Geez,

I must be a wimp. I went to Bilstiens and 1.06" T-bars on my 1973 Charger and I think it is about as stiff now as I'd want it. It feels GREAT on the road but going over train tracks makes you get whiplash. I think if I had gone much stiffer, I'd be unhappy.

I guess it's just me. However, I'd take the 1.06" bars I have now over the crap .92" that were on there before!
