Notes :
The Murcielago, successor to the cool Diablo. I made this long ago, recently drove it again and found it to be enjoyable. This replica is comprised of 2 version, 2002/2003 Car & Driver Test Base Coupe ( non LP ) and Best Motoring 2007 LP640 Motegi Lap Record.
The power and weight for the 2002/2003 Car & Driver is 572HP and 1842kg with 42.2 / 57.8 distribution, while the 2007 Best Motoring LP640 has 631HP and 1805kg with same distribution.
Suspension is custom tuned by me, as there's not solid information on the spring rate except for the front rate which is not available in GT6 ( the minimum value still too high ). I decided to use 450/750 rate, the ratio has been optimized to work with the distribution. The 2002/2003 Car & Driver has soft damper setup while the LP640 has stiffer front damper compression and rear extension to give better track handling. Ride height is set using the ground clearance data from C & D at 4.8 inch / 122mm.
The gearing has separate set as well. The 2002/2003 Base Coupe has different gear ratio fitted with the 6.2 liter V12 engine which has lower redline at 7600RPM. The Car & Driver max speed on each gear is different than most other publication articles :
........Gear Ratio Mph/1000rpm Max.speed in gears
I .............2.94...... 10.1 ......... 77 mph (7600 rpm)
II ............2.06...... 14.5 ........ 110 mph (7600 rpm)
III ..........1.52...... 19.6 ......... 149 mph (7600 rpm)
IV ..........1.18...... 25.2 ......... 192 mph (7600 rpm)
V ...........1.03...... 28.9 ......... 205 mph (7100 rpm)
VI ...........0.91...... 32.6 ......... 205 mph (6300 rpm)
The Murcielago in GT6 has 6.5L V12 with 8500RPM redline, to account for this and keep the max speed similar, a corrected final ratio is used at 2.750. An optional final 3.137 can also be used to achieve similar max speed often listed by other publication.
For the LP640, the correct final drive has been provided, taken into account the 2.530 rear axle ratio and 1.24 transfer gear ratio. The max speed and acceleration now is accurate for both version.
LSD is 1 way front and 2 way rear, employing low preload with 25% lock up front and 45% lock rear to reflect real life specification. The LSD has been tuned to provide mild understeer but still can be pushed sideways at will, similar to the real life reviews.
The rear wing is optional, while the color paint has been provided with variety of choices. The Mystic Teal Metallic is chosen to replicate the Jade Green 40th Anniversary Edition.
The replica, particularly the LP640 has been tested at Twin Ring Motegi and Tsukuba. At Tsukuba, it can lap in low 1:03s, while at Motegi Road Course, the replica is able to replicate the real life Best Motoring lap record at 2:09.955. My test lap was in 2:08s with comfort soft tires.
For the Base Coupe/40th Anniversary replica version, the real life record at Tsukuba is at 1:04.76, try to aim that time with the Base Coupe specs ( 572HP/1841kg ) and Base Transmission with 2.750 Final.
The Murcielago is heavy super sports, it has good traction and acceleration from 1st to 3rd gear, and care must be taken when braking from high speed. The brakes are okay, but might need earlier application. On medium to high speed curve, be smooth with the steering and throttle, the heavy rear end can easily cause unwanted overload on the outside tires.
This is similar to the Best Motoring lap and races, in which the pro driver Naoki Hattori has to drive rather cautiously at Motegi, slow in fast out gives good lap.
He noted that the car has understeer tendency, and the rear wanted to step out albeit subtle in process. He cited the uneasy feeling from the rear on turn in, and careful throttle was necessary on exit to avoid traction break out. He even spun at the S turn on the warm up lap ( off camera ). Brake early, smooth driving line is am must, as suggested on the Best Motoring video below. Naoki Hattori best lap during solo run 2:11.435, much slower than the race best lap set by Yuji Ide ( ex F1 Super Aguri Driver )
The replay has been provided for the Twin Ring Motegi lap, using the LP640 specs setup, enjoy 
Also the video of the Murcielago in action - the lap was achieved during the race at 2:09.955, the LP640 came in 2nd after losing power nearing the end of the race, possibly due to overheating.
UPDATE 1.16 : Updated LSD to reflect real life LSD spec front 25% and rear 45%.
Or is it just as easy to have your B-Spec driver win as it is when driving maxed PP cars in Career Mode?
Oh, and I just learned that a Murcielago R-GT was built by Reiter Engineering. I don't have specs on that car, but there is some information on lambocars.com about the race model. 👍
I'll be sure to let you know how my test drives went.
Looks like you have a great time playing with Diablos.
I will have to post my thoughts on the cars later. I'm off to lay in my recliner and listen to the televison while I keep my eyes closed. Hopefully this headache will go away quickly. 
I did an oil change on the car 
Nicely balanced, throttle steer, direct steering and good brakes. I think I like this one better than the Aventador, which I will build an SV version too ( recently announced ) 750HP, 50kg less.
