Well, we got them to fit!!

With only a few tweaks and some inner fender massaging, we got the giant M&H 390/40/17in tire to fit our s197 2011 Mustang. Our Billet Specialties Rims are now 11.5in wide.

Attached are some PICs that reveal how they tucked under pretty damn well, and just plain fit far better than most would have expected giving the size of this tire on paper.

As I said before; we know these cars can hook and achieve killer 60foots on smaller tires. But this is by far a tougher look, fills it out in a big way. And the rear tire is clearly tastefully slightly taller than the front tire, the rear tire has slightly more side wall then the front.  And all the wheel well gaps, openings and fitment are nailed; plus they look more proportional than ever... 

Additionally, we hope to get great traction and 60foots even in poor track conditions as I originally stated about this whole deal with this particular size tire.

Looks bad ass!

Wow...I never thought they would fit...Nice job with the "shoe horn "

Those were meant to be on that car.

Nice

Looks killer

390 on a 11.5" rim ?? Doesn't sound good at all but it looks like it fits that rim perfect.

Nice work Lid!

What size are the fronts Lidio? Alternative Auto Performance

Looks like a huge amount of backspacing. What are the measurements on that wheel?

The Alternative Auto 2011 5.0L Mustang took a backseat to a couple of other shop projects during the 2017 season after trying to carve out some Hellcat and other Hemi work the past year or so. The shop’s 2011 5.0L car is going to finally get some updates and changes, and not get benched for the 2018 season.
For starters, this car left off in the 2016 season with a best ET in the very low 9s (9.19 @ 152+MPH (Boost only). 

As a recap it has a forged coyote motor, 2.9L Whipple GEN-2 @ 17-18psi, e85 fuel, stock TQ convertor, Comp Cams stage-2 cams, 3.55 gears, and totally stock suspension from front to back. With the intercooler water/ice tank in the trunk filled, the overall weight of the car is just over 3750lbs with driver. The all stock and factory original 6R80 automatic trans and Torque convertor have just over 20k miles on them, and neither have ever had an issue with over 750rwhp for several seasons, to currently 900rwhp on boost only.

Several things are going to get enhanced on our 5.0L car for the 2018 season with the biggest and most anticipated change being the latest offering from Whipple. We are going to be swapping out the existing 2.9L GEN-2, for the much more efficient GEN-3 that has been released at the tail end of 2017. We are going to also upgrade from 1-3/4” headers up to 1-7/8” size tubes.

Additionally, we are going to change a few things in the rear suspension to promote “anti-squat”. Which will get the car to spend less time & energy over squatting the rear, and promote more enrgy to getting the car moving forward much quicker, and also better ETs. I’ve been a very big advocate of leaving all the stock suspension alone on the 2005+ Mustangs as they will hook up, pull wheelies and do most of what we want as long as the back tires works when they have descent power levels. 

But there comes a time where some of this simply needs to be changed around a bit in order to make them even more efficient off the starting line at this power level, although recently we have achieved some 1.35 sixty foots with this car while still using a 100% stock suspension with only changes being 17in front runners along with a M&H 17in rear tire(325/45/17).

Along with some power and suspension upgrades planned for the 2018 season on this car, we are also going to try to do something that is unprecedented with the back tires. We are going to try to fit a very large M&H drag radial tire on the back as best as we can and keep it looking tasteful. The tire size is a 390/40/17in, only available from M&H.  That is not a misprint! It is a 390mm wide tire and is about 29.2” tall. 

We are going to widen our current Billet Specialties wheels from 9.5” to 11.5” and try to force and stuff-in this much bigger tire as much as we can, so that it simply looks tasteful, correct, and doesn’t stick out at all. We are preparing and planning on having to modify and cut up some of the inner wheel well, remove the dust boots from the shocks, and also cut off the useless axle bump-stop snubber pad under there too.

Some will argue that this car like many others does not need this much tire in order to run the numbers we’re looking for (this is true). But my overall goal with this bigger tire (at over 900rwhp)is to hook-up and run good numbers all the time not just at exceptional track days, major events, and private rentals, but to hook-up and achieve great traction and 60-foots all the time, under most average and typical track conditions that we are mostly subjected to when having fun at the ¼ mile.

Excited to see the improvements with the Gen 3.

I want lol

Hopefully the fat tires will look as well as the 345’s did on your white MACH.

I was wondering if you were getting tired of the mustang,i think well be back in the summer for a tune,same car different motor

So glad to see you putting some effort back into the mustang

Brian Buck

Great work Lidio! Look forward to next seasons times.

Good stuff. Although a 29.2" tall tire will help with that 14.8 final ratio and the 6R80 tuning, I think a 305/17 with the MT "R" and less rear gear would be the path I would take - as it's just a gear swap away and that "R" radial has been proven to the 1.1 sixty zone. More stall speed RPM, and 2" headers too - why have to redo mods 😉

Scott Hasty - your tuner is coming for that ass!

💪🏻 Get it son!! Can’t wait!! 🤘🏻

These are some unbelievable numbers, on a mostly stock car Lid! Well done my man.

Great job Lidio

Before the season ended for us here in MI -- we got the car out in some good and much cooler Fall air, (mid 40*s) and tested out the JLT unit and also benefit from some much cooler air. The results have turned out great so far. We ran numerous 9.7’s at over 142mph and then our very best was a 9.68 @ over 143mph… which we backed up with a duplicate run.

We believe the JLT was responsible for most of these gains in MPH and ET since our previous best of 9.77 at just over 140mph. The traction was great, but could have been better, so I’m continuing to not “slam” the throttle off the starting line with only about a 1300rpm brake torque. 60-foots were in the low 1.4’s and could have been in the very high 1.3s with a little more traction and pushing the car harder on the hole-shot.

These numbers were achieved with a full weight car and no front runners. All shifts have been at or just over 7000rpm for the entire 2017 season! With no trouble at all.

Nice !!!

Great, thanks for your work testing our product.

What's jlt

Dave Seilicki

Awesome...

Why not run without JLT yesterday since there was a weather change so we can compare Apple to Apple weather and mod? Or did I misread your 9.77 run

Rich Lictawa

She runs good going have get mine to the track in the spring

Msu Gotti here you go...this is what i need

Alternative Auto is very happy to announce that we are working with and testing what we feel will be one of the best ever AirBox assemblies for the Hellcat Vehicles.

JLT is known for producing some of the best performing and best fitting AirBox kits we ever worked with for many other applications -- Primarily Fords and Mustangs for us. We now feel that they’ve come up with a great AirBox upgrade for the Hellcats.

The most important feature that JLT has embraced and worked with on the Hellcat’s is they’re AirBox kit does not inhibit the stock “cold-air”, or “Ram-air” features that these cars come with.

We’ve learned with some testing that although several of the other aftermarket Airboxes out there for these cars will show some very impressive gains on the Dyno, as much as 30rwhp, they do not pay-off  where the rubber meets the road.  We’ve found that some of them do nothing for gains at the 1/4 mile and in the real world. And, some will actually harm real world performance outside of a chassis Dyno due to the fact that they are simply “very open” under the hood, and allow hot fan wash, and hot under hood air to get into the inlet assemblies, thus hindering performance.

The key feature we’re looking forward to with the JLT is primarily that it is sealed once the hood is closed, and makes full use of the stock Ram-air features. We are even going to experiment with the stock hood vent opening, with it both open and blocked-off at the local ¼ mile while testing.

So far (like other units), we are very pleased with the Dyno results. Our Hellcat, for now is leveled off and limited to about 830rwhp on e85 fuels. We’ve peaked as far as we’re concerned with essentially Bolt-ons because of the stock fuel pumps limitations on e85 fuel at 7000+ RPMs. Average DynoJet runs on ours is about 825-830rwhp, And just bolting on the JLT has bumped ours to 852rwhp... very solid gains on the Dyno so far!
