Blackvenom01

i am doing lowering springs shocks and struts and then pump steer on car...do i need to get a bumpsteer for my rear because i saw one on stang mods and i didnt know if i had to do that with the IRS


second can anyone give me a link or some info on tear down and rebuild with this...i have done suspensions on non irs stangs before but never messed with this before....any tips or pointers would be helpful


thanks
