Depends on what you want. You could use the factory arms to set the lengths good enough to get it to an alignment shop. Or you could set up with plum bobs and masking tape on a level surface and get everything pretty damn close. My suggestion is getting it close with the stock stuff and get it to someone reputable to get everything on point.

Hopefully that's not what your doing seeing how a lot fly's this way......lol . The reason why I was asking if they are aftermarket A arms is UMI Performance presets there's to stock settings giving the customer a good baseline to begin with. IF they were or are UMI A Arms I would be glad to help the customer get them set back to factory settings. If you have any other questions feel free to ask and I will be glad to help!
Thanks Again,
Brad

When I installed my front lower A arms (neither BMR or UMI) I tried to take some measurements and set them close to the stock arms. When it went back on the ground the alignment was way off in so many ways. I adjusted it to get it driveable (mainly toe adjustments) then had a shop align it to the specs I wanted.

I cant imagine how much of a headache it would have been if I had done upper and lower at the same time. My guess would be that having them set to stock specs would help but it will probaly still need finishing touches by someone with and alignment rack.

I have PA racing arms. I need to guess at them but the hemi's are loose. So they are not really set to any length.

If anything the worst thing is your toe. Bolt the rotor to the hub without the wheel on it. Then take a straight edge (steel stock, long ruler) and clamp it to the rotor face on the bottom. Then if you dont have a straight measurement you can get with a tape measure, hang a piece of string off both ends with a nut or bolt on the end and measure that way.Measure in the front and back and get the two measurements as close as possible and that should get you good to the alignment shop. If the camber looks off just put a bolt on a piece of string and hang it off the top of the fender. Measure the tire at the top and bottom and get those measurements as close to the same a s possible.
