Your link is no good.
I'm highly interested in seeing some pics
For sale is a new old stock set of custom Speedline Alessio 3 piece wheels in chrome finish originally made for an Audi A4. These wheels are as new absolutely mint with zero flaws to speak of and this only adds to they uniqueness of this offering. They are 18x8.5 with an offset of et36 and 5x112 lug pattern. They have a large hub bore so can be used on any vehicle with the correct hub ring. All original and never used with all markings, hardware, etc. in tact. I have been sitting on these as they are one of my all time favorite wheels and this is a one of one set not to be seen again. These are the same wheels that were factory for the 911 3.6 turbo and certain Ferrari applications in the mid 90s which sell for 2x my asking price. These are one of the most beautiful wheels ever made and look even better in person. If you have any further questions please let me know and I will answer to the best of my knowledge.
I would prefer a straight sale of $2500.00 but would entertain trades involving other 18" or 19" wheels of the BBS, HRE, CCW variety. Serious parties feel free to contact me @ 760-390-0067.

Not too sure about spare parts but anything can be repaired or made if necessary. These are brand new so no need to worry about condition. You could always get wider barrels made from any wheel maker if you really wanted. 8.5 to 9 really isnt worth the effort in my opinion however but you may feel differently.
