On another forum (bikes) various vendors market "packages" of upgrades offering various selections of goodies aimed at providing different performance outputs.

It seems to me that some of the upgrades being variously selected at random by Z owners are neither sympathetic to one another or even worth the investment.

Somebody make available a TESTED series of packages for, say,
25kw
50kw
75kw etc and so-on
for a balanced selection and packaged price.

Less wasted money - better bang for buck

Marketing opportunity.
