McClanahan DQ in Dallas
 

Does anyone know what Ryan McClanahan was DQed for, in the pre race all star inspection.

Re: McClanahan DQ in Dallas
 

Heard it was wheel base.

I always thought the All Star pre race inspection was a correctable inspection.

They checked Stock and SS Wheelbase after Rd 1 of All Stars.

They Checked after Q2 Carbs, throttle bodies and pumped modified cars.

Sounds like Wesley must have worked the event...
They allowed me to correct the wheelbase at a Memphis division race. Problem was I had a front suspension falling apart.
Lucky for me they checked the wheelbase. Rolled the car forward and it got short... Rolled the car back and it got long...

Curious, what would the advantage be in a longer/ shorter than stock wheelbase be? Or is it possible offset? Rollout?

Re: McClanahan DQ in Dallas
 

Keith,
Extended roll out if one side is offset.
How is it offset?
One side at wheelbase specs minus allowance and the other side offset farther would be great for rollout.
You could go the other way too. one side a lot shorter.
Cover the beam as long as possible.
Start the clocks with the wheel the farthest back and stop the clocks at the finish line with the wheel most forward.
Make your side of the track shorter than the other guys... Simple, Aye

If the rear end is not straight with the frame rails the front tires would have to be staggered for the wheel base to check correct. "Maximum variation from left to right: 1 inch."

They are stock suspension, they move big time. I saw this not more than a month ago on a new 4 wheel alignment. What I measured was not what it showed us! ! I was off an inch!
These cars are getting hammered round after round with wheelies. It will not stay!
I assumed it was the stocker, i missed!

Re: McClanahan DQ in Dallas
 

What you state Barry may be true for 50+/- year old stockers but the front wheel drive conversion superstock/modified cars are built with a stagger to improve rollout. The purpose-built chassis does not move like the old stuff.
