2 different answers for me and prices will vary.
I had my 3.23 upgraded to 3.73 for $450.00 and it included bearings and gear and pinion seal leak being fixed, so all labor and materials.
The wheels...
American Racing TTIIs I got Discount Tire to go 963.00 for all 4 rims.
Hope that helps a little.

When we dyno test our cars, we put them into 4th gear where ratio is 1:1. When you have different gears the ratio is not 1:1 anymore. It's like testing stock car in 5th gear, which would show a lot less power than you are really making, or dynoing it in 3rd gear which would show a lot more power than you are really making.

Verdad Gallardo umm now you're really losing me. how is it not 1:1 anymore by changing rear gears? no matter what you do to the rear gears, the trans will still be 1:1 in it's respective selection.
auto = 3rd gear
manual = 4th gear
the reason you dyno in the 1:1 gear in the trans is to remove the trans variance
that way crank to trans output is 1:1.

and it's the opposite here also. the lower trans gear will produce less power because it's a higher numerical gearing. just like the gear swap in the rear end.
here's two dynos from my car. same day. 2nd gear and third gear runs. compare blue lines to blue lines. red lines to red lines.
2nd gear runs
3rd gear runs

I guess that I confused the gears, but then don't usually people say that 1st gear is really torquie and the most powerful gear and then as you go up gears car doesn't accelerate as fast and doesn't make as much power? I don't want to argue with you, just trying to get some things clear, and if you could explain it would be great 
Also, I don't understand how the power is lost with different gears. Engine is producing the same amount of power and it's being transfered to the wheels. So, how's changing rear end gears lower the over all amount of power being transfered from the engine to the wheels? Just doesn't make sense to me for some reason. And if we were really to lose that power with gears, how do the cars become quicker at the track?

remember science class where they explained about energy. for instance. you can lift a 1# rock with your hand easily. very little energy produced to move an object. now try to move a 100# rock. it takes more energy to move the object.
now torque is what makes horsepower. it takes less torque to rotate 4.10 gears versus 3.23 gears. less torque calculates to less horsepower.

now there is a point where you can over gear a motor as well. again, we'll use the 10 speed bike method. if you are in 1st gear, you pedal your legs off trying to get speed. lots of effort with little results. now 10th gear, you pedal very little and get lots of speed. little effort with lots of results. it's a fine line getting to the optimum ratio needed to make you quicker without cutting your top end run off.
Gotcha. Makes more sense now. Over all, even by loosing those 10-15whp we still get quicker, it's all that matters
I went to your web site and saw your car and dynos with time slips, how much faster did ya run with 4.10s over your 3.23s?

in my case, in order to not shift into 4th on the bottle, i'll need to shift around 7000 rpms. right now, i'm shifting into 4th about 60-70ft before the traps. and that's at 6500 rpm shift points.
i had more mph in the 1/8 and slightly less in the 1/4 comparing 3.23 to 4.10 gears. seeing these timeslips will help you to see the mechanical advantage of higher numerical gears.
3.23 gears timeslip
60 ft --- 1.842
1/8 ---- 7.599
mph --- 93.58
1/4 --- 11.783
mph -- 117.93
4.10 timeslip
60ft --- 1.709
1/8 ---- 7.500
mph --- 94.05
1/4 --- 11.664
mph -- 117.67
thing to note: this is with a completely stock motor. from TB to cats. if i had a cam that had a range of, say, 3000-7000 instead of idle - 6000, there would be more of a difference.

Do you think it was worth the .1 of a second for the gears? I'm just debating weather I should get them or not. Although, with the H/C it might be a necessity.
I also see that you gained a very decent amount N/A with the gears.
