i did 165 in the ms3. i had coilovers, but still wouldn't call it comfortable, lol. I hit 120 pretty often and it was pretty comfortable at that speed really.

I like that little tuner cabo thing. But I wouldn't expect to fiddle around with the car too much if it's my DD and I still have the miata.

only thing that sucks is you have to reflash it to make any changes, which takes a few minutes, car has to be off, etc.
