Metric High Tensile Caliper Bolts

[Gts-t]

I've put 33 brembos on my 32 gtst, the front bolts that come with the front brembos are too long and need a fairly big spacers (lots of washers etc) which I'm not keen on using. The nissan bolts have a 9 on the head which I believe is a JIS standard. Not sae and not metric.

I went to the local bolt shop yesterday and got the right length metric high tensile bolt grade 8.8. It was the highest they had. From trawling the net for awhile I am thinking I really need at least a 10.9 or possibly a 12.9 grade instead.

Anyone have any thoughts or experience with this?

Thanks

Yes, 8.8 not enough. IIRC 10.9 is the minimum grade.

By the way....have you thought about going to a brake shop, like a Midas or ABS Brakes, to obtain said bolts? You just know that they will have some, don't you?

Thanks gtsboy, I will try abs it's just up the road we do deal with them but it hadn't crossed my mind tbh. I may also try Coventry fasteners etc if I have no luck with abs. I hadn't done my research and it was a quick Friday arvo thing and the 8.8's were only about $4 lol so I grabbed them anyway. Was hoping to get the install finished tomrrow. Rears went on no problem.

Also which Midas are u talking about not the shonky service centers?

Should put ur name in ur info too.

Yeah, even shonky Midas places (which are not all shonky by the by) will have new bolts in stock because they deal with brakes all the time (there was time when Midas were exclusively a brake shop) and will have to use new ones when servicing some brakes.
