ND1 Caster question

Post by DougA371 »

Just installed 225/45r17 Maxxis VR-1 on my Konig HyperGram 17x8 et45 wheels. I have rubbing towards the front of the front wheel well liner in moderate turns and heavy rubbing backing up in a turn. I fixed some of the rubbing by using an heat gun, but not all. Could reducing the positive caster give a larger gap between the front liner and the tire? If so how much would I need to make a difference?

YES, for cars with 225/45 we usually back the caster down to a range of 5.5 to 6 and that helps a lot.

I couldn't really tell a difference. But I've only taken this car on the track once and it was with the new settings. I did notice that the rubbing was gone and that is really what I was looking to accomplish.
