Well I got the 4.10s in, and they are amazing. First second and third are useless, and my fuel economy has suffered greatly. I think 3.73s are definitely the more practical choice but I finally get some respectable wheelspin with 4.10s.
If you're not able to spin to 7k or more or have an automatic 4.10's are a bit tall. The best combo I've used was a road race spec tko600 and a set of 3.55's. First was a little long but the more consistent ratio changes made the whole package about perfect for street and track mixed duty.
