Indeed. And Rental + Homologation changes things around quite a bit. It boosts cars like the Corvette and nerfs cars like the 458.
And it limits the M6, which can be homologated into Forza GT with both GTLM and GT3 builds (that's right, you can either open up restrictors or add wider tires, nice touch from Turn 10).
One thing is certain, though: even with such restrictions, the Z4 won't stand a chance. No top end in that.
May the forced induction be with you.
