OK, dropped my centers at the powder coater today, should be back Thursday, $180 for the 4.
I put a torque wrench on the bolts when I took them off and basically there was 5lbs or so torque to loosen them. I never thought to try and tighten them, sorry. I will go with 10 or 12lbs when I do them up.
First wheel took me a while until I realized that the bolts were ever so slightly stuck in the hole so only needed to hit them from behind with the wrench to loosen them, then hit them with a drill and extension/socket to unwind them. No need for the hex-head to hold the bolt tight from the front.
I had the rims face down on a towel, with another towel folded over a few times wedged under the face to prevent it dropping when I hit the last nut.
Nero, did you paint the lip that the face bolts to? Not sure what that will look like when bolted up, i.e. anthracite face mounted to the polished lip?
Does anyone know what part of the wheel is forged, and what is cast? That face is pretty heavy....
I bolted on my 18/19 LE37s (nice spares to have around, right?) and the car feels quite a bit faster....the LEs ARE pretty light though.
18/19 LE37s 38.1/47.5
17/18 GTCs 43.0/50.1
16/17 stock 36/1/42.7
Nero, I don;t think I will need your spare bolts at this point - forgot to reply to your offer, sorry about that,
