Toe in for all cars but just a touch, but he more the inside scrubs off, the more they can benefit from toe in

Smart 'Rocco there. I just love Skyrockets. Wish I'd kept mine

I think their is some confusion here. I'm confused anyway lol.

I've been having full laser geometry checks done for nearly 12 years and always been told:

Toe In helps Straight Line stability, it does not improve turn in to corners.
Toe Out reduces straight line stability but improves turn in to corners.

I have no idea what the Cupra is set up like as mine is running fine so not had it checked yet, but I will at least yearly. My Scooby is running Toe Out on the front though as originally set at the factory, although mines been tinkered with slightly.

Well the correct thing is to run it as specified by the factory
Toe in helps turn in as the wheel that gets weighted up is then pointing the way you want to go.
Running toe out is an amateur way of trying to increase cornering ability which is quite different to turn in and the degree of toe out than can practically be dialled in is actually completely insignificant to the relative toe out generated under lock.
Steering geometry allows the inside wheel to turn at a stronger angle than the outside wheel as it needs to follow a tighter arc, called ackerman geometry if anyone wants to look it up ie when on lots of lock the front wheels have toe out relative to each other. Simply adding more static toe in and believing it to help simply suggests that the best automotive engineers in the world couldn't get it right when they designed the car - err no! If a bit more toe out would help they would have desgned in more ackerman to begin with. There is no downside to ackerman. If the car could use more they would build it with more.

However and whatever, anyone who has a road car wearing tyre insides off will benefit from
a) a bit more toe-in or less toe-out
b) firmer bushing
c) replacing any worn joints

Makes sense!

Scooby goes in for service/MOT shortly so may ask to test the above. My only concern is that it's set to toe out as standard so may have an adverse affect but worth testing if it prolongs tyre life and possible improves turn in.

Also, if all these Cupra's etc are eating the inside's of tyres does that not suggest they are running slightly toe out ? My Cupra will be going in to Seat shortly for some work so i'll query what the standard toe settings are, unless anyone has them available?

TTS are continuing their offer til Spring, so go there.

The Ibiza makes the front wheels look like they're toeing out, this is because of the curved shape of the front end.

as i read through the section on rear wheel spacers i just found out that the front wheels are set slightly more apart than the back surely this is a problem when getting algned as the front wheels wll always be toeing out? think i wil get my car toed in slightly maybe only 2 degrees or so wil make all the diference wil this mess with the handaling a great deal?
