Sorry to hear about your misfortune, my personal suggestion isn't available as an option but that would be to get a set of HRE 595R in gloss black with a polished lip, would look amazing on a yellow spyder.
As far as repairing the wheel, I had my wheels repaired in the past by local places on other cars and they did terrible jobs, but I've also had good experiences. I know a guy in TX if you're willing to ship it out who does a great job. As long as you take it to some place reputable it's a good price, just don't try to skimp on it because when you're going 150mph the last thing you want to know is the wheels you trust your car on were repaired incorrectly.
You have the 02 15 spoke wheels correct?
I might have some used ones in stock, I don't know the condition of all of them since I haven't been to the warehouse in almost 2 months but I'd be more than happy to call and check if you would like.
Also new from us is less than $1,300, we discount OEM Maserati parts 5-15%.
