Tubular top wishbones
Discussion
Tubular wishbones are generally considered to be a potential chassis destroyer. Most accidents involve wheel impacts where it becomes an advantage to have sacrificial wishbones as these deform to absorb the impact without causing damage to the chassis. I don't think TVR manufactured them with this in mind but it is a distinct advantage to avoid damage to the chassis. It's a definite difference between repairable and write-off accident damage

That's where mine came from.As for the strength of the tubular wishbones and the fact that they can damage the chassis.
I would rather have the stronger tubular wishbones and potentially damage the lugs that are welded to the chassis.
The lugs are fairly lightweight and if they were bent or damaged in any way could easily be repaired in situ.
I can't help but feel that the standard wishbones are extremely lightweight not just in weight itself but in their overall strength.
My feelings are that they are fine for road use but when mixed with sticky wider track tyres and far more cornering forces, the tubular wishbones must be a safer bet.
^^^^^^ Can't argue with any of that.
Standard wishbones new and in fine fettle are strong enough but rusty and holes through them they most certainly ain't!
I can't help but think the tubular ones would aide handling a tad, would take vibration over bumps better too, but that's a guess,

This ^^I work in accident repair and see this all day long, you need a weak point somewhere.
These SC Power up-rated folded steel wishbones might be an alternative. Interesting what they say about insurance in the paragraph above the Price List.
