Looking to put a rear brake Line Lock kit, or Staging Kit on the 03 cobra, What is the most bang for the buck? Do I need a whole kit or are the lines easy to bend and work with from a generic kit? Any advice would be appreciated.

Maybe one of you geniuses can help me here. I'm trying to wire in my Wideband for AFR into my SCTx4 tuner. I have followed the directions from their website, and tried a few other things, from SCT, but I get no reading on my X4. I will not go into great detail other than the basic...

03 cobra, high flow cats, cat back 2.5 magnaflow, 2.76 pulley, CAI, SCTx4 tuner with bama tune. Cruising AFR 14.5-14.7 from 30 mph to 75 on interstate. WOT: starts around 13.8 and creeps down to 13.4 up to 6500 rpm. Am I too lean on top? I prefer safe over a few HP. Thanks

Just got the 03 cobra back together, did all my projects I've been putting off until it was -5 outside and nothing else to do at night, started on these projects right after Christmas. Dropped rear cradle IRS, put new poly bushings in, what a pain-until you figure out the tricks, installed new...

Looking at: PLX SM-AFR Wideband + Multigauge Link Combo I've been wanting to put a wideband in the 03 cobra since I bought it, but, I'm not a fan of all the aftermarket gauges, not knocking them for all others, just not my style. So with this thing; I slap the old smart phone on the suction cup...

I'm installing LMR Poly bushings in my 2003 cobra IRS, I really don't want it sqeaking in a few months, should I mess with installing grease zerts or is just properly lubing them with correct grease when reinstalling enough? They are the black poly, not the super hard stuff the inbetween stock...

My winter project is to replace the rear dif cover with a Ford Racing one I purchased a few months ago. Since I'll have to drop the IRS, I was kicking around replacing some or all of the bushings on the rear IRS, the car is pretty much stock, tire and suspension wise and during car show...

I will be replacing my rear dif cover this winter when I take the time to drop the rear end. But, I will be doing some 2nd gear burnouts between now and then. Has anyone broke the rear half shafts with stock tires, no drag slicks or street drag radials? It is still IRS and I've not...

2003 cobra, still IRS, CAI, cat back, and 2.76 pully, bama tune. So, I'm just wanting a "car show" burnout setup that's a little safer than going form clutch to break. And I know, its dumb, and I'm old, and all that stuff, but hay, I'm just asking for info. Anyone have experience with a good...

Can someone point me towards a wideband that will be compatible to use with my SCT x4 tuner and or install a permanent gauge in the future if I decide I need it? Or does such an animal not exits? I was just going to put sensor in the drivers side header that is stock. Title is supposed to...

Looking for a little advice here, I just swapped out my clutch to a Mcleod RST, new Mcleod stock flywheel, new TOB (ford racing), new idle bearing (ford racing), new TOB sleeve it went in fine and input shaft centered perfectly, Put back together with .0038 shim way too tight-then to 36 too...

What did you do with the EGR tube?? Reference Thread. https://www.svtperformance.com/forums/threads/head-cooling-mod-thats-egr-safe.1091089/

OK, I realize this may not be the correct forum but, I'm kind of desperate and want some people to read who my know. I have the trans out of my 03 cobra, a new 26 spline input installed, McLeod RST clutch installed, and am going to reassemble tomorrow morning. I purchased the MMR head cooling...

Reviving old thread, any other issues? I'm doing same install but using a new factory Mcleod aluminum flywheel not steel. I have adjustable pivot ball and AMP 26 spline input shaft, I hope it's of good quality, it looks to be but...

Hello all, I'm sure someone can just rattle this off, MMR tech support is out until Aug 1. I am replacing clutch in 03 cobra with 40k miles on it, I have the MMR head cooling mod and was going to install with the trans out, this one below. My question is: Do I need to Teflon tape or anything...

OK, dropping the trany and trying to talk myself into our out of doing one of the head cooling mods to my 03 cobra. It's pullied, cat back, CAI, and a BAMA tune, that's it. So, for all of you who did or did not do the head cooling mod, any problems? Car has 40k miles on it, goes to 1/8...

Is anyone running a RAM 98951T PowerGrip clutch? Peddle pressure compared to stock? Car sees: Car show burnouts and track with street radials a few times a year, no drag slicks. 490 RWHP.

My 03 cobra clutch is starting to slip, it's pullied, CAI, Cat back, may do a little more and get to the 500~ HP range but not much past that. Should I replace the flywheel and the clutch or just the clutch, is their any benefit to getting a lighter weight flywheel? The current clutch in it...

I know this bridge has been crossed but I'm looking at installing some subframe connectors on my 2003 cobra coup, are the bolt on's any good? I was thinking of getting some bolt on's so I could install and setup in the garage then take to a shop with a wheel lift and have them weld them up for...

Is it too hard on the car to do a 2nd gear burnout? Stock 3.55 gears, trans, etc. Just pullied, CAI, Cat-back and tuned? Stock size W rated rear tires. Just wondering if a 2nd gear burnout is too hard on the car and should be avoided? First gear burnouts are smooth and easy, no wheel hop...

I have a tiny leak on the rear diff cover so I purchased a Ford Racing cover to put on, from what I've read I will have to drop the IRS out of the car to get it on, if I can do this without dropping the whole IRS please tell me how??? But, if I have to drop the IRS I was going to replace the IRS...

Ok, I know this is backwards, but, the PO put iebach lowering springs on my 03 cobra and it's really low, so low, you must drive with extreme care. Is there a spring kit out there that lowers the car .5 to 1" or a way to raise it 1", different isolators? And advise would be appreciated. I do...

Howdy all, I bought an 03 cobra about 18 months ago with 37k miles on it and the "paint peeling" issue. Just now got around to taking it all apart and prepping it for paint. AnyWho. It has a busted front bumper bracket and some bends along the bottom ground effects that are all IMO due to the...

Going to a fun run 1/2 mile, legal, run at an old Airport. 2.8 pulley, CAI, Cat back exhaust, lower springs 1.5", BAMA tune. What do you all think the cobra will do in 1/2 mile for top speed?

Took the 03 cobra to 1/8 mile drag track for "tune and test" runs and out of 5 runs I managed to hit 3rd one time, it was very difficult. So, which shifter replacement has worked well for those of you who occasionally hit the strip and need to do some quick shifting? I do and will use the...
