My car is at JPC now getting BMR springs,panhard,LCA,relocation brackets,JPC UCA,and strange 10 way adjustable shocks on all four corners. I cant report on the mustang suspension but I can say on my 00 WS6 T/A BMR suspension worked flawlessly car ran consistently in the low elevens and went straight every time. I had no noise issues at all. This is why im a repeat customer for my mustang.
Are you getting the JPC Turbo kit too?
