What wheel bolts for MoMo Alloys on Golf

[JCH]

Got some 18" Momo alloys and want to fit them.
I know the standard bolts are M14 x 1.5 with a 28mm thread.
I presume i need the same bolts with 60 degree taper, but just a bit longer.

My cuurent VW bolts (with 28mm thread), are about 6mm shorter if when using the Momo, so i'd guess i need 35mm thread length - would 40mm be too long, or fine?

Thanks
