I am thinking to add the TCP strut rods to my 1970 Mustang. I have the upper and lowers TCP arms and spring perches with ball bearings. TCP claims there strut rods help with alignment and increase caster adjustments. My car is being built from ground up and I am now starting on the suspension. Are these rods worth the money? Are the stock rods as good as the TCP's with rubber bushings? Thanks.
