Yeah, well my origonal idea was bettered by an idea that my team-mate HMSMotorsport said ... To use premium Clio, later on that week I and others realised they weren't as fun and that we should use Racing soft tires. So many/all previous posts here about it are out of date.
Premium Clio
Racing Soft/Any tire you want (makes no difference, any other tire is slower)
Mod it however you like
BUT
Limit it to 500pp
That's final as well, will not be changing.
Sorry for confusion
Gotta get it right before it starts, had great fun yesterday with them, pretty much a photo finish across the line, side by side around last corner xD
