MX5 Rear shocks

[Stot]

So I ordered the wrong rear shocks and springs for my build and Im working out what shocks to order to replace.

It looks like NTS were supplying 12" x 8" but im going with standard GAZ sizes which come out at 11" x 8" or 12" x 8.5".

With a rear ride height of 5.5" the shock will be sitting at 9.6".

The 11" give a 2.4" droop and 2.3" bump at the wheel.
The 12" give a 4" droop and 1.6" bump at the wheel.

So, 12" or 11"?

Cheers

Did some more digging. The suggestion on bump vs droop is 50%-75% bump so the 11" look like the better solution for me. Cant go down to the 10" as that would leave me very little droop.
