Of course you can. My car is 5-5-3-5/4-3-5-3 and I'm at test 31/Lab 3 with 6 days to go. I haven't used any tokens, and I still have plenty of R&D boxes to obtain. I need at least/only one more i6 engine to pro the tire part of the car. Btw, I used 4 free upgrades from the R&D and 2 free upgrades from an Apex Wed. Cup. I will be able to max my car just by getting 2 more free upgrades from Mastery, but I'll see if it is necessary.
