Some details now that pictures have been posted by Laurens. It was hand torqued, checked on every ride for any play and sitting flush on the steering arm. To enable this, i had to machine the hole of the steering arm.
The riser snapped luckily at slow speed and i could brake the car to a halt without additional damage. Bill will for sure check the grade of the metal used for this riser. A straight through bolt of bigger diameter inside a riser of stainless steel would offer i think higher resistance but would require widening the steering arm hole. Additionally, i have an early 2012 car with shorter steering rods, Bill had to manufacture special end rods for my kit.
