The word "ricer" is a derogatory term that was initially invented to describe owners of Japanese cars who had modified their vehicle's bodies – and sometimes engines – in a way that appeared amatuer at best and did more to impair performance and looks than enhance it.

So when BMW announced they had a "Power Kit" for the 335i and 135i models I began to worry. Had the sensible Gemans fallen into the trap of adding flashy extras to already superb performance cars only to turn them into the equivalent of a pair of neon-coloured lederhosen?

Sense and sensibility

The BMW engineers are not that guileless. The kits for the two models are a package of engine components, software, and aerodynamic kits to enhance the handling and provide striking design.

The engine kit increases maximum power output on the three-litre, twin turbo straight-six from 225kW to 240kW and torque goes from 400Nm to 430Nm in manual models. Steptronic transmission vehicles get even more pull with 450Nm.

Radiator and air intakes have been modified to cope with the extra heat generated.

An exhaust system, dubbed the "Performance Silencer System" adds dual, chrome-plated tailpipes.

Airflow

Driving around incognito with all that extra power could be enjoyable; keeping other BMW drivers confused as to how and why your 335i or 135i performs so much better. Where's the fun in that?

So after an engine treatment, fit an aerodynamics kit which improves the chassis with lowered suspension and performance coil springs and light alloys. To further reduce weight – and provide beautiful lines - a front apron and integrated kidney grille surround are fitted and carbon fibre makes up the rear spoiler, diffuser and mirror caps.

The cabin gets a racing treatment with bucket seats, racing trim, sports steering wheel and LED displays. An redesigned gearshift, handbrake and aluminium pedals complete the package.

What's it worth?

The BMW Performance Power Kit costs R24 265, excluding labour.

The components are available individually or as an overall package and because the parts are BMW-approved they do not affect warranty and motorplan.
