I read this before and if it's still true I'd take it in consideration:
"For street applications, I think that they (summit wheels) would be great, but for drag racing applications, I don't think that they have the strength in the taper seat design. The only thing supporting the wheel to the axle stud is the small conical seat area. The Weld or mag wheel design that uses a lug nut with the washer and shank design on the nut spreads out the load to the longer shank area of the 5 nuts. Big difference. Even though Summit lists them in the race wheel section, I'm not so sure that it should be considered a race wheel but more of a street wheel with the race wheel appearance"
