have 4.10...should I go 4.30?
I currently have 4.10's in my car, Its my daily driver and a 5spd, and i do a decent amount of HW driving.
What would I gain or lose if I went to a 4.30 gear?

I would edit out the whole part out about the races part mentioned. Honestly, you wont see much of a difference going from 4.10s to 4.30s really.

Not worth changing for the amount you'll benefit.

For the DD Mach, I recommend either 3.90 or 4.10s. I've had 4.10s, 4.30s and the current 4.56s since the car is no longer in DD duty. If you hit the track regularly, 4.10 thru 4.56 gears are optimum N/A...

 Not much difference from 10's to 30's, but you will see a difference to 56's. If I did it again, I would have gone to 56's. I turn around 2500-2600 rpm on the interstate at 70mph with 30's. Not much mor to 56's, but a little more low end grunt. People that have the 6 speed trans can easily go with 56's or 88's as the t-56 has a little taller O/D than our 5 speeds do.

Re: have 4.10...should I go 4.30?
4.10's are a great overall gear. Love mine. If I were more of a hard core drag racer with this car than I would have gone 4.56's. DON'T FEAR THE GEAR

Re: have 4.10...should I go 4.30?
I agree with most everyone else in the thread...since the car is a DD stay with the 4.10s. I had them and loved them but since mine is not a DD I stepped up to 4.56s, which are great for an NA Mach on the strip.
Take the money you were going to spend on the 4.10s and put it towards a nitrous kit. With 4.10s, you will definitely see an improvement for your money! LOL!!! LT
