BMW have created a worthy follow up for the Mini. Especially the Cooper S is a fast, small and nimble hatchback. Yet, this client thought that BMW forgot to improve several points. That is why he came to us to give his Mini Cooper S a KCPerformance tuning.
We started by installing a Milltek cat-back exhaust. We also placed a lamda sensor to perform some extra measurements. The engine received a new compressor with a 15% smaller pulley, new Magnecor spark plug cables, MSD ignition coil and colder spark plugs. Hereafter we gave the ECU a KCPerformance chiptune stage 1.
To transfer all this power to the tires, we gave the gearbox new oil, a custom clutch with new pressure plate and thrust bearing, new slave- and master cylinder and we converted it from a double mass flywheel to a single mass flywheel. The tires were replaced by a new set of Bridgestone Potenza's for the summer and Nokian winter tires for the winter.
After further inspection we noticed an oil leak. The head gasket was replaced to solve the leakage. We also replaced the valve cover gasket and the head was skimmed. The engine received new oil and coolant. The oil filter, air filter and fuel filter were replaced by new ones.
Then we checked the cooling. We installed a new radiator in combination with a new water pump and thermostat.The air conditioning was evacuated, we performed a vacuum test and recharged the air conditioning system. We also deodorized and sanitized the air conditioning system.
The suspension also could use some improvements without giving in on comfort. That is why we upgraded the handling. The shock absorbers and springs were removed and replaced by Bilstein B6 shock absorbers and Bilstein B3 springs, the top mounts were also renewed. The trailing arms were replaced by new ones with Whiteline polyurethane inserts. We also gave the Mini new track rods, track rod ends, ball joints and steering rack dust covers. The wheel bearings were replaced and we aligned the wheels. The engine receveid new mounts, these were a combination of BMW and Whiteline rubber.
To stop the car better we gave the brakes an overhaul. We replaced the brake shoes and wheel cylinders. The drums were also milled out and degreased. The brake fluid was renewed and we mounted new Bosch High Carbon brake disks and Ferodo Premier brake pads in all four corners.
The Mini Cooper S drove off with a newer and better version of the Cooper S. A healtyh and powerful engine with a lovely sound, a gearbox that can handle the power with the new transmission parts and put it to the ground through the new tires, a tight and comfortable driving experience thanks to the new suspension upgrades, a cooling system that can perform better then ever, renewed brakes,... Is there something missing to perfect your Mini Cooper S? A KCPerformance tuning pack of course!
