I have a 2004 MCS with a set of Borbet CA 16's for Winter. Will these fit the new MCS? I've heard rumors of center bore and bolt pattern same, but changed lug bolt diameter changes. Can anyone verify for me? -Pete, Stratmosphere

 

Build dates after July 06 do have the new 14mm lug bolts. You do have a few options though. Assuming that the 14mm lug bolts won't fit your rims you've got 3 options:

1. Buy new rims. Expensive and the there may not be many aftermarket styles available. See Alex at the Tire Rack.

2. Drill out your rims. Since you're not changing the bolt pattern, only the diameter of the exsiting holes this will be fine. This will void any warrenty you may have on the rims. ( I've done this with a local machine shop with out any issues.)

3. Order the conversion stud kit from Texas Speedwerks. I also have this kit now, wasn't availble when I drilled my old rims. This is a great kit and the guys at Texas Speedwerks are really helpful.

Good luck to you,

 

Forum is worth it's weight in gold. I ordered the bolts/nuts just now. We will test them out on the new car. -Pete
