[Fot] TR3 wheel offset

[Roger Williams]

There is this thing called scrub radius. When the factory engineers designed your car they set it in a proper position. If you add spacers or get taller tires or shorter tires or install the wrong rims you can make your car dangerously unstable at worst or at least make parts wear out and or break important bits causing a crash. Making a racecar unstable is not a good idea. If you do not know where the scrub radius is on your front tires...maybe you should. Attached is a simple look at what can get very complex and dangerous.
Cheers
Roger Williams

You can see where the previous owner notched the leaf springs so the tire won’t rub, so I suppose I can make these wheels work but I might be giving up track width.
