Ridetech Coilover Bracket

[Josh@Ridetech]

The dimension you are looking for is just under 0.70", however there is a "flat spot" machined into the upper ring mount (which can be seen in the images above), so we typically use a mount that is 1.185" to ensure plenty of clearance.
You can go lower than this, but make sure nothing hits when the shock moves (like the adjuster knob).

I misunderstood, I'm sorry!

There's the info you need, thanks Britt!
