Kraftwerks is pleased to introduce the newly redesigned supercharger system for the 2012-2015 Honda Civic Si. Centered around the highly efficient Rotrex C30-94 supercharger, the Kraftwerks 2012-2015 Honda Civic Si kit produces impressive results throughout the entire power band due to its patented traction drive technology. And, unlike any other forced induction system, the Kraftwerks supercharger system provides a linear power curve, torque on demand, cooler operating temperatures, and total driveability. The 2012-2015 Civic Si 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 useable 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.

Nice shoes but run large
Size: 10 Toddler, Color: Pink
Shoes look great but run large. If your kid is barely say a size 10, get a 9. I'm sure my kid will fit nicely in the shoes in due time

Poorly made shoe, not a true size fit
Size: 6 Toddler, Color: White
Too big, or wide around a toddlers foot. I purchased a 5C and my daughter’s foot was so skinny I had to pull the strap tight and she wore sock.

It’s a perfect shoe without the correct width it needed to be wider
Size: 5 Big Kid, Color: Lavendar
The app suggested a 6.5 but I needed it in wide and it was not an option. I had to send them back because they were too tight!
