I considered doing the same, but at this point it just isn’t worth it. Who knows what it would do to the price of a Plaid. I’m not going to remove a $4,500 option to be charged an additional $10,000 on the car.
The Michelin tires on the 21” wheels are over $400 each, so if I was going to add aftermarket 21” wheels I would still need to buy these tires. Subtract the tire price and we are probably paying about $2,900 for the wheels. If I end up hating the arachnids, I can probably sell them on eBay or list them on the forum for about $2,000 - $2,500. So, I don’t think I’m going to lose more than $400 - $900. I can live with that!
