MG MGB GT V8 Factory Originals Technical - Panhard Rod

I am looking for manufacturing drawings to fabricate a panhard rod for my 1978 GT V8 conversion,anyone out there who is able to help? drawings to include attachment brackets,shell stiffening,etc

Thanks in advance,rgds Trevor

If you use the springs I suggested there will be no need for a panhard bar as these springs being flatter give a lot more lateral support.

I have only minimal clearnce between my 6 x 15 KN Minilite style wheels with 195/65 x 15 tyres and the delipped rear arches but have no problem with the tyres rubbing.

Unless racing I would not recommend using a panhard bar, they are more trouble than their worth.

Kevin.

Why do you say that?

Trevor,
There was a Holden sold there with a beam axle and Panhard rod fitted as standard. The years were '86 to about 93 or so.

This is a well engineered arrangement and might help with some idea of sizes and attachment points.

One extra suggestion is to add an extra link to the set up to form a triangle.
The extra link runs upward at an angle from the Panhard attachment point across the car and fixes to the opposite side chassis.

Sorry I am not able to be a direct help.

Good luck , Pete.

Peter,

The main problems are that there is not a lot of room between the diff casing and the tank on the B and getting a strong enough mounting in the boot floor area.

The bar needs to be set up paralel to the axle when the car is sitting at it's desired ride height otherwise the bar will actually try and move the axle ecessively sideways under bump and rebound, it will still do this anyway to a certain extent as the bar goes through it's natural arc from it's pivot point.

If there is not have a problem with the axle location on a leaf spring set up provided the spring bushes are in good condition I cannot see what advantage there is by actually fitting a panhard bar in terms of handling, it's only going to add more bind into the suspension system which a similar problem to the standard anti tramp bar systems.

I'm not a real believer of needing a Panhard rod on a roadgoing B but if you are going to do it this is how to get it right
1 With your car at normal ride height run a stringline through from the centre of your front springeye to the centre of your rear springeye. At the point where the string passes the centreline of the difftube is the actual roll centre height of the rear suspension of your car in it's current form
2 If you are going to fit a Panhard bar it MUST without fail be at this height as the panhard bar height will be your new roll centre height and if you have the bar at a different height to the car's natural roll centre height all it will do is bind the rear suspension up as the body rolls turning your car into an oversteering monster. It will in fact have two different roll centres fighting each other. So take some time and measure it up properly
3 To make your car feel good with a Panhard bar the bar should be as long as you can possibly fit and should without fail be mounted to the body on the drivers side and the diff on the passengers side.
In my opinion a good pair of properly mounted gas telescopic shockabsorbers make more difference to a B than anything else but that's only my opinion of course and they need to be fitted at the correct angles etc to get the max. benefit from them
I guess my message if you are going to modify your car is measure measure measure and really have a good think about why you need this modification
Hope this helps Willy

Hi Guys,

Thanks all the info and advice,I am going with the reverse eye springs and the fitting of a lower leaf to the lower front area of the spring pack to minimise axle "wind-up"(as per Bill Guzzman's advice)and forget about the Panhard rod.

Depends how hard you drive in the corners. I resisted a panhard rod for years. I finally tired of feeling the rearend moving while cornering. Much improved with the panhard rod & no more scrubbing the tires sidewalls on the wheelwells.
