So I am dead set on keeping my IRS, and I am planning on installing FTBR bushings soon, but I am trying to figure out the rest of the suspension. My car will be a street/strip car that handles better than stock on the twisty back roads, the drag strip and the occasional track visit. Has anyone...
Hoping I'd have some luck for a straight trade, previous owner got rid of basically everything that made my 01 cobra, a cobra, including the IRS. Looking for anyone who would like to swap their IRS for my SLA out of a low mileage 03 GT, with 4.10s, new LCAs and stiffer rear springs. I believe...
What's up everyone. I've been on SVTP quite a few times but never made an account until now. I started out with a 1998 Laser Red/pink(ugh) GT and later moved up to a 2007 GT (don't hate me), and have since moved on up to my 2001 Mineral Grey Cobra. I can say without a doubt that the cobra is...
I've been meaning to sell this. It is Redfire red, but the color isn't all that great after being attached to the diff for a few thousand miles.
I got a new set of hardware from Billetflow to sell with it. The diff cover bolts are longer than the stock cover bolts so you need these to install it.
I’ve been reading the forums for all I can about the FTBR IRS kit, watching vids, etc., and I finally pulled the trigger. I ordered the FTBR IRS 5001 kit (kit + Delrin Rear differential lowering mount) along with the Ford Racing Reinforced IRS Rear Diff Cover milled for clearance.
Before I...
So I had my pinion seal replaced shortly after buying my car and I guess they didn't torque the nut correctly during re install and my pinion bearing let go which let the pinion gear eat the inside of the housing so I'm hoping some one near ga has a pumpkin that I can buy with out having to buy...
Looking for T56, computer, and IRS out of a cobra. Also selling all my Mach 1 auto goodies, my transmission was freshly rebuilt this week and cleaned up, never installed. The T56 could just be a shell, Im sending it out to RPM transmissions to have it built up. Also looking for a Cobra IRS, one...
Does anyone have a source for a new IRS toe link. I can't find a listing at any of the jobbers and Ford has discontinued the part. I need the drivers side and will purchase 2 if the right and left are the same.
Thanks, Tom
Want a more solid rear end? Just finished my design and first batch of 99-04 IRS Aluminum subframe bushings. Pretty tight fit, have to freeze them before they will slide into the IRS cradle which is exactly what I wanted. Turned out pretty sweet. Next step is to get them anodized and slap a...

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...
I have a complete IRS assembly out of an 04 cobra with 17K miles on it. Includes rear brakes with newer hawk pads. It has DSS Level 5 axles with about 2,000 miles on them and poly Steeda Differential Bushings with a Billetflow IRS brace. I also have a set of IRS specific Eibach pro kit springs...
Due to "clunk" in in the diff, I took it out and opened it up to measure the backlash. Result: 0,016 to 0,018 - too much (Ford recommends 0,008 to 0,012). I'm not quite sure what to do now:
1. Shim the crown so the backlash will be whithin spec. Leave the pinion alone.
-or-
2. Take out the...

Hey guys I looked around and couldn't find any info on this. I know I will have to grind the knuckle down to run a 15" but will it clear with the bigger toe links ? Has anyone run a 15" with the upgraded deluxe toe links from FTBR ? If so are there any additional mods to make them work? I...
Hey guys,
Just wanted to give a semi-brief shoutout to Bruce at FTBR (ac427cobra), even though im sure hes gotten this praise thousands of times already haha.
So my first impression was reading the complete guide on how to make the IRS in the cobras work for us rather than against us, it was...

I am testing the waters to see if there is any interest in a trade for my 99/01 amber tail lights for good condition Borla Stinger IRS catback (preferably polished). Tail lights are flawless and have recently been wetsanded and buffed, so the catbakc would have to be in similar condition.
I...
