I lowered my '10 SE 1.5" drop with:
SVT shocks/struts damper kit
M-18000-ZX3B -Ordered from Tousley Ford
FORD RACING 2006-2007 FOCUS PERFORMANCE SPRING KIT M-5560-ZX3B
*I got the springs off Ebay. They are no longer produced.
* If you can't find them then you can look for these springs instead:
M-5560-ZXM1* these may ride a bit stiffer than the SVT springs.
I did none of the labor. A shop did. I like the result: better look, better handling.
No idea on exhaust since all I have is springs/struts and Steeda short throw shifter.
But FSWerks Stealth seems to be popular as far as exhausts go.
