I've looked at that, read the description, and still have no idea what I'm looking at.

Mike,

Those rods/shafts go from the lower control arm to the front of the K-member on each side.

What's unusual is that the NHRA statement specifies the strut rods in the header. But in the body of the letter, they talk about the entire front suspension in general!

So are they going to have suspension teardowns in the barn to look inside all of the pivot points now? Fords too!

I put a call in today to a NHRA tech guy to help clarify what is meant by the wording in the post. I do not believe it is a worry to the GM cars, but could effect the Fords and Mopars with the front strut rods. Remember how an old Mopar would shimmy the front tires on lauch sometimes, that is what will happen again if this rule is enforced. The front strut rod has to be secured and stable for the car to run safely, especially at 150 plus MPH. This will not happen with the old Mopar setup, a long rod with two rubber bushings trying to hold it steady. Dyno

A few companies make replacement polyurethane bushings for the strut rods which are stiffer and more durable than OEM rubber.....and legal.

If it is enforced like the A Body suspension rule ( AKA WEBIE SUSPENSION ) in a couple of months it will be all forgotten about.

I emailed Div II tech and asked if the "front suspension" included the tie rod ends and steering components. I know lots of people replace ends with Heims to aid in alignment and bump steer. And fab draglinks. Awaiting a response.

Jeff, not calling you dumb, but you do try and play that way sometimes to stir the pot.

First gen Chevy II's have needed this mod. for atleast 40 years now..
I figured it was legal now..with all the GT FWD conversions out there...
I guess safety is a not a big concern this week...They used it up last week on the Stocker seats.
Remember...You need a roll bar in 12.85 Stockers ,,,for safety!

On my 62 Tempest... (not a Class car) it was cheaper to fix the struts this way, than to buy the old replacement bushings.

DAMMMM, How long are those collectors?

[Mark Yacavone]

Phil, It was a street car...3" exhaust all the way back.
The back part was made to slip off , leaving the standard long collector in place.
