Title: TC Front Anti-Roll Bar specs
Post by: cazman on Sunday,January 30, 2022, 04:47:55 AM

Does anyone have the dimensions for the front anti-roll bar on a TCS?

I cannot find the diameter, length, arm length, etc anywhere.

I have an S2 and TC bar on the shelf. The overall dimensions are the same except diameter.

S2 .570"
TC .700"
+/- some for paint.

I used this calculator to figure out what the factory rates were before making an adjustable 7/8" one.

What Turboforce did is probably the best way to get a little stiffer and to have it adjustable. Many old Formula Fords did the same.

Thanks.  I show about 180lb spring rate for the front bar.

I wrote down 137 lbs on the TC bar, 180 lbs on the aftermarket .750.  247/323/414 on my 7/8". It's been a while so I don't know what I used for my input on the stock bars.

I think Serge calculated it on his anti-roll bar video. Seems it was close to your number Clifton.

I had to crawl under the nose and take some measurements and I think the 137 lbs is probably right.
