Earlier tonight I tried to test the limit of the new set on a crossover on I-95. The best way to describe it is a long smooth two-lane on ramp. Approaching the ramp I punched it from around 70 and hit the middle over 100mph and then it starts to straighten out. I didn't even have to switch into the inside lane and honestly felt so in control and could have given it more. No slippage at all! I just justified my $2000 investment.
