They don't have a lot of cushion and don't offer the most support to keep you from sliding around during some seriously spirited driving. Honestly though, they're certainly not horrible…just not the best. I've definitely been more impressed with Mustang seats over the years as compared to the Vettes I've owned.
You've obviously never open tracked a 96 Cobra with stock seats.oke:oke:
I don't find they are all that bad for factory seats. Agree with the cushion part but I'm not buying a Caddy IMO.
I have been comfortable on some decent length rides.
Just my opinion but I don't spend a lot of time in or around them anymore.
I'd rather have a Grand Sport than a Z06. I have more faith in the LS3's durability.
If you're going to mod both of them, and honestly, who isn't going to mod them, the LS7 is a no-brainer. Swap the heads and the durability issue is then a non-issue.
The Grand Sport is a really nice car, but I'd be looking at used Z's over it for sure.
Dropped exhaust valves and thinner cylinder walls on the LS7s. I'd go with an LS3 as well, especially if you plan to mod. I wouldn't trust boost on an LS7 but, that's not to say it hasn't been done. I just wouldn't.
