I bought a J&M upper control arm mount from a guy and it didn't come with any paperwork.

Which mounting hole is considered the "stock" mounting hole and which one should I use for a car that is lowered 1"?

 

Seriously, nobody can tell me???

 

It is Christmas week.

But I don't know.... you could contact J&M

 

This was something I was wondering as well, hope you get an answer!

 

I don't know the answer but have a suggestion. Put them side by side (OEM and J&M) flat on a table and pass a bolt through the OEM, the hole in the J&M that matches the OEM the closest I would consider the "stock" location.

 

The bottom hole should be the stock setting. But as scott2 said, measure the stock hole on the OEM unit and compare it to the J&M part. But the bottom hole looks like the right position.

 

The way the advertising copy reads, it suggests that the upper hole is in approximately the OE location and the lower one provides for the increase in anti-squat (anti-squat is part of what moving the IC accomplishes).
