Tom Urban at Banski Motorsports has started supplying rear trailing arms and camber rods again. He has also posted some articles on the spacer and mounting plate requirements so that someone can make their own if they choose. He has been a great help and I can't say enough good things about him. Here is the email he sent me last night:

"Hi Colton,

It took me a little longer than I thought it would but I have all the info compiled that I had referred to below.

I've identified a spacer kit for the camber rods. As suspected the stack up isn't exactly what's needed for the C4 application but it shouldn't require much more than a 3/32" shim or spacer. I'm also going to continue to supply the frame adapter plate and hardware kit. If you check out the website you'll notice that purchasing the kit is much more an a-la-carte experience now.

Here is a link to the camber rod page specifically. At the bottom are links to a few different documents that outline the setup and assembly processes as well as how customers can make their own spacers if they so choose. The spacers & adapter plates are also listed in the order center as well.

Hope this info helps and if you have any questions just let me know. Feel free to share this info as well, I'd like to get the info out that the camber rods & trailing arms are still available, even if in a slightly different form.


Best regards,
Tom"

Hope this helps anyone looking to upgrade their factory system

I have the entire kit from banski and they are holding up very well. I snapped two oem trailing arms and that was what began the banski purchase.

My only complaint is the price, I copied their pieces and built it myself using the same components and it was less than 1/2 price. Of course not everyone has access to the right machinery to do this but there is definitely a large mark up and then a "corvette tax" on top of it.
Overall I am very happy with the pieces.

If you buy anything from banski ALWAYS get the rubber dust boots especially for street driven cars.

I also have the full Banski system, works awesome! I would recommend it to any C4 owner it makes BIG difference.

This is a VERY timely thread. I have been looking at the Banski pieces. I'm planning on getting a set of Camber rods then hopefully the trailing arms later this spring and it's good to hear that they are quality parts. The only thing keeping me from pulling the trigger on the Toe Rods is not being able to find a bracket for the differential side of the rod. The Tie Rod conversion bolt is easily sourced from Speedway.

Have any of you had any issues from guys at the alignment shop not knowing what to do with the custom parts? Or, have you had better results from the alignment shop with the better parts?

DMITTZ

The guy that does my alignment is a good friend
and he let me watch as he works, he said my car is one of the easiest to align of any he has done. And watching I really did seem pretty easy as long as the shop has decent equipment.

Lt4-396

Yea doing a wheel alignment with the banski kit or any rod end takes maybe 10min. And is much easier than oem equipment

Glad I saw this thread! So I'm understanding this correctly...we can now go back on the Banski site and order the camber rods and such just like before? I thought I read that they were stopping C4 production pieces all together. I had been planning to pick up a complete rear set up but didn't before I read they weren't available. This would be great if they're back to making these pieces!

Just one more enthusiastic thumbs up for Mr. Urban. He's very responsive and super helpful in answering questions or getting small replacement parts.

Guys, not to sound dumb, but what does this do?

MatthewMiller

Best explanations are found on the Banski site. Really. It's not marketing jibberish, but rather a detailed explanation from an engineer (or at least a guy with serious engineering knowledge). The very short version is that these links remove the vagueness of rubber bushings in locating the rear suspension, and they also get rid of the camber rod alignment cam that has a bad habit of moving and changing your rear camber setting. For that car that will just see cruising street duty this all may be overkill. For a car that is road-raced, autocrossed, or maybe drag raced, they can be very useful if class rules allow them.

It doesn't matter much on the things you buy, you always pay someone in the middle for their time and materials also. You also have the time, money and materials required to assemble the kit and no one does that for free. Personally I do not have a problem paying someone for their designs and using their resources to make it possible. I'm sure Tom does not make everything himself, he contracts some of that out or buys it from other places to his specs. He deserves to make a profit from his design, it's proven and well spoken of.

I bought the entire Banski kit and have it to finish putting on my 86. If I had an issue with paying Tom's price for the kit I wouldn't have bought it, but I did. This seems to be one of those 'you get what you pay for' and I say that in a positive light.

I have nothing to gain here, I'm a paying customer like so many people. I have had an occasion to contact Tom on questions and issues and he's been very helpful and willing to share information unlike others I've contacted over the years.

easy alignments, reduced weight (maybe 2 lbs or so) -better ride and consistent camber/toe across a range of wheel -suspension travel (by eliminating bushings that can compress).


better ride is from elimination of stiffened bushings - and transferring road forces thru springs/shocks instead of bushing mounts into the body.


go over a set of railroad tracks after the install and you will be amazed

I checked out the Banski site today. I don't see that they are carrying the toe rods like they used to. I'd really hoped to change all the components out and use the same manufacturers stuff. Has anyone heard if they will be making these available in the future? I see that VB&P's carry all the components to completely change out the rear end. Does anybody have any knowledge comparing the two products (Banski vs VB&P)? Thanks! I'll probably call up Banski and inquire about the toe rods.

JrRifleCoach

Just a thought. Do you believe that two different vendors will use two different sources for the same part that's 20 plus years out of production? For a car that has limited popularity?

Most of what we need are either NOS or CE re-pops.
OTOH I have a used rear toe assembly (30K) waiting for a new owner.
PM for info. Shipping from kali.

JimZRyd

Well I certainly do believe different vendors use different sources to produce a similar or same product. My Moog ball joints certainly are higher quality than oem. Limited popularity??? Just how many C4's were produced and sold?

My 94 only has 10.5K miles at the moment, but I'm all for replacing certain expendable items with newer and more improved pieces. Thanks for your thoughts though

VBP and Banski's are 2 different takes on a similar idea as far as the shafts are concerned. VBP rod ends are screw in and locked into place with 1 or more jam nuts (assuming their product matches their pictures). Banski's uses cuts on the ends of the shafts and locking collars, similar in concept to collets used one lathes and mills. The locking collar is probably easier to tighten up without changing the setting as there is no radial motion like would be needed with a jam nut.

As far as the rod ends themselves, they could be the same parts from the same vendor or they may not be.

I would suspect either take would be pretty equal to the other in all actuality.

mtwoolford

went on Banski's site; noted that their products are also offered in a steel version rather than the aluminum rods; anyone use these or have thoughts on the steel versions ?

JrRifleCoach

... In the mean time look around and you'll see how few US vendors are making C4 parts in general.

Many timken bearings are now CE built, then repackaged here.
The US parts manufactures are gone.
And the C4 aftermarket parts are repackaged as well.
There are some high replacement parts like mufflers and shocks that have stayed on board.
But most are junk and sell for cheap.

Great example of the current state of affairs in our country, which ends tomorrow

To throw a third in the mix, there is also VanSteel trailing arms.

Are you guys that have switched, using the DRM relocation brackets too?
