I'll be putting them on tomorrow. I have a question after reading the instructions from tire rack.

Apparently there's a 12mm pin that needs to be removed from the hub before after market wheels can be installed. Is that so? And if so, must it be put back in place when I reinstall the stock wheels in April, or can I leave them out permanently?

 

You can leave it out, its a bolt that sticks into the rotor

Iirc it holds the rotor in place when your taking the wheel off.

 

It doesn't hold the rotor in place. It's so that you can't put the wider stock wheels (for staggered fitment) in the front. Some people have used it to pop out the rotor when doing brake jobs but that's about it.

 

Turns out that with a matched set of stock 19s all around, there was no pin.

As an aside, the winter set are 18s coupled with Michelin X-Ice tires. Holy crap, is the ride different... I mean wildly noticeable. Not remotely close to the summer tires in terms of handling, feeling the road, and ride quality. The winters have given the coupe a real soft luxury feel. Interesting to see how a tire can change the dynamics of the car so thoroughly.

 

I didn't know about it. I am installing winter wheels on my car tomorrow and would have to see
