I like how you frenched the door handles. Very smooth.
mainlandboy, I PMed and emailed you a couple questions, but other folks here who are considering using Miata rear subframes may be curious too, so here they are again:
There are two rows of three bolts holding the Miata rear subframe to the chassis. How far apart are those rows (the right row and the left row) from each other? Also, how far are the forward holes of those rows forward from the axle? And how far are the front hole from the back holes? And while we're at it, how high is the top of the subframe (where it bolts to your chassis) from the bottom of your chassis?
I'm not home right now or I'd measure one myself.
I'm loving your build. Your willingness to start afresh on the chassis was brilliant.
Regards, Jack
Hi Jack, thanks for the compliments.
Of the 6 mounting holes that are on the Miata rear subframe, I only used the front holes and the back holes to bolt it to my frame. I didn't bother using the middle holes on the Miata rear subframe. The left to right distance between the front holes is 31.5". Same with the rear holes. Although I didn't use them, it appears that the left to right distance between the middle holes is 31.1". For reference, these measurements are shown at the bottom of this page:
http://www.miata.net/garage/alignment/I'd have to double check the measurement for how far the forward holes are forward from the axle. The front holes are 14.75" forward from the back holes.
The distance from the bottom face of the chassis frame rails to the bottom face of the kicked up rear rail that the Miata rear subframe mounts against is 11.5". My planned ground clearance to the bottom of the frame rails will be 5" so this puts the top of the Miata rear subframe at 16.5" above the ground.
