I have been an avid forza player since FORZA 2. In 2,3, and 4 i was pretty decent at tuning my own cars 100’s of hours in FORZA 4 but i can not dial in anything rally in this game. Would really like to keep the AERO bc i just like the look, all help is wanted and will greatly be appreciated. I usually get into the top 1-3% on most track’s but it seams that in FORZA 5 B & A CLASS really escape me. i spend between 2-4 hours a day on this game but just feel like im moving backwards on tuning. especially in mid engine cars i gave up on them altogether(for now).

Thanks to everyone who replies. i may not be able to get back on here until 8pm eastern to read info and replies but thanks to everyone.

ANYONE?

Are there any specific issues you are having with the car or do you just want it quicker?

when turning the suspension is very soft like marshmellows but any tuning i do doesnt help

what tracks did you run this tune on?
is there a reason for the clutch upgrade?
what driving assists did you use when driving this car?

only assist it normal steering

Take all of your engine upgrades off and add the race weight reduction.

Dump the roll cage as well.

If you can fit any engine upgrades back in after that start with the exhaust.

Cam upgrades should be the last one you ever put on.

Don’t use the clutch unless you have 1 or 2 PI left in the build and there is nothing else to add.

As far as your tune we are going to need to know what it does and does not do, but at first glance you should reverse your roll bar settings, I would drop your front spring pressure to about 50 lbs heavier than the rear.

Don’t use any toe in or out.

Raise your aero to max front and back.

Probably raise your rear decal up to 20-25%

I agree with Method mostly. I would also say take your brakes from 48% rear to 52% front. Never use the clutch unless your running auto or you have no other parts to put on the car.
