Installation was a breeze! Fine-tuning fitment using 3D printing really helped.

The whole system weighs in at 8.5 pounds so ~4 pounds more than an Extreme brace.

If you look at the pictures, you will notice the DIRS was designed so Part 1 (Diff reinforcement) does not need to be removed to drain the differential (plug comes out to a recess and there is a drain track). There is access to the fill plug but it may require a swivel. The main bushing bolt in the pictures is not the final solution. Also, there was not time to have these first five coated and make tomorrow's Legmaker MSHS event; future units will have a hard coating.

Part #2 installed using 10mm P4D self-locking tool-less inserts and APR cross-member bolts:

Cannot test drive today because I am no buddyg and we got 4 inches of snow last night.

I like the gap this leaves to allow the cooling fins along the back remain functional for those of us who may care about that also. Looks good gents. Again, good luck.

Did we ever end up clarifying if this is anticipated to be "stronger" or "better" than the extreme?

Is it a lateral move with a little more "forgiveness" or an upgrade?

Any chance of a discounted group buy when they are ready? After results it would be nice to hear about how they compare to what you currently sell (extreme and standard brace).

Thanks!

Possibly - wanna get some track results and validate the design. Also still waiting for all costs to come in EOQ's.

Looking forward to the results as well. Looks like good insurance and would be cool in colors too.

What metrics are you using to determine performance change from other braces?
