1. Is it a waste of time trying to lauch my viper putting down a measily 600 rwhp right now without installing some unitrax shafts first.
2. what is the ideal tire pressure range to inflate these slicks to. never tried running full out slick before, only drag radials.
Actually the E.T. Street tires are a little more forgiving that a drag radial because the sidewall has more flexibility. I'd start out at about 14psi which should be close. If you launch the car hard enough chances are you will break a halfshaft though.
