Well, I have a stock suspension and I just bit the bullet and purchased a Fayes 2 Watts link through the Shelby store. I am wanting a little more stability around corners since I do not desire to run 1/4 mile runs. Does anyone have any input on additional parts to compliment the watts link. Do I need a UCA? Do I need relocation brackets and LCA? Any help would be appreciated.

I assume that is a more sturdy bolt than the bolt in the kit. Is the shear strength of the stock bolt an issue? Where would you purchase one?

I have heard of several and witnessed one propeller bolt breaking. (luckily not mine) You should be able to pick one up at the Home Depot or Lowe's of your choice

The one I witnessed breaking was on a Terlingua, and not on the track when it broke.

I will upgrade the bolt. Any other mods that you recommend since I have just a stock suspension? Did you notice a difference after installing the watts link?

I would want to get rid of the hop that is inherent with the stock suspension. Easiest way to do this is at least an UCA but most do UCA and LCAs. I would definitely do this at the same time as the Watts. The other suspension pieces (springs, sway bars and shocks/struts) would be the next step after control arms and Watts in this case. Relocation brackets are for when you lower the car.

OK, I've never even heard of a Watts link. I've read a little bit about them now and kinda understand the purpose it serves. My impression is this is a true add on and not replacement type thing correct?

Sorry - don't make fun of the new guy .... :happy feet:

It replaces the panhard rod and brace. I moves the pivot point to the centerline rather than on on edge like the panhard, therefore keeping the rear axle better centered under the car. Also the instant center is adjustable by raising or lowering the pivot point in the center.

Get a grade 8 bolt to replace the grade 5 bolt used as the propeller bolt!

This is one of those times for me to chime in. During initial evaluation of the S197 F2WL, we determined that a grade 5 center pivot bolt would be the correct choice over a grade 8.

See http://www.fays2.net...s_link_12_.html

Particularly:
"We found the main PROPELLER BOLT had been bent approximately 2 degress from straight due to the lateral force exerted on the axle during the sideways slide through grass and dirt at high speed. I believe it is a testament to the strength of the components that a .75" diameter hardened bolt actually bent with no effect whatsoever on any other component. I'm not sure you should replace this bolt with an even higher grade, hardened bolt. This occurred due to very unusual circumstances that would be rarely encountered by the majority of users. Further, it's much less expensive, and easier, to replace a bolt than any other component."

We decided that under extreme situations the bolt is easier to replace than the entire frame. Now having said that, if any of you know a customer I can contact that did in fact break the grade 5 bolt please let me know so we can revisit our decision. I will say that in 6 years of having our setup on the market we have not heard of the center bolt breaking...including cars involved in accidents.

If you do decide to replace the center bolt with a grade 8 make sure you buy a 4.25 or 4.5 inch long bolt and cut it down like we do to insure you have sufficient shoulder length on the bolt for the propeller bearings to ride on.

One more issue. Some of you may have noticed that my return phone calls are taking a little extra time to happen (sometimes even a day later). Here's the reason: Through this May and then again this September through December I am taking some additional metallurgy and engineering classes along with some AutoCad and Catia software upgrades to tweak my product decisions and refinements. In the long run it should benefit all of you so thanks for your patience.

Thx for the info. I am in the process of obtaining the LCA and UCA from Steeda. The springs,struts, and sway bars will have to wait a few months though. Again, thx

Are you saying that you only need the relocation brackets if you want to lower the car, or when you lower the car? What additional parts/mods does lowering the car require? Right now the suspension on my Dad's GT500 is stock and we're looking to make the rear end more solid and stick to the road better under hard accelerating and cornering. We were originally looking at the Fays2 Watts Link and upper/lower CA's with the relocation brackets for each. Is this the best 1st step in the right direction or do we need to be thinking about more for the rear end?

Yes relocation brackets are used when you lower the car or for drag racing setup's. Lowering the car is done by using different (shorter) springs. Sounds like a great first step.
