I am looking to stiffen my Cuda up a bit. It is finished already so I do not want to cause alot of underside paint damage with extensive welding. Some is O.K. I will be using the Alterkation front end with the XV rad support and cowel braces.
This is a 528 HEMI, 5 speed car. Any suggestions on whose subframe connectors would be best for this application?

Best would be ones that require cutting and welding to your floor, period. Anything else would be a compromise. There are bolt on ones that don't touch your floor and just attach at the front and rear subframes. Although with a 528 and a stick shift I would at least weld those at a bare minimum. I would suspect bolts would tend to want to wallow out the holes they're in and with bolts there will always be some flex.

Get the Competition Engineering ones, weld the saddle and cross member points and your good to go. Minimal welding with a substantial improvement. While perhaps not optimal, even a bolt in connector provides a big increase in rigidity over nothing.

Thats great, thanks. I know Hotchkis, XV Motorsports, M.P. and a few others make them but did not have any personal experience with any of them and don't really feel like experimenting!

These hardly qualify as limited welding.

The XV's are a joke too just buy some 2x4 rectangular steel tube and make the yourself $150 less and will be the same amount of cutting and fitting work

True, but it won't show nearly as much as the cowl support welds, once they burn through the engine compartment paint by the shock towers.

The Hotchkis connectors only require welding on the front crossmember. The rear bolts on to the front leaf spring mount which might be an advantage.

I actually have both the Hotchkis and US Car Tool connectors sitting in my garage. The Hotchkis connectors are a lot easier to install but hang down lower than the US Car Tool connectors. So I am still deciding which I will use.

Here's some pics of the Hotchkis installed, they do hang down. Only noticable when up close and looking at low angle.

Should have thought of that WAY before painting the car!

Thanks for the input guys and your absolutly right, I should have thought of this first but I bought the car finished and want to improve it (of course!).

Desomod,
Our subframe connectors ( link ) are easy to install. They bolt in at the rear and require just a little bit of welding in the front.


This image shows the front tacked in and ready to weld:



Read the full instructions in this PDF:
http://www.hotchkis.net/_uploaded_files/4011s40104011linstructions220file.pdf

Our subframe connectors are very effective and have been working great for our E-Max Challenger.



They really increase body stiffness, as you can see in this photo of a Challenger with one jack stand.

Hotchkis.....can you give us some comparison on your connectors vs say the typical mopar subframe connectors that are welded in between torsion bar crossmember and rear sub frame? Yours ultimately are just bolted in place front and rear correct? Does is make them stronger to go to spring hanger even though they are just bolted in place? What has the testing shown for your style vs. the typical weld in connectors?

Hey Wegner426,
If you get a minute, check out the following PDF document of our installation instructions. You’ll see that the rear of our connector bolts in and sandwiches the floor pan with the front leaf mount of the leaf spring. The front of the connector is welded to the lateral torsion bar crossmember. It also intersects the forward frame rail to give it optimal support.

You can read the full instructions in this PDF:
PDF DOC


We designed ours to be much easier and less invasive to install than other brands and they REALLY work.


This image of the car lifted by one jackstand illustrates the rigidity of our subframe connectors.

The owner of this car is a drag racer, and she reports the car tracks straighter down the track and launches harder in the 60ft after the subframe install.

If you want to find out more details give our tech department a call: 1-888-735-6425
