SPC Performance FasTrax Camber/Caster Gauge (for 13-17in. Wheels)

I also bought a Toe adapter kit as well, and works great for my 65' Chevelle project. You need get use to it by doing couple time. Once you get it, you'll start check an car alignment around you w/o ask from nobody lol. Nice quality easy to use, I can definitely recommend anybody!

Seems like a pretty basic tool. Poorly shipped missing screws. Works very well.

01 Crown Vic I replaced the whole front end, joints, rods, arm bushings and springs. Took it to the shop for an alignment and they said you’re in the green we didn’t charge u for it because we didn’t adjust anything. I could not keep the car in a lane and have been through this before with shops not being able to dial in my vehicles so I bought this Fastrax tool along with turning plates. This tool Is simple to use and accurate, so happy with this purchase- I found the drivers caster out 1 degree and the passenger was 2 out- the car is very stable now and I am a smiling man.

I rebuilt the front end on my 1965 Mustang and needed to align the tires. I've never attempted to do a front end alignment and wanted to learn the basics of camber, caster and toe-in. I read as much as I could find and finally decided to give it a try (If I get into trouble I can always go to the alignment shop). I bought the 91000 unit. After the front end rebuild, the car pulled hard to one side and struggle to get around corners. After leveling the 91000 and affixing to the wheel, I found the camber to be reasonably close to spec. The caster though was way off. It only took me about 45-minutes to adjust the caster and re-check the setting using the tool. On the test drive and the car is tracks straight and I've eliminated the pull to one side. Easy to get around corners. Just a few degrees of caster angle changed the entire drive experience. SO glad I took the initiative to purchase this unit. Super easy to use and I can check and perform my own alignments. Doing it myself saved me half a day sitting at the alignment shop and a bill of $100. This tool will be paying for itself on my next alignment and I learned the basics of front end geometry.

Doesn’t cling to my American racing wheels as well as I wish and the bubble is off 1/4 degree total but you can compensate for that. I had to adjust the guide screws and tighten the pins, again no problem. I’m quite happy with it and recommend it. Use it a couple times and you’re an expert!

The idea of doing alignment yourself is awesome and pays out second time you use this tool. Can't complain about quality, built to last. However, this kit suffers utterly from bubble level: it is hard to set zero level, and overall precision is inadequate for this kind of work. My car needs -0.3 for camber, and if one side is only 0.1 off the car slightly pulls to side. I'd say, bubble level precision is no better than 0.5 degree, so mission was impossible, until, as was suggested in other review, I went to Home Depot and bought cheap thirty-something bucks digital torpedo level. With digital level I could adjust camber with 0.1 degree precision, and set it exactly at spec - you hardly get it at shop!

This little device was something I was missing in my alignment arsenal for quite a while, and it works perfectly, saving me $90 a crack on alignments that need to be done almost every time you change or adjust anything on a front wheel drive car. Set it to zero and set it on your car, which also has to be on a level surface. All three cars I have done so far are fantastic. Always remember to set the camber before the toe and you won't miss. I rate this tool extra high because of the aggravation and frustration it has saved me from.

I bought this to confirm alignment values on my F150 after I did a short drop kit (2" front, 4" rear). After the drop I could visually see the negative camber on the front wheels. I measured them with this FasTrax, which said I was at negative 2.7 degrees. Just for fun I measured the same thing using a straight edge piece of aluminum on the outer ridge of the wheel and an Angle Finder app on my Samsung S21. The S21 measured 1.2 degrees. Next I put both on the level surface of my Bridgeport mill and yes, the Fastrax was showing more angle than the S21. I tried the same thing with two different phones over two different angle finding apps and the Fastrax was confirmed to be not accurate even though there's a "factory set" screw on the bottom supposedly locking down perfectly level. Fortunately it's adjustable, and now it's actually level. I also tried measuring caster. Following the instructions (and instructional videos online) I went thru the motions exactly as instructed and my caster was apparently over 6 degrees. The factory spec is 3.75 degrees. I did everything I could do to the control arms to try getting it down to 3.75 degrees using the Fastrax to measure and eventually gave up and took the truck to an alignment shop. After they adjusted and confirmed 3.75 degrees I tried the Fastrax again and sure enough, over 6 degrees of caster!!!!! I don't know if someone painted the numbers on wrong or what the deal is but this thing isn't worth the antifreeze in the level.

It appears to be high quality, will use it soon.

I use this to align the wheels on my 69 Mercury Cougar. Does an excellent job. Highly recommended.

The only thing i didnt like is the pins that go onto the rim, they slip quite easily . They come with little rubber bits that still dont bite onto the rim. Have seen a serrated or thread style pin that locks on to the rim much better.

great unit nice easy to use got on utube for video to use it love it for my 66 mustang
