You can easily reached upto 75% of this series without any gold upgrades. My car's PR is 47.2. I got 7 golds for 25%, 11 golds for 50% and 16 golds for 75% completion of series. You can get 24 golds for 100% completion pf series but it will require gold upgrades. You can easily collect 34 golds with only R$ upgrades or with 47 PR.

7 golds   - 25%

11 golds - 50%

16 golds - 75%

24 golds - 100%

Total 58 golds.

I think 49 PR is require for 100% completion of this series. I didn't unlock last tier.
