hey spike
 

whats a good DR size for a stock mustang 15" wheel?

the stock like v6 15x7 wheels?

I would rock these 275's:http://store.summitracing.com/partde...5&autoview=sku

Or if you are worried about running them on that size rim (lots of people do it) you can run 255's: http://store.summitracing.com/partde...5&autoview=sku

cool thanks!

I use the 275's on stock 94 15x7 v6 wheels by the way :)
