Does anyone have a photo of the correct set-up for caster on a 84-87 fiero??
I need the settings on what thickness of washers to install for the alignment to be correct.
A detailed pic would help, and the amount of mm it has to be. If Irecall, it can't be more than 12mm or 9mm??

BTW, do alignment shops know where to put them???

Sorry, but I did a search with no success.

Thanks,

every car is different, to get a proper alignment you need an alignment machine or some oldschool alignment equipment.

alignment shops will know how to properly align the car. you need to make sure if your getting the cheapest alignment they arnt just adjusting toe.

you can probably get it close by asking that question but it wont be perfect.

Thanks, but I would like for reference what is the stock set-up for these years. (84-87)
example: how many mm of in front and how many mm at the rear of the upper control arm.

Thanks,

Sorry, I don't have the factory service manual as a help.

According to the info at this site, the spacers are a "matched pair of serrated washers with a constant total thickness" (doesn’t say what the thickness is). Replacement “thick and thin” washers can be purchased from the dealer to change the caster 1° either direction. "Increasing the thickness at the front will reduce caster and increasing thickness at the rear will increase caster."

Don’t know if any of this is correct but there are pictures showing the adjustment points.

Technically, I just want the factory set-up specs for those caster washers, that's all. How many mm at the front on the control arm and how many at the rear.

Thanks,

I was just about to scan and print the 4 page 1986 factory service manual section on full 4 wheel alignment anyway! It should apply to ALL pre-88 models. If you give me a little time, I'll post it. Unless someone has concerns about legal issues... but I say #$*& that.

Edit: Ok, here's the full procedure for yourself or whatever shop you go to, including specs: https://www.fiero.nl/forum/Forum2/HTML/083611.html

West Coast Fiero charged me $100 for an alignment on my car using bars, sticks and twine and my tires were worn out in 6000 miles. That's my experience with "old school" alignments, I guess.

From what I've seen in threads on alignment, alignments are a common thing where people get 'taken" all the time. Be sure you get a computer printout and that the numbers are within the specs and DO NOT accept explainations to the contrary. I've heard " don't worry about it - the number can be Out-Of-Spec as long as the number is the same for both wheels." Baloney - that's just a lazy tech who wants paid without taking the time to properly adjust the suspension !

Here's my old alignment from a 20th century shop with the "it's OK as long as both sides are the same" excuse. See that the castor is out of spec but the same for both front wheels :



Here's the printout after they did another alignment today. To get the castor in spec., they had to re-adjust the spacer/ washers on the upper control arms - in this case, both 6 mm spacers (total 12 mm) are in the rear of the control arm. After moving the spacer / washers they had to do another 4 wheel alignment, which was work they originally wanted Not to do :



Since I have all 12 mm in the rear of the control arm, i guess that's all the castor I'm gonna get (unless I change the bushings ?)
