As mentioned in my STU build thread on Yokohamas on concrete the Spider has a bit of wheel hop that I would like to get rid of. The car has differential bushing inserts, so further upstream are the motor mounts. It appears the fiat and mazda share the same (lower) motor mount configuration. Reading through a few threads on here it appears the stud may or may not be longer? Either way, there is a not insignificant price difference between the two. Is anyone successfully running aftermarket delrin mazda motor mount on their fiat? Brand?
