summer performance and autocross tires

Shopping for a set of tires for the '68 Barracuda. I have moved the car from a drag race only to a multi use street-strip-autocross vehicle.
Car info is in this thread
Street Cruser

I currently have a set of 215/60/16R tires on it that are just about used up. I like that tire size for the front, plan to go up a size in the rear.
The wheels are Torq Thrust II
16x7 4.0 back space on the front
16x8 4.89 back space on the rear

I had heard that there is not much selection of true performance tires in a 16 wheel size, that is true. I want to stay with a 26 inch diameter tire and again a bit taller and wider in the rear, I found no tires that tall in a Summer Performance Tire. I did find a High Performance All Season tire in a 215/60/16 for the front and a 225/60/16 for the rear. It is a Sumitomo HTR A/S P03.

Be nice to find something like a Firestone Fire Hawk, but the tallest tire in that series is a 225/50/16 and that is said to measure 24.9 inches tall. I am thinking that would leave the wheel wells looking empty.

So if there is an option for a 26 and 26.5 tall Summer Performance tire out there that I have not found or if someone thinks a less than 25 inch tall tire would look OK, your thoughts are appreciated.
