If your car is driven on the street alot then i would go for the wider front wheel (atleast a 15x6) if it's a track only car i'd say go for the skinnies.
Please post pics when you get these wheels mounted. I am going between these and the holeshot wheels (polaris or sunflare). The welds only offer 3.5 or 4.5 bs that would work for the regal, which kinda puts the tire too far to outside or too far to inside. The holeshots come in 3 7/8 bs which would be a better fit on a 15x8 wheel. If 275/60/15 dr are used then it's still close to frame on my car. May have to use a 1/4" spacer to clear the frame.
