Wheel bolt sizes and thread types for spacers?
Based on reading various threads on this forum, I think I'm going with 15mm front (3055665SW) and 20mm rear (4055665SW) for my 19 coupe.
27mm + spacer width, I'm thinking I need 45mm bolts (12254501) for the front (42mm, but H&R only has 40mm or 45mm) and 50mm bolts (12255001) for the rear (47mm, but again, H&R has 50mm).
Does this sound right?
Is 12 x 1.25 the correct thread type?
Is tapered (60 degrees) the correct seat type?

Incorrect. The thread is 14x1.5.

For most aftermarket wheels only. For all OEM wheels and some aftermarket replica wheels ball (or round) seat specifically R14 is required.

Not a problem.
With 15mm spacers and OEM wheels, H&R has 43mm bolts (p/n 1454302 or 1454302SW).
With 20mm spacers and OEM wheels, H&R has 47mm bolts (p/n 1454702 or 1454702SW).
