CSX3170 in Scottsdale

[Alfa02]

Scott, this series count's if the cone has moved? (But is still in it's Box?) As you know SCCA doesn't as long as it's still in the marked box. I've ran over a few bases, over the years (Moved the cone) but was still in marked area, as I'm sure you have. I can see the side pipes exhaust moving a cone. A course worker should have seen that. Good luck at Crows Landing. Tom.

This is not Scott it is Bruce, GoodGuys charged 2 seconds if a cone wiggled even if it was touching the box. The course worker called it, for 2018 it will be 1 second if in box and 2 seconds if out. We are looking at rotating the exhaust up so that it won't blow pylons down. The car had a touch of understeer because of the new low friction rear suspension. We are increasing the rear spring rate so that it will hold a tighter line on Goodguys courses..

A friend of mine (Jim Fitzgerald) told me along time ago....”Stiffen and Slide......Soften and Stick “........always adjust the end that doesn’t stick....

Just think about it for a while.......depending on your wheel rates....

Hi Morris
Jim was right, we always try to add grip not take it away. In this case, the front end is as soft as I can make it with out introducing too much pitch or roll into the chassis. Balance is even more important than grip in terms of corner speed so I am going up by 7%. The real answer would be a wider front tire but Bridgestone does not have what I need so we have to increase rear rate. I was running about 1" of rake which is more than I really want. Hopefully, with the spring rate change I can get back to .5" of rake. We have tested front spring rates in 25 pound increments so are pretty confident in this analysis.
