Yesterday tested the Parma Alfa 156 on my RRR and not surprisingly it has straight line stability,speed and it's reactive to inputs,pretty much like a real Alfa Romeo.The bad side is too much straight line stability so steering suffered,maybe it was because the track surface didn't offered much traction but this body will be reserved to low traction surfaces.I keep hearing about the Blitz and had one Alfa 156 from them felt like this one so next year I'll try the altis and rs4.
Allrounder?Hmmm...Stratus?Had the team magic one and felt like the Parma 156 with more drag and less reactive.
