Turbosmart’s latest Kompact valve kit has been developed as a direct plug-and-play solution for the new C63 AMG.

Despite its high-performance intentions, the Mercedes’ standard bypass valves are plastic units that bleed boost and struggle to cope with the pressure, particularly in tuned vehicles. 

Turbosmart’s Kompact kit for the C63 comes with two billet aluminium valves that are a direct fit replacement for the factory diverter valves.

The Kompact holds boost in better than the factory valves, and can never be overcome by boost. The result is more efficient performance from the factory turbochargers, as well as the crisp sound of a piston-style BOV.

For those who want blow-off valve sound, the Dual Port both vents-to-atmosphere as well as recirculates air, while the Plumb Back is 100% recirculating for quiet, OEM-style operation. 

Unlike the factory valves, the Turbosmart replacement kit is mechanically controlled by manifold pressure, meaning the valves open when you want them to, not when a computer decides they should.

This puts control back in the hands of the driver, and ensures the valves do not release boost when they shouldn’t.

Turbosmart's new Kompact Shortie Blow-Off Valve for the Mk7 takes performance to the next level. These valves are a high performance replacement for the Golf's standard diverter valve. Unlike the standard valve's plastic construction, they are machined from aircraft grade aluminium, and bolt straight up to the factory location, offering all the technology from Turbosmart's race-bred BOV range in an OEM-replacement package. The Plumb Back is a 100% recirculating blow-off valve, routing all vented air back into the intake. This valve operates at a similar level of volume to the standard valve, avoiding unwanted attention. Turbosmart's Kompact Shortie does not leak, bleed boost pressure or struggle with increased boost on tuned vehicles. It also completely eliminates compressor surge, allowing the Golf's turbo to operate to its full potential, and for longer.

• Plug and play compatability
• 400% stronger than the OE Diverter Valve
• Designed to handle boost pressure up to 30PSI
• Ideal for lightly modified vehicles

H&R springs 28826-1 for Audi A3 incl. Lim./ Sedan + Sportback Quattro

H&R sport springs 28826-1 for Audi are the ideal solution for the enthusiast who appreciates race-bred components designed for street use. Suspension is one of the most important factors in determining your vehicle’s day-to-day drivability. The first step in suspension tuning is to upgrade your vehicle’s stock springs. Upgrading your suspension components will ensure that your vehicle has improved handling and reduced body roll. H&R springs have superb ride comfort and increased driving convenience. 

All H&R springs are made from high-strength spring steel to ensure first-class quality and performance. The springs are designed in such a way that they can be easily combined with standard or retrofit dampers and offer a sporty look. A powder coating also improves corrosion resistance while giving the spring a high-quality appearance.

Product benefits:

• Sporty appearance
• Improved handling characteristics
• Lowered center of gravity
• Linear or progressive spring design
• Compatible with OE and aftermarket shock absorbers
• Powder coated for anhanced appearance and corrosion resistance
• Delivered with ABE or TUV approval
• Engineered, manufactured and tested in Germany

The secret to such success? To put it simply, the technology H&R employs to develop cutting-edge suspension systems for competition use is the very same used to develop innovative suspension components for street-driven cars. In addition, H&R maintains extensive involvement in several touring car, GT and Monoposto racing series. Not to mention the Formula 1- where each circuit may have its own demanding characteristics. 

In the harsh environs of competition, H&R is able to test new materials and innovate production technologies. All of which can help racing teams adapt to changing road conditions accurately and efficiently.
