911 suspension compatibility question Options

[jt914]

Can anyone confirm that this swaybar and A arm setup will work with 72 911 suspension?

[Mark Henry]

I think it will, but the sway bar is the underbody type, bit of a hack on a 914.
I have an aftermarket one in my scrap pile.

You will need 911 torsion bars, 914's wont fit, different number of splines.

Thank you for the replies guys, this isn't for my car. I have this setup listed for sale and some inquired whether it would work for his project or not so I figured you guys would know. I appreciate it.

I know one of the members here runs an underbody sway bar on his GT.. I will also be.

Note that the customer will need to find the body brackets for the bar. They add onto the supports that go across the compartment where the steering rack lives.

The underbody sway bar will work. Richie Gunther had to run a similar sway bar setup back in the 70s as the SCCA wouldn’t allow the through the body sway bars. They never seemed to like Porsches.

That set up is 74-up 911. Not recommend unless you are going racing. Bar is way to stiff for everyday use.

thanks for all the information. much appreciated.

However it was used as stock in 911s. Were they also too stiff?

I do not want to make a mistake.

Thanks!

911's are much heavier cars so the suspension doesn't always translate perfectly to a 914. the torsion bars and sway bars are stiffer on the 911 and can make for an overly stiff ride on a 914-4 thats not destined for track use. Everybody has there own preferences, driving style and road conditions but bigger isn't always better if you want a comfortable ride.

Those are 74-89 underbody sway bars. These will only work if you have the aluminum cross-member, rear tie-connectors and underbody specific sway bar bushing brackets that mount to the rear tie connectors.

You need the full system to run that sway bar.

The a-arms by themselves will work. If you want to run a through-body sway bar, cut off the sway bar mounts and have the new drop link mount welded (better) or bolted in place.

About 600 lb difference between 911 and 914.

I beg to differ. I just drilled and threaded a hole for the mounting bracket into the steel crossmember.



I kept the steel tube crossmember because if fit better with the rad hoses, otherwise stock 911 susp.

The compatible of the bar depends on the sum of all the suspension components and car configuration and use. Underbody sway bars come in 20 and 22mm. Due to the different fulcrum pivot distances the 20mm underbody is not as stiff as a 20mm through body sway bar.
If you go with the 911 torsion bars you now have stiffer torsion bars. Rear springs should probably be stiffer than stock.
From my experience a 20mm is not too stiff for the street.
If you want to stay with stock six torsion bars I have a pair that are from a SWB 911 and are the same size as 914 but will work in the 911 A arms with the loops for the sway bar.

Sorry, you are totally wrong on the sway bar.

I have an aftermarket one in my scrap pile.

I've had a couple of guys have asked about my scrap pile sway bar, I doubt if I can find it as my scrap pile is now 20' round x 8' deep, likely several tons.
Every 4-5 years I take it in and use the cash to help pay for a holiday. maybe I can find it then, but it's highly doubtful if it will be complete.

I believe it's an Amco aftermarket bar, in fact I had both front and rear. I do know where the rear bar is but not the hardware. It's a real hacky POS.
