I've read from a few people that there is no speedo gear for 4.56 gears? So for those who run them, how do you compensate for the errors in the speedo? Do you run an aftermarket one, or is there no way to make up for it?

Also, are the 4.56s too high for what will soon become my toy car. I'm gonna get a DD and I want something completely wicked to play with every weekend on my mustang. I think that these would do it, but are they too much for what I'm running right now? Would 4.30s be a better choice overall?

Thanks.

It is hard to choose gears when I don't really know anything about your combo. How high does it spin? What size tires are you going to run. What is your transmission ratio? Got any dyno graphs? Is this used for 1/8 or 1/4 mile?

Depends on your combo and stuff like Mackey said. And what rpm you need to cross the traps at. I just switched from 373's to 430's as the 373's were killing my combo and I was crossing the traps 1000 rpm's too soon.
