Re: MOTOROLA CUP: Vette\'s R like Gore >> need an unfair advantage to win...>
i've been making the wheels for most of the teams in what is now called motorola cup (its been ****** challenge, firehawk, toyo street stock endurance, and speedvision cup, before speedvision switched it's sponsorship to scca world challenge and now toyo is the tire for that series, go figure) since the 1995 season. like the viper days, i get fairly involved with the teams i work with, and spend a lot (ask my wife, she says to much) time at the track. since tire and wheel packages have such a tremendous effect on the performance of a racecar, especailly in an endurance series(m/cup is on hoosiers, and sizes are specified
at the begining of the season and can be changed if deemed necessary by the tech director, but motorola cup doesn't specify rim width, only track width, which gives me the opportunity to work up wheel sizes/fittments that can give a team more performance and longevity out of the tire speced to them)
at the beginning of the season i was asked which tire packages would be best for the corvette and the viper and a few other cars. the viper was to weight 3400lbs (vette 3100 ish) and was to run a stock output engine the (vette had a package based on the asa engines, around 450hp), also both the viper and the vette were to have the same brake package (a 14" bear/alcon six piston or brembo monobloc front and front on the rear, the brembo had some significant advantages like it uses a much thicker pad, but is so large it would protrude past the fender on the vette, but gm approved it anyway) based on the weight the viper was to carry i recomended the 305 30 18 (dodge wanted the 18's, but it pretty much what we use on the viper days cars) to get the car to stop, i got hoosier to produce a 285 30 18 for the front of the vette (that about as big a tire as the bodywork can handle and you would need an 18 to get past the brakes that gm approved for the car) only to get shot down by gm, who wanted the car to run 275 40 17's, like they run in world challenge/t-1 (completely ignoring that in world challenge/t-1 the viper was limited to that size tire, but in m/cup it was going to be running a much larger front tire, and the fact that the tire, and necessary wheel, package wasn't going to clear the brakes they were planning on using). i screamed and yelled that they were going to get thier heads handed to them, but in reality, gm didnt realized how bad thier underestimation of the viper's potential was untill it was too late. this coupled with a tech director that was only to willing to give the viper team even more than what was originally spec'd, led to a situation where the viper could win any race it chose to. it's performance at mid ohio (close enought to the front to keep the points lead strong but not close enough to appear that the added weight was justified) was tanamount to playing possum in order to get the weight taked back off, and it was the next race. varde knows how to play the game as well any anybody, he couldn't have asked for a better set of circumstances.
