On checking out how all the commercial gauges work, I also discovered several accuracy problems that I wanted to overcome with a new system, I’m glad to say I solved them all.
Well now all the reviews are great, but with something new most of us take reviews with a pinch of salt and usually head off to search forums for opinions and reassurance before we part with our hard earned cash, after all how often does something suddently appear that really does the job for a fraction of the price. I did think the Trackace innovations were fairly obvious, but it seems not, there’s lots of misleading assumptions and myths out there about front wheel alignment and about the Trackace system itself, even by some forum “Experts”, so it’s time for this simple little kit to flex its innovative muscle.
Trackace is the most reliably accurate laser wheel alignment gauge available.
Trackace is a total toe angle gauge, all systems retailing up to around £1000 are total toe angle gauges. Adjusting tracking is the same principle with Trackace as with these gauges.
You do not have to refer to the rear wheels to set front toe properly, it should be set central with the steering gear. If we were talking rear wheels then yes, you must set up with the front wheels, a rear wheel add-on kit from Trackace is in the pipeline at no more cost than the front wheel kit, all with the same simple logical approach to accuracy. Once available the add-on kit approach will offer most flexibility, for example, if your vehicle does not have adjustable rear wheels (many don't) you can opt for the front wheel only kit but retain the option to add the rear wheel kit should you change to a vehicle with adjustable rear wheels in the future.
You do not have to contact half way up the wheels when measuring in degrees, unlike when measuring directly in mm's, but you do have to reference against a level plane through each wheel.
Go over £1000 you can get gauges that do refer to the rear wheels, this is to assist getting the steering central more quickly in a commercial environment where time is money, but you can centre the steering without any gauges at all.
Spend even more, you could go for a system that uses two lasers and two simple scales, again assists centring the steering, but the problem here is simple scales cannot be accurate for different sized vehicles.
Everything is only as accurate as its calibration. Trackace is the only gauge that is calibrated at a much greater distance than its operating distance and automatically calibrated to this high standard at every use because it is an integral part of the checking procedure.
To make it as clear as possible, a picture says a thousand words.
