Or, couple the Roush springs with the BAT or Spax struts. (1-800-59ROUSH). Roush springs are for the Cougar, but will fit our cars.
Some guys are putting the Roush with the ST200 struts, and while this is a very inexpensive option (if still available), the ST200 struts are much like the stock SVT struts, and I don't recommend this combo for longevity past 30,000 miles.
Otherwise, Roush springs, 120 shipped. ST200 struts, ummm, $120 for all 4, IIRC. Tempting.
