How much toe on the front?

Hi Chaps,

Sorry another one, when I fitted the new rear suspension the other weekend I took the chance to sort out the front toe, it was massively out. One wheel was toed out while the other was toed in! Resulting in going right with the wheel straight.

I sorted it, but decided to Toe out both front for better turning response, but at the expense I guess at inner-edge tyre wear.

Do you guys run with the front toed out at all? Straight or Toed in for more stability? If so by how much?


Thanks.

I have two twos. Last "Total toe" for one was +2.4mm, and the other was +1.1mm According to the printout the "Target Data" for that is +1.0mm.

We're currently running neutral toe on the front of our track '2, I think the turning response is perfectly adequate with stock toe-in settings to be honest but we thought we'd try 0.0 while it was in for an alignment. Doesn't seem to affect straight line stability too much either so we're happy with it, we do run quite a lot of camber as well: -3.0 degrees on the front, corners like a house fly!

Thanks guys for the info.

I just wondered as I know a lot of road cars have slight toe-in for more straight line stability. I heard some people running negative on the rear and positive on the front.

I opted for I think it was +3mm front, which may be a bit excessive, seems to drive straight and steering is very sharp. Might re-visit it though, I thought neutral might make it a bit unstable, but sounds like that isn't the case from your report hachiroku.


Thanks.

I run (and have done for years) zero toe front and rear.

Very happy with handling and stability.

I checked the specs. They are for toe-in front and rear, but it's tiny. 1-2 mm.

So zero toe and 1mm camber is the way forward?

Did Mr T arrive at a particular spec when he designed the car? Yes
Since they left the production line many variables will have taken place.
So I am of the opinion each owner/driver/car will have their own requirements to make the best of the car as it is now.

For me, I'm a B road junkie. No interest in track time whatsoever. So taking one persons stats and overlaying on to your own car is in my opinion a fruitless excerise.

I went to wheels in motion. They asked what/where/how is the car going to be used. I answered, they dialed in the geo to suit. (they dialed in their in house fast road setup) And I've never been happier. It suits me just grand. Will it suit someone else? No idea.

But for a refrence point I have attached the print out. This is with fresh tein s springs,  KYB standard shocks and AD08Rs.

I've been trying to find the original Toyota specs for toe and camber on an 04 facelift. Do you have a link please? Thanks!
