Does no one who edits these pages actually understand how the Tuning Kit works?

A low Tuning Kit bonus is a DIRECT RESULT of having a high starting rank.

Tuning Kit bonuses are based on MAX upgrades (the next MAX upgrade for each level, sans PRO upgrade increases) so the cars with bigger gaps between their upgrades have better Tuning Kit impacts. A car which goes from (for example) 200 km/h to 250 km/h MAX raw top speed will have a Tuning Kit bonus putting it at around 265 km/h; meanwhile, a car which goes from 235 km/h to 250 km/h will have a measly Tuning Kit bonus putting it at around 255 km/h (if you add around 1/3 of the speed increase on both cars).
