T-Bar Recommendation - .920's?????

Whattya guys think? Should I be running a .920 set in a small block car with sub-frame connectors, KYB's, and XHD's?

Those were recommended, but since I will be running gas-a-just shocks and sub-frame connectors, I figure my squishy .850's are sufficient?

A mainly street driven car with 2.76's would be nice with that sturdy of a bar set, but if I ever went to the track (EXTREMELY HYPOTHETICAL) that extra little flex might be nice.
