I don't believe their are controls arms by themselves. Kenny Brown sells a kit to replace the bushinged stock subframe for a hardmount unit and comes with new control arms with "improved geometry". But honestly, the claimed weight savings and geometric changes aren't worth the expense or the changeover especially when you read through Bruce's experiences with the unit. This IRS is awesome, and this bushing kit is what reveals its true potential. Everyone claims the Cobra IRS is SO heavy and says it sucks...The new Camaro's IRS weighs 390-lbs. Noooo spank you.
Great review and pics OP!
10-4,., thanks for the info and sorry about the highjack.,., :-D
