S13/14 subframe stud dimension.

[S13silvia-200]

Looking to get solid subframe bushes made up. S14 subframe onto s13. need to know what size to drill hole in centre. Got rest of measurements. If anyone has subframe bush to measure. Thanks

They're already in existence? It's probably cheaper to buy the solid bushings ($100 or so) than to CNC your own, just based on materials cost and wear + tear on the mill.

Just a thought.

I think the bolt diameter is 12mm, but I'm not positive, could be 10mm.

it probably would be, but I'm getting these made up for free.

If I'm not mistaken, the s13 requires offset bushings in order to run s14 subframe right? Your best bet woudl he to go down there and measure with a caliper or atleast take off one of the nuts and measure that.
