It isn't just these two bolts mentioned in this thread. It is ALL the bolts.
This is another example of why a Life and Death Nut and Bolt Check is critical before taking any car built by any company out on track. The more track miles you put on you Z, the more critical the Life and Death Check is.
Short Answer -- Get your Z on a lift. Replace those two bolts with full shoulder bolts. Use LocTite. Use a vibration proof fastener like this.
Torque it down and periodically check it.
Or just send your Z to me  |
Pete >> Thanks!
A quick google images search made me realize that we need to know the exact size (diameter) and the size of the shoulder as well.
Why don't you specify the exact (correct) bolt and washer to use....as in give us a supplier and url to exactly the correct sizes to use?
Your experience will help us get the right one on first. I'm sure I'm not the only one who would appreciate this.
I prefer a grade 8 bolt..which is what I'm assuming these are, as the bolt head isn't visible to see if theres an 8 on it.
Or tell us the correct size bolt from a place like MSC:

EDIT:Your picture says
www.heico-lock.co.uk as its address; so just specify which washer you use for us??

Oi?? RED locktite not blue?? You must be planning to never get it apart again. I'm going to use Locktite Blue on mine (once I know the EXACT shoulder bolt and heico washer, so if something
ever loosens I can get a new bolt in there.
