Installed J&M camber plates

[AlbertD]

I've had the J&M camber plates for the past 30k miles, no issues. They aren't bad. Was very easy to adjust my alignment as well. Sitting on sportlines up front and bmrs out back

Youd hear a clunking sound coming fromt the front.

Good to know. No clunking here.

I got the J&Ms to with Steeda sports, wasn't aware of the warranty but good to know. No issues so far.

My J&M plates arrived with bad bearings.

My J&M plates arrived with bad bearings.

WTF...

I hope mine don't arrive that way.

-1° is a mild performance number, but since it's a little more aggressive than Ford's OE setting for most Mustangs (-0.75°, though I think a couple actually do call for -1°), it's a little outside what most shops are expecting to hear from a random customer (essentially, you're disagreeing with their machine's database). Even though what you're asking for is well within Ford's max-negative number (-1.5°). They may even not be familiar with camber plates, as that is not an OE adjustment technique.

When I ran into a similar situation many years ago, I decided that from that point onward I was going to do my own alignments. Haven't had a car on an honest-to-god alignment rack in over 35 years. There's a few things to be aware of with respect to making the measurements, but other than that it's mostly just patience and turning wrenches.

Your tires are suffering only if most of the time you're a mild-mannered driver in the corners and/or do a huge amount of highway driving.


06vista - it sounds like you've been fortunate enough to have found a shop that understands what they're doing a little deeper than just putting the machine's indicators in the green or spot-on to the OE preferred values. Should you decide at some time to run a more aggressive setup and the place has the same crew working there, I wouldn't expect them to object to making a setting at least up to Ford's max negative.

Thanks Norm… I told the shop I changed the springs all around and the shocks and struts. I mentioned to them what I've read here w/ other members and the camber #'s … they still tell me I'm fine where is at now. Do I install the J&M's and head for another shop?

It sounds like they're unwilling to trust your own evaluation of your own driving to be slightly more aggressive through the corners than some unknown "average driver".

I can't say as I blame them for not trusting "internet wisdom" if they aren't going to bother going through the thought process for why it might actually be right. Then again, when what you do in your day job is put the indicators in the green, there isn't much call to understand the why of it all (or even remember it assuming that this kind of background information was presented in a training session for the equipment).

They're looking at you odd because -0.75° is what Ford has defined to be "fine" for the average driver. And as far as they're concerned, everybody is "average".

If you're more enthusiastic through the corners than the average driver or the average person who might have been expected to buy a Mustang, it won't be enough.

On the other hand, if you're a very mild-mannered driver, -0.75° might even be too much.


FWIW, somebody I know pretty well used to work in various shops. Near as I can tell, he was pretty good at getting lots of different jobs done, including alignment. But you can't tell him that anything other than OE spec or OE setting is any good. Forget about teaching him why and under what conditions it might be.


Yeah, you probably should inquire elsewhere. Either that or buy a digital angle finder, find a flat place to set up on to do the cambers yourself, and maybe let the first shop do the toe only with instructions to not touch anything except the toe.
