Turner Motorsport's five years of endurance competition has taught us many things. One was that not all lug-nuts are made the same. While the standard nuts that we sell are great for daily drivers, HPDE events, and club racing, a beefier and more durable nut was needed for the 3-hour, 6-hour, and 24-hour professional endurance races. During the 24 Hours of Daytona, our crew guys made over 80 tire changes in NASCAR-style pitstops. That kind of abuse from air guns and fast work required the "next level" of lug-nut. These nuts are a high-grade steel with a chrome coating and they incorporate several innovative features. The wheel-side of the nut has recessed threads so that the nut has to be square to engage the threads. Without the recess, it's far too easy to start the threads with the nut being crooked. The 19mm head of the nut is slightly rounded to help the socket find its position. The chrome plating that we use is reasonably durable without being excessive. With too much coating, the chipped and worn coating fragments can end up in the threads, leading to all sorts of trouble. Anyone who has used nuts repeatedly knows that the coating is not going to last forever. The constant abuse from air guns will chip it all away. So why add weight and the potential for disaster with excess coating? We did away with most of the danger from that with a lighter coating that still resists the tough environment of the track. Features: Developed for our Grand-Am / Continental race team High grade steel to withstand the extreme abuse of air guns and race conditions Bright chrome plating to help tire changer zoom in on their target quickly and accurately Minimal plating won't result in excess coating wearing off and "gumming up" the threads 19mm hex to prevent rounding off Rounded top for fast socket engagement Recessed threads to aid in fast nut-to-stud alignment without cross threading We recommend using with Turner Motorsport bullet nose dry-lube wheel studs Price is per nut.

Made in the USA The motor mount area on a subframe is one of those easily-forgotton areas that may be hiding a serious problem. The subframe on the E46 has a gusset ('ear') welded on for the motor mounts. These gussets take the stress of the motor mount as the engine torques (more upgrades = more torque = more stress). Worn motor mounts only transfer more stress to the subframe. Unfortunately, the sheetmetal will fatigue over time even though the gusset is reinforced from the factory. Check for cracks along the welds and an uneven plane from the subframe to the gusset. A total failure of the guesset will shift your engine to the side and forward, taking out many other components along the way and leading to a very costly repair.

The next time you replace the motor mounts, oil pan gasket, checking your oil pump nut, or any other time you drop the front subframe, you should install these reinforcements. This kit comes with steel reinforcing plates that are welded to the underside of the guesset as well as plates to close off the bottom of the gusset for extra strength. Instructions included.
