I'm ready to dive into improving the handling of my car. I will be 90% street driven, but by no means a daily driver so I dont care about ride quality. It's all about performance
Here is what I have planned so far:

Once you're done: Align and corner balance.

If you want to keep the ride fairly "civilized" but improve the performance over stock pretty dramatically, the 19mm front swaybar and 140lb rear springs are a good combo.
Definitely lower the car and get a -good- alignment. Also of course the tire choice makes a HUGE difference. |

Back when my car was a street car, the two items with the biggest effect was a front sway bar and wheels/tires. I agree, the 19 mm and 140 lb springs with 205's will be like night and day.
You won't believe the difference over a stock car. Paul |

Does the front spring rate make that much of a difference? Everyone always seems to speak of the rears. I'll order the 19mm and 140lb rears. Thanks for the info guys. I only wish these damn riveria's would take something larger. This way I could keep the tires and swap when I do a 5 lug conversion w/fuchs, that is unless i get 16's. I can barely fit my pinky between the tire and fender. The offset seems all wrong.

I like a rear swaybar. I use them with 140 lb rear springs and they work great together. The front swaybar is a toss up. The bigger is a better choice for future use, but the ride is stiff. I'd also consider a weld in roll bar. Be sure to weld not bolt. The stiffness makes the car fun IMO.
You're doing the right thing- get lots of opinions and plan it the way that works for you. |

cavwpguy,
Sorry to disagree but you are the first person ever to say run a rear bar and the front bar is a toss up. Your car must oversteer like crazy. Mine did when I ran front and a rear bars and I took the rear bar out. And now I can't give the thing away. Front bar, no rear bar: no question. Paul |

I like big bars, Bilstein spo'ts, and rear bars.
I do like 'em! I really do! I don't remember what spring I like, but it's not the ones I have... (IMG:style_emoticons/default/blink.gif) M |

I actually ran a stock rear bar on my previous 914 (73 2.0) and found it pretty well balanced.
I had to pull the bar off my current car immediately, however, because I could not keep the inside rear tire on the ground. The main difference is a fairly tired stock 2.0 D-Jet engine, versus a significantly more powerful one and a significantly lightened and stiffened (caged) car. I plan to do a bit of testing with the rear bar again, once the LSD is installed. But with a handful of exceptions, virtually nobody I've talked to runs rear swaybars on these cars, even with LSD's. The general rule seems to be to keep the front suspension as stiiff as possible and leave the rear relatively soft. I still have some testing to do with rear springs too. |

Mine did when I ran front and a rear bars and I took the rear bar out. And now I can't give the thing away. Front bar, no rear bar: no question. Paul I should clarify. When I say the front bar is a toss up, I mean 19mm vs 22mm, not to be or not to be. The larger the better for performance but drivability becomes an issue. With the rear stock sway bar, I AX with it. Others in my class don't. I keep all four on the ground. Others don't. It's not all the rear swaybar, but I'm convinced it helps. If a person has one connected already, at least try it out. I heard often to get rid of it over and over, just like I heard that 19MM front sway bars were for AXs. (IMG:style_emoticons/default/ohmy.gif) I've heard that with a Q diff or 165 lb springs and up, disconnect it like you say. All this is just my experience so far. I also think a good roll bar cage, welded in, is worthwhile as well. |

Mine did when I ran front and a rear bars and I took the rear bar out. And now I can't give the thing away. You will quickly find that your 19mm is maxed out when you really start to drive the car. I ONLY recommend the 22 now. Its a waste of time buy the 19mm and end up with it set on full stiff 6 months after learning the car. Buy the 22mm and set it in the middle to start off. It will give you room to "adjust". Paul, I have been driving CaVW's car for 4-5 days now... it is ROCK solid with this setup (I installed it).. I'm going with larger sway bars in the front to compensate for lack of torsion bars (CaVW has stock bars) Once we install a larger torsion bars.. my adjustability range changes... so start off with a larger bar (more range of adjustment) We really like the cars to be a little softer sprung and run a big front bar and a rear bar. You wont see Rob's car lifting a tire..ever. B |

Oh.. I need some adjustable drop links for Rob's rear bar.. this would give me even more adjustability to the suspension setup.
