The Kraftwerks K Series "Race" Kit is built for the hardcore K engine builder.

Centered around the highly efficient Rotrex C30-94 Supercharger, the Kraftwerks Supercharger kit produces impressive results throughout the entire power band. While unlike any other forced induction system, the Kraftwerks supercharger system provides a linear power curve, torque on demand, cooler operating temperatures, and total drivability. The Kraftwerks supercharger system provides instant throttle response and a progressive power curve that increases all the way to redline without the typical 'spiking' or 'surging' associated with turbochargers. This unique, more usable power curve results in reduced cylinder pressures, less strain on engine components, and increased reliability.

Rotrex superchargers also operate much cooler when compared to turbochargers and other supercharger systems, which reduces the engine’s intake air temperature as well as its risk of detonation. Rotrex superchargers are renowned for their compact size, high adiabatic efficiency, low vibration, and quiet operation. Their unique traction drive technology is what makes all of this possible, which, unlike other superchargers, transmits power through frictional forces between its rolling elements. Each Rotrex unit features its own self-contained oiling system that remains independent of the engine. Its dual-action oil pump supplies traction fluid to the supercharger while the supplied cooler ensures proper fluid temperatures at all times.

Kraftwerks has designed the billet aluminum brackets to mount either the C30 or the C38 line of changers. The bracketry is designed to mount the head unit low on the motor in a similar position to that of the OEM A/C compressor. The kit requires the installer to fabricate the supercharger inlet pipe, charge pipes, and intercooler as well as provide all necessary support parts and tuning. Fits K20A, K20A2, K20A3, K20Z1, K20Z3, K24A1, K24A2, K24A4, and K24A8.

Not the best
Size: 7, Color: Black, Size: 7, Color: Black
They are cute but they have a bit of an odd fit that isn’t great for people with narrow feet. They look too dressy to wear with super casual outfits in my opinion. I think the Ugg golden star sandals are much comfier. If you’re wearing these sandals for a really short time they’d be okay. After wearing them around my house for a little while I decided to return them since they started to hurt my feet.

Not for narrow feet, very lightweight.
Size: 7.5, Color: Black
My feet are slightly narrow; these were not adjustable enough to make secure. Otherwise they are cute. The material feels kind of light, these were my first attempt at UGGs so I'm not sure if that's typical or an actual quality issue. Either way, they don't seem very durable but I can't imagine these are meant for roughing it.
