Umi Boxed SFCs

I was wondering if anyone was running these SFC on their LT1 car? If so how are they working out? I was thinking about buying a pair off of WS6store for fairly cheap.

I like tubular since they fit better and sit closer to the body.

I always thought the tubular ones were a little more flexible than boxed.

Round tubing is stronger against torsional and angular forces, but square tubing is more resistant to parallel forces from side to side. In a SFC application where strength is the point (you're tying the subframes together, so this should be obvious), boxed is a better choice. If weight is more important, then go with tubular SFCs.

I went with boxed. No compromises in rigidity.

How big of a weight difference are we talking? Can't be more than 20lbs, right?

10 lbs of weight is worth the added rigidity, IMO.

Thanks for the input guys. I was going to change my order to tubular, but was unable to. I have the boxed SFCs coming tomorrow. Either way its better than doing nothing. Does anyone have drive shaft input/suggestions for the new 9" thats going in? What yoke should I use?
