Z06 vs ZR1 purchase?

Z06 vs ZR1 purchase?
I am hoping to make a purchase in the Fall, and am hoping to get some advice between the two cars. I've driven a Z06 a few times, both on the road, and on track in a student's car at a DE. It had good power, and I enjoyed the handling. I've also driven a ZR1 briefly, and never really got the chance to push it. It felt like it had more power and a more sophisticated ride, but I drove the two cars over a year apart.
I've had in my mind for a long time that I would buy a Z06 one day. I had a C4 ZR1 briefly a long time ago, and really miss that car, so ZR1 has always been in the back of my mind too. I generally prefer the lighter track focused car. I drive a GT3 almost as a daily car, and club race a GT3 based race car. I've watched pretty much all of the youtube reviews on both cars, and the opinions seem to vary widely (I guess that is to be expected). I even found an old Evo issue reviewing the ZR1 and Z06. I think either car would be a lot of fun, and but with the current pricing, either car is a possibility. I plan to drive the car regularly along with the GT3. I won't take it to the track often, but will on occasion, so I want it to be able to hold up in that environment (I've driven 2 C7 Z06's on track, and both overheated on me; not with my student driving though).
Reliability wise, I'm assuming that the ZR1's seem to be pretty well sorted out without any real know drivetrain issues. I'm assuming the same for the Z06 after having the heads redone for about $3k?
These are the pros and cons as I see it from my (limited) experience with both cars. Any advice?
Z06 PROS
-lighter weight
-normally aspirated
-lower cost
-steel rotors
Z06 CONS
-valve guide issue
-stiffer ride
ZR1 PROS
-magnetic shocks
-more power
-body kit
-ceramic rotors performance/no dust
-shorter gear ratios
ZR1 CONS
-heavier weight
-hood plexiglass
-less peaky torque curve than NA
-ceramic rotors cost
Thanks,
David

You can get a Z07 equipped Z06 car that will offer Mag ride and CCB's. Heck, look at 2011 Carbon edition...its essentially a ZR1 with an LS7. Look into the "brick mod" if you plan on pushing a lot of heat through that ZR1 blower on a track. Cheap, but necessary.

If I were in the market for another Vette, I’d wait and see what the C6 ZR1 market starts to do, and then decide. If given the choice, and money wasn’t an issue in my decision, I’d go with the C6 ZR1. On the other hand, the Z06 is becoming very affordable quickly.

I have owned both. Both are fantastic in their own ways. But, now having my ZR1 I would NEVER go back to the Z06. I like the clear lens and the CC rotors will last the life of the car if you do not track it much.
Just my opinion.
And the ZR1 does not have the valve guide issue. Insert eye roll.

Again, the number of incidents means little to me these days...all that matters to me is if my car is affected. If I had a ZR1, I'd at least take a look at what I had going on under the valve covers. As long as people are aware that there could be an issue, that's what I care about these days...what they choose to do with that information is on them.

Zr1. Change the inter cooler bricks and enjoy. It’s an amazing car, great handling, amazingly comfortable and they are very affordable right now.
If you plan on buying one and plan to test drive, bring a dash logic and look at the intake temps, makes sure iat2’s stay low under sprinted driving, if they skyrocket, then the bricks are shot and you should stay away from the car. Spend the extra money on the better overall car, you won’t regret it.

Not looking to debate or convince you of anything...believe what you want, but there have been incidents. Less ZR1's produced, less incidents obviously...but they certainly aren't immune to the same failure. https://www.corvetteforum.com/forums...on-the-cf.html

I would not call this an "issue" with the ZR1. But that is just me.

As for more expensive mods: $1200+ and +porting - snouts, $900 CAIs, Reinforced bricks, $2000 supercharger porting, $2500+ cooling mods, $1000 boost throttle bodies, etc....

Just because you wouldn't call it an issue, doesn't make it a non-issue. I know ZR1 owners that have had valve guides out of spec and know of one that dropped a valve.

more expensive mods but you end up with a faster car with a much more reliable motor that would be way more user friendly while driving.

Google up the Katech report on LS7/9 valve guide issues on this forum. They report same problems with LS9s. Don’t read about them because far fewer produced and of those produced significant number shoved into garages and not driven.

Why is it every single time a ZR1 is mentioned it turns into a pointless pissing match? we all love these cars , but ill take a ZR1 any day over a Z06 it doesn't mean Z06 owners need to be butt hurt over who's car is better!
