After reading about everyones experience with Griggs I gave Van at Revan Racing a call and he hooked me up with an incredible price on a slightly used front GR40 SS setup.

Well after going back and forth in making my decision, I pulled the trigger and bought the rear GT40 TT setup also! Torque arm, Watts link, Koni Adjustables etc. Went with alittle higher spring rate to make up for my stereo system for those that were wondering! I met John Grigg's today at his shop and talked to him for awhile before loading up my parts! Really nice guy!

I can't wait to get it back and try it out! I'm leaving the stock Pirelli's on until I can drive and make a fair comparison. Once I get it back and drive it for a bit, then I'll put my Nitto NT05's on.

Also as an added bonus, The Bone bought me lunch and we were able to hang out for awhile on my way back! Thanks again Art!

Thanks everyone!

Took my wife out for dinner tonight and she wanted to take the Shelby. Got on it after being on the freeway for 20 miles and broke it loose at 65mhp! After the sideways action stopped, I explained to my wife that the Griggs setup will help eliminate the sideways action of the car in a straight line on hard acceleration. She's not so mad at me for spending the money now! :lol:

He lifts it from the correct points every time I have seen it on a lift. From that pic though, I can't really tell where he has it lifted from today.

Thanks!

I love the front brakes! I just can't justify spending 4 grand on the rears for marginal improvement in performance.

Nice, what setting are you going to go with....

Thanks! Not sure I'm understanding your question right though JTB.

I am going to start off with the same ride height in the front as I had with the Eibachs and raising the rear 1/4-1/2" above the front ride height. I think that's a good starting point. Griggs says they like to see a 1 degree rake to the front.

If your talking about the rebound etc. in the Koni's, I'm going to leave them where they are set right now and go from there depending on how it feels.

If that wasn't what you were asking, I'll try again!:doh2:

From my understanding, yes you can buy this as a stand alone piece along with the associated hardware. I believe it's around $900 if you buy that by itself. You will also need a tech who can install and do welding as I believe there is some welding involved with that piece. I'm sure Van could answer that question completely.

You can buy everything individually. Here's the link to the TA. http://www.griggsracing.com/index.php?cPath=4332_4309_4320_4328_2040_3675

And yes as CH53 said, there is welding that has to be done. If you looking in the pics from last night, you will see the one where the X pipe is showing and there are two parts that have to be welded where the front of the TA attaches to the frame.

Some Torque Arm info....

What will the Torque-arm do for me?

It will increase straight-line traction.
It will provide more rear grip during cornering.
It will improve corner-exit acceleration.
It will provide superb control and predictability.
It will increase wet weather traction.
It will improve ride quality.

What is a Torque-arm?
It is a long suspension arm that attaches between the rear axle housing and the chassis.

Is a Torque-arm okay for street driving, or is it just for drag racing or road racing?
The Torque-arm is great for all three situations. Increased rear grip helps in every type of driving; would you ever complain about having too much traction?


I put one on my Track Car and it makes a major difference.

...I would think the torque arm would require elimination of the UCA since the LCAs now become locator links and the non-parallel design of the S197's UCA would otherwise cause serious binding with a torque arm. I would also think you'd want to set pinion angle pre-load to zero since the torque arm virtually eliminates axle-wrap. It should also maximize life of DS joints since the constant compromise of pinion angle pre-load is then eliminated. The torque arm clearly adds some unsprung weight (vs a UCA) but with all the other Griggs or comparable pieces surely would seem to pay back in terms of excellent axle control and handling. I've never driven a car with a torque-arm but I really like the concept a lot.

---

Conceptually, a control-blade type IRS uses dual outboard short torque-arms -- one for each wheel hub. Since IRS pinion angle is engineered as a function of center section mounting, long heavy arms (necessary to minimize pinion rotation as a function of suspensioon travel on a live axle) are unnecessary and no other control arms are needed since the outboard torque arms serve both fuctions. The control blade IRS design has proven to be extremely robust with substantially less unsprung weight than a live-axle torque-arm configuration. The Aussie Falcon's (Dana-engineered) control-blade IRS (http://www.themustangnews.com/tech_06/st-0706_ozirs.htm)is made from low-cost stamped production pieces and has proven near bullet-proof even at very high SC'd HP levels and over all manner of unpaved back-country Australian roads ...and in competition. If an IRS is ever done for the 2014 Mustang, that's the design I'd really like to see -- best of both worlds it would seem.

Why do FORD not use these Torque Arms on Factory Hi-Performance Stangs?

I don't even think FRPP offer them...but I'm not sure.

Mass produced these would be inexpensive to manufacture with significant handling benefits benefits, the only downside is it looks like that set up weighs a lot.

I was told by a Ford engineer that they do not reccomend a torque arm on the s197 chassis because the center floor board mounting point area is not built strong enough to support the stresses that will be transfered there with a torque arm.

.....just relaying what I was told three years ago when I asked about it.

It's also why he didn't recommend changing the UCA mounting bracket as the OEM one is meant to be the weak spot vs. ripping the floor board out.

I suppose anything is possible, but I have yet to hear about any sorts of issues with the Griggs TA doing that.

Plus, I thought the Griggs torque arm mounts to the frame and read axle housing and not the floor board? You probably know better than me since you're having the install done right now.

This is where it is welded too.

On my 2002 I welded in full length subframe connectors, then welded to it a supplied cross member that the torque arm connects too.

So the stress is transferred through all that.

I'm sure similar reinforcement can be done w/ a GT500.

Well the s197 chassis is alot more ridged then the s95 so there's a big difference. Also, from what I have read, they are saying that subframe connectors etc are a waste of money for these chassis.

Didn't BadBoy install the sub-frame connectors in his KOS entry car?

...maybe subframe connectors are less important with the torque-arm since it takes a lot of the thrust too (not withstanding George's comments) but I think they are important (welded-in) for serious drag set-ups with big stickys. The tortional rigidity of the S197 is excellent.

The "instant-center" is adjustable with control arms (the projected location where UCA and LCA angles cross) but is fixed with a torque-arm (the mounting point), tho I'd bet the Griggs set-up places it pretty darn close to the mass center for most set-ups. Still, I'd bet the center-of-mass varies somewhat from a stripped 3050# racer to a 3900# streeter, so it's a chassis-tuning consideration that is no longer available, however that may be outweighed by how effectively torque is transmitted and the fact that "instant-center" tuning is less important on a road-racer whereas it's critical on a drag car -- hence finely adjustable 4-link setups etc on the latter.

Not sure. But Badboy 1/4 miles his car. Griggs is more for road course and less for the 1/4. At least that's from what I have seen. Most people that use Griggs stuff, actually turn their car when going fast! :haha: (just kidding all you 1/4 milers!)

Not saying if it would help or not, but from what alot of people smarter then me have said, it's not needed on the s197 chassis.

It's been in the high teens and low 20s every morning this week. Florida. Must be really cold up north.

The engine loves the cold air. The tires, well ...not so much. I've been especially careful in the mornings driving to work.

To get back on topic, thanks to this thread I've been wanting to run out and buy a torque arm all week. ...but then I'd need a watts link, and springs/struts, and LCAs w/relocation brackets, etc...

Well here is a quick write-up on my experience so far.

I have put about 15 miles on it. When I took it for a test drive, I immediately noticed that the steering felt firmer. I'm guessing that is because of the new bushings being used in the front end.

On the freeway the car seems very planted. It didn't feel bad before by any means. Now if just feels solid. Very solid. Rolling parts of the freeway that would upset the car now does not bother it at all.

The front end feels like it give more feedback now. You feel small stuff in the road that you wouldn't have felt before in the wheel.

As for forward grip, WAY more then before. Now at 45-50 is just seems to drive forward. Little if any wheel spin. Before I would break it loose at 65 no problem. Mind you I haven't beat on it yet and this was more of a shake down drive.

In first and second when you break the rear end loose, it still drives forward and doesn't seem to want to swap to one side like it did before. It feels much more stable and controllable.

I was able to take some good corners that I have taken many times before tonight. First impressions are that body roll is greatly reduced. Car seems to be almost flat in the corners and has very good feel.

As for road noise etc. I haven't noticed a big increase in mechanical noise. I have very little increase in any noise. I can hear the suspension working more then the Eibach setup, but it is in no way a huge increase in noise. Sounds about the same to me on the freeway and around town it is a very small increase.

Now here is the really cool part in my book, my wife loves the feel of the Griggs suspension! She said that in the passenger seat it felt much more stable. She said that before the car would scare her sometimes under full throttle due to the rear end stepping out so violently. Tonight there was none of that. If the rear did break loose, it spun and drove forward, not sideways.

That's all I have for now. Hopefully I'll be able to put some more miles on it soon, but they are saying that we are going to have some serious rain coming starting Friday for the next 5 days.
