FM5 is really great, but if you don't know much about tuning, then you're f*cked, whereas in FH2 it's a little more forgiving. That being said, buying tunes doesn't work out for me, I like the fact that I have to put a lot of time into my cars to get the best results, separating the amateurs from the pros. I just need to get better at it.
It's actually quite simple once you get a good grasp on what your doing isn't it.
For me the most confusing things were the differential, gearing and damping (bump and rebound stiffness) but once I understood what they all meant I wondered how they ever confused me in the first place (keep in mind this was back in the days of Forza 3 so the basic tuning guideline may have changed).
I'm starting to get the hang of it to an extent. I can tune and upgrade a car to a point where it's average, one of the hardest things for me to get is handling where the car gets a decent launch and can exit a corner properly with AWD. I had AWD on a near-perfect Lamborghini Gallardo, and I say near-perfect because I had to brake so much and turn so sharply, that I had no speed exiting the turn and ended up losing positions.
Some cars just require good driving, like the Ford Falcon FG. Others, like the Mercedes 190E only seem to be able to either have speed or handling, where I'm getting beaten on every straight.
Maybe someday soon we can play together and you can give me some tips.
The hardest thing for me is damping since I can never get it on par with the suspension and diff settings.
It really comes down to how the car comes from the factory. If it's a heavy car with lots of torque or a lighter car with less torque, if it's got better or worse lateral G's and if the weight is distributed evenly or unevenly. I normally tend to go for the medium sized sports cars like the Skyline, Supra and NSX since I feel that they're easy to tune while being able to stay competitive in S class lobbies and higher. I just can't drive the Falcon, too much torque, keep in mind that I know when to feather the throttle when I need to but when I drive the Falcon I just feel that it has too much torque and not enough oversteer.
I would like to, I really would but I tend not to play online with people from forum sites, it's nothing personal I've just never been the type of person that plays online with people that I only know through websites.
For the record there is still something I don't get about differentials so I'm actually about to post a new topic (spam I know ) questioning how the Decel setting works in the game since I've been totally mindf*cked by the way Turn 10 explained it.
Trust me I know about playing with people online. I stopped doing that and only keep people I know in real life on my friends list. The only thing is that it's so hard to find lobbies in FM5 that aren't annoying kid ridden and dirty racers. I just want to join a club that does actual, precision racing with a good number of laps, and can actually fit my schedule.
That's why I barely play because playing offline gets stale with the same drivatars and events and dickhead people yelling over the mic make me turn the console off.
