Toe in

[Silver-Arrowz]

Quick one. What are the affects on having toe in on the front and rear suspension?

Thanks!

Toe in is often described as a "stable condition". It makes the steering less responsive, so the front can feel a bit doughy, so the turn in to corners is not as good. However it is good for driving on freeways where you want a large sneeze factor. Small movements of the steering wheel don't effect the straight line running.

This is similar for the rear, it makes the rear end less responsive to inputs (eg; throttle). So it can lessen the loose feeling you get when applying the throttle or backing off or braking. The downside is too much can reduce the manouverability in sudden direction changes.

In a car where you're aiming for good handling you would run a bit of toe out on the front and maybe straight ahead on the rear, or a little toe in if it feels loose.

Hope that helps:cheers:

I found it a bit the opposite. I had a wheel alignment done on my GT-R & the shop stuffed it up. I gave them a total toe in measurement which they interpreted as a per side measurement. Result was the car tram lined like a pig until I took it back & asked very politely if they could do the job properly. Please.

So I would recommend not running too much toe in.

My present settings are 0.3 per side at the front & 0.5mm per side at the back. Seems to be ok at that.

So on the road less toe in can result in a more stable car. On the track is a different matter. Depends what you want.

Tramlining is not realy a front stability issue, it is a separate effect of toe in. You can have car that is stable at the front but still tramlines. Conversely you can have a car that is unstable but doesn't tramline.

You can also have a car with zero toe or even toe out that tramlines. It is usually more to do with SAI than toe, although caster can affect it as well.
