IMHO PP vs non-PP is something unquantifiable with the available data - much like DCC.
If you choose another colour, you can see the difference, if you choose a panno roof, you can see the difference, etc etc
The PP and DCC are performance enhancing tech, but what do they actually give?
With the PP, you get more power, which is only a little, which offsets the extra weight gained from the diff. You get bigger brakes, but is it offset by the extra weight of the diff and the brakes themselves? What's the stopping distances compared?
I'd really like to see some actual driving performance hard data to make the choice.
Same with DCC, where are the numbers that show it makes any difference? We all know that the dynamic nature of DCC means that different settings make no difference to lap times, but show me the same for non-DCC.
I sometimes feel like PP and DCC are more about bragging rights than actual real world usability.
For 1k you could probably do a much better third party brake upgrade and tuning box, which gives you more than PP.
