Alf Wiebe A body rear control arms

[Greg Reimer 7376]

I installed the Alf Wiebe rear springs and shocks from the rear suspension kit in my '68 Chevelle stocker.It definitely straightened out the launch by eliminating the corkscrew tendancy of these cars. I want to install the lower arms and the upper wishbone assembly so as to properly preload the chassis and center the rear end housing(it's a 12 bolt), but now I hear that the set up is either illegal or soon to be. There's at least 10 Chevelles running this setup that we know about, and Tony Janes and I are a little put out that we can't use it,especially after one is on his car. I haven't seen any posts or official response yet. Anybody out there know about this?These kits have been out 10 years or so,they are excellently engineered and constructed,and I would like to use it.

Your racer info says you're from Glendora Ca.Can't you just walk over to HQ and inquire?It's only a local call on the land line.Just kidding ,couldn't resist.
I heard that the Weibe setup was going to be outlawed in Stock.Good for a few years then all of a sudden it's illegal.Go figure.

Why ?

Is a Moser 12 bolt legal? HRpartsnstuff bolt on antiroll bar? Who needs Alfs?

[72Malibu]

Maybe it isnt going to be legal any more because its not available to the masses any longer?

[Alan Roehrich]

Last I heard, you can buy Alf's stuff. So it is available. It is bolt on as well.

Because when compared to other suspension systems, Alf's system is more consistent and adjustable for changing track conditions. When used in heavy S/SS cars, where you are not allowed to run a fiberglass hood, aluminum heads and light weight components as used in other sanctioning associations, Alf's system shines.

I was told ,years ago, by Wesley, that you couldn't add an upper or third attachment point to a Stocker suspension. That, that would constitute a ladder bar. Slapper bars are considered to have two points.
It seems to me though, that wouldn't be the main point of contention with the Weibe system.

Tell me, Where is the front lower pivot point on that style trailing arm?

You think that car is not heavy? That is a heavy BB car and he has the Back Seat in too. It may be a little lighter in the front but not much with that big ol' engine in it

Thats the famous "Green Weenie", The "Green Weenie" is a 9 second Chevelle.

Oh, and the "Green Weenie" doesnt have a transbrake in it either, its a street car

Well, the rule book for 2008 says,"Rear trailing arms may be replaced with NHRA accepted OEM type aftermarket units.Aftermarket lower unit must be non-adjustable and have bushed ends(no heims).Aftermarket upper unit may be adjustable and use heim ends instead of bushings." I guess the purpose in that is to prevent even the appearance of an alteration in the wheelbase of the car.The Alf Wiebe set up allows for centering the rear end housing, and adjusting the differential pinion shaft angles. It also allows for suspension preload up to a point. Another thing,how many 64-72 cars of any make all have a square frame after this much use and years of abuse? Drag racing isn't exactly easy on things.Tony Janes had a discussion with some tech people and apparantly, an official word is forthcoming, probably by the start of next season.Hopefully,unanimous interpretation of acceptance of what constitutes compliance will be the result.
