UMMM, explain panhard kit please. Been meaning to ask that Q for a long time.
Rob
do i want one?
Robert a panhard bar is a type of lateral chassis support system, there are several different types like a watts link, wishbone, mumford link or panhard bar. In short a panhard bar is a bar the connect one end on the rear end housing and the other end is attached to the chassis. Where a lateral control device comes into play on a car is when hard cornering forces occur this keep the rear end and the chassis in the same place, in otherwords the rear end does move back and forth laterally under sideloads.
Thanks Hap. Does the rear sway bar on later Bs do the same thing? Or are they used without the sway bar?

Panhard rods also prevent the coil springs from "winding" up upon acceleration, which causes the rear wheels to "hop", causing a loss in traction.
Why is there a $100 difference between WW and DW rods? What is different about them?
Rusty alot of racers use in addition to a panhard bar and sway bars a 5th link, for what you're talking about as well, the bar would go from the rear end housing to the chassis, normally forward of the housing to the chassis, this keep pinion angle at a constant as well. Most all my race cars have a lateral control device, (I prefer a panhard bar or wishbone for thier simplicity) a rear sway bar and a 5 link, somtimes with a rear leaf spring car, add anti tramp bars to that as well.
Andrew, I think you're thinking of traction bars.
Panhard rods are used to locate the rear axle laterally (side to side) on the chassis (or body in the case of a unibody car).
Most are adjustable.

The first picture contains a MGB Distributor also, this is obviously not included in the kit :)

so to sum it up, the panhard rod kit would be a good choice to also put with the anti sway bar? And this one will bolt on to a 1980 B with no problem and have room for the sway bar?
Anybody considering a rear sway bar and a lateral control device for a MGB, needs to look at what David Headley (long time SCCA and vintage racer) has to offer as well, it's pretty much a bolt-on. Picture of his rear supsension can be found in the motorsport section, search up Fred McConnell's post there and you'll see a picture of it.
All the Panhard rod is, is a stout shaft (people tend to underestimate the forces in play) attached at one end to the axle and at the other end to the chassis. Attaching to the lower leaf spring plate with a welded on extension is common; this one uses a special clamp to the axle tube. The other end needs a bracket off the frame - also stout or they snap off. As they follow an arc, you want the ends to be at as close to the same level as possibe, and attached as far apart as possible.
Do you need one? If you are racing, yes, they are an advantage keeping everything where it needs to be. On the street, if you run wide wheels and big rubber and a slight sideways movement of the axle can send the tire grinding into a fender lip, yes, it is a good way to go. If you are running normal rubber and don't compete with the car, you can probably save your money as it won't give you much for that sort of use except bragging rights ("Hey, I've got a Panhard!" Response: "Huh?")
Hi Hap,
I cannot find the thread you meantion that has a picture of Dave Headley's rear suspension offering?
