Yes sir. Since your bar isn't stock (24-30mm) just let us know the size of the bar after you order and we'll get you the correct brackets in the kit.

Last day for the Group Buy fellas:

Enter coupon code CorvetteForumGB at checkout and your price is $219! + actual shipping + tax (if your state requires us to add sales tax). The code is good through November 23rd, 2020.

If you haven't read our other reviews some of them can be viewed here on our website:
www.corvettecontrol.com. Of all the kits we've shipped, there haven't been ANY negative comments EVER! It does what it says it does and benefits all C4's regardless of mileage or condition. IMO if you own a C4 this kit should be on it.

- More stable at high speeds
- More stable over bumps, ruts, holes, etc
- Eliminates bump steer when cornering
- Eliminates groove tracking and the C4's natural darty behavior
- Increases on-center feel
- Removes steering wheel vibrations if they exist
- Does not remove any of the good analog feel/precision that we love about the C4
- Weighs only 5lbs
- Looks cool as heck!

So grab a kit and we hope that you'll help us spread the good word to other C4 owners.

I would like to add that if your front sway bar is not stock (24mm-30mm), and is larger than 30mm, you will need to email us after your order so that we can include the up-sized brackets.

Enjoy your C4 more!

I know this is getting kinda old. I bought and installed last November and just drove for the first time today, I agree with everything Dave said. Noticed the most on a bumpy interstate exit ramp. The wheel used to jump around when I hit these bumps while turning. Now it is rock solid. Bumps and wavey pavement in a straight line is also rock solid. I could not tell if the car was harder to steer -it feels just like I remember. The steering is very much improved and I am very happy I bought these. Could the sway bar clamps be designed to be easier to install--Yes. Should the sway bar clamp allen screws be a little beefier-Yes. Should sway bar locks be included with the kit-Yes. Bottom line-I like them!!! Dan

I am still recovering from orthopedic issues and haven't had a chance to work on a modification that would make these better. Back when I originally did the evaluation I was in line to have the meniscus repaired for the 2nd time in my right knee. That has been done and am dealing with some other issues (I got hurt 46 yrs ago, residual and ongoing problems). Once life gets
easier, I will go back and address the mods and see if they truly work. I have an extra set of brackets to experiment with.

I haven't been in contact with the vendor for a bit though due to my issues, not him.

Unfortunately it looks like he is a "former vendor" now.

However, here is his website, it is still up and running

I'll save my money then. I hope you were 'given' a kit to analyze and do a good right up.
The product is for C4s, why the "former vendor"? Maybe not selling like hotcakes

Did you not read through this whole thread ? This thread is the evaluation that I did with the set that was sent to me.

This site is a money making site first and foremost, you have to realize that. They charge folks to be a vendor, if you don't get enough sales, then the fee for being a vendor can be more than what you really make being a vendor. The owners of this site also own other enthusiast sites. They use these forums for multiple purposes.

1. to generate direct income from folks/businesses being vendors
2. selling advertising
3. not so much in older generations of whatever, but they do data mining for user fixes and sell that information back to OEM manufacturers. I caught onto that on an RV related site. I got suspicious of a poster and using my particular set of computer skills tracked him down and found out he actually was a member of the owner company.

I then read the company charter.

4. They also sell information to other companies (aftermarket). Depending on who it is that owns the forum, I am using the generic They (enthusiast forum owners as a whole)

This forum is not here just for your keyboarding pleasure.

Plus C4 owners are notoriously cheap for the most part.

I bought a kit from them outside the group buy. It’s one of the many fun “upgrades” going on the car. After the fairly impressive reviews, it’s worth it at under $200.

But hey, feel free to wait around and see if they make a 2.0 or something out of the suggestions the community gave. I will say that unprompted, a few weeks after I got my kit, they sent me a set of graphite inserts to improve the clamping force of the clamp parts. So their customer service leaves nothing to complain about.

How long ago did you purchase your kit?
I received the same inserts around the first of the year.

I did awhile back and why I asked if there's a chance at another group buy. I understand the business aspect of the forums, but if he can't afford to advertise or sponsor here(best C4 place), then how is he marketing them?

Maybe C4 owners are cheap, but that guy in Cleveland (Tom) that built the targa truss bars was very popular.
