I'm tired of the shitty traction offered by the stock Michelin runflats. I want to upgrade and most say to go with the PS2's. I have heard both positive and negative reviews on the Nitto Invo. I like the much more reasonable price of the Invo's, however, I want more feedback of\n these tires from other Viper owners. I've seen a set of Invo's going from $1100-$1200, but the PS2's I can't find for less than $1600. Are the PS2's worth the extra $400-$500 over the Nitto Invo's? As far as I know, these are the only thread matching sets available to replace the stock tires.I already saw the 9 second pass from the turbo coupe with the Invo's so please don't post it. Can anyone provide some feedback on the Invo's? Thanks
