Over the last couple years the priorities in my life have changed. Had Matrix Garage grown big enough to hire enough employees and leave them to running it while I pursued other things I would have happily taken that route but it has generally stayed just big enough to keep me working overtime. 
I have decided to start focusing my carreer and passions elsewhere and that means that supporting the AW, AE, 4A and related communities has had to be moved much lower on the priority list. I have decided to keep the store up to provide parts that only we offer, or other things that are hard to come by elsewhere. You will notice many big name, readily available products have been taken down and we will continue to do so. It's just not worth our time trying to compete with the big corporations selling at cutthroat prices and it just takes up more of my time. 
I will try to keep providing those parts that we make or that we have developed and sell as a service to the community but understand that now this is something I do in my spare time because I don't want to leave people hanging. 
I try to make shipments and process orders at least twice a week. If you want Amazon next day shipping buy from Amazon. I will do my best to keep order time and customer service at a reasonable level but have some understanding. I am not making money on this and it takes away from my other work and other issues that are very important to me right now. 
I have always wanted to make our designs and other information open source and available to the community but to do so properly would take a lot of time making sure that models and drawings were complete, accurate, or properly described. To go through everything and make sure it was something that I felt comfortable releasing to the community. I would love to find someone who was willing to help me do this. Someone in engineering school or passionate about this to help go through 3D scans, CAD designs, and information to prepare it. If you are interested feel free to email me. 




Inner axle bolt E51 AW11 supercharged, E153 SW20 turbo


Titanium Grade 5 axle bolts with safety wire holes. 
The most common reason for axle bolt failure is some or all of the bolts coming loose enough to where acceleration torque applies shear force directly to the bolts. When properly torqued it should be nearly impossible for the bolts to break. 
We have had these bolts made with safety wire holes to add one more level of security to keep the bolts from coming loose. If done properly this is one of the best ways to secure bolts and ensure they don't come loose. 

We also recommend a small dab of loctite as well. Doing both together should ensure these bolts will not come loose until you are ready to remove them. 
Price is for one set or side. If you want them for both axles order two sets.
