My left front wheel had noticeable + camber. I made a calculation that the ane degree of camber (or castor) is egual to about .45 inch every bit measured and shown in the shop manual. So this way I tin convert degrees to inches, I can measure inches easier than degrees. The manufactory store manual says the Camber Spec is (positive) 1/2 degree, +/- 1/2 degree. I measured and calculated my camber with the set-up shown, that wheel was positive 1/2 caste. Within spec, only it doesn't expect to good to the centre. I wanted about 0 degrees of camber. I purchased shims at at the motorcar parts shop and again figured about a 3/sixteen" shim. Put the shims in and it is now measuring 0 degrees camber, merely what I wanted. By the way, maybe I can get a picayune more than, even a lilliputian negative on the camber, will this make the automobile corner fifty-fifty better? At present a Question on castor: Most people say get as much Positive as you can. And then I can but add another say 1/8" shim to the front side of the A arm and go more brush? Practice I have to do both drivers and passenger sides equally? How practice DIY'er measure this anyhow? Or practice I have to measure information technology at all? Finally, how thick can the shim pack get and yet be rubber? My rider side already has most three/8" or so total. 1957 Belair 2Dr Hdtp, 58,000 original miles, original never rebuilt 283 engine, 245hp, Dual Fours, Tremec TKO 600 5-speed, 3.70 gears, AACA Senior in 1985 |

Y'all are backwards on how to accommodate for positive caster. You should increment positive castor past decreasing the number of shims on the front and/or increase the number of shims on the rear bolt. So you end upwardly with more than rear shim thickness than front.

Why the heck are you even farting with something like this yourself when a front end shop will align your front properly for about $sixty.00. Judging past the looks of your car surely you can afford the $60. And it ain't similar you live in bum puck egypt where at that place aren't any front cease shops. Please don't take this the wrong way, only I other then looking for something to do for giggles, I don't get it. No offense and no insults intended. |

If you desire to get fancy replace the carpenters level with a level that reads digitally in degrees. Smart level makes an inexpensive production. Make sure your block of wood is exactly the same thickness top to bottom and the screws bolts are identical length in from the face of the level. Make sure the floor is level FIRST....otherwise your readings will err. Longacre (and others) have magnetic caster/camber chimera readout gages that are under $100. The toll keeps falling.

""""""""Nigh people say get every bit much Positive as yous can.""""""" Truthful...upward to about three* or with super wide tires mayb 4*.

That is to say if your chassis is EXACTLY square and every dimension is .000" +.000" -.000" simply and so what you do to one side you can do to the other.

On 55-57's doing this shouldn't change toe-in enough to worry most it. |

To get the caster you desire you have to move the top ball articulation to the rear. right now I'k non certain if you put shims in or have them out just merely motility the ball articulation to the rear for more than caster |
| Rick_L Fellow member #409 Posts: 27955 Loc: Katy, Tx, USA Reg: 07-06-00 User Info Send Private Topic | Re: Home forepart end alignment 101! Movie! 08-05-05 02:51 PM - Post#754201 In response to 2DrPostPhil Phil, on the 55-57 forepart the shaft is on the within of the frame mount and y'all take shims off the front end and add them to the rear to move the ball articulation back. As Chevynut showed in his photograph the C4 Corvette (and others) have the shaft outside the frame mount and you add shims at the forepart and remove them at the rear to move the brawl joint back and go more positive caster. The camber aligning is as well reversed on that type. 1 of the archetype problems with 55-57 cars is that you frequently run out of shims earlier you lot can get the caster adjustment y'all want, since you have to remove them. This is due to the manner they made the crossmember and sometimes they sag making it worse. On the Vette style if the crossmember sags you add more shims, and so this is not nearly the problem. No problem, it's easy to go it backwards, and the fact that some are one way and others the other is disruptive. |

I am assumming that this will requite me better steering wheel "return" and ameliorate high speed tracking, simply steering may get a picayune harder.

They are not the manufacturer of the digital level (Smart Tool), but use it in their product. Hither is a link to another identify that sells the "Smart Tool". http://www.speedpartz.com/smarttool.htm What I did was build a device that uses a "Smart Tool" but like the Smart Racing unit of measurement. In fact, physically, it's in between CJS57's deal with a level and the more sophisticated Smart Racing guess. The deal I built is used only similar outlined in the Smart Racing manual, which is on their website. Your thoughts on the toe in measurement will work quite well. Recollect that the toe in spec in the shop manual is total for both front tires. So if you measure information technology relative to a line parallel to the auto's length, the spec is half that (since it's for one wheel). |

Yous'll observe that unless its a very good laser tool you volition accept besides broad a line shooting the wheelbase of a vehicle and also the line gets a little ragged later on almost six feet or then. Iv jackstands forming a rectangle around the machine with fishing line pulled taut front end to rear each side and use a digital or dial caliper from the string in to the rim edge. You lot volition then run across if the front end is foursquare with the rear as you set the cord (southward) on each side exactly parallel with the rear rims....(use 9 and three o'clock on the rims).... this assumes the rear stop housing is not bent. |

. Positive caster means the upper balljoint is BEHIND the lower balljoint to slant the spindle back at the top. That takes more than shims in the front of the a-arm than the back.
