StopTech’s new C60 caliper is the big brother to the existing C43. It features the same brake pad design as the ST60 caliper, while coming in at 3lbs lighter due to its improved engineering allowing for less overall caliper material. Despite being lighter than the ST60 caliper, the C60 is 16% stiffer overall.
The C calipers are initially being targeted for racing applications, but kits are being engineered with small wheel designs in mind (supporting 15-18″ wheels). The long term goal for these super slick calipers is to provide OE upgrades on factory rotors.

KW decided that it wasn’t enough that they had crushed it in all forms of circuit racing, so they went after the circle track market in a big way. KW offers these twin-tube shocks as a pre-configured set of 4 dampers for sprint car applications, or can custom-valve a set based on the customer’s specifications. How did they figure out the sprint car configuration? By taking home wins in World of Outlaws, USAC, and several other sprint car series.
The circle track dampers feature independently adjustable compression and rebound damping. On the rebound side, low-speed damping is adjustable with 18 clicks of adjustment while a second valving stage is preconfigured to handle high-speed work. On the compression side, there is a similar 16 clicks of low-speed damping adjustment for tuning chassis support and tire loading. On the high-speed compression side, a preconfigured “blow off” valve helps to prevent overloading the tire and increasing overall grip.

The folks at Garrett have a new GT55 stainless turbine housing. This monstrous turbine housing has been SFI rated and burst and containment tested, supporting shaft/turbine speeds of over 100,000 RPM. The 1.24 A/R housing has been designed to work with GTX 5533 generation 1 and generation 2 compressors, as well as the GTX 5544 generation 2 compressor. The GT55 features cross bolts preinstalled, which are a safety measure required by many sanctioning bodies. These cross bolts help prevent the turbine wheel from becoming a missile in the case of a shaft or other turbocharger failure.
From a packaging perspective, the GT55 housing includes Integrated threaded mounting bosses for bracing the assembly when installed in a vehicle. As the housing itself weighs approximately 40lb, one can see how simply hanging an entire turbocharger assembly off of a manifold would not be advisable. With a V-band inlet and outlet, this $2350 MSRP housing is available now.

The Wagler all billet DX500 Duramax pattern engine is an astounding piece of engineering work. The clean-sheet design is capable of a mind-bending 3,000HP and 6,000LB-FT of torque while spinning to an incomprehensible 7,000 RPM. And it’s a diesel. The motor is a who’s-who of performance engine manufacturers, featuring a mix of forged internals from Winberg, Wagler, Ross, Competition Cams, Trend Performance, and others.
The DX500 is a “dry” engine. There are no coolant passages anywhere in this bad beast. The block is actually a three-piece modular design, allowing for a top-third that houses individually serviceable cylinders. The head, too, is a Wagler design, providing more than double the flow capacity of a factory Duramax. If you have a need to pull extremely heavy things very fast and for a very short period of time, the DX500 is the answer. Look for an in-depth feature of this motor sometime in the future.
