Thanks Rick. It appears that I still have some work to do on the front suspension.

I saw this car run at Mokan. Impressive. How big is that motor?

I still can't figure out how NHRA ever approved the Wiebe suspension system for Stock Eliminator.

I've got the rule book here and it clearly states the lower trailing arms must be non-adjustable and have bushed ends, no heims. Upper is allowed to be adjustable and have heim ends, but not the lowers.

The Wiebe lowers have heims and are adjustable making them illegal the way I read the rules.

Also, the rules state that the upper rear housing attachment point may be relocated, but it doesn't not state you can on the lowers (Alf system drops the lower front bolt below the frame with a bracket), clearly a grey area in the rules.

If I'm looking at the pictures of Alf's stuff correctly, the ends of the lower bars do not have spherical rod ends, nor are they adjustable. Now, there are other brackets on those arms that have solid rod ends that are adjustable, but the ends of the lower arms where they attach to the frame bracket and where they attach to the rear end housing have bushings and are not adjustable. The attachment point at the front of the lowers is possibly a gray area.

The front attachment point is kinda sneaky. The original bolt hole in the frame is not the front pivot point. There is a bolt there, but the control arm has a larger diameter "hoop" which at best is a safety loop. The actual attachment point is a heim end that hangs below the frame. Any heim is considered adjustable in my mind.
