I am happy to report that there's no longer a need to move the stock outboard balance weights when installing MGP Caliper covers. It turns out that when Artsci worked with MPG Calipers to design the Volt covers, the company never had a Volt to test on - they assumed that it was identical to the Cruze. This is why there's a need to move the wheel weights.
Anyway, I called MGP to order covers and the experience was awesome from start to finish! The office manager, Crystal, was super helpful as was Ben, Director of Sales & Marketing; they arranged to have my covers installed for free because I'm local in San Diego. Today, I had my covers put on by Oscar who immediately realized the problem and called Mike who seems to be in charge though I don't know his position. Oscar and Mike fixed my covers on the spot to make them work without moving the wheel weights. They also made a change to the specs on the template for the Volt caliper covers so that the wheel weights will no longer be a problem for anyone with stock 17" wheels. Photos here:
My covers: The Black thunderbolt was decided on by Crystal. I chose the red Volt letters on yellow powder coat.
Here is Mike modifying my covers to make them fit
Oscar trying it on for size:
Finally, Oscar modifies the template Volt Caliper Covers so that they fit without problems. Here's the template on my volt:
The guys also took photos of my installation to put on their website. Anyway, MGP is a great group of folks who do some really cool work and are real car guys! Here is the finished installation:
