Obviously none of you guys have met or driven with Mike. While yes, of course the video is a pitch for his product, he is far more knowledgeable and credible than anyone in the GT3 forum. And probably one of the nicest guys around. Havent had the RS on track yet , but rear end feels a bit nervous. I've opted to go full soft in back and one from full stiff up front with the bars (similar to my '07 GT3 setup.) . But bars are personal preference and driving style, some like a loose car, some tight. Looser cars are slower around the track. There are plenty of GT3 drivers who prefer the "looser" setup. For some the car feels to "carve" the corners much better, which is probably true, but they are far from the limit of the car. Add another 5mph entry/exit speed and see what happens. His guestimates of lap time for VIR are probably spot on ... but for drivers of his caliber vs our.

There is no doubt Mike has talent and that he read the car correctly.
I am not 100% sure that his guestimation of Lap times were justified based on a quick squirt up the street, in particular on a bumpy road that looked liked it just survived the last earthquake.
Additionally, I feel that web forums are a great portal for information and that he shouldn't have mentioned this in his video.

I suppose you are always going to get quasi experts on every forum and obviously there are reasons why guys shunt these cars so much. which probably has alot to do with rubbish setups from these quasi experts.
I say. If you can't feel the setup change, then leave it alone. Because if you don't one day it is going to bite you in the backside.
Black/Red - A little unknown at this stage as I have never seen one, hopefully it looks good. If not, I will change the red to white gold.

Yes, the RS does have more front tire than GT3, but I'd rather start with a solid rear and a car that pushes and work from there. I suspect I will be adjusting bars all weekend.

I sometimes used mike on my last car, but his shop is a bit to far away to use vs another great shop a mile from my house Yes, the RS does have more front tire than GT3, but I'd rather start with a solid rear and a car that pushes and work from there. I suspect I will be adjusting bars all weekend.

By the way, what tyres will you be running?

I certainly am no expert at all:
I thought my '07GT3 was loose, apposed to others who think it pushes, so I guess my bad driving creates more oversteer then understeer.
I ran the rear sway bar full soft and the front middle and then it would start to push a little.
See fo yourself:
My fast lap in GT3 on cold day:

My fast lap in RS first day on the track very hot, 95F, did not find the limits yet, but I tried with abrubt inputs:
Bars one hole from full soft:

Thanks! (although I know your comment was 100% sarcastic)

Peter,
With your car set up like that, it is going to be very hard for you to ever find the true limits.
Your car needs more bite in the corners and more drive on the way out.
Next time you go to the track crank the bars both up to the middle and see if you can feel the difference.
Then try hard/hard.
I'd be really interested to hear what setup Chris Harris is going to be running at Ring with their stock RS.
Does anyone know?

No sarcasm from me.
These cars are very expensive and I know the first time that I take mine to the track I will be far more careful than in the Cup.

I'll be running 255/335 Hoosiers. Will let you know where I land with the swaybars, although pointless because there are so many other factors.

Chris Harris will run Slicks and different shocks/springs I heard, and on a smooth track, so that will be different.

Same here.
Because the RS feels much softer and I am wearing too much outside rear tire with even temps accross the tire, I am hopping to stiffen up as you suggested through the weekend. Leaving for Sebring tomorrow.

BTW are you running the suspension button in the cabin on?? Because on a bumpy track this might be too stiff?

The car is softer. It's not the sway bars.
I ran the GT3 in soft button, on hard it would bounce off the track, no matter how I set the sway bars.
The RS is soft enough with the button on hard, but I will try both settings once I start to start setting the sway bars stiffer. It may also be that I have the ride height higher on the RS (Stock).
think your car feels soft because you are running the sway bars too soft. You will be surpirsed at how the car reacts once you stiffen up the bars.

Sorry to tell you guy's (in response to their tire setups) but the 335's are hurting versus helping your performance and giving you more of a rear end "soft" rolly feel due to too much sidewall and rollover.. I learned the hard way, with different tire setups/widths and data logging...
I have some monster power in my GT2 and 315's in the rear with a good tire and setup puts ALL of the power down, you guy's might want to size it down on your GT3's especially if on just a 12" wide rim. It can give the appearance of a sloppy suspension setup
As for Levitas he definitely is seasoned and experienced, knows his stuff.. But take what he's saying in relation to what the car is.. It's STILL a STREET CAR, meant more so for the race track. He is comparing his GT3 Cups and racecars setups which have been worked on and perfected through countless time on the race track, you cannot really compare the two EVEN if it shares a few same components...
His advice is awesome, but not as relevant as we think. If you are turning the RS into a strict track car which sees no street time? Then it's golden indeed, but Porsche themselves didn't have that in mind when producing this car as much as the "RS" aura screams race car.. So yes it can be worked upon in his point of view, in mine and all of us who do most of our driving on the track and who like a properly setup track car... But for the majority of people that is not what they want..
