Racing Intermediate tires, makes for no hassle races. Easily won all 3, with Spa being a blowout, and having most of the field a lap down.
Here's what I used...
Suzuka..........Honda Weider..595pp
Nurb...............HKS CT230R..600pp
Spa.................R35 TC........681pp
No bonus for using less PP, that's just the way the cars worked out.
Also, tried the Lambo Mercy largo super leggy whatchamacallit at Nurb, but it was just way too unruly. If you want to simulate no SFR, that's the car to use.
