Coilovers for C6
Stay safe out there!
We have done all the testing on our own LG Coil over shock package. I did the track testing my self until we arrived at what I thought was the optimum set up.
We then got Bilstein to custom build us our own Aluminum shock bodies and they install our proprietary valving to make the best coil over package for the Corvette C6 or C5 that there is.
We also make our own upper and lower mounts to make this a complete bolt in package. we use Spherical bearings that are teflon lined for quiet operation while not allowing any deflection that a rubber connection would have.
The shocks are the same shocks that I use on our Race Winning World Challenge C6 that we won Sears Point, Portland, Mid Ohio, and Utah with. I think that they would clearly be "track tested".
Our LG Coil Over package is a road race set up, it is not a drag package.
We use only HyperCoil springs which are the only spring to win at Indy, Formula one and Nascar. They do not take a set. meaning that once you install them and set your corner weights, they do not change. We have used cheaper springs in the past only to have them change installed height. Hyper Coils stay where they start from day one forward.
Our Bilstein shock package also allows the shocks to be mounted upside down, so they reduce "Unsprung weight". The heavy end is mounted to the chassis, not the suspension.
We just got a batch of our custom shocks in from Bilstein, so we can ship immediately.
You will not find any shock/coil over package that has been validated and tested like ours. We compete on the World Challenge circut against all the high priced packages and beat them.
We don't build anything for a road race Corvette that I would not take to the track myself. The saying ,"We race...You Win" is true.

Note, the lower front mount has long since been changed from this one shown.


First our spring rates are designed for the enthusiast. We know that the factory didn't put enough rate in these cars, even the amazing C6Z is a bit soft on the track. We stiffen up the car but at the same time we keep an eye on what people do with these cars. My customers will drive their cars on the weekend, to work, in HPDEs, in NASA races, NHRA races, and in the One Lap of America. The car needs to have a spring rate that accommodates all of those things.
The second advantage our coil over kit has is that the damping is adjustable. That allows the user to tune the damping for his/her car. 15 out of my 16 settings probably are wrong for any particular car, but every car is different. We all have different tires, different roads, different sway bars and different driving styles. Those 16 settings on the damping allow you set up your car for your conditions.
The third advantage of the Pfadt coil overs is that they allow a huge range of ride height adjustment. Our shocks are unique in that they are built with adjustable length bodies. With that you can set the sag of the suspension which keeps you in the middle of your suspension travel and then adjust you ride height. Our coil over kit allows you to run your car at stock ride height or with the tires tucked into the fenders without bottoming out the suspension. That keeps the ride quality great even if your car is slammed.
We had a lot of options when we were designing our coil overs. We chose a steel monotube design because of its strength, reliability and simplicity and because if needed it is rebuildable. Our front shocks were engineered with a polyurethane top bushing to help reduce some of the noise and vibration transmitted from the tires to the chassis. Our rear shock features a spherical bearing on the top and retains the factory bushing in the lower control arm, like all coil overs on the market today.
I also spent a tremendous amount of time testing our package – both on the track and on the street. The track is where we do our testing because it is the only place to push the car to the limits and measure the performance of the suspension. But most of our cars also get driven and tested on the street because our suspension needs to be effective there, too.
Coil overs are a great upgrade for a C6 Corvette. They are a one-step solution to the factory spring and damping short-comings.
There are a lot of good choices, just buy something
Without turning this into a "shock war" I will point out that we chose aluminum bodies precisely because of the weight. And we chose gas pressurized also precisely because we could mount them upside down (heavy side up).
To minimize these key points is not telling the whole story. It is very important.
And the upper mounting method that we use on our Rear shocks is far superior and actually the only way to go to eliminate the friction and spring deflection that occurs with the other method. As the shock goes through its travel, it travels in an arc as does the bottom of the spring so the spring is forced to bend in a "C" shape. That is why we went away from the old Camaro spring mounting method.
Force=mass x Acceleration and the force in a shock is the dampening power and the mass is just that. The mass is the mass of the shock, plus the suspension, wheel tire and everything. if the mass is reduced then the shock can control it easier. That means that is the mass of the shock is increased then it too has to be controlled which reduces the effectiveness of the shock.
One of our LG/Bilstein shocks weighs exactly 2.2 pounds. Compare that to the other brands. That is the shock only that weighs 2.2 pounds. The majority of the weight is the shock body, with the fluid weight. Now take that heavy shock body and attach it to the A arm and you now have that weight added to the A arm rather than the chassis. So by percentage of the weight of the suspension, you have added a significant amount of weight to control That is why it is important to first use Aluminum shock bodies, and more so to mount them with the heavy side bolted to the chassis not the A arm.
None of it matters until you hit a bump and the suspension is pushed up at some rate. but when that happens, I want a lighter suspension to control.
It would be interesting to know the weight of all the other brands of coil over shocks.
Having a few people buy another brand does not bother me. But having a few people post up that the LG package is inferior when in fact it is superior does bother me.
We rarely leave anything on the table when we build a new part. We always take into consideration all the things that I have come up against over my 35 years of racing experience. If I was not winning and running up front all these years, you all would have no reason to believe me.
But the fact that we have regularly won races, to the point that they make rules against me is testimony to our technical ability.
Make an informed choice before you buy a coil over package. Just because it is a shock with a coil spring around it doesn't make it good. It just makes it a "coil over" by definition. If you want a good street shock/spring package, stick with your shock package.
By the same token, a "New" package is not necessarily better, it is just new.
We built our package just the way we did for a reason. In fact we did it for many reasons. none of those reasons was "drag racing" so if you want to drag race, LG Coil Over shocks are NOT for you. BUt if you want the best handling, best performing best thought out coil over package that money can buy, then the LG package is the right answer for you.
See you at the races.
