With a 20 inch wheel on this car, you would need a 255/35-20 tire size for a proper fit.
Yes the'll fit but they'll definitely rub.

Since nobody answered this I will take a stab at it... To fit 26" rims and tires on my 96 impala SS you will need 275/25/26 inch tires... The old problem we have with tucking big wheels on 94-96 impala's is the rear tire moving to close to the front of the rear wheel well... But they make rear extenders for that to center the wheel back there... But some people managed to pull it off without
Yes. But there are some important things to remember. Tire size, wheel back spacing make a difference.
265/75/r15
is a 96 impala faster than a 93 corvette
1991-96 Buick Roadmaster, 1991-96 Chevy Caprice/Impala SS, possibly 1993-96 Cadillac Fleetwood
Since they're basically the same platform, it should fit without much problem.
No, the 94-96 Impala did NOT come from the factory with a sunroof option. However, there are many Impala's out there that had sunroofs installed by the dealership that they came from when they were new. So, it is possible to find a 94-96 Impala SS with a sunroof.
There are no points on a 96.
