What are the 12mm headed bolts for on the front discs of 2006 Z?

[Dragonfire]

Hi guys

Just put 25mm Eibach spacers all round on the Z and came across a 12 mm bolt with a metal sleeve around it on the front discs.

Obviously I couldn't fit the front spacers with these in place so I removed them.

I presume they are locators for the disc but they only screw about 5mm into the disc.

Anyone enlighten me on these ??

Cheers

Mark

Just so you dont put the wider rear wheels on the front by accident

Correct.

Funny, cos I know someone who accidentally had a rear wheel on the front of his 350Z (stock rays).
