I own the same car.. only modification i had to do .. is grind down the x-member we have connecting from engine to frame on driver side header because it would hit on the x-member

so i got a grinder & grinded it down a lil bit, doesnt really help make our cars as far as tightening up our frame

But I did have some full length subframes installed shortly after & Holy mother of god.. it made a big difference!!

#1 Modification that is a MUUUUST on Convertibles.. get some Maximum Motorsport Full length Subframes welded on
#2 on our slugs would have to be 3.73- 4:30's
