Notes :
Ferrari F40, the last great Ferrari IMO, no electronics aids, just pure man and machine 
This car is one of my most favorite ride in GT5 and GT6, and it's well known for it's inaccuracy in terms of stats and stock setup.
I made this special replica build with the main goal of correcting the mistakes and make it handle more like a Ferrari, whatever that means 
First of all, there are 2 region market for Ferrari F40, Europe and US. Both has distinctive setup from power, weight to gearing.
The EU market has much lighter dry weight and comes with lift kit/variable ride height suspension system from factory, with lower final gear and slightly different 2nd and 5th gear
This replica is a representation of EU F40 with lift kit, EIBACH ERS springs installed and further based on specification from Auto Motorsport Magazine review back in February 1989. There are some differences to the earlier version replica I have built, mainly the weight, gearing and LSD. I have used LSD profile from F355, this time I have the correct data with 60% lock LSD. For gearing, the Auto Motorsport Mag version although uses different values, also achieved the exact speed/accceleration/top speed and rpm /speed figure on each gear as the other 2 version have posted. The other 2 replica earlier gearing was based on Ferrari owner's club and manual reports, while this one is based on magazine review.
The power of EU F40 from dyno reports with cat installed of 471HP / 478PS / 478CV with curb weight as measured and reported by Auto Motorsport Magazine = 1254kg / 2763.81 lbs and 39.2/60.8 weight distribution. This is curb weight with full fluids and full tank of fuel ( 120L ) - without driver. With a driver, the weight distribution will shift closer to 38/62.
Gross Vehicle Weight ( GVW ) as reported is 1430kg ( max operating weight with driver + passenger + cargo).
Some EU F40 do not have cats installed, usually the early years model, these non Cats F40 has been reported to have in excess of 500HP, some even dynoed with close to 520PS or 513HP.
To achieve the power figure of non cats EU F40, I decided to include 2 optional upgrades path, one uses high rpm range turbo kit and exhaust manifold, the other intake tuning and exhaust manifold. The specs are listed above.
For suspension, I have used EIBACH ERS springs at 8.25kg/mm front and 12.0kg/mm rear, maintaining spring ratio for the stock F40 spring rate, as the stock value can't be achieved. Damper setup for street and track, with ARB set for balance. Toe and camber has been setup with real world alignment values, based on F355 alignment which from report share similar alignment with F40 - closest information I can get
An alternate spring rate at 12kg/mm front and rear also provided, this is more oriented for high speed cornering and sweepers.
The real Ferrari F40 has ZF Self Locking LSD, based from Auto Motorsport review specs, the rear LSD has 60% lock, I have tuned likewise, with medium preload. The previous replica LSD which uses specs from Ferrari F355 with 45% lock and high preload also listed as optional.
The corrected EU F40 ratios and final based from the Auto Motorsport mag also able to replicate top speed of real F40 at 324kmh/201mph, furthermore, the rolling acceleration time and vehicle speed at 5th gear 1000rpm has been closely replicated - similar to the tested reports from the magazine.
Various test results from Auto Motorsport mag :
60kmh-100kmh in 4th gear rolling acceleration : 6.3s
80kmh-120kmh in 5th gear rolling acceleration : 8.5s
5th Gear speed at 1000 RPM : 43.5kmh
F40 speed on each gear at about 7400-7700rpm optimal shift point :
1st 90kmh
2nd 144kmh
3rd 201kmh
4th 255kmh
5th 321+kmh
Feel free to try it at SSR7
The F40 was extensively tuned/tested at Ascari, Tsukuba, Spa, Bathurst, Nordschleife, SSR7, Apricot Hill, Brands Hatch GP and Willow Springs.
I also managed to replicate the real life lap time of F40 at Tsukuba, done on Best Motoring at 1:03.73. The car easily do 1:02s comfort soft - slightly quicker than the US F40, as it should 
Another real life at Suzuka record 2:25.27 in real life can easily be replicated. I managed 2:21.175s on 1st lap.
ENJOY 
UPDATE : Added weight figure without fuel, calculated from 120L full tank with 0.711kg = 1 litre of fuel. Weight without fuel is at 1169kg, very close to 1170kg Weight distribution at 42/58 without fuel. I have also added new suspension setup based on stock factory Ferrari F40 spring rate ratio, this is the lowest / closest to stock value possible, this setup has ride height based on Best Motoring F40 Tsukuba Battle as driven by Gan-San aka Motoharu Kurosawa, the F40 won the race . Ride height at 81mm / 81mm, visually matched The F40 with no fuel and Best Motoring ride height + stock spring rate ratio, managed flat 1:42s at Red Bull Ring on Comfort Soft in 1st lap ( cold tires ) 
UPDATE 1.09 : Added Ferrari F40 US Edition Tech Manual Alignment Range, highly recommended to be used as a base to start.
So, did you also try zero camber ? If you really want it to drive well at bumpy track like Nordschleife, I suggest to run much lower spring rate ( 10.71/10.71 ) and higher ride height ( 95/95 or 100/100 at least ). If you run higher rear spring, only increase in 0.10 increment, even 100lb/in or 1.786kg/mm increase of spring rate at the rear can cause oversteer tendency when using the camber ( 2.5/2.0 )
