I still don't know what car works bets for me

I have done 20 or so laps with the Denso Supra, and got a certain time that took me a while and some effort to get...
Then I hopped in the Castrol Supra, and I was consistantly lapping close to that time, and then got one lap 0.700 faster

Unluckily I put more than two tires off the track for a fraction of a second, and that ruined it...
So I hopped again in the Denso Supra, and I could not get any better than the time I already had with it - while, on the other hand, with the Castrol Supra I could flucutate constantly anywhere from 0.200 seconds above and below that lap time...
Maybe, I should just drop my prejudice against the Castrol Supra and drop the Denso Supra for this week... It seems that the Castrol is more forgiving, at least for me - namely, even if it can't take the corners as fast as the Denso, it makes up for that difference in the handful of straights and in acceleration...
We'll see what unfolds later
