Interested if anyone has installed the Vansteel coil overs for front, rear or both. Whats your opinions ? Thinking about going to this set-up for a track car.

 

I am prepared to make this mod also soooooo

 

Try posting in C2. JohnZ has worked on a project with them.
I don't think he looks at this section.

 

I've sold about 15 kits so far but I haven't had any feed back yet. I'm guessing project cars and cars are starting to go to storage and getting work done. Some just don't call back either to give feed back.

 

I should be installing my rear kit in the next few weeks..already have the meyer front conversion.

I have a set of the fronts. I cant really give much in the way of feedback since my car is in pieces still. I will say they look well made and are very attractive

 

I have a complete van steel front end on my 68, control arms and coilover shocks. It all went together nicely had to do some grinding on the upper spring seats for the coilovers to clear.

 

I'm an expert on front and rear suspension install.
Send me a free "test" package and I'll give you some detailed feedback within 24 hours of being visited by the brown truck.

where's your xmas spirit????
Ricky Bobbi says baby jesus would agree with me


Currently I have the VBP perf plus suspension package but would consider coilovers on all four corners in the future after a paint job and 6spd.

 

I am going to be track testing my QA-1 dual adjust coil overs as soon as I get my 13 inch disk setup with air ducting done. The front tires will be 295/17 R-6's

I'm doing the testing for two other c-3's so they don't have to be changing springs or purchase other parts.

What kind of brakes and motor do you have?

I'm already prepared to listen...


I'll be interested in seen a hard track test of these kits, so pls hurry up

 

Don't you have the semi-coilovers though? You will notice a difference over stock. I most certainly did when I had them in. Your going to have to play around with the setting for awhile since you have the doubles with 576 different options.

Dedicated track cars really shouldn't use QA1's imo. They are good for guys that like to go out every once-in-a-while and for street guys.

Difference between semi-coilover and true coilovers.(I know, I need better pics )

At some point you have to make some cost decisions. My problem was my fenders were touching down on the sidewall of my 11X25 goodyear slicks on uneven pavement on the track when braking. So I had exceeded my 550 coil springs and shock setup. I really considered 700# or 800#, but then you are stuck again on one setting. If I'm at the track now and I touch down on the tires. I can roar into the pits and make a compression or ride height adjustment very quick. Anyway i figured that I will run my stock A-arms until they get smashed up.

I also went with Semi-coilovers to save about $500 over your $1300 kit. My front brakes, QA-1's, front tire setup was already over $4000.

You guys would be a cut above the competion if you offered all the spring rates instead of those multi weight SB a BBC coil springs

 

I totally agree with you on cost and it is VERY understandable.

I'm not sure what you were told when you purchased the semi-coilovers from whoever you purchased them from but QA1 only offers 3 springs for those, 350's 450's & 550's. I offer all 3 all though I only list 2. The 550's are a special order as I don't stock them but are available. When we 1st start development w/QA1 they only offered the 2 rates which are on the site and it will be updated shortly.

We will be working with Hyperco to have more spring rates available for the semi-coilovers. QA1 used to use variable rates but have changed to linear rates which I want to go back to with the help of Hyperco. For true coilovers I have them listed the same way BUT again there are different rates that can be used. You just have to call and ask. There are a total of 22 rates. That would probably confuse most and is why we just baseline. However, I will, if there is a way to put something on the site that mentions custom rates and to call. I'm glad you said something about it, thanks.

QA1 is hard to work with on some things. You'll also find that the spring is a 1/4" to skinny on the top(1/8" on each side) and I can't get them to make that change either. You shouldn't have any problems on the install b/c once they are in they won't move but a "perfect fit" would be great from the start.

Feedback is always good and I'll be waiting hear your results.

 

OK, now I'm a little confused. I'm looking at the pictures, but please someone describe the difference between semi-coilovers and coil overs.
Maybe you could get one of the three big Vette mags to do a conversion with before and after data and perspectives. What does going to coil over suspensions do for your ride, handling, and weight? Front and back. Maybe some skidpad and slalom tests too. They can use my car if they want. My 79 has stock type front with Bilstein shocks and stock type rear with a glass spring and Bilsteins and the biggest sway bars I could buy back in the day, and 275 17" and 18" tires. I'm one of those good guys that drives hard on the street and canyon roads, but will take it to the track maybe twice a year. Should I do this?

 

Let me get this right, on the semi-coilovers the bottom of the spring is supported by the spring retainer and the two screw mounts on the shock to the underside of the A-arm? That seems like alot of stress to those two little screws! It seems like the best way to go is with the full coilover regardless of how many options there are with rate adjustments. I would be nervous about the screws coming out with all that pressure from the weight of the car and the spring.

 

semi coilover, fits in place of your standard shock absorber and spring. The shock has a bottom mount for the coil spring, but the top mounts in the standard spring pocket in the chassis.

True coil over (along with custom upper and lower a arms) Means the shock has both the top and bottom spring mounts.

I added somethings to my upper post. I called VB&P. I did not get good answers about semi-coil overs. They were also selling the multi-rate spring sets. So I called QA-1 to get REAL information.

They sell 250/350/450/550# and with a little research each pound rating corrosponds to the weight of the front of your vehicle. Like 350# might be for 1600-1800 pound front ends. So a car that is true 50-50 weight bias and 3400 pounds like a Vette would need the 350# set. Don't quote me on the numbers because I don't have the sheet in front of me.

Then you have to bring in the type of front tires you have as to the amount of weight x-fer. 11X25 slicks and stomping on the brakes really slows you down where a 245/50/15 might only generate 1/2 the weight x-fer. So I bought two # sets for testing

 

OK, thanks. Now I see the difference.

No the shock does not get mounted like stock shocks do. These mount to the top side. You can remove the 2 nuts or drill them out. If your pockets are looking ruff, I would recommend making a plate and welding it in, buy new stock lower a-arms or buy tubular lower a-arms.

 

Oh, Ok. that's better. Thanks for clearing that one up. Although if I wanted to do coilovers I would be getting the full system.....Way coool!!!!
