That was my strategy. Unfortunately, I was also up against the clock. I only had a few hours to complete 7.4 through Stage 8. So, I went ahead with adding the 4th and 5th upgrades for Engine and Body, for the very reasons you stated. These are the only 2 which offered an additional R$ upgrade after the GC upgrade.

Turns out, I may not have needed all of those upgrades, but again, with my time constraints, I wasn't about to experiment with other options.

I passed 7.4 by the skin of my teeth (achieved 176.41mph vs. a goal of 176.40mph), though I think I was still at all 3's at that point, I don't fully recall. I do recall that it took me a lot of attempts, so I do think I started upgrading here, but may not have had the two additional R$ upgrades. I used ads to speed them up, but I waited out the last bit until the timer was below 30mins for the final ad. In the meantime, I'd continue to run attempts.

For 8.2, I did require several attempts, but I made much quicker progress after reviewing some of the comments here and going for the method laid out by a Random Fandom (currently near the bottom of pg. 2 of the comments), where he stated that you could use BA Low and run flat out on all corners except 3, 6, & 7. Once I trusted this method, I made it through much more quickly. On my winning attempt, I was actually a fair amount above the 112.5mph average requirement and I evens slowed a bit towards the finish to bring my average down a bit.
