It would be fine and the gears dont add any HP

Sure why not
No HP gains but sure does feel like it[sm=burnout.gif]

the 4.10s may equal the FEEL of pehaps 40 hp in first, 30 in second through fifth. In other words, they are worth it.

As far as having any harm in motor/trans., I wouldn't think so, but I'm not sure.

dont fear the gear, go 4:56

Gears don't add no hp, but they sure feel like you gained atleast 30 extra ponies. I just got the 3.73s and It feels likethe car justpulls so much harder.

4.10 no lower. You'll kick yourself in the ass if you go lower than 4.10.
