We are sending new silicone block plugs at no charge to all of our customers who have purchased the R35 jack pad tool. http://www.ReverseLogic.us
The first jack pad tools offered by Reverse Logic Limited were for Mercedes-Benz cars. The MB jack points have one notch in either end of the vehicle jack pocket in the jack points. The Reverse Logic jack pad tools for MB cars have spring loaded pins that snap into the vehicle jack pocket notches and hold the tool in place while a floor jack is maneuvered into place.
BMW jack points also have vehicle jack pockets. But the ends of the pockets have smooth walls without notches. So a completely different approach was needed to suspend the jack pad tool from a BMW jack point. We chose to use industry standard rubber caps which look like small rubber "bullets". The bullets are about 1/2-inch long and 1/4-inch in diameter. They protrude about a 1/8-inch from the end of the jack pad tool block. When the jack pad tool is pressed into the jack point, the bullets are compressed and create enough friction to hold the jack pad tool in place. This solution works ..... most of the time, provided that you carefully follow the instructions for inserting the tool into the jack point. Basically, you insert one end of the tool first compressing the bullets against the wall of the pocket and then swing the other end of the tool into place, and then release the pressure on the first end.
The GT-R jack points are similar to the BMW jack points in that they also have a smooth-walled vehicle jack pocket. Initially the jack pad tool for the GT-R used the same type rubber bullets that we used in the BMW jack pad tool. Feedback from our customers indicated that some folks were having difficulties getting the jack pad tools to stay in place while they were positioning the floor jack. Our customers really did not want to hear us tell them to RTFM (Read the Fine Manual).
So, we set out to come up with a revised tool that is intuitive to use. We also wanted something that would allow us to offer an upgrade for the tools in the field. We have retired the industry standard rubber bullets in favor of silicone plugs that we had made specifically for our tools. The new plugs have a collar that increase the contact surface area between the plug and the pocket wall. The new plugs also do not protrude as far from the end of the jack pad tool block. The result is that the tool is easier to insert into the jack point and that it holds in place a lot better. So much better, that we are sending a set of the new silicone plugs to all of our customers who have purchased the R35 jack pad tools for their GT-Rs. Almost more importantly, you can ignore the instructions and still be successful.
