Since replacing the foam in the driver's seat (bottom + back) my head is noticeably closer to the roof. Seat is all the way down, with a slight lift at the front, and mostly angled back. I removed the jute pad I had installed to gain an extra ~1/4" head clearance, but even still on big enough road bumps my head brushes the ceiling. I'm 6' 3" with a longer torso.

This is an interesting observation, and not something which I had read before purchasing my Z06. I was pretty set on a Z06 vs coupe, though, for some of the reasons mentioned in this thread. (I'm not planning to do a ton of upgrades)

I swapped my 04's headliner for a 2000 FRC headliner. Mine was slightly water damaged, but man I got A LOT of extra headroom from the swap. I'm only 6'1" though.

Based on your profile, you have a 2001, those are the years with more headroom. Headliner was changed in 2003 to reduce head room even more!

Also, anecdotally I did the "side bolster mod" on my old/original seat back foam. At 6' 3" & 200lbs, with a decent amount of muscle, the side bolster mod was too tight. So I swapped in new seat back foam and used pieces of old foam to slightly improve the side bolsters. Good enough for now.

WAY cheaper to start with Z06, there are some upgrades like chassis that you won't be able to upgrade to .. good luck

I did this back when the Z06 came out. I had a 99 coupe and thought I would just mod it up to Z06 level. I went pretty far but I was never satisfied. It was always 'just one more thing". By 2003 I gave up and ended up buying a 2003 Z06. Finally scratched that itch!

when you go to a track event (Auto X for me) it's amazing what a stock Z (with shocks and sway bar,tires) can do against heavily modded other cars !!!!

Depends on the deal you will find. You should also consider a FRC with z51 package!
I found a dirt cheap 99 base c6 with a lq9 6.0 swapped in.
In great stock condition for under 4.5k) So I took some $ and I cam it Ls 6 intake and ls 6 heads longtube and a auto trans stage3 build. I also updated the shocks to c6z06 so this combo will definitely destroy a stock Z06.
so bottom line
A deal is a deal

Portland OR?
Nobody lives there and there are no C5’s.....
Which is a joke BTW. 😊
I’m in Portland.
My coupe has Z06 springs, sway bars, Bilstein sport shocks etc.
I can’t tell you if it handles like a Z06, I’ve Never driven one. It handles better than I know how to drive it.
Stock short block with mods. Runs low 11’s in the 1/4 mile. But it’s an auto, so easier to run good 1/4 mile with.
Fun car. I drive it daily in the summer.
