Hi folks, hoping to get some thoughts on what torsion bar size people with 911 front suspension are running for road/touring cars? My current set up is too firm for comfortable use and to minimize down time I would like to have the replacement bars on hand.
I have not pulled the existing bars out but it's the bars, not the shocks, since I have new Koni shocks on the front that aren't harsh. Thanks! |

I don't remember the stock 911 size but i think it's already bigger than a stock 914 bar. I prefer a bigger sway bar over bigger torsion bars for anything mostly street driven.

I'm running the 18.8mm 911 torsion bars, they are one mm bigger (17.8) than 914-4 torsion bars. The very early 911's did run 17.8, the same as a stock 914-4. I had a set and traded it to Bruce for the later 18.8 |

(IMG:style_emoticons/default/smilie_pokal.gif) You use springs (or torsion bars) to support the weight of the vehicle and to absorb vertical inputs. Body roll is controlled via Anti-Roll Bar. |

A lot of people think bigger is better but torsion bar spring rate ramps up quickly and too big makes the car very uncomfortable. |

Everybody is different! I prefer spring rate over bar!

Spring rate provides degrees of ride firmness.
Sway bars, since they connect the opposing corner, provide degrees of ride harshness. And there are shocks that can do both. Balance is the key. Sherwood |
