Hello, if you don't already know I am biased as we are the imported of them. But i'll add some info.
The Rigid Collars have now been verified for over 2000 applications. Each kit is verified and tested individually, nothing is left to guess work. Here is the Japanese blog showing the new vitrification and news

We have never had a set returned. We have never had a refund requested. We have never received negative product feedback.
I have personally dropped the sub frame on the front of my DC2 no less than 5 times and reused the same collars - they are not single use.
The collars are very different in design to the likes of SW Motorsports of Tegiwa, their kits are are not a comparable. During the development process, this type of early collar was tested and developed and mostly resulted in failure!
The development story:
Back in 2006 during the development of the Spoon Sports Acura RL it became apparent there was difficulty in maintaining correct alignment of the sub frame to the chassis. Due to a difference in materials welding of chassis and sub frame was not and the idea of a Rigid Collar was convened.
To objective is to integrate the body with the sub frame with a material the offers strength and durability, whist not causing damage to the adjoining surfaces. As a result of repeated testing of many different aluminium, alloys and tempered materials the most suitable material was chosen
With the correct material chosen different designs were chosen and then tested on the vehicle. To allow the collar to correctly align the holes in the chassis with the bolt it is necessary for the collar to be tapered. Each collar is specific for the application and has its own design. Once the collar is installed the chassis and sub frame are as one; like monocoque chassis
The next stage of development was testing of the Rigid Collars under the most extreme of environments – endurance racing on the circuit. Differed designs, taper angles and surface finishes were tested. As you can see from the image below the design and material plays a very important parts in the durability of the collars. Material too hard and you damage the integral chassis and sub frames and too soft and the collar will damage as visible in the picture below
The final prototype is has is finished and installed to its specific vehicle for further road testing
The Rigid Collars are difficult little things to difficult little things to justify but certainly add to the overall enjoyment of driving to any car.
