One of the great things about being part of the forum is the continued opportunities to hang out with Ford GT Team members. I had a great time doing that today.

Scott Ahlman, who was a Ford GT Chassis Design/Vehicle Dynamics and Development Engineer, has been hard at work putting together a new performance suspension package for the Ford GT. I know he's mentioned it here on the forum in the tech section. Mark McGowan, Mr 211 mph, recently acquired a beautiful stripeless black GT courtesy of The GT Guys. Of course it only made sense that Scott's work meet Mark's car and driving. I met up with the guy's this afternoon down at Cayman Dynamics down in Dearborn and took a few photos before we headed out to the Ford Motor Company Dearborn Development Center to thrash on the newly set up system.

I'll let Scott fill in the details, but I just wanted to say right off the bat that this is a truly impressive, fully engineered, data driven performance package for the GT. The sophistication and attention to detail here are really world class, and it's a privilege to have guys like this that care enough to still be doing this stuff all these years after the car was produced. Not only is the setup beautiful, but it's the culmination of the expertise, input and hard data analysis of the people who know the car best. I know it's not for everyone, but I love just being around watching the magic happen. Sorry, the pics aren't great but the light from the open bay door on an overcast day was overwhelming against the inside of the small shop.

Mark's new car getting ready for action, with additional Ford GT vehicle dynamics alum Chris White setting up for data acquisition:

Looking good. A really clean (except for the literal dirt from testing) setup that requires no remote reservoir even on a 4-way adjustable.

Easy to adjust on the fly. 40 click low speed adjustability on this package.

After we left Cayman Dynamics, we went out to the DDC and Mark put the set up to the test. My first thought was "Oh my God, that stripeless black GT looks incredible blasting across the VDA." It is just such a mean looking car, and the new ride height makes it even more angry. Mark put the car through a battery of tests, tossing the car violently from one direction to the other. They ran the car around the 200 ft circle. Pretty much exactly the type of vehicle dynamics engineering these guys were doing for the OEM Ford GT requirements, only with a much higher performance level in mind. Someone, and we'll never know who it was eventually spun the car. It definitely looked good doing it. In between runs, the car would come back, and Scott would utilize Mark's input and make changes. When they decided they had enough info to go on prior to analyzing the hard data, it was off for additional testing.

We then headed over to a series of ride lanes where Mark tested the setup against a number of different real world tests. Primarily these involve various levels of road quality that mimic what you see on a day to day basis. I went for a couple laps with Mark and one would make your chest and head bounce, one involved running over a series of steel strips at 10 mm thickness intervals, and other similar experiences. They skipped the horrifying huge rock course, but the OEM GT program didn't. If you ever want to cringe, see if someone can get you in at the DDC and look at the massive gashes filled with steel edges they ran GTs over. The worst one was a replica of a really, really, really awful condition railroad crossing. It was a huge mess of craters going over it. Again, Mark skipped it obviously, but they did that during the GT program. Oh, and they didn't just do it with a GT. Because of the inane requirements of FMC that apply to everything from an Escape to the GT, they did it to a GT being dragged by a wrecker, just in case it happened in real life. Painful.

I have some great video from the GoPro we put inside and out on Mark's car, but FMC has to view the footage first to verify nothing secret is involved, so as I get my memory card back from them I'll put it up. We had permission to film so shouldn't be a big deal.

******

My first take on being in the car with the Ohlins setup is that it's a very, very good improvement on the stock ride and handling. There was none of the noise you sometimes get with a high performance shocks setup. It was exceptionally stiff for performance and was actually really, really compliant on the ride handling roads we went on. That's definitely a best of both world's situation. I thought for sure it would be a lot more painful as we blasted down the ride roads, but it was actually quite nice. And then when we made a quick blast on the high speed test track, I said to Mark a) it's alot less scary when I'm a passenger in his car rather than Camilo's and b) wow did that feel good at speed. I can't wait to be a passenger on a track with one of these guys with this setup. Of course, I'd be remiss if I didn't mention how much I love the way it looks. It just looks like a really high quality, clean setup, so if you're into the jewelry, here's another piece for the wishlist. Oh, and these things are LIGHT. I picked up the stock piece in one hand and Scott's in the other. It was an easily discernible weight difference that will clearly help at the corners overall.

So that's the story for today. Ford GT Team - still hard at work, making the Ford GT better everyday. Be sure to keep an eye out for more information from Scott and Ahlman Engineering. These guys know they aren't selling 100 sets of these things, so they are doing it for the passion for the car, in response to the passion the customers display for the performance. You won't get this level of interaction and support anywhere else. I doubt many Ferrari guys get to say they called the OEM engineers for track day or street setup advice on their adjustable shock setups. Hope we support them! And of course, come to Ford GT Rally 8 and buy these guys a drink for their continued work on our behalf.

Looks like a Pre production car!
Scott is a brillant guy.I'm sure his products are 1st rate like himself!
His wife isn't bad either!

I knew McGowan wouldn't be happy without some kind of mess of gauges and sensors filling up the cockpit.

It's spectacular to have the original development team still out there making improvement to 'their' car. That just isn't happening anywhere else.

Amazing!

1. What is the small blue strut?

2. Does Invisible Glass work?

That is the most obscure and arcane vanity tag I have ever seen. I'd have guessed something like "get out of my way F***TARDS," but Mark is too nice a guy for that.

It was some kind of measurement tool they were using.

Sorry for the delay guys...I have been busy moving an air frame and Lotus Elan with McGowan out of his basement!! And the air frame back in!

Thank you to DBK for the great post and pictures and thank you for the comments guys - even Roketman! :>) It has been a great few days with many supporting this project for about 2 months. I will work on listing the great team in the next few days and high lights on the package and testing. Especially Mark McGowan, Chris White and Cayman Dynamics...many to mention and will.

The blue piece next to the shock is called an LVDT, which measures shock travel and velocities to see travels, including exactly when we engage jounce bumpers and shock velocities for every event. We are measuring speed, 3 axis accelerations, 3 axis rotational velocities (yaw, pitch, roll), vehicle position (GPS).

We ran all of our testing on the Bridgestones everyone is running.

I will be providing fully integrated packages and settings- shock settings, spring rates (installed for your ride height), jounce bumper and one other adjustment I will talke about later (about 4-5 packages) for street to aggressive track including straight line high speed mode.

Fortunately, predictions on shock curves, adjustments, spring rates and jounce bumpers and gaps have been dead on so far. The 4 way shocks have 40 clicks for low speed compression and rebound and 50 clicks for high speed compreesion and rebound. We could easily feel and affect the car with 2 click adjustments yesterday.

We are running high speed runs tomorrow for shock adjustments for power down and stability along with checking out two other packages.

The custom shock mounts and bar pin I designed are CNC machined and clear anodized 7075-T6 aluminum (stock was 6061-T6). The upper spherical joint is a very special joint from aerospace that is teflon lined with a hardened stainless ball and race. Not remotely the normal racing/competition sphericals.

I changed the stock shock curves a little and it worked out great for ride and handling. I will let Mark post his comments, but he was surprised by the fact that he couldn't tell I replaced a bushing with spherical!

Plenty more info to come!

Boy’s we are getting the band back together, all we need is Jeff Walsh and Jamie Cullen and we are ready. What a week, shades of the vehicle dynamics days of GT for sure. You need to understand that Scott has spent months using the original data as a starting point for his suspension project. We froze the design in 2004 for production so it’s been almost a decade since a real development has been done on the car. All of the development is being done on Bridgestone’s as they look to be the tire of choice with most Ford GT Forum members. Then Scott needed to find someone stupid enough to loan him a car for week or two so he could instrument and trash, thanks GT Guys for making it possible to own the car. Like I said I plan to drive the car, my ideal of driving may be a little different than most but it is fun. So the moons and star all got aligned last Tuesday when we delivered the car to Cayman Dynamics to start the instrumentation and tire change. Chris White (one of my dynamics engineers on the GT program) and Scott worked till 11 pm every night till we started the base line runs late Friday afternoon. Instrumentation is critical in this type of testing and getting that much on a car in under 3 days is unbelievable, remember this a my personal car not a prototype that you just hack and whack on. Right out of the box the setup is amazing remember we are on Bridgestone’s and the ride is every bit as good as the production and the handling is far superior than production. And that is just the standard ride rates and heights. The setups keep going down in ride heights and up in wheel rates and the handling keeps getting better. And yet the ride is still very good, we all were convinced that when we went to the rod ends on the Olin’s that ride isolation and impact harshness would suffer but it does not, very impressive. Small changes on the Olin’s yield big changes in how the car behaves. It is a very tunable setup and we are not done yet, more testing tomorrow. Can’t wait till tomorrow like a kid on christmass eve.

This thread has already achieved epic status. Please make it a sticky. Better yet, create a hall of fame category.

Dave thanks for posting.

Cost - I am finalizing pricing right now, but it wil be close to the following:

$5800 + shipping for a full set of the 2 way adjustable shock (low speed compression and rebound - 25 clicks each - hundreds of pounds of low speed adjustment range)

$7800 + shipping for a full set of the 4 way adjustable shock (low speed compression and rebound - 40 clicks each, and high speed compression and rebound - 50 clicks each) We are running the 4 ways for this testing because I can adjust it from settings for stock spring rates and ride height to twice the spring rate and 1 inch down ride heights. That is a huge range. This is spring rate range is not possible on a low speed only adjustment scheme.

I will be specifying about 4 packages. I will have (and somewhat prefer) installed spring options for your requested ride height and have to finalize pricing - including stock colors from Eibach (red or silver) and custom colors. And helper springs for the stiffer spring setups.

Timing
If I can come to an agreement with my prototype CNC guys for a production run in the next few days I will be ready to start shipping in about 3-4 weeks. However, that is a big if at the moment. I was planning on running about 10 sets (obviously has a big effect on my pricing at this very low volume), but have no idea the demand at this point, so the more people can let me know if they want a set close to the above pricing will be very helpful. I will keep you posted on my status. I also have to write instruction manuals and dot a few more I's, but the 3-4 weeks is very doable based on all the prep work up to this point. I owe one Forum member 2 sets ASAP! A mistake I made on machining my logo on the eyes and one other change set me back a few weeks.

I will post a write up the shocks in the next few days...2 more days of testing configurations.
