New to Fora Horizon 2 need help please

Hey everyone I just bought horizon 2 for xbox one and I really need help. Before I go into detail let me explain that I have no knowledge when it comes to cars what’s so ever. So I will be explaining everything with my current car in detail. Before I do just wanna mention that I have ABS Brakes on through the settings as well as traction control (ON) and Stability is off ( I want to get 20% extra credits) and my difficulty is medium. I will be going first through my car in details far as parts than I will explain the tuning aspect of it.

Can’t control car is slides to much any suggestions

Try increasing the differential for each setting. That’s usually a quick fix for wheelspin.
Also, try and downgrade the weight reduction. An overpowered car with an excessively light frame is hard to control, since it might not have enough weight keeping it on the ground.

…Your problem maybe that you took a ferrari and made it awd…;).not really iv got a couple myself but the challenge stradale is great rwd in s1 and really shuldnt give you alot of wheel spin…build the handling up to 8.3/4 which puts accel at about 8.8…this cars good for handling so dont worry bout it being low powered…most of this game favors handling over spd anyhow…maybe try lower psi on back tires and a differential set at about 20-40/10…and dont listen to that stuff about everything needing to be awd thats nonsense especially for lower classes as in under s1 …or download one from storefront theres quite afew good ones;)
