Running ABS. I am using Viper suspension, brakes, wheels & tires. I'll be a bit heavier than the Viper and weight bias will be more to the front but I'm working on that. By using Viper wheels and tires the algorithms work even though the weight and distribution will be different, according to my research and the techs I've spoken with. The Gen 2 didn't have ABS until real late in the gen and the Gen 3 ABS can be operated without the computer. Should work out well, but before I take the car on the street I'll be sure to get to a track and do some testing, HARD!
