Looking at the H&R 17mm spacers, they need extended length bolts.

Could someone let me know the specs which would be needed? A fool proof link would be great...

I've seen the standard bolts are m14x1.5 22mm for the GranTurismo.

Remove one of your bolts, measure the distance from the end to the taper, add 17mm and then buy bolts with the spec you had above.

I tried and I failed. They are too tight for my tool.

New tool has been ordered, but if anyone can assist in the meantime that would be great.

I am getting 50mm from bottom of taper.

Don’t H&R spacers come with bolts? Mine did (22 mm & 25 mm)

The spacers thinner than 22mm use extended bolts, the thicker ones bolt onto the hub.

Looks like H&R 70mm (extended) bolts are £13 each. Obviously quality is key but that seems a bit steep...

One of the several reasons I won’t do spacers is the length of the bolts. If you buy from a reputable seller, you are probably also contributing to their PL insurance premium.

The bolts on mine are a match to the OEM bolts. I would only use hub centric spacers myself.
