[84GT350-1]

Whats the best sub frame connectors on the market these days. If I install sub frame connectors can I run mid 12's with out the added strength of a roll cage. I hate a cage in a street car but don't want to twist up my sweet 89 coupe. Will be dropping in a 350H.P. 351w with a 5 speed mainly for the street but may see some 1/4 mile. Thanks for the help....
