At least with my comfort level anyways.

My neighbor's AMG GT-C by comparison has over 100+ more hp/torque and barely even breaks a sweat under WOT. It's a much more expensive car, but software is something that even Americans in their 40k Mustangs and Camaros get right. No excuses in my opinion. Just hope Lexus gets it right with this one.
Are you talking about on the twisties or WOT traction? I have no issues with Michelin SS on stock tune, stage 1, and stage 2 tune. I started having minor slippage with E30 ~530WHP and a lot of traction issues with full E85 ~600WHP.

Have you considered having Euro MDM coded? I heard it is a big difference from stock MDM.
