Projects New Front Engine Dragster Build

Hey Guys, looking at buying a bender. I can get a bender for $299 but the bends have a 7" radius. Will that make tight enough bends or should I go with a bender that can get 6" or 5.5" bends? (for twice the price) The bends on this project look great, what radius die was used here?

Thanks

 

IMO, the larger radius bends look "right" on a dragster chassis; and they definitely stress the tubing less than a tighter bend, so I guess you could say that area would be "stronger" with the larger bend.

If you plan on using the bender for a lot of different projects, especially "door" car roll cages; the smaller radius dies will probably be more convenient.
