Just installed the eibach pro kit and now i got low speed noise coming from the rear springs..i don't think the stock rubber isolators can handle the stiffer spring pressures. I've been all over the net can't seem to locate any....please let me know. i prefer urethane over rubber...i found them for the 99-04 mustang but none for the 05-2010 mustang...

 

yeah i know they don't exist...

 

Assuming the axles haven't changed then the Energy Suspension 9.6106 polyurethane isolators should fit the bottom of the springs (these fit the 07-09 GT500 8.8" axle).
