3/4" Sway bar

Is a 3/4" Sway bar for street on an MGB overkill or too much?

Vince
 
Re: 3/4" Sway bar

For street? I would say it is overkill.
 
Re: 3/4" Sway bar

No. I use a 3/4" front bar and higher rate front springs as my normal street tune on all my MGs. Not much point going beyond that IMO.
 
Re: 3/4" Sway bar

3/4 is standard on MGB GT, so it isn't a huge step up for a roadster. I'm installing one on my '65 if I ever get around to finishing the project.
 
Re: 3/4" Sway bar

Steve, I think the largest stock bar is a 5/8" or 9/16". 3/4" was special tuning only IIRC.
 
Re: 3/4" Sway bar

So if I used it on a Roadster with GT springs it should be OK? I've heard of a larger sway bar doing damage to the rails that it connects to and some have ripped out.
 
Re: 3/4" Sway bar

It's gonna ride pretty rough with GT springs. I'd go softer in the rear before I went harder. Look at the factory racers. They sag in the back.
 
Re: 3/4" Sway bar

Stiff front and soft rear is the route to handling on the track, but not so much for the street, where comfort often trumps crispness in handling.

My normal street tune involves 550 lb. front springs and a 3/4" front sway bar.

Using the GT higher rate springs will tend to raise ride height on a lighter tourer, so you might want to look at the Moss stiffer springs which are stiffer simply because they use fewer coils in them, which also makes them shorter, lowering the front end. A 1" drop at the front is as much as I'd go for the street, lest they become a pain to drive.
 
Re: 3/4" Sway bar

Bill, how have you found softer rear springs to hurt ride comfort? Seems to me the opposite would be true.
 
Re: 3/4" Sway bar

The front springs I have were out of a lot of about a dozen I had. I used the largest diameter coil and the shortest ones. Some were up to 1.5" taller. The ride is hard but it handles like it's on rails. I took it on a 400 mi. round trip last year with Jeani, and it was fine by us.

It's not the rears that cause deterioration in ride it is the stiffer fronts.
 
Re: 3/4" Sway bar

OK, now I understand what you're saying. I only meant to suggest that regardless of the front spring rate, I would prefer to go softer than stock in the rear before going harder.
 
Re: 3/4" Sway bar

I have been running 7/8 on the front and 3/4 on the rear of my '72 RD for over 20 years on the street and they are wonderful on the track. Nice balance and almost no lean on the corners. If you just do the front you will increase understeer. The rear needs to be increased too to maintain balance. I forget the manufacturer of mine now after all these years but they recommended the combination I have and it works great and doesn't effect the ride. Moss used to sell these front and rear but I just checked the catalog and Can't find any rear ones.

I remembered the my sway bar brand, they are Addco. Stock number 144 for the front and 917 for the rear. Those numbers are for up to 1974. '74.5 to 80 take stock number 263 for the rear and the same as mine for the front.

Also known as decreasing oversteer. Which is exactly what is called for on an MGB. The bars you use, while fine for the track are serious overkill for the street - they simply aren't necessary.

A front 5/8" or 3/4" sets up street cars just fine (I prefer the latter).
 
Re: 3/4" Sway bar

Fine, that is the last time I offer any advice on stupid forum.

Why - you only want to offer advice if everyone agrees with it? Realistically that isn't going to happen on any newsgroup or special interest site I've ever visited.

People have different experiences and different opinions. The web can be a difficult place for anyone that can't come to terms with that....
