BTW, the folks at Longacre are friendly and helpful...you can give them a call.

Someone on another forum was selling a product a few years ago that I bought that was essentially this: http://www.intercompracing.com/digit...p-99-l-en.html with an adjustable mount to line up with the wheel, and also turn plates. I used it for several years on my last race car and it was great, very easy to use. That car also had camber plates, so adjustments were easy.

I used the one listed in the first post. I aligned it at home, and then took it to honda and had them go through it on a Hunter laser rack. I got caster almost right on, and the camber showed less by about .2 degrees all the way around(on the hunter rack).


The minimum rear camber I could get with the longacre gauge was -2.2 degrees each side. The hunter rack came out as -1.9 each side. The front was set with the longacre at -1.5 degrees, and the hunter showed it at -1.4 degrees.

To me that is pretty close (maybe not the 2.2 to 1.9, but the fronts were close). I made blocks for my car to sit on, so I could make adjustments under the car. I also used plastic bags under the wheels so they could move around under weight.

I made a cheap turntable for caster out of a piece of aluminum and a vinyl tile. I drew a circle on the tile, did some math, and drew out my angles. With a plastic bag under the other front wheel, I was able to turn the wheel (not the steering wheel) by hand. This made it so much easier to measure caster as I could turn 15degrees, measure camber, then turn the wheel to opposite 15degrees.

I'd like to get rid of the vinyl tile and replace it with another piece of aluminum to make it more durable though. Mcmaster also sells cheap turntables that would probably also work, some are rated at 1000lbs. Mine worked out well...didn't slip between tire and aluminum plate. Used some lubricant between the aluminum and the tile. I would say it comes out pretty close. Toe was more of a pain for me to set.

I got the gauge in and while I haven't done any alignments yet, I did try it on my S2000 and TT-RS. The S2000 is way off and the TT-RS is in pretty good shape. Interestingly, the Longacre shows a bit less camber than the latest alignment sheet I have on the TT-RS. The Hunter machine showed -1.3 both front sides, the Longacre -1.1 both front sides. The alignment was done last summer so it could have moved, but if it did, it moved equally on both front wheels.

It is not a hands free tool, you do have to hold it against the rim. The standoffs have a lip that can go around the outside of the rim to help steady it if there is room, there was on the TT-RS, not on the AP1 V1 Rims with RS3 tires. I've ordered a second set of standoffs, the same ones that come with the smaller model, so I can use what's best for each situation. I haven't tried castor yet. Let me know if you have any specific questions and I'll try to answer them.

Sorry but which gauge are you referring to exactly?
