Hey Johnny,
If you could pick any car/team, other than Corvette of course , to race with, which would it be?
Have you ever raced an LMP, IRL, or F1 car and how does it compare to other cars you've driven?

Default Shocks or coilovers

Hi Johnny,
I've got an '05 Vert that I've supercharged and headered and now I want to improve the suspension. I noticed in your Stage 1 package that you use shocks. Would coilovers be overkill or something I might want to go ahead and do now? It's a weekend use street car only, but I love to drive it "spiritedly". Cost is not much of a problem, just don't want to have to do it twice. What's your recommendation? Thanks for your time.

After you retire, will you keep your own dedicated track car just for fun? If you did tomorrow, what would that car be?

Great question! I spent two days with the engineers at Pfadt out at Miller Motorsports Park, helping and developing testing the shocks and sway bars. This was in a car that they purchased specifically for this test.

I was extremely involved and specific in what I wanted in the product and am glad that it came out exactly as I intended.

Take a look at the video we did showing the test sessions.

I miss seeing me behind the wheel of C6R too!

Seeing that the z06 and gs share the same sways and tire size, what was the reason for choosing the z51 spring rates for the wide bodied grand sport? Also would the GS shock setup be better on a z51/base model instead of using shocks from the z06?

The zr1 is rumored to use softer springs than the z06 - is this true and do #s exist for the C6 tinkerers out here who like to dial in the suspension a little further?

Finally, the alignment settings - do you have some general personal preferences?


I have been trying to study/ test as much of the suspension as possible to get the best understanding of the dynamics of the platform so any and all input is much appreciated!

Thank you!
Those questions would be better asked of Jim Mero. In my development work with GM I would give suggestions and tell them 'better' or 'worse' but they are the ones to make the final decisions on how the vehicles are most likely to be used.

I have always preferred a manual. I think technology is great but sadly in my opinion, it has taken away from the athleticism needed to be a driver.

Drew,

Nothing specific comes to mind but I knew that if I stuck with it good things were sure to happen. Quitting was never an option.

Thanks & you are doing well as a commentator, keep it up.

Why do you think I moved over to CTS-V? The Recaro seats over there are bitchin'!

I agree with you on the seats, but sadly they don't listen to me on everything.

rear wheels while the Active Handling System helps maintain directional control of the vehicle by selective brake application. The instrument cluster light will not be on. The
Traction Control System will not be operating. Adjust your driving accordingly".

Is there no: Active Off - leaving on Traction CNRL option?

2-And Alignment recommendations (question has been asked). Better yet, a SoCal suspension tuning shop recommendation to install your kit & align properly?

THANKS!!
-Eric
This would be based on your own skill level. When I'm running, I turn everything off, but its never my car and if I wreck I never pay.

So the choice is yours. The safest position for track days would be competitive mode.

Look to Pfadt for these alignment specs. They have a good set up sheet.

Couple of Questions

1. Do you follow Nascar and if so how would you rate the difficulty of a stock car versus other forms of racing?

2. Have you Ever considered driving in any of the Nascar series like a Max Papis or Ron Fellows?

3. Since Joining the GT2 Class are we (Chevrolet) keeping up with Ferrari and other Manufacturers to give Team Corvette the best equipment?

Thanks for your time
1) I do follow NASCAR and obviously the car is extremely difficult to drive and those guys are ALL great drivers

2) Yes I have but sadly the opportunity has never presented itself

3) Yes the team is doing a great job! And are certainly getting the best that Chevrolet has right now. GT2 is perhaps the most competitive series in the world right now.

PS: I talked with your good luck charm (the tall blonde Cadillac Flag Girl) at Mid Ohio. She is really awesome and knows her stuff. She sure seemed to help with your luck at Mid-Ohio.
Mike is a really great guy and a great driver. He is certainly doing an awesome job in that Corvette.

My ideal line at Mid Ohio is the fastest one! Come see me next year when we're racing there.

What does GM think about the Corvette beating your Cadillac isn't that the old #28 Corvette?

Drivers still have a TON of input as we're the ones driving the car, not the computer. But a great question is that compromises are always being made between what the data says and what the driver says. Remember, to be fast, all the drivers have to be happy.

Mike G writes via email:


Hi Pfadt,

I have the entire Pfadt system on my 02 Z street/track car.

(my tracks = med speed road courses in So Cal... no rovals)

My Pfadt suspension was adjusted as Pfadt suggested and works very well on track and street.

My question is I just changed my 3.42 gear to a 4.10. (460 rwhp/420tq…R rated tires w/added camber)

Now on the street the car transfers much more weight on and off throttle.

I have not had it to the track yet with the 4.10.

I changed gears as the car was too floaty off throttle with the 3.42.

I thought the 4.10 would help transfer weight to the front to help my turn in when off throttle.

At the time the car was neutral so I did not want to change sway bar settings to improve turn in off throttle.

Typically what should I expect and how can I tune the Pfadt double adjustable shocks to take advantage of the 4.10?

Increase front shock rebound or add compression to the rear?

Car has Pfadt coil overs, Pfadt double adj shocks, and Pfadt ady sway bars.

Thank you,

Mike in San Diego

PS I was really impressed with Johnny’s comments on his recent ALMS TV broadcast.

I hope you enjoyed it and will return to TV race coverage when you are not racing.


Of course there are ways to improve your suspension to change your initial throttle off turn in! Your best bet is going to call Pfadt direct because they are intimately familiar with their damper curves on their new coilovers. Generally speaking it is best to tune with compression primarily. But they will have a more specific answer for your set up.

Thank you so much for the comments on my commentary! I love doing it.

Hey Johnny,

How did you come to be a factory driver? Most pro drivers bounce around from team to team with mediocre success, but most factory drivers seem to stay put and are racing on a very consistent basis. Another factory driver (of a different manufacturer) told me it's the best place to be.
