I spent a fair amount of time looking for a high-quality quick release for my steering wheel and my search came to an abrupt end when I found the Krontec QR-03. It’s a radical departure from the spline-based designs that dominate the market. It has the following advantages:
It’s impossible to misalign the steering wheel
Zero play
No splines to wear
Smooth and easy spring-loaded action
Positive indication of when it’s locked
Optional 22-pin motorsport connector
I bought it a couple of years ago and now that I have machined the steering wheel boss it’s time to get it mounted. I drilled a 6-hole, M5 x 70 mm hole pattern in the boss, but I couldn’t mount it directly to the quick release because I need space for wiring. To accommodate this requirement, I purchased a spacer from Krontec and I machined a mounting plate from 1/4” aluminum. The mounting plate serves two purposes; it relocates the mounting holes so that they don’t get too close to the OEM holes in the steering boss and, when combined with the spacer, it provides the proper amount of room for the wiring.
From upper left to lower right; quick release, spacer, flat head screws, steering boss, mounting plate, socket head cap screws, washers and nylocs
Six flat head screws affix the mounting plate to the spacer and steering-wheel side of the quick release and six socket head cap screws affix the mounting plate to the steering boss. The flat head screws can’t back out because they’re retained by the steering boss. I had to cut all 12 screws to get the perfect length, but that’s how these things go.
While the stack looks tall the overall height is about an inch taller than the steering boss was before I modified it. This will help me fit a modified OEM steering wheel.
