[s-cars] Front Subframe Bolt Lengths

[Mike Fitton]

Front position:
M12x1.5x105   N 905 834 01 (qty 2)

Rear position:
M12x1.5x150   N 904 563 02 (qty 2)
M10x40            N 905 677 01 (qty 6)

All bolts but the last are a little difficult to find in bolt stores, so 
the dealer's the easiest place for those.  The last one is a widely 
available size, but the stock bolt uses a 12-pt head that doesn't take 
up much space.  You need this low clearance head to install it.  So 
either get that at the dealer also or get it in socket cap form with a 
washer for each.

The four M12 bolts all go into holes that will deform the ends of the 
bolts to lock them in place, making these bolts one time deals (assuming 
you use a factory subframe mount in the rear position; this is not the 
case with Jason Petek's aluminum mounts).  If you pull them out, you 
really should have new ones to go back in.  At the very least, run an 
M12x1.5 die over their length.  I don't believe the same is true for the 
M10 bolts, but even these bolts from the dealer were relatively cheap, 
so it couldn't hurt.

-Cheers!
Mike
