Hi Johnny,

1-Which setting do you recommend for track days, stock 06 Z51 with OEM Eagle F1 (currently) & track experience:

All On
Traction CTRL Off
Traction CTRL & Active Off
Competitive Mode - Which does what exactly? Manual is not clear, as it sounds JUST like Traction CNRL Off: "Competitive Driving Mode allows the driver to have full control of the
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!!

Hi Johnny,

I watched a TV show where you and Jimmy Johnson drove Factory Corvettes and the Corvette Race Car. Very Cool!!

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

I emailed one question in but here is another, not quite as on topic as my other but would only require a short answer:

John, now that you have quite a few races under your belt in the 2011 WC Series, what do you think of Mike Skeen. I really like this guy and what I've seen, he really rocks.

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.

Hey guys! Just testing out the new username. See you in a few minutes.

Johnny, please describe your ideal line (incl braking, trail braking) at Mid-Ohio.

Thanks!

Johnny,
As we all know, you have accomplished many things in your career, but my question is, what would you like to accomplish that you haven't already before you retire from your racing career?

Thanks for the comment about my commentary! I really want to get back to the ALMS, so hopefully this is a one year deal.

I'm glad you're enjoying the JO Package, I love it on my C5 as well.

Johnny O@PfadtRacing

Its hard to say if I'll get back in a Corvette, I certainly would like to for the longer events. The Corvette is the highest performance of the three cars but both the CTV-V and the Camaro are still a riot to drive.

What I like best about the Cadillac is that we get to do standing starts.

Hi Steve,

Why not just put the JO Package on your car and just be done with it?

All joking aside, I'm sure GM is aware of these issues.

-Johnny

Johnny O@PfadtRacing

This is a hard one to answer. Spring rate is more relevant to track conditions rather than the actual track. So as a driver, you need to know when you're driving based on your feel, whether you need more or less front a and rear spring.

I can't say you need a 400 front or 600 rear. A good place to start is to talk to guys that have run there before and ask how their cars are set up.

-Johnny

Johnny O@PfadtRacing

The beautiful thing about the Pfadt suspension is that it's adjustable. If the car is not behaving the way you wish at high speed, the first thing I would do is stiffen the front bar considerably. If you then find a lot of understeer in the car, begin stiffening the rear. But remember your settings for the track and the street will be different.

-Johnny

Johnny O@PfadtRacing

Thanks so much! My C5 has 108,000 miles on it and the the JO Package it is totally a killer athlete. Glad yours is, too.

-Johnny

Johnny O@PfadtRacing

We always use the same language whether its a race or testing. We describe the amount of understeer or oversteer through every aspect of the corner and as it relates to what we're doing with our feet.

The engineers will also look at all the data gathered to further improve the handling of the car. Honestly, there are too many things that the engineers look at to list them here.

Hey, Johnny, just dropped in to say 'hi'! :

VegasJen

This kind of reminds me of a question. With modern data acquisition, how much input do you guys as the driver really have? I would think that between you and Ron or Olivier or Jan, etc., you all have slightly different feels and styles. Do they tailor the car to each of you? Or set it up for whoever happens to be the hottest shoe on that track? Or just the way that pleases all the drivers equally?

Johnny O@PfadtRacing

If you're pleased with how the car handles now don't mess with it. But if you find the car has more understeer than you like, then I would lower the front.

Conversely, if it has too much oversteer, I would raise the front. Part of the challenge in racing is tuning your car, so don't be afraid to experiment.

-Johnny

Johnny O@PfadtRacing

That would be when the Aston Martin guys filled my exhaust with brake cleaner!!! And ten miles down the road I was spitting out smoke like blown turbo charger! This was at Petite in 2005. I'll never forget that.

If you ever want to do something fun that works.

Johnny O@PfadtRacing

How could I ever forget that? And I have no idea what will happen with the Jake Logo.

-Johnny

Johnny O@PfadtRacing

Actually it was developed for both street and track. It will naturally be a great improvement over stock suspension for autocross, but for that application I'd recommend you play with the bars. You will likely want the rear bar at full stiff.
