90mm Extension (70mm bolt pattern)

I needed a small extension for my VRS base to attach an OSW wheel. Aluminum ones were over $100. I decided to remix a quick connect into an extension and see how well it held. I Had a longer version of 120mm but it broke. I shortened the extension to 90mm and did a 50% in-fill and it has been fine for about a month now. I run at 10nm, with my primary racing being endurance racing, so stress test has been pretty lengthy.

I did have to drill out the holes slightly so the bolts would easily slide through. You could also thread them throw, if you want.

Enjoy the savings and print your own.
