I've recently decided to run ap1 rears on the front of my s2k and I found a machine shop to bore them out for me. All I need to do is give them the size I need the wheels bored to, so I thought I'd double check my findings on teh internetz with you guys to make sure. So is the oem front center bore 70.7mm? Thanks!

 

70.1

99% sure of that.

 

Okay thanks! Got another member that said that too so I'll tell the shop to bore the wheels to 70.1mm

 

No prob! Tell them to go to 70.2 if you have rusty hubs

 

Ehh if I remember correctly one of the hubs is pretty rusty and the other is not so bad. Should I just do 70.2 for both wheels? Will that extra mm be enough to cause any noise?

I was mostly goofing around. The extra .1MM won't cause any problems if you properly tighten the lug nuts.

You should probably use a wire brush to be rid of any surface rust you can get off.

 

this was a big pain for me!!!
