2-Wheel Alignment Tool - All-in-one (Camber/Caster/Toe Plates) - Made in USA

I did not get a chance to use the tool, but I am still going to rate the product 5 stars. Who knows, this product may perform well in real life application. I have a '23 GR86, lowered, unfortunately, the alignment tool does not fit under any of the tires. I have tried to come up with some way to use the tool, just could not make it to work, had to return. Perhaps a warning note on the product page to let potential buyers know that it may not work with lowered vehicles.

Here are some tips to help improve precision and accuracy when you use this system.1) find the center point on your wheel and align it with the center notch on the end plate. Then let the bottom of the plate rest on the ground and scoot it all the way against the tire before adjusting the studs that rest agains the edge of the wheel. Repeatability is the name of the game, however you set this thing up, you need to do it the same every time.2) Mark one tape measure front and one rear and put them in position. Get the average of the two measurements and divide that by 2. Mark this measurement on the bottom of the measuring tapes with a sharpie. You can use different colors for front/rear wheel track width or even different vehicles. Use these markings in conjunction with the centerline of the vehicle to help you dial in the toe adjustments.3) Mark the wheel locations on your workspace with tape or spray paint. Roll the vehicle off of that space and zero your camber on the line, ideally with a speed square or something and roll your vehicle back onto that marking before taking your measurement for that wheel. You could also use a precisely trimmed piece of cardboard or polycarbonate as a rotation plate.4) Roll the vehicle back and forth A yard or two a few times, while making sure to it add load to it as you push. This lets the suspension and tires settle into a normal operational position. It’s especially necessary after jacking up and lowering a vehicle down. Do this before you take any measurement, and do it every time.5) Get used to writing things down.This system will never be as good as a profession grade rack with lasers, but works well for me, as I am making adjustments based off of tire pyrometer and pressure readings in a competitive driving scenario. The actual number is not as important as achieving the desired handling characteristics in my use case.

A little pricey compared to some other ones ,but you usually get what you pay for. I am happy with this purchase

This is a good tool that does what it's supposed to. I believe that anyone who watches (and follows) the instructions will be able to measure their alignment. Making any alignment adjustments will obviously be on you though.The instructions are videos, with a dedicated one for each topic (assembly, camber, toe, and caster). They are are detailed step by step walkthroughs. You can also download and/or print out the written instructions if that's what you want.Caster must be measured by turning the front wheels specific amount (every alignment system requires this) and measuring the difference in camber to find caster. The required turn angle is built into the tool itself, so turn plates are not needed. It probably takes maybe a couple more minutes per side than using turn plates would, but since turn plates cost a couple hundred bucks the trade off is more than worth it. If you were going to be measuring caster on a very constant basis, then turn plates could probably be justified.Details: There are some nice details for this product, like the tape measure slots and degrees conversion chart. There are also rubber feet that go on the bottom of the plates to provide stability when measuring toe. The toe stand-offs attach with plastic screws, not metal ones. But as the company explains on their site, the screws are plastic so that if you accidentally drop or step on the tool, instead of the plates or stand-offs possibly being damaged, the easy to replace screw will take the force instead. They include 2 extras so if you do damage them you can just pop the extras in and keep going.Bottom line: this is a great all in one alignment tool. It functions as toe plates, a camber gauge, and turn plates, without needing those three separate tools. Camber measurement is not “hands-free”, but I personally do not miss that as you just hold it up and read the camber value, simple.
