Datsun Competition's S30 Sway Bar Advice

[Zzeal]

This is from a late '70's Datsun Competition Parts catalog:

 

Stabilizer Bars

 

"The 19mm rear stabilizer bar should be adapted to Z cars that retain the stock front stabilizer bar (17mm) and did not come standard with any stabilizer bar on the rear.

 

The 22mm front stabilizer bar and the 23mm rear bar should be used together for all around high performance driving and when installing the factory race or rally suspension kits.

 

The 25mm rear stabilizer bar is designed to be used in applications where a lot of oversteer is desired, such as slaloms or autocross."

 

 

Now, a typical set-up is a 1" front and 3/4" rear. How'd we get so far away from Datsun Competition's recommendation?

30 years of testing? or having a compromise between street and track.

Better shocks, stockier tires. Also, a "typical" race setup isn't the 1" front and 3/4" rear bar. That's a normal baseline to get started but most race setups evolve from that based on testing and driver preference. Anything from 28mm front and no rear bar to 19mm front and 13mm rear bars. I rarely (if ever) see a rear bar greater then 19mm on a race S30.
