"...suggestions on something that might look aggressive?..."
Well, your idea of "aggressive" might be far different from what others think is aggressive.
My idea is the old drag racing look, which would include smaller black wall front tires, and wide white letter rears, all with 15" wheels. I absolutely HATE the modern look of the big wheel/short sidewall tires.
BFG T/A radials are popular. But Cooper Cobra tires are cheaper. Mickey Thompson tires might add a more aggressive look, since lots of drag cars run M/T tires. Something like a P255/60-15 on an 8" wheel might work. Probably best to do some accurate measuring to see which wheel offset/tire size will fit your car. Some here can probably post what works on their car.
Back in '75 I took a '68 off the strip, and put it on the street. I used small tires on the front & wider tires on the rear. If I remember correctly, the wheel brand was Appliance. They made a wheel that looked sorta similar to a Cragar SS. Then, by '78, I switched our bracket Bird over to all Cragar SS wheels. Then everybody started using the solid center Cragar Super Tricks, followed by the similar Center Line solid centers. Those type wheels are still sold. But, in recent years, drag & street cars have used wheels with round holes in 'em, and then many styles of thin spokes.
Since I'm old school, I prefer the old school look. But, I realize it's not for everybody.
Below is a pic of TJ's drag car in '77, with the Appliance spokes I mentioned, on the front, and some old chrome slots I had, on the rear, with all black wall tires. The next pic is that same car & My GTO, with all Cragar SS wheels. The 3rd pic is TJ's street bird, with Appliance spokes, small black front tires, and what I think are wide white letter Pro Trac ? rear tires. Since I can't read the letters, I'm not sure. Would have to look at some other pics from that time period. The last pic is the Pro Trac ad that use to be in all the car mags. I also like the look of the Pontiac Rally 2 wheels. There are several types of that style wheel available today. There are also red line tires.
