Hotchkis Sway Bars
« on: January 14, 2019, 04:08:27 am »
Hello all,

I am currently in looking for sway bars for my 1970 B2. Has anyone used these on their boss?:

https://www.hotchkis.net/product/1967-1970-mustang-sway-bar-set-from-hotchkis-sport-suspension/?mk=54&yr=1970&md=688&sm=1138

I realise the bars are bigger than standard size (1 1/4 inch front and 7/8 rear)...how much would the spring rates be affected by the bigger diameter?

Donald Farr's book mentions 350lbs front and 150lbs rear as stock spring rates...Hotchkis as part of another package with their sway bars use 700lbs on the front and 180lbs on the rear.

Haven't brought springs or sway bars yet, trying to find good balance between them..

Curious to know what combinations of sway bars/springs people are using on the their Bosses  :)

Thanks for your help, appreciated.

I can not comment on the Hotchkis brand or quality of their products. However, a buddy installed Addco (correct sp?), and as a result the rear bar frame attachment tore/broke his frame from use. That said, he is not a racer, so I assume it was the result of bad engineering/design on Addco's part. Be careful, and only buy from known brands that actually work and will not damage your car.

Crossboss, do you know if your friend's Addco bar was larger than stock?

Thank you for the info Crossboss, as a matter of interest do you have any idea what spring rates you’re running on your boss?

My old car was a T/A Boss, best front spring rates were 675, rears were 200. I used Global West's 'Negative Roll' suspension from way back in the 1980s. Btw, I had no rear bar…was not needed. When I did, it caused massive understeer issues. Remember, this was my set up, and most likely is not what your car will need or work for you.

Stick with the Ford engineered set up.  Won't hurt.  The 70 factory spec probably better balance than the 69 (more push).

Unless the mfg has done real time analysis and physical testing (skid pad testing),  I would steer clear.

Check Aldrich Motor Sports.  Did not see on his web page tonight,  but I think he does the 70 BOSS 302 front and rear set up.
