Sure Alex!
Most of the info is pretty up to date on our website as well.

The Watts Linkage is designed for 05-Current Mustangs with an 8.8 rear end, COUPE ONLY. The components are made out of 4130 Chromolly and it is fully adjustable to compensate for ride height (as you should have, just like on a Panhard bar), via the arms as well as the pivot point. We actually have adjustments on the diff cover to allow for your preferred set up. Our system is unique in that it works with an application specific engineered diff cover and a main brace set up, which spreads the load evenly over 6 points instead of just 1. This should make the unit much stronger and less likely to sheer a pivot bolt like many watts links of the market.

We also have integrated two oil taps on the front of the diff cooler for those GT500 owners and other customers who wish to use a differential cooler. It also uses the bearing pack load bolts so you can set some pre-load.

Vorshlag daily drives their Mustang outside of its SCCA duties and noted that it was quiet, comfortable and did not have any noticeable NVH, which was a major upgrade over their previous set up.

Let me know if you have any further questions!

Yes, we've been running the Whiteline Watts on our car for a few weeks including at the SCCA Solo Nationals where we placed 4th out of 33 in ESP in the only emissions legal street car (with AC, stereo and nav) out of the top 10. We've been REALLY happy with this bar and will be selling Whiteline because of their new S197 parts. We spoke to them at PRI last year and have been waiting for these. We also ran their companion rear sway bar and it solved another one of our big issues - inboard tire clearance for the 315 Hoosier. The Whiteline bar is completely out of the way of the tire and the only thing limiting inboard clearance now that we've inverted the Motons is the inner fender well.

We just bought a brand new 2013 GT base model to do a full no compromise build (no emissions, no AC, no stereo) for the E-Street Prepared class and one of the first parts it will get is the Whiteline Watts Link.

Looks like I found my watts, the taps for oil cooler as well as urethan bushings sold me. Price is perfect as well.

 

Are you being honest with the no increase in NVH? Because steeda also claims there is no NVH and there is a clunk over every bump. So far the only unit out there that really has no NVH is the fays2. Now this has a much better design and is lighter but if it actually does not increase NVH I am a buyer. But you guys need to gurantee this product that if it does increase NVH even when installed correctly that we can get a full refund.

Also in the pictures of your watts what is that carbon fiber piece above it?

 

How would you expect them to enforce a 'no increase in NVH' guarantee? Would you (the end user or consumer) be doing before/after testing that will involve decibal meters both in the vehicle as well as under?

 

No its very simple. If I have no clicks, clunks, rattles or w/e before the install and then I have them after that would be an NVH increase.

Jim fays honors his product for 3 months money back gurantee. I'd like to see other companies have the ***** to do what he does instead of just posting bs trying to sell their products with misinformation.

Like steeda their watts says absolutely no NVH increase. My friend with a steeda wats every time we go over a bump or stop the car in heavy traffic we hear clunk clunk clunk clunk clunk clunk clunk clunk

 

In all honesty if you don't want any increase in NVH you should just leave the suspension stock.

Whenever you go to something that uses stiffer bushings there's always the possibility of increased NVH. My Steeda LCAs with poly bushings are supposed to have no increase in NVH, but there is. But I knew that going in that it was a possibility. I didn't really care.

And I have the Fays2 WL, and there's a bit of NVH with it. Enough for me to care? No.

 

Well see thats not exactly right. Properly made street performance mods don't add NVH. For example all the roush stuff I have put LCA and UCA zero NVH. When installed correctly the fays2 makes zero noise. I have been in 3 cars that had zero noise after install.

But most of the reason at least with steeda poly LCA if there is noise its because of the build tolerances of our cars. So essentially if your car was made perfectly a poly poly LCA will not add NVH. But if something is off even a little bit you will get NVH. But that is why I chose not to risk it and got the roush UCA and LCA. Still a big upgrade from stock but no NVH.

The fays2 is the same. When installed correctly no NVH. But with steeda,griggs, or cortex it doesn't matter. They all have noise. Mostly clunks.

But if we are accepting that all mods add NVH then they shouldn't advertise their product as such.

 

you most definitely pick up some NVH from the Fays2. Its hard to avoid it with the metal on metal connections. Whether you hear it or not is another story. But with the F2 I definitely pick up more rear end noise since those axle clamps transmit some sound through the various rods and joints into the watts frame and then into the car.

I've been in 3 different cars with Fays Watts, 1 had minimal NVH the other two had slightly more. I think it comes down to the car some times.

 

Took the words out of my mouth. Count me as excited for this setup!

 

Yes thats true. But in my experiences the vast vast majority of reasons came from improper install.

And to the person above if there is NVH and you can't notice it then how do you know it increased?

The FRPP springs make the suspension 15% more stiffer. But if I can't feel that difference when I drive then who cares?

Also on your fays there are new o-rings made to eliminate the metal on metal noises you are hearing. Maybe you need to give Jim a call there.

 

You're misinterpreting me. It's not noise FROM the Watts Link. It's the Watts Link enabling more noise from the axle housing itself to transfer into the cabin.

It's not much, but since I notice it I can't say there's no increased NVH. Not that I care about a little extra NVH, though.

 

Ah I see. Hmm thats interesting the people I know have no experienced this. Maybe it was from improper lube or O-ring install.

 

It's a carbon fiber rear diffuser such as the ones shown below.

 

Well put.

 

It's very minute. I bet it exists in every Fays2 car but only **** folks like me ever notice. I can hear a smidge more gear/axle than I could before.

Now what really gets me is that I've got a pinion (flange?) issue where I've got horrid whine at 60+ mph. I think I'll just fix it with a new shaft, ring & pinion, and diff.

 

I am super ****. What kind of noise would this sound like? I have a kind of gear whine but its very tiny at 57 then stops at 61 mph. Its not very loud.

 

Just a sort of axles / gears moving in a tube type sound. Its dampened a bit so if you can pick it up its a faint hum. If you have exhaust or the radio on you'd have to listen closely for it.

 

Your first post? What a bunch of BS.
