That Factory Five roadster used ifs and it looks pretty good, but the whole car is built like a race car, so I guess it Ain't "Traditional" lol. But I was familiar with their cars, before the roadster, and they handle like a race car. I like the I-Beam on a fenderless Hot Rod. But then thats me. Now some with the S-10 factory a frames, and no fenders......... Well they cover that stuff for a reason.
