Sway Bar sizes 70 911T

[Ken Hewitt]

Can anyone help me w/ sway bar sizes for frt & rear for a stock 1970 911 T?

[jond911]

Can't help you on your question but that is a very nice unmolested example of an early 911!

Like the center caps!

Nice car!

I think 15mm front and 13mm rear. T's normally did not come with sway bars so you may not have the mounts for the rear. The front should be a threw the body style. You should have the knock out plates for that.
I have 20mm front and 18mm rear with upgraded TB and shocks.
Nice looking example of a T!

Thank you.

Thanks DByers,

I do have the mounting hole for the front. Is it a big deal to add to the rear? I was thinking Weltmiester 19mm frt & rear...

Ken, the rear mounts requiring welding. I good shop can do that for you. If your in SoCal I would recommend TRE (they welded mine in). Also the new WEVO mounts would be worth the money. There is a thread started by Tyson that shows him adding them and a rear sway bar. Its a little different for a pre 73 but still easy enough. Do a search on sway bars for some insite, but 19/19 might be a little stiff with no other work done to TB and shocks. Also if you have never or dont know when bushings were replaced now would be a good time to investigate that also. Mine hadnt been touched since the 1971 and it showed in the handling. Shocks were at least 18 years old and they were shot.
My suspension now is very nice. Stiff and planted at the track, but still drivable on the street.

Early through the body front sway bars are supposedly more efficient than the later lower mounted ones. The ’72 – ’73 S had 15mm front and 15mm rears. In some cases earlier cars actually had smaller fronts than rears. As already stated you really don’t want to go to big on a streetcar. I’ve used a 13mm front only on our ’71 for a number of years with success in AutoX events.

David,
I have heard that running only a front sway bar on an early 911 with pretty much stock suspension is a good way to go. I am not an expert, but from readings and digging around it has something do to wtih keeping the rear traction without LSD on some early 911's. It would be an easy upgrade for Ken and he wouldnt have to do any welding yet. I recently saw a threw the body 15mm bar and drop links on evil bay for less the $100. The adjustale Welt would work at full softness also.

The Weltmeister rear sway bars don't require welding. They mount with a U-bolt that goes around the rear torsion bar housing. The drop links attach to a special bolt that replaces one of the eccentric bolts on the spring plates.

Bump please

Nice car, Ken. I just went through this on my '72 T. I went with the stock 15mm both front and year and am very happy with that choice. The front is a bolt-in addition. The rear is a bit more of a challenge. Here is a thread that I started back when I was in your position. It has some photos and an explanation of my rear instal. I've been running this set-up ever since, with numerous street miles and track days on it. It works great and has held up just fine.

What do you think of my sway bar mount
