Toe in, and other alignment settings?
Krismc - 27/3/11 at 07:21 PM

Anyone, got a rough guide on how to adjust my toe in the garage,

You may have seen ive posted in the MNR section as my car is scary light at 50MPH, ive been advised to adjust the toe, not sure how or too what but ill give it a go!!

I'd start by getting everything straight first, hang on I'll try a find some pictures how I did mine....

Cheers

Your car needs four wheel alignment.
Rear toe is possibly more important than front, because if it's wrong, you can't steer around it.

You need a proper 4 wheel alignment by someone who understands what they're doing.
I've driven a car which had bad alignment and when the accident eventually came, it was only good luck that I squeezed between the road sign and the lamp post.
Once I sorted the rear toe in, it was perfectly stable.

Seriously, don't just have a go.
If you're not sure what you're looking for, get proper 4 wheel alignment done by someone who does know what they're looking for.

This is how I initially set mine up Linky which got me nearly there, then fine tuned it, I would recommend getting it done professionally if you want it spot on.

Cheers mate, its just been to mnr so its set up safe, it'd just id like to have a go myself, I can't afford a full setup yet and I don't plan on driving like a tit.

Thanks

Eh, its already been set up at MNR and feels scary at 50mph??? Something doesn't seem right. You can use my technique to check how they've set it up.

could you also put a meter long section of box against each disc(held on with a G-clamp), measure the distance between them in front of the car and then near the end of the box section to get the wheels aligned straight, then adjust from there using a bit of trig to work out toe settings from a baseline?

I used a laser level and a tape, Placed the level on the wheel and shone the level at the floor marking 300mm in front an 300mm behind each wheel with chalk then measured between the marks on each side of the care . I then adjusted accordingly hope this makes sense. Car feels fine doesnt wander and handles well enough

It went for iva, and a few other things it was there a year, I'm sure they toe it out so that it self self centers at the test centre, then reset it up afterwards to a nominal setting, but with part changes, wheel changes and all the 100s of new parts bedding in, the car has only done 30-50miles including being built.

I've just improved my handling, I was expierencing the same as you, but I knew my toe was set to 0.5 in. It turns out I had no Rake (front to rear reide height) once I wound the back up to have 22mm more than the front it completely transformed the handling and I didnt have the scarey 50mph+ issues. (thats 22mm without my lard arse in the seat)


David Jenkins - 27/3/11 at 09:40 PM

Oh - I'd forgotten that - I also had to set my rear about 0.5" or so higher than the front. You really don't want the front higher than the back.

If it handles at all with 0.5" toe I would be amazed! I hope you mean mm or degrees

now let's add bump steer into the equation, under heavy acceleration/braking it has a wonderfull affect on toe in/out.

We used a facsimile of this method for initial alignment of the rear suspension on our Phoenix. It only works if the car is at correct static ride height with the weight being correctly supported by the car's springs. We used blocks of wood under the uprights. Don't try it with the car jacked up.

Ah, a single missing word causing confusion...apologies...

... but I knew my toe was set to 0.5 Degrees in
