NEED HELP! S1 2002 nissan slyline

My buddy and I play co-op campaign non stop and my favorite car is the nissan skyline. In fh2 I had two unbeatable cars that my buddy just absolutely despised. The Nissan skyline r34, and the McLaren p1 (awd conversion). He ended up making a 2002 nsx (awd conversion) that has amazing launch, top speeds that Im unable to reach for some reason and fair handling. Im stuck in a sticky situation because I try to go for grip 99% of the time. In this case I fear that Ill have to downgrade my tires and handling overall to achieve a higher top end with either a similar or slighty better acceleration. Ive tried tuning to the best of my knowledge. (Not a rocket scientist but still feel as though my tuning skills are acceptable) Will post the upgrade specs and tune specs so yall know what Im working with.
