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. 




Matrix Garage Non Interference piston for up to 8.2mm lift cam


These are made to order so expect 3-5 weeks to get to you.
This is a piston we have designed specifically for mild street builds to stay non interference with cams below 8.2mm max lift. 
We recommend our Matrix Garage 262 cam.
We have now made this available in a number of compression ratios. If you have any question on which you should choose please contact us to discuss your build.
This design is for stock valve diameter but you can request oversized. There will be an additional fee.
When you order please specify diameter.
Stock 81mm
 And specify wrist pin size
early motor 18mm
TRD 19mm
Late motors 20mm
These are designed for Standard size valves. Do not use them with oversized valves.
With the right components this can make a drop in setup. With the right monitoring it can make a pretty high performance setup. We always recommend the best knock monitoring you can justify. 
A great option for mild builds is a knock light.

If you have any questions or want any input on your build please contact us. We are happy to help.
