Some pics of the 2015 Mustang's dirty bits May 04, 2015, 07:04:19 PM Being a long-time car guy and a mechanic to boot, I simply had to see the underside of the new Stang. Some of you guys are probably curious to see what the new independent rear suspension looks like in the S550 as well. I finally had the chance to get it in the air yesterday, so here are some pics:First a "wide" shot showing the whole rear suspension.The rear suspension. Lower control arm and spindle are aluminum. Toe link is stamped steel. Upper arm, what I've always called the "Boomerang link" in other vehicles, is cast iron.Rear diff is the familiar 8.8" with an iron housing and structural aluminum cover. The ring & pinion are 8.8 (it says so right on the tag) but it looks differently shaped to me, kinda like a Dana 44. Gears inside are 3.31:1 with traction lock. Quote Selected
Some pics of the 2015 Mustang's dirty bits Reply #1 – May 04, 2015, 07:14:36 PM Here's a closer shot of the rear diff cover. You can see what I mean here when I say it's not shaped like the usual 8.8. The bolts are not symmetrical, and the housing almost looks stretched on the right hand side, like the aforementioned Dana 44Here's a straight up shot at the rear diff. It's mounted in 4 places - two on the cover and two on the iron housing. You can also see some of the stamped steel rear subframe, and how the exhaust passes under it. I didn't measure it, but it looks like 2.25" pipeRear brakes and suspension. The rotor is large and vented, but it's vented the opposite way of what I'm used to seeing. Most rotors have a solid "hat" and the venting is from behind. These ones are vented in front. Caliper is a standard single piston with integrated parking brake, just like the old TC calipers. Stabilizer links are aluminum with tie-rod-end style ends, similar to the MN12 T-Bird's front links Quote Selected

Trans crossmember is cast aluminum. The driveshaft is two piece, with a rubber coupling (similar to European cars) up front, a U-joint and support bearing in the middle, and a CV joint at the rear. Front subframe is stamped steel. Engine mounts are aluminum. There's actually quite a bit of room in around the subframe/engine mount area. Oil pan is (surprisingly, to me) stamped steel. Steering rack is electric. A/C compressor and alternator are mounted down low, unlike the old modular engines which had the alternator high and center.Front suspension. There's a lot going on here. Two lower ball joints connected to two lower control arms, it strongly resembles the front suspension of my Chrysler 300 (and also the Ford Fusion). It differs from the 300 in that there is no upper control arm - it's still a McPherson strut setup with coilover spring. The tie rod end is actually mounted lower than the ball joints and the (cast iron) knuckle has a very stubby arm, probably to help reduce turning radius. Quote Selected
Some pics of the 2015 Mustang's dirty bits Reply #3 – May 04, 2015, 07:32:15 PM Another view of the front suspension. Here there be dragons.And brakes. This car has brakes for days. Not sure the diameter of those rotors, but they are massive. My brother's 17" winter alloys won't fit over them (I tried, out of curiosity). Calipers are fixed type (non floating) 4-piston aluminum housing. Rotors are the same reverse-vented design as the rear. These brakes are bigger than what you'd find on an F150. And they're the base GT brakes! The optional Brembos are bigger still, with 6-piston calipers!Whoa. Serious whoa. Quote Selected
Some pics of the 2015 Mustang's dirty bits Reply #4 – May 04, 2015, 07:35:27 PM Hard to make out, but the stock headers are Tri-Y type with what appears to be 1-3/4" primaries. They make the old 5.0 HO headers look positively y: Quote Selected
Some pics of the 2015 Mustang's dirty bits Reply #5 – May 04, 2015, 09:24:40 PM Very informative--with great pics and writeup. Thanks.It looks like the engineers are car guys that listened to us regarding previous generations' shortcomings (or at least non-optimal designs). I can see quite a few things I wish our Foxes would have had from the factory, and not just the IRS and big brakes...Daniel Quote Selected

Some pics of the 2015 Mustang's dirty bits Reply #8 – May 05, 2015, 02:59:32 AM Dollar wise, well beyond my means to experiment, but it makes me curious how those calipers and rotors might mate up to SN95 spindles....Not that I have a set of what....18" wheels (at least!) to clear those manhole sized sumbitches...Nice pics. Rust must spread up in NS faster than the herp on a porn set in the (hollywood) Hills..lol Quote Selected

Some pics of the 2015 Mustang's dirty bits Reply #14 – May 05, 2015, 09:27:21 PM I'll have to measure them. I've seen 13.8", 14" and 15". I think the 15" are the Brembos. I do know an 18" wheel would be the minimum - one of my brother's 17" winter alloys will not go over them. The wheel studs are larger as well - 14mm x 1.5, same size as the Pimp Sled and the Avalanche. Which, mentioning those, it has just occurred to me that I've got one each of the Big Three - Mustang, 300, and Avalanche. Also one each from the NAFTA countries: Canada (300), USA (Mustang) and Mexico (Avalanche) Quote Selected
