Default subframe connector

I had one back end of my car jacked up the other day when I was changing my struts and I notice that the body does a little twist. I was wondering if anybody has installed subframes to there cars,My is a 95 SSEI. the ques. would be were did you get it or how did you get it made and install? I would really like to get this done to the car so that she will be a little stiffer.This way it can help out the handleing.Thanks

Just accept the fact that noone makes parts for Bonneville'* except me and SpeedyGuy. Subframe connectors will most likely be done on my car just to see how well they do. The body twists even though are cars are pretty stiff is because our cars are so heavy anyways. So basically you have to be patient for parts to come out just for the Bonneville.

If you really want something made it comes down to numbers. Most of the time we need around 10-50 people to make a product happen. So if you are interested see if you can get people who are interested. If you really want them either Hector or myself can make a one off product just for you but the price will not be cheap. Anyone else interested? I can work out a price if people are interested. I have a 1995 and I have access to a 1994-92. I know hector has a 99 so I am sure something can be done. As for your direct in the moment need I can do a one off for you and have it made out of almost any material you want aluminum is good if you want to keep the weight down. I can also do steel so you can have it welded on for better rigidity. Also a better rear sway bar is another helper.

Don't do aluminum for a subframe connector, the cost and the pain it would be to weld it to a steel frame would be annoying. Plus you would have to use T7075 Aluminum and that is not cheap in itself either. I say be patient for subframe connectors, it isnt a real need and w/o other suspension modifications to the car it wont help your car handle any better.

I am going to a local welding shop and see if they can do something for me and I will keep you guys updated.
I was interested in the rear sway bar also but the only thing that I saw was a 7/8 bar,I measure my with a ruler am it look very close to that, My car is a 95 SSEI, I am not sure if it comes with a bigger one then the SE model.

Great idea but be very careful with who you go to make sure they are good. Very good. Because every shop has a god welder "oh ya I can do that for ya" but that’* not good enough. Make sure the person involved has done this before. Find a local company who sells sub frame options for other cars. Then ask them who does the welding. That way you are 100% sure you can ask other customers about the specific job. I am sure you have thought of this but I figured it is a very important bit of info for those who may not know what to do.

Here’* a bit of info on the sway bar deal. As you make the rear sway bar bigger you will find it gets stiffer in the rear eventually you will notice the rear end gets loose very easily. Now you don't have a plowing effect but you have a loose reared. The same goes for the front. So a balance is very important. Same with the sub frame connector in a different way you need to be sure that the connector is perfectly symmetrical and balanced otherwise your ride will be a mess. I will find my helpful tip site that I have used in the past for reliable info and post it.

Diameter is generally the easiest concept to grasp, as it is somewhat intuitive that a larger diameter bar would have greater torsional rigidity. Torsional (or twisting) motion of the bar is actually governed by the equation:

twist = (2 x torque x length)/(p x diam4 x material modulus)


And since "diameter" is in the denominator, as diameter gets larger, the amount of twist gets smaller. Which, in a nutshell, means that torsional rigidity is a function of the diameter to the fourth power! This is why a very small increase in diameter makes a large increase in torsional rigidity.
