At what horsepower level should one change the number of lugs for their wheels? I have no idea. Or is it possible to leave it 4 lug, but just go with heavy duty wheel studs and axles.

you can run the four lug if you upgrade the studs and shafts. But going 5 lug will give you a wider wheel choice options... flip a coin. you can't go wrong either way.

5 lug gives you more options for bigger brakes too.

apollo, how much was the rear modified, I mean a 9's car has got to have close to 700 Hp or more. what did you do to the axles, dif, and drive shaft? Does it have 28 or 31 splines?

5 lug swap is 99% for the wheel options BUT there are more 4 lug options than there used to be

the whole 5 lugs is stronger than 4 lugs part is true, but its very unlikely that it will ever become a concern.

It take in excess of 6,000 pounds to shear off an average lug stud. I think you'll be okay.

Yeah, slicks will do that whether you have 4 or 5 studs. ARP makes a stud just for those situations.

I know this car has 5 studs per wheel.

Stock wheel studs, 4,5, 10, whatever, are weak....because 99% of people don't launch the holy hell out of their cars

Thanks, I think apollo made my mind up for me, I am going to stay 4 lug. You can't argue 4 or 5 lugs with a 9 second 4 lug car.
