perfpackages

Welcome to GTT’s proven range of performance packages & Servicing for the Gen 1 Mini Cooper S.

Proven for over 10 years now. The GTT 220 for example we have now fitted over 600 of these. This is undoubtedly the best selling and long term proven aftermarket conversion in the UK.

Not only will you find spec that is higher than our competitors (e.g. Iridium Spark Plugs, Idler Pulley & New Drive Belt included at all levels), but prices that are unchanged since 2005. Each package is based on achieving a combination of maximum power, drivability & reliability, with maximum value for money.

If your car already has non GTT performance parts fitted that you wish to add to, we can produce a custom package for you, so no need to feel left out! The testing and developing of the GTT conversions includes many thousands of road miles, hundreds of track miles, drag racing & rolling road sessions.

We have stripped the engines, gearboxes & most other parts of these cars down to the last nut & bolt. Only then, in our opinion, should license be given to sell & fit tuning parts to these cars. Of course we did have a head start, which is 25 years in motorsport, competing, designing & manufacturing parts, and 25 years involvement with aerospace, Formula 1 and Indy Car parts manufacture.

Notes: Power figures are typical. Please note we have used only fully independent rolling roads to establish output power during development of these conversions. Actual power output is very dependent on temperature, humidity, and engine/supercharger condition. Unfortunately it is also a sad fact in the motor trade, there are those that occasionally will fudge results on their own dyno to make their conversions read high & likewise, competitor’s conversions read low. For these reasons we only use fully independent ‘non Mini specialist’ rolling road houses. Some items within these conversions are ‘exchange’ e.g. cylinder head & throttle body. Technical info & pictures of the components of each package can be found in the ‘Performance Parts’ section.
