'''Proofs:

1. A car with a large TK bonus will end up at roughly the same speed as a car with a smaller TK bonus but an equally (inverted) higher rank.''' The Camaro Z/28 has a MAX + PRO rank of 1309 and a TK bonus of 87 (total=1396), while the Renault DeZir has a MAX + PRO rank of 1262 and TK bonus of 128 (total=1390). Both have an identical total top speed of 361.5 km/h.

2. Most (if not all) of the rank is decided by total top speed alone when a Tuning Kit is applied, despite acceleration and handling upgrades giving rank from default to MAX + PRO. The Renault CLIO R.S. 200 EDC and Volkswagen Beetle Turbo start off with an equal Acceleration stat of 3.62 seconds, at ranks 1202 and 1230, respectively. With a TK bonus of 54, the CLIO increases to rank 1256, while the Beetle's 84 TK bonus brings it up to rank 1314. Surprisingly (or unsurprisingly, based on my rules) the two cars end up with, again, identical acceleration stats of 3.13 seconds (you'd think a larger TK bonus would result in a better Acceleration, but clearly not). This shows how the Aceleration doesn't affect the rank a lot or at all.

3. TK bonuses are your MAX upgrades + 1 level, with PRO upgrades + 0 levels. This one's super simple. Just look in your upgrades section of any given car (not fully MAXed) and notice the green part telling you what the stats will be after performing the next MAX upgrade. Turn on a Tuning Kit, and this increase will always (based on cars I've tested so far) show the exact same increase. The proof where PRO upgrades don't matter is that the MAX upgrades only displays the MAX increases themselves and not the PRO increases. Since the MAX predictions always match the Tuning Kit buffs, regardless of PRO upgrades, we can assume that PRO upgrades don't affect the Tuning Kit at all. This proof also shows how the rank difference between default and MAX is directly linked to the TK bonus size.
