The IRS to my 2001 SVT Cobra is going out. I just ordered a 03/04 IRS from ebay for $1,500 + shipping($300) = $1,800. I also ordered new sway bar end links, sway bar bushings, and a Ford racing irs differential cover. Mine as well get those replaced before installing the IRS. Now once I make all those changes and install the IRS I ordered from ebay. What difference will it make for my car? Will my launches be better? Will I chirp all the way to 3rd, 4th gear? lol.. I hope im doing the right thing here. I dont plan to race/abuse my car. She is my baby and I plan to take great care of her. But ever now and then a little rice rocket or muscle car may pull up trying to show off. :nono:.... Any advice will be great. Thank you very much.
