Hey guys,
So I have a 74' standard beetle that sits at stock height with stock springs/torsion bars, dual 3/4" sway bars, and KYB soft ride shocks on 165/80R15 tires. I was wondering what kind of alignment specs you guys like for a road car (have some more fun windy roads on my way to work, but lots of freeway too). Here is kind of what I was thinking, but im not sure.
Front:
1-1.5 deg neg camber
1-2mm toe out
Rear:
1-1.5 deg neg camber (probably matched to the front)
1-2mm toe in _________________ '74 - front disks/lots more work to do |

Do you want your tires to wear abnormally? _________________ My beetle is not competing with your beetle. I have the yellow beetle in my town. There is a red one, a green one ......

are you talking about the one sided wear from the camber or the increased wear from the toe? I was under the impression that such minor adjustments shouldnt cause significanty increased or weird wear. _________________ '74 - front disks/lots more work to do |

Did you mix up the toe specs? I believe it should be toe in on the front and toe out on the rear. |

Went to alignment recently and after getting it right, I consider it, especially for a bug extremely important to get right. Besides power, handling is what makes the fun and safe to drive.
Unless you have a shop that will is really willing to test drive it after alignment more then once you really never know.
My bug has dropped front spindles 2 1/2" drop, Plus 195 60 15 rears and 195 50 15 race tires front. Same KYB as you in the front and Gas A Just KYB in the rear. Front and rear anti sway bars.
Car had a life of it's own, dart from here to there, dangerous.
I put in New Ball joints, tie rods and tie rod ends. Now comes the story.
I got several suggestions as to how to have it aligned.
One was use two sets of spacers to correct camber.
I go to check out the car the mechanic and see the two sets on the car.
I get a call, car is ready, get on the NYS Thruway in one direction and do 90 no problem, then on the way back 100 and the steering got light.
Went back tell the shop -- great job.. Look under the car and do not see the two sets of shims which were on the car before.
The Machanic says, we tried one set did not like it, then tried the other did not like it either. Took them out realigned. He test drove it at 80 each time till he felt it right.
My point when you do what we think is a simple mod like a tire size.
You need a good shop to take their time and get it right. _________________ email: [email protected]

CASTER shims, not camber shims.
Caster is the angle of the steering axis of your spindles, and more caster = greater self-centering tendency of the steering...this will make the steering feel more stable at high speeds and when braking (when the dive of the front end naturally decreases the caster angle). _________________

Uh, no...the eccentrics on the top of the spindle do not change the caster angle _________________

Yes they do. Because they rotate they not only move the top mount o fthe spindle left and right relative to the upper balljoint, but forward and backwards as well causing minor changes in castor. _________________ '74 - front disks/lots more work to do |

No, they don't. The caster is determined solely by the position of the ball joints. The steering axis cannot rotate through any points except the center of the upper ball joint and the center of the lower ball joint.
If you had some magical eccentric that could shift the steering knuckle 45 degrees, the axis of steering would still pass through the upper and lower ball joint, which have not changed their position.
The eccentric does shift the position of the spindle (the center of the axle) with respect to the steering axis, but that has a minor effect on trail, not on the caster angle itself. _________________

I think I understand what yo're getting at, but don't forget, the eccentric does change the relation of the axis of the wheel's rotation to the axis which goes through both all joints.
Wheel offset also has big influence on handling... |

That would be the "trail", which I described above (this is more appropriately defined as the distance between the tire's point of contact at the ground and the projection of the steering axis to the ground). The eccentric affects the trail by approximately 1/2 the fore/aft distance created by changing the position of the eccentric. Changing the caster angle via caster shims has a larger effect on trail than the eccentric does. _________________

I think you are forgetting that ball joint pivot. you would be correct if the ball join was a solid piece, but when you adjust the eccentric the ball joint also adjusts slightly into a different position. This adjustment of the balljoint between the forward and the rear of the car (because the spindle is a solid piece) absolutely requires the adjustment of the balljoint to move at all, there by effecting caster. _________________ '74 - front disks/lots more work to do |

Ok, so I ended up dropping it off at the shop yesterday and asked the guy there what he recommended (shop had a GL bug out front and lots of buses and ghias so I figured I would ask). They basically said, for street use, a good compromise is anywhere between -0.5 to -1 deg camber and then straight ahead of rear and about 1/2mm roe put in front so that you still get the extra bite but don’t sweep the tires all too bad. I’ll go ahead and report back with exactly what they did and how it feels when I get it back tomorrow _________________ '74 - front disks/lots more work to do |
