You'll have to see for yourself. If you go with -1 T&W, that's 70 GC off the upgrades cost for the series (PR 80.0), so if the skip is below 70 GC, it would make some sense.

On the other hand, PR 80.8 should get you to 75% completion in the car's motorsports series, so you'll have to double-check if you don't miss out on the reward. Plus, if the car comes up in WTTT, you may find that additional upgrade useful...
