I recently put the RX 7 conv BBS rims on my 929 and a few things are worring me

1 - there seems to be a gap between the hub and the rim, its about 1/4 of a inch. The stud doesnt come all the way flush with the lug nut, it sits about 1/4 of a inch in. When I drive everything is fine, no alignment problems or shaking steering wheel, even at 75mph

2 - I lost a center cap on my first run, that pissed me off really bad, I tighten the cap really good by hand (I dont have the wrench) but wasnt sure if it clicked or not. How can I make sure the cap will stay on ??? how much is it to replace the center cap ???

the rims are 6.5 inches wide, will 225/55/15 tires fit ???

 

The FC wheels are not hubcentric for your 929. I recommend you remove the FC wheels from your 929. They were not for that car.

 

I figured it wasnt safe so I removed them today. Is there any RX 7 rims that would fit my 929 ???

how much do you think I could sell my rims for ??? there mint ??
