well the money is a relative issue meaning that once I decide whish why to go I will focus my money and efforts accordingly. Like everyone else none of this will happen fast, I need to "ease" into it but I am trying to develop a game plan.
I am wondering more about tire width than rim width (unless you are saying 9.5" wide tire).
Is anyone here running 4.10's on the street with a 6 spd? I am thinking it should be ok with 6th on the hwy but don't know for sure.

Regarding the width of the rim, what are you going to use it for? The 9.5" front wheel seems perfect to me unless you are going to road race or something. Otherwise you are just adding more rolling resistance which will only hurt acceleration from a stop.
The gears are not even the slightest issue in a 6-speed/LT4 combo IMO. I have had cars where you sacrifice some things to get the multiplication from a higher numeric rear end, but this car isn't one of them. I couldn't imagine the car WITHOUT a 4.10 rear in it. Even with that, 6th gear is barely lugging along at 75mph. Still good MPG possible, and makes all the gears a lot more fun. Laying down a long 1/2 and 2/3 patch even on 315 Nitto 555R DR's will make them your friend.

I am not disputing the 9.5" wide rim, I am wondering what size tire I should put on it. I am mainly using the car for street driving but I am definitly interested in laying down some rubber. I have no idea what rear gears are in it now but they seem pretty high.

Oops, my fault, I misread that on the tire width. I still run 275's (width) on the front which I think is pretty much standard issue. Not sure what going to a 285 or more on the front would do to handling or if it would cause any issue on the stock backspacing for the front wheel. I'm sure someone who has ran a bigger tire on the stock sized wheel will chime in.

C5's use 245-45-17 up front.....that is what I did...
Depending on your objective, bigger isn't always better

I just went out without my glasses, but I believe that he is right, 285's on the front.

Yup, I got skinnies for straight line fun and 285s for curve carving. Best of both worlds now. Even with 285s up front, I get the same track times as I did with 255s. The Z06 wheels are light enough to negate any extra tire weight.
I was running some 18" 295s out back for a while and didn't have any problems with those either.

Do what you want....
Do what makes you happy! The only thing that is a bit scary on your wish list is the nitrous. Alot of folks have been sorry after blowing engines

I'm skeered of nitrous too, but I haven't needed it so far either. It's not easy getting that power to the ground and eventually something will mess up and eat the motor if preventative maintenance isn't done. If I drove on the hwy a lot, I could see needing more power.

How did you lower it?

Next on my mod list are the 4.10 gears...should have done them sooner but it's a little here...a little there.
