I had already got gold on the first sector of the Circuit Experience for Kyoto Driving Park - Yamagiwa, so I finished that up today. Then I decided to get all golds on the Circuit Experience for Daytona, as well, which ended up netting me a four-star ticket. I felt so close to winning my first engine swap, but what I won was very nice, too: some titanium connecting rods for the Corvette (C7) ZR1, the first time I've won such a part. This marks my fourth special part overall, with the other three being two Stroke Up S parts for the Honda NSX Type R '02, and a Ultra-High-RPM Turbo for the Mazda RX-7 Spirit R '02.
Then, I tired my hand at the Gr.1 Prototype Series, starting with the ten-lap race at Daytona. (Go figure that the other major American motorsports event, the Indy 500, is also today.) I used the only Gr.1 car I had, the Audi R18 TDI '11, and despite using RH tires and placing the FM all the way on 6, I still had to pit at the halfway point - though I didn't need to change tires. Still, I only got P8. I wonder how I'd do if I changed to Racing Mediums, instead? It's amazing that Kokubun, true to his word, doesn't pit, despite driving a non-hybrid Group C Mazda 787B. Makes me think of changing to a different Gr.1 car, but I don't want to use the Mazda LM55 VGT, as everyone seems to be suggesting.
I then quickly got all gold for the Circuit Experience for Trial Mountain. Returning to the Gr.1 Prototype Series race at Daytona, I tried using Racing Mediums instead. Somehow, I ended up pitting at the end of lap 6 instead of lap 5 like I did last time, and this time, I did get a new set of RMs. But I actually ended up doing even worse, with a final position of 12th. Sure enough, it seems that the only AI driver to use the R18 '11 was in dead last, too. Makes me think of using an electric hybrid, rather than one based on diesel. Perhaps I'll try buying the newer yet more affordable 2016 iteration of the R18. Either way, a Gr.1 car that's both an electric hybrid and "only" costs 1m is likely in my future, and that'll be easy enough to get since I have over 6.2m.
Anyway, I decided to finish things up by making a very basic livery for my spare Toyota Tundra TRD Pro.
EDIT: The electric hybrid Gr.1 cars that cost 1m are as follows:
Audi VGT
Audi R18 '16
McLaren VGT
Nissan GT-R LM Nismo
Peugeot L750R Hybrid VGT
Toyota TS030
Toyota TS050
And then the hybrids which cost 3m are the Porsche 919 and the Toyota GR010. I mostly got the R18 TDI '11 for the trophy that requires that you take a photo of this car at Le Mans, within scapes. But what confuses me, is why are so many people recommending the Mazda LM55 VGT if it's not a hybrid? Won't you need to pit for fuel?
