Whats the Difference between 99 cobra rear springs (irs) and 00-02 gt springs besides the spring rate difference, are they made the same??
Impossible. The IRS takes a spring rate far greater than that of a stick axle to function correctly.99cobrasvt said:Because i ordered a set of B+G springs and the guy that i ordered them from said they will fit any mustang even the irs. He said they make one general spring rate for all mustangs. www.b-gsuspension.com the website does not work good.
