Spinner thread identification can be confusing since Left Hand Thread spinners are located on the Right side of the car and Right Hand Threads are on the Left side of the car. So if you see an LH or RH that could mean Left hand side of the car, or Left hand thread for the Right side of the car. So after the final buff and micro polish, we take the time and go the extra mile to hand etch each of our Forged Alloy spinners with the LHT or RHT thread direction on the back of the spinner for unmistakable identification.

We are just finishing up a big batch of our legendary Spinner Eaze Anti-Seize and included a new, helpful addition to our label. Our Spinner Eaze can replace any other anti-seize using very little product, lasts far longer and without the mess. While we have tips and hints on our webpage they won't all fit on the label, so we added a handy QR code to the can so you will always have directions, tips and hints no matter where you are. https://performanceunlimited.com/cobravalley_chemicals/spinnereaze.html

Just completed two very special custom "thin air" carbs for two Cobras, one for 3,500 feet and the other for 10,000 feet. Along with clean high altitude operation, owners will enjoy snappy throttle response, increase power, more torque, smooth drivability, maximum fuel economy and easy starting in all weather, and even at those higher altitudes, of course!

Every batch of Spinner 911 tools we put out always has an improvement added to them, whether it being design, fit, finish, strength or even the instruction package. This month's batch has several improvements increasing strength as well as including these little details which may seem minor, but it was worthy adding to make using the tool just a little easier and more efficient to use. There is no attention to detail that is too small to take the time to improve upon.

Two more Stainless Steel *Cool Fule* gas tank fuel return adapters completed and ready to go out the door to concert a standard fuel tank into a full flow return line for both fuel injection and carburetors in just a few minutes! While they may 'look' simple on the outside, there is a lot of science, research and decades of field experience on the inside.
