Shout outs to Rick Delamare (turfer) and Steve Ingersol for the DIY.

 

Nice DIY, but I choose to have someone with a computer and machine do mine

If you've raised or lowered the car, it's probably a good idea to get an expensive "racing alignment" at a shop with a good laser setup.

However, if you're just experimenting with different toe settings on a car that's already known to be basically straight as far as the thrust angle goes, it doesn't hurt to know how to do this on site somewhere.

 

Didn't someone on here put together a wood-and-string home alignment jig?

I'm sure half the RR Forum has.

 

I didn't notice that you were working on the alignment at the track

Thats because you are going too slow

 

Shame on C-speed for posting that. I can't even begin to list the inaccuracies with this "method." If anyone wants a DIY alignment, check the RR forum archives.

Hey man, as long as it's sorta repeatable, and you don't care if you're +/- an eighth or sixteenth, it's good.

I mean, who cares if I'm at zero toe or an eighth out. As long as I can measure against "something", and I can toe in and out from that, I'm happy with it.

&lt;--- Chris, running a quarter inch total toe out in front via strings... not sure how much it would be if measured on a rack/laZ0r system. But I can take an eighth out of it if I want, or add an eighth.

We have time.. why do you list the inaccuracies??

 

yeah, if your on track a lot.....your alignment will get f'd up all the time. I hate that crap.

It's not like your going to be winning an F1 race or something, eye it up and rock out.

 

Don't get me wrong, I love DIY alignments. They all have inherent inaccuracies, but the goal is to minimize the error. This method doesn't do a very good job eliminating room for error. Here are a couple problems I see with this method.

1. Running strings off the bumpers. The goal is the create a "box" with the strings. Ideally, the strings will run parallel to the centerline of the car. Show me a race car with bumper covers that are either 1) straight, or 2) are the same width front to back such that running a string in-between will yield lines that are remotely parallel to the centerline of the car.

2. In picture "1987," they have the string wrapping around the edge of the tire. If the string is touching the tire, it's not possible to get any sort of accurate toe reading.

3. This method also assumes that the front and rear tracks, wheel widths and tire widths are the same. If your car has a wider front track, for example, the strings will not be parallel to measure the rear toe.

Toe plates, tire scribing, toe bars and proper DIY string setups will be more accurate than this setup. Cheap and easy doesn't have to be wildly inaccurate.
