Thoughts on C7 Z06 and C7 Grand Sport from previous Supra owners?

Does anyone have any direct experience with them? I'm considering moving on from my 6pd Single Supra which makes ~530whp. I know I can hit up corvette forums directly and do plenty of online research, but I'm curious of what previous supra owners thoughts are.

Worked on and modified about a dozen of them. They're fantastic cars with basic bolt-ons. Bone stock they're ~525-550whp and an overdrive ATI crank pulley, intake, longtubes, and a tune regularly gets the car in the ~700+whp range on pump. Power is instantaneous and sounds great. Tons of support and a massive aftermarket that's rapidly pushing them to very crazy levels. At 700whp it's basically 'bpu' and can be driven almost everywhere reliably. At the limit they don't just go batshit suddenly like a C6Z or worse the C5's. The interiors are vastly nicer than previous vettes. The autos are surprisingly not shitty, but I still prefer the manual. Avoid the carbon brakes, IMHO - they don't really make that much of a difference in 99% of braking situations and the replacement cost is disgustingly expensive. If you end up with a car on carbon brakes, replace them immediately with iron rotors and good pads to match and just put the carbon stuff in a box to either sell and make a lot back, or save for reselling the car. Everyone that I've seen replace the carbon brakes with iron rotors and regretted it just bought shitty McPads. Carbotech XP10 and XP12 pads for the C7 are fantastic and match very well though they're dusty - but I can clean some brake dust when I wash the car in trade for a brake job that doesn't crest $4k per rotor like the carbon rotors.

C7's overall are much better put together than C5's and C6's, too. They're excellent cars. But as fast as they are and as nice and new as they are, they just don't feel as special as a Supra and while they command some street cred, it's nothing like the Supra's.

If you wanted another ~200whp on pump with instant response and wanted it to blend into traffic better, it's an outstanding option. Personally, I'd augment a Supra with one, I wouldn't replace a Supra with one.

Agreed. As is common with Jeff's posts. :bigthumb:

Fantastic response.
My good friend has a beautiful 2014 C7 that he is going to be supercharging soon. Going for 750wheelhp.
He is trying to convince me to get into one.
I'll be honest... it is very tempting... along with a used GTR (early 09 etc model).

But I'm too loyal to Supra and am going to wait and be patient for the right one to come along.
Then maybe race him someday... and show him who is still the king of the streets.

I’ve had my C7Z06 for about 3yrs now....

Pros:
Very daily drivable, reliable and comfortable
Good mileage if you behave
Magnetic ride control is a dream
Lots of cool tech
Power all over the place

Cons:
Can’t hook for shyt with the stock rubber unless you really warm up the tires
Lots of them around

In short, is it a replacement for a MKIV.. NO. But then again I don’t think anything is a replacement for a MKIV Supra hence I bought all these cars and never sold my Supra.

I have a friend with a C7 Z06. Very nice car and feels faster than it's published 1/4 mile times.
As far as modifying, the Z06 is good for another 60-70rwhp with your basic pulley/tune/exhaust, after that is gets more expensive thanks to the tiny supercharger and lack of fueling with direct injection. The one good thing if you're planning for big hp is that the Z06 has a very strong engine with people pushing over 1K rwhp on stock internals-that's usually done with one of the Procharger F series blowers.

As for the Grand Sport and LT1 engine, the pistons are the weak point with there tight ring gap. When supercharged, most tuners keep them under 650rwhp unless you do a piston swap.

My gf's parents live next door to a guy who is really into corvettes. He has 6-7 of them including a c7 z06, an early 90s zr1, and the rest are all old classics. When he bought the c7 z06 my gf bought his c6 that he was going to trade in. I got to drive it quite a bit. They are nice cars, fun to drive, low to the ground. I could see myself owning one someday. I feel like you draw more attention in a Supra though. That and I don't think Corvettes will hold their value as well.

Something else to consider is the value of a Supra vs a newer sports car like a C7Z. The value of the Supra's will continue to go up while something like a C7Z will decrease in value.




^Is that 3KGT in your sig an actual 1999 VR4?
