If they're for mostly drag racing look for a different wheel. Those are heavy and will have too little sidewall. Not to mention your tire choices are going to be limited.

 

so would telestars or somethink like that be better what size backspacing. ive seen most are running 15x8 with 5.5 bs or 15x10 with 5.5 bs. in the class i run i can have up 10.5 wide slicks or 13.5 wide street tires. i have 4.10 gears and 26 x 8.5 et drag right now looking to going to 28x 10.5 soon.

 

If you're allowed to run drag tires and skinnies in your class then go for it. Where I race, the street class is only allowed DOT tires and front wheels must be full width, no skinnies.

You need to calculate what tire height will put you through the traps at your desired RPM. For example I knew I wanted to trap around 5400 RPM based on my dyno results so with a 4.10 gear in third with 5% converter slippage that put me at 28" tall tire.
