Hi,

 

I am interested to find 12" wheels with the highest ET value.  

Would you point me to the right direction?   Like 12x5.5, and having the higher ET value, like greater then ET30.

 

Thank you.

Positive offset, in the the region of +30's, sets the rim back in the wheel arch towards the suspension. Negative offset , usually in the -5 area, moves the rim out creating a deep dish look.

 

 John Brown Wheels have a poor reputation on here but we bought a set of their 6 x 12 Minilights which had a -7 offset which gave us the widest track, for racing. They do a +31 offset in the 5 x 12 Minilight.

but you are best moving the rims in and out so you are not overloading the bearings etc.

And, to keep the good handling, you want the scrub radius to be the same as standard. But with respect to where in the contact patch if the wheel is cambered?

 

And, if the wheel is very much wider, should the scrub radius be changed in proportion to the width, or fixed? There are arguments for both.

 

Have fun folks, tweaking your geometry. You will never get it right, only better, or worse, and in most cases, worse. Alec knew what he was doing with the back of his fag packet.

Have a look here too under 12" http://www.wheeldictionary.net/

 

Standard 12x4.5 wheels are +35 (Steel and Alloy)
