I just installed it today on my '08 Z06. Was somewhat confusing, but I figured it out. The minimal testing I did on Street tires was dramatic.

Looking forward to next weekend's competition. I'll report back with the results.

Nice, one of my buddies is installing a Pfadt SS package on his 03 Z06 and I helped him do the front bar the other day, stuff looks top notch

What handling issue are you trying to address with it?

Probably the same thing every Corvette driver is trying to correct with a front bar...corner exit on-throttle oversteer.

C6400hp

wont you be giving up corner entry to get that?

TedDBere

Depends on your front grip and how much bar you add.

I'm sure he's added camber and sticky, wider, tires so he can get away with a little bigger bar. Maybe a little toe-out too.

I want the car to turn like it's on rails. The shocks made an improvement. Since the sway bar can be changed and still allow the car to remain stock, I chose to make the investment.

From the initial feel of driving on the street, I think my speeds in the slalom will increase some.

I've had some seat time in a C5 Z06 that has won Super Stock here for several years and his car "felt" way better than mine, even though my car is now faster. He had the full shock / sway bar swap out done. I'm really pleased with Pfadt so far. It's not a huge investment. I just need to beat these last three guys. Clicky None of them are stock.

I think mine will finally feel very close to his, hopefully giving me the confidence and ability to go even faster.

I'll know on Saturday if the change made any difference. We have the same 1/2 mile test-n-tune course that stays the same every month for just such a purpose.

Yes:

I have all of that, -2.4 camber, 295/345 wide Hoosiers front/back, and a little toe out in the front and toe-in in the rear.

The other thing about the bar is that it's Adjustable. I can soften it up more if I want.

I "have been told" by two multi year national SCCA champs that adding a bigger bar AND CHANGING NOTHING ELSE will result in more understeer (push) - not what you want to accomplish.

Having said that, I tried a bigger front bar and it "seemed" like I could turn in better,

however

it also seemed to "plant" the rear end so I could not rotate (oversteer) the car.

I may go back to the stock bar and try fixing the driver next. Fixing the driver will basically mean turning in EARLIER and trying to backside the slalom cones. I think if you turn in earlier you are asking the car to "do less" turning & it'll upset suspension less & faster slalom times will result.

If you have a fixed T&T slalom available you should be able to figure out the best bar for your car in short order. Same day same ambients, same tires & pressure etc. I don't have that where I am so I go from event to event (different courses) which makes it much harder.

Let us know in terms as objective as possible how it comes out. Good luck.

Please keep us posted. If you are like me you can use as much help as possible going faster.

Looks sweet. I love seeing photos of our stuff on people's cars. I'll be interested in your impressions on the AX course.

The relative rate of the front and rear swaybars will determine the amount of weight transfer to the outside front and outside rear wheels relatively speaking (there are many other factors in that equation, but not that can be modified quite as easily as a swaybar change or adjustment).

A stiffer front bar will transfer more load to the outside front tire. Through the complex grip versus vertical tire load relationship, that will in most cases give more grip to the rear end allowing more power application which (as TedDBere stated) is the problem that most C6Z owners are trying to solve on the auto-X course. Will the front grip suffer? Maybe, but not necessarily. It depends on significantly on where in the load curve that tire is. If the front tire is already past its peak load to grip relationship, than overall grip might reduce. That is not really important, what is important is that the car now displays better balance and allows higher cornering speeds and better corner exit power application.

I keep a log of my car changes and times on the test course. I'll know pretty quickly how the bar impacts my times. I've run the same course for 18 months, so my times from lap-to-lap typically vary by only 2-3 tenths.

Aaron,

BTW, Steve Burger is one of mentors. He tells me he spent time with you on the phone, I think on sway bars, awhile back trying to dial his car in. He speaks highly of you guys.

looks kewl
you will luv the bar
