Nice looking truck, the wheels fit well.
I would lose the TB spacer but it doesn't really matter. I think you should be in the 14's with what you have. My excab was 15 flat with similar mods on a hot summer day.

You'll hit 14's with ease. I only suggest one thing....run a set of stock 16's at the track. Don't get me wrong, those Torq Thrusts look absolutely awesome on your truck. I just think 16's will allow your truck to run its full potential.

yah i know I should run soem 17's(mcgauthy drop spindles are 17" and up), but then Id be running it down the track at something that it isnt like on the street...u know what I mean...plus I dont have other wheels...lol...I gotta buy some cheapy 17's somewhere..I know the 20's are a performance killer tho....Im interested in what I'll hit with the new mods....Jsut gotta hoook it up...

thought about slicks...but I dont want to grenade the rear...so well see

I know this sounds dumb too...but the TB spacer is there for MPG....lol...my dads 04 CC went from 16.1MPG to 19.8 mpg after a tb spacer...they make a considerable difference on the 5.3

I would say most likely 14's with the setup. Obviously you could get better number with some long tube headers and such. Just a question though, as far as your tune? Are you still using the stock 99 PCM or have you upgraded to an 02 unit yet? If still using the 99, your probably leaving a lot of power on the table.

Yah I ahve heard alot about thye 99-00 pcms having false knock issues..but Im pretty sure that with a great tune, with someone who knows what they are doing, you dont need to go switching pcms.

I know this is a back anf forth questions, but with a solid tune I think Id be good to go..
