914/6 torsion bar size recommendations
I’m building a 914/6 hot rod that will see HPDE use. Bilstein 911 struts, elephant poly bronze bushings and Weltmeister 19 front sway bar. 205 tires, narrow body, 3.0 911sc motor.
Will run at Sebring which is rough. How big should I go on front torsion bars. Last edited by Maj75; 02-12-2021 at 03:00 PM.. |

I'm running that combo on stock torsion bars with a 21mm tarrett hollow swaybar.
I don't know if I'd want stiffer even for AX and at that point I'd worry about stiffening the chassis first.

The chassis will have all the chassis stiffeners currently available, inner longs, trailing arms, engine compartment and sway bar without going to a cage/tube braces.

I think 21mm is good for some auto-x and track days.
If you're more of a daily driver, then go down to 20mm or even 19mm.

i think there's almost no resources for 914 tortion bars. please someone chime in if i'm mistaken.
almost everything i found was for 911's, hence another reason to switch over to 5 lug. [MODERATOR EDIT -- spammy commercial link removed] |

Most places that make 911 torsion bars can also make them with 914 splines on the ends.
Sway-A-Way, for instance, has options from 17mm through 23mm. Pelican, your hosts here, carry them ... and I have removed the link you posted, since it is not 914 related in any way. --DD

Also Elephant Racing would carry the "914" torsion bars.
But if Pelican Parts has them....why not try there 1st.

I spent some time this week updating all the Sway-A-Way Torsion bars, definitely a great cost effective modification to really change how your car handles. Available in hollow or solid steel, only main difference being weight (about 1.2lbs per bar).
