Does it make a difference what the offset is on a wheel with regards to scrub radius?
It does not seem that it would, given the stock suspension, no custom struts etc. Aside from that, what is the reason (aside from cost and availability) for using large spacers versus getting wheels that mount up with no spacer, yet are wide for flared cars? rich |

For anyone that has the chance........
Take a look at Frank Stagrano's (sp?) SCCA CP class dominating Mustang. Note the front wheels......now look at those that are .....er....not dominating. I had a brief conversation with him. IIRC, he said that was the 4th or 5th front end set-up on his car. One thinks someone else would notice....unless they're too busy building V-8 horsepower. (IMG:style_emoticons/default/confused24.gif) Randal: You went a bit over my front tire widths and it sounds like it worked. If so and you over cook it, you should hit the wall backwards.

(IMG:style_emoticons/default/biggrin.gif) Your right. Going to dial in a bit more front bar for the Cascade Lakes road course. Last year the car was loose on the third corner, which is a flat to off camber left. |

Your choice, of course, but I wouldn't change the set up to suit one corner. I've been caught out in nasty "off camber" situations also.....but just once per event. One is well served by easing off there...... (IMG:style_emoticons/default/biggrin.gif) |
