Looks like the bumper cover from the Boss 302 will go right on the 10-12 GT500's single exhaust and all. Taillights too.

Is the launch feature the same as in the boss? What about rear tire size? Are they going to be the same as the current car?

I've responded almost every time I see someone say that the '10-'12 cars use the GT cams. I have yet to see proof that they are. Ford lift specs from a service manual - anything.

Steve @ Tousley Ford verified the part numbers for me because I wanted to know the difference in cams(if there was any).

The part numbers and price are identical.

Thats another reason why I want to know the part numbers and specs on the 13+ cams.

According to the Ford website:


SVT Performance Package
3.31 axle with TORSEN differential, unique wheels, R-Compound tires, Bilstein adjustable dampers, unique springs, unique interior touches, front fascia dive planes
SVT Track Pack
External oil cooler, transmission cooler pump, differential cooler, fog lamp delete, brake cooling ducts

R-compound tires and I wonder what the "unique interior touches" are.......but I don't like the idea of fog lamp delete

so the 5.8l has piston squirters even though the RPMs have been increased up to 7000? i thought they eliminated them on the boss 302 because the oil collecting in the piston was causing substantial windage/drag at high RPMs.

Ry, my mind followed the same logic regarding the squirters. Seems Ford goes back and forth with these.

The 7000 rpm Mustang GT 5.0 has oil squirters, so I don't see it as a flip flop at all. The Boss has a higher redline, plus was designed as the extended high rpm road race car. The oil squirters are very valuable in high boost (high heat) situations.

As for what I'd like to see as a retrofit (the original topic), I'd like to see the TVS from FRPP with Pro-Cal for the '11-'12. Definately the clutch and driveshaft, too! Torsen Diff..Recaro seats...Oh, and a 5.8 crate motor. :)

Maybe Ford is holding out for a mid-year release of a 10"-10.5" wheel for the rear but I wouldn't bet the farm on it. I'd finally be able to give the '13 my stamp of complete approval if they did. Note that it also looks like the rear caliper is not a Brembo unit but instead it appears to be the same Varga/TRW caliper Ford has been using for awhile. Again, I suspect that only the caliper bracket is new to allow the new, larger rear rotor to fit.

As long as Ford is still using a solid axle on the GT500, you will not see rear Brembo brakes, unfortunately.

The reason is on the 8.8, or any c-clip rear axle for that matter, the slight inwards-outwards movement of the axles will cause pad knockback. That results in a dropping pedal and inconsistant pedal feel, especially on a track.

Ford has been using the same cast iron, single piston rear calipers on the Mustang since 1994. To say they are outdated would be an understatement. However, they are ideal in this scenerio because they are floating calipers, which minimizes piston knockback due to the floating design, and they incorporate the e-brake mechanism, which prevents the piston from being pushed back into its bore as the axles move.

Looks like we'll have to wait until the next generation IRS GT500 for a 4 wheel Brembo package.

How do they offer big brake upgrades then? I'm just curious if people would have issues with big brakes in the rear.

They may incorporate a type of c-clip eliminator kit, which uses pressed on axle bearings instead of c-clips to retain the axles in the housing. Then there is also the problem of a parking brake, which is eliminated when using fixed calipers. So some type of drum-in-had or separate parking brake caliper must be used.

Those kits are not OEM in terms of durability or longevity though, and most are only recommended for drag racing (straight line only).

Basically, Ford (or any other OEMs) are not willing to use fixed rear calipers on c-clip solid axles due to axial movement of the drive axles.

What site did you read about the r compound tires? That could be a serious game changer on a PP/Track Pack car.

This says it's the same tires on all the models

Judging by their site, the GT500 at the show and in all of the pics is just a base car. It has fog lamps )so no track pack, and it does not have dive planes, so no PP. It certainly looked to have a cooler of some sort in the upper grill in some of the pics, so maybe the specs are not fully ironed out yet.

I WANT PICS OF MORE COLORS and PRICING INFO!!!!

The motor on display in LA says Ford GT cams.

Parts number wise I see the following...

Ford GT cam part #'s

4G7Z.6250.AA RH INTAKE
4G7Z.6250.BA LH INTAKE

4G7Z.6250.CA RH EXHAUST
4G7Z.6250.DA LH EXHAUST

Shelby GT500 cam part #'s

YL7Z.6250.BA LH INTAKE
YL7Z.6250.AA RH INTAKE

YF3Z.6250.DA LH EXHAUST
YF3Z.6250.AA RH EXHAUST

The Terminator cams part numbers are the exact same as the Shelby's.
From here.

In mid '07, Eric Brooks states that '03-'04 Cobra cams are the same as the GT500 cams (we can assume he was looking at '07 GT500 specs for sake of argument and I think we can all agree they were the same at least through '09, yes?).

Guys,

I just got my hands on some very interesting information.

The 2003 Cobra and the 2007 Shelby have the EXACT same camshafts.

I have been under the impression that the Shelby had the Ford GT cams.

Those cams spec at 240/250 duration, .360/.396 lift (using a 1.81 ratio follower), and 114* intake c/l.

The Ford GT spec out at 242/247 duration, .438/.447 lift, and 115* intake c/l.
From here.

One week ago, in the same thread as above, Michael at L&M states

Eric is correct, the 03-04 Cobra cams are the same as the GT 500, including the engineering revision numbers.
From here.

Michael makes no distinction between '07-'09 or '10-'12 cams being any different or any inference that late GT500 cams spec the same as the old GT cams.

You mentioned Tousley, and I found a thread where they stated

Yup, FRPP reinstated the M-6550-GT cam kit and we have them in stock.

$418.00 a set plus shipping. :)

link to the FRPP page on these,
From here.

While the cams from FRPP are no longer available, the FRPP page linked states...

Original equipment camshafts for the Ford GT supercar

- Direct retrofit to the 2007-2009 Mustang SVT
- Increases lift from the stock 10 mm to 11.14 mm intake and 11.36 mm exhaust
From here.

If the GT cams were the '10 and later GT500 cams, that would mean that the lift on each cam was over 1mm more (can anyone find the OE specs for a '10 or later GT500?).

I guess the bottom line is this...if they were the same, anyone looking for a set of the now unavailable GT cams could just order from the Ford dealer a set of '12 GT500 cams (for example). Because the inference here is that they are the same, right? Then why is MMR out of them and fairly recently at that?

Check this thread out to see what I mean.

And finally, where in your query to Tousley did they verify the late GT500 cams as being the same as GT cams? I only see you making the supposition (with no response to it from Tousley)...

Ironhand said:
According to what has been put out the new GT500s have upgraded cams. With the current generation using FGT cams then it has to be something else.

Can you guys find some more info and maybe dig up a part number for the set when it hits the showrooms?
From here.

Was there more correspondence elsewhere (PM's between you and Tousley) that verified what you are saying?

Wildman, I never said anything specific about the type of caliper, only who had been supplying them (Varga/TRW) as well as them being around for a long time. I should have been clearer. Ford contracted yet again (or so it would appear), for the '13 model with the same supplier. Brembo could have been awarded the contract at some point in time to build the calipers to Ford's specifications but that has yet to happen out back.

Or, Ford could have changed the design with some upgrades, such as going back to a pressed on bearing/retaining plate (ala the old 9" rear) and dumped the C-clips, but they haven't chosen to do that either. So here we are with different suppliers, once again, from front to rear.
