The archives on guide flags are full of great information. Cheater's Tome et al. As a recently resurrected racer, my question is primarily about guide tightening/tension.

 

I've read that spacers on top of the guide below the hole, after sanding/truing the guide post, then tightening is preferred. I've also read elsewhere, and heard from some folks, that spacers top and bottom or only top, then tightening is the preferred option.

 

After decided that bit, how much tightening is desired?  Loosey goosey with a bit of wiggle so that the car will freely orient if held vertical by the guide. OR, snug with no wiggle and snug to the edge of no play at all when held vertical.

 

Too tight, the guide will stick sideways if/when the car comes off on a sharp curve. Makes it hard to marshall quickly and over controlled.  Too loose and the guide slops around shedding speed and less control.

 

I have a set of gap gauges. Is there a preferred gap or is it a matter of gaining experience and feel again?

 

I'm racing on flat tracks BTW in Retro Can-Am, F1 and Flexi Indy/NASCAR stock classes. Assuming the rules and all things being equal, it's about the little things isn't it?

 

Thanks!

Scott

With the lead wire installed, braid in the guide, you should tighten it with as little play as possible, and still self-center.

Once in the race, if your guide doesn't self center, you'll regret it, especially if you unfairly get frustrated with the marshals, for struggling to get your car in the slot.

This new/old concept doesn't depend on the threading of the nut matching the threading on the post.

Thanks for the input on guide tightening. That works for either nuts or collars.
