I want to lower my Cobra a bit and am choosing to just add springs rather than go the coilover route. On the MM website, I am very confused as to which Caster Camber plates fit our cars. One selection says Does not Fit 2003-2004 Cobra with OEM Bilstein struts. Use MMCC0304 instead. When I search MMCC0304, it says it fits the Bilstein struts, but then a couple of lines down, it says it does not. Does anyone have experience with using these with stock struts? if not, should I upgrade struts while I am at it? Are the stock struts pretty good? 04 Cobra 30k miles.
