - The Evolution VI's changes mainly focused on cooling and engine durability. It received a larger intercooler, larger oil cooler, and new pistons, along with a titanium-aluminide turbine wheel for the RS model, which was a first in a production car. The Evolution VI received new bodywork yet again, with the most easily noticeable change being within the front bumper where the huge fog lights were reduced in size and moved to the corners for better airflow. A new model was added to the GSR and RS lineup; known as the RS2, it was an RS with a few of the GSR's options. Another limited-edition RS was known as the RS Sprint, an RS tuned by Ralliart in the UK to be lighter and more powerful with 330 hp (246 kW). Yet another special edition Evolution VI was released in 1999: the Tommi Mäkinen Edition, named after Finnish rally driver Tommi Mäkinen that had won Mitsubishi four WRC drivers championships. It featured a different front bumper, Red/Black Recaro seats (with embossed T. Mäkinen logo), 17" Enkei white wheels, a leather Momo steering wheel and shift knob, a titanium turbine that spooled up more quickly, front upper strut brace, lowered ride height (with tarmac stages in mind), and a quicker steering ratio. Amongst other colours, the Evo VI came in either red (Tommi Mäkinen Edition only), white, blue, black or silver with optional special decals, replicating Tommi Mäkinen's rally car's colour scheme. This car is also sometimes referred to as an Evolution 6½, Evolution 6.5, or TME for short.
