Hi, first post and an immediate question, today I started the tuning competition in the professional events category. I did the capri rally a few times for the 250.000 credits, and then after some hesitation i bought the Amuse Carbon R (R34) '04 I tuned it up to about 900 hp (could be less) and I started the cup, WITHOUT testing the car (I can be impatient sometimes) and what came to me is that the car's rear weels are continously struggling to get some grip when accelerating. I don't know wich tires are on there cause i left em standard (I think they're soft tires). So my question is: what can i do to get more grip?
