I feel the Z06 (out of the factory) has very mild/street based allignments and suspension settings compared to a factory RS. The RS comes with much more camber from the factory vs the Z06. So, with some knowledge and wrenching, I can easily add a significant improvement over the stock/street setting that the factory gives the car.
So, with some toe out in the front, a little toe in the rear, and about -.2.0 camber, lower the car about 1/2 to 3/4 inch, cornerweight the car on a set of scales, and even leave the stock run flats on, you could improve the Z06's lap times SIGNIFICANTLY without spending a dime.
You should probably go work for GM, since you know how to extract more out of the Z06 than the team of GM Engineers were able to when they posted their Ring time.
Again, the facts are the facts. A car with DOUBLE the displacement of the GT3RS, a car that has at least 250lb/ft more toruqe and 85 more HP and one that was modified by it's own engineers at a closed down, private session couldn't beat a stock GT3RS's time at a public, and damp Ring session.
This is hilarious.
OK, this test at Hockenhiem was different than the test at the ring. I WOULD imagine the engineers at the ring test, did adjust the car to it's best setting for that track, but this test was done by a car magazine with stock cars, not GM preppared vehicles.
Also, actually GM does use an OUTSIDE vendor to prepare their track cars in the SCCA Showroom Stock T1 racing classes where these cars compete against other stock GT3's and F360's. Pheonix racing (US based) is the #1 Corvette suspension tuner in the world, and has won the coveted T1 class (GT3, Viper, F360) since the Corvette was homoligated to compete. Phoenix (NOT GM) actually provided many of the specs for the T1 suspension packagfor the C5/6 that has been a popular upgrade for many Corvette track enthusiasts. So YES, outside vendors/people that have more experience racing the car on a daily basis, have proven records to extract every ounce of performance from the car vs the factory. This IS probably the difference between Porsche and GM.
And regarding the tires...GM Engineers have a lot more on their mind other than performance when making decisions regarding tires. Remember the Z06 has no place for a spare tire, so less than desirable run-flats were the only option for a car sold to US public. This was a compromise I am sure created many arguments internally.
People say WHAT IF the RS had 85 more HP...we'll I say what if I had the $35,000 difference in cost to modify the Z06? Your argument is NO better than mine! So I need 600 hp to decimate the RS..who cares? I still walk away with more than $25k in my pocket.
I think my opinion of the RS is coming accross all wrong...I think the RS is an awesome ride and the fact that the Z06 DOES need more HP to beat it, is a testament to Porsche engineering...BUT it's too expensive.
Many may not be familiar with me, but I actually RACE Corvette's. My car is a Phoenix preppared car. I am not a waxer, back mountain driver, or benchracer. I have been racing Corvette's for 6 years and have several time trial wins to my name. For a track car, price/perfomance is the last justifier, and after looking at several platforms (including EVO and such) I found that the Corvette had the most potential and significant aftermarket following that was centric to road racing for the $$$$ value.
Here is one of my video's...chasing a Factory Ferrari 355 Challenge Car. This car was preppared and sold by Ferrari specifically for the Challenge race seris. I personally have gotten my car so well set up, that I easily pass Viper's, 360's, 996 GT3's, and have the video's to prove it.
oh... and this is ONLY a C5 Z06.
