Finally got the 5 lug swap sorted out with new turbo tie-rods, M calipers, wheel bearings, brake pads, alignment, etc.
Alignment came out at 1.00 front camber, 1.5 rear camber and 1/16th toe-in front and rear. (Guy said that's as close as he could get to what I wanted) Took the car out for a spin earlier and man it's like everything is tied into a light switch. The slightest input to the steering wheel and it wants to change directions RIGHT NOW!!! Also seems to pick up every contour in the road surface which was kinda unnerveing over 60. Are these the changes I should expect? I'm gonna have to learn to drive it all over again... (IMG:style_emoticons/default/driving.gif) |

Yes Allan that is how it should be. No "spongeyness" like on a power-steering car or a 914 with rubber tie rod ends (IMG:style_emoticons/default/biggrin.gif)

where'd you get it aligned? how much caster?
do a quick toe check, make sure you've really got toe in (not out). my car is also a little "twichy" (0 toe front, 1/8" in rear), but not unnerving, even at 110+. if the car is simply too sensative, then take it back and try a little more toe in.. |

There is no "perfect" alignment for everyone. If it's too twitchy for you, it's not well set up for you. I would double check that you have what you asked for, then drive the car for awhile to see if you can get used to it. If you decide you don't like it, then keep tweaking.
Following road undulations may be a bump steer problem. Is the car lowered? Are there any spacers under the rack? |

The car is not severely low like say Trekkors is, and I do have a bump steer kit installed. I think It's just going to take some time to get use to. I'll drive it for a while and if things (being me) don't adapt I'll take it to a teener guy I know. Also, would the tire pressure affect this? Too much make it skittish? I just went out and checked and I'm currently running 36 lbs. all the way around. |

I just went out and checked and I'm currently running 36 lbs. all the way around. 36PSI?! THAT IS WAY TOO HIGH!! Even with 195/60-15's, you should be running about 24-25 PSI; that's what I run with 205/60-15's all around. No wonder you're dartin' about, loosening your fillings, and feeling every roach & pebble out there. |

Jeez, mostly I see 28 - 32 around here. 24 - 25 seems like the pressure I use to let my truck tires down to when I was at the beach. Are you sure? |

32-35 psi on a street tire is the norm.
When I went to turbo tie rods, bump kit and a comp alignment I was thrilled with the turn-in response. Yes it is "new". You'll get used to it. It's great. KT |

KT Thanks Trek. I'm gonna drop my pressure to about 32 -33 lbs. and see what happens. I'm sure alot of it is me. When I was at Lonepine I let Aaron drive it and he commented that it was sluggish in steering response. I just have to remember that I am use to driving teeners with only original steering components. I'm now starting to think that I may drive it to Santa Barbara Saturday. P.S., I do have AAA....

Unfortunately, no. I'm gonna take the car over to Mike Zois place and see how well we can tune it after an MSD/Crane ignition swap. I wish more of you guys could make the Buttonwillow event(s). I'm kind of lucky that I'm in between the lot of you evil doers. Now that the house is off the market I'm gonna try and make some of the Nor Cal events. So get ready to see the back of my car.....

When I first started driving my 914, I had to be REALLY careful not to accidently change lanes every time I saw something interesting on the side of the road. As soon as my head turned, the whole car followed. I love it now, I'm constantly playing dodge the potholes to keep the ride smooth and the alignment correct. I can slalom a pothole at 70 mph and still be glued to the road, its fun (IMG:style_emoticons/default/biggrin.gif)

If you read the sticker on the car for tire pressures, it's 26 front, 29 rear with stock tires.
At Willow Springs on "whitey", I was running 23 / 25. But then, that's just me. |

Yep, I just don't see why such high pressures are being used, when OEM pressures are in the 25-27 PSI range anyway. 25 PSI and the tires wear evenly, doesn't cause the car to be twichy, nervous, and no unusual antics. Do whatcha want, but your issues ARE PSI-rated. |

Pressures are going to vary a lot from tire to tire, and how the car is driven. The factory pressures were for 165/80 tires using 1960s era tire technology. This is going to have very little relation to what you run using 195/60s using 2000s era tire technology, or 205/50 sticky "street" tires that would outperform the very best race tires available in the 1960s, when 50-series tires were completely unheard of.
If 25 psi works for you, with your car, how you drive it, great. It's not going to work for everyone. |

I have to agree, that's too high. The "yeah, 32 lbs all around" came from the times of bias ply tires and service station attendants. Car and tire manufacturer's recommendations are usually 28 lbs or lower. That's a compromise pressure for ride/tire wear/handling/noise, and it's a reasonably good level for the street. So start there and adjust to whatever suits you.

Hrmm, I'm running the Falken 615s at 36/38, and that's lower than recommended by some!
Rouser, I don't see how you say that 36 PSI is too high when you don't know what tire he's running. Anything under 30 lbs on the tires I've used over the years has always felt sloppy to me. But again, that's with the tires I had installed. The darting/twitchy steering sounds like a toe-problem to me. |
