Need advice for my 5.0

I need better traction for my 93 T-bird 5.0 I have Futura2000's 215/60/15's on there now, I need something, at least in the rear *slightly larger for that mean look, and hopefully some traction gain*

I am going to keep my rim size, and adventually lower the car, I need better traction for when I launch.

Size, and brands?

The 215/60-15 is not the correct size for your T-Bird ... it is shorter than the recomended size of 215/70-15. A 225 tire width will fit your car with no problem. So, check out what is available in 225/60-15. We currently have the AVS Intermediate from Yokohama for $47.00 each plus shipping
