Notes :
The replica in this build covers most of the generation models of Lamborghini Diablo with rear wheel drive version. Spanning from 1990 Diablo to Diablo GT 2000. I provided 2 weight specs for each Diablo Base Coupe - 873 built ( 1990-1998 ), Diablo SE30 and JOTA - total 150 built, with 15-28 of them in JOTA Spec ( 1994-1995 ), Diablo SV - Spinto Veloce with 120 built ( 1995-1999 ), 100 SV built for 1999-2000 and Diablo GT - 83 built ( 1999-2000 ).
Power wise, the 5.7 V12 Diablo Base Coupe 1990-1998 has 492PS/485HP, Diablo SE30 has 525PS/518HP, SE30 JOTA 590PS/587HP ( 1994-1995 ), Diablo SV (1995-1999 ) has 520PS/513HP and later years has 530PS/523HP ( 1999-2000 ). For Diablo GT, the V12 has increased displacement at 6.0L, generating 575PS/571HP.
The 6.0L V12 also used on Diablo VT and VT SE from 2000-2001 with lower power at 550PS/542HP ( 260 VT and 44 VT SE were built ). Since we don't have VT Diablo ( AWD ), I do not include it in this replica.
Each of the weight specs are based on various source ( curb weight which often do not have full tank fuel ) and some of the full tank weight are calculated based on 100L fuel tank ( 75kg ) and official test weight. The Diablo GT full tank weight and dry weight are based on Auto Motor Und Sport Super Test Data.
Suspension spring rate is based on Diablo 6.0 ( Workshop Manual ), the spring rate calculated from static load + dynamic load + flexibility spec are lower than available in GT6. So I chose to use the spring ratio instead, and aim the lowest value possible in GT6. The ride height is at 110mm and suspension as well as alignment from Lamborghini Manual are used on all specs.
For LSD, 45% lock rear differential is used just like the real life spec, set with low preload to help the car agility while staying stable at the track. Gearing for Diablo are provided in 3 version, based on the ratios offered by Lamborghini from factory. The Diablo Base Coupe 1990-1998, SE30/JOTA 1994-1995 and Diablo SV ( 1995-2000 ) uses standard version gearing from factory unless the buyer asked otherwise.
The Diablo GT often comes with EU/EEC C Version Short Ratio giving it lower top speed, but better acceleration. When custom transmission is installed in GT6, the final drive calculation is not accurate as the real car uses final drive and transfer gear ratio. There are 5 sets of gearing, the 1st one with 1.59 transfer gear ratio is standard fitment on 1990-1998 Base, 1994-1995 SE/JOTA and 1995-2000 Diablo SV ( Spinto Veloce ). The 2nd set is High Final used on Diablo SV ( '95-'00 ) which gives it much lower top speed at 186+mph ( Factory Option )
While the other 3, the 1st one with 1.619 transfer gear ratio are used as standard fitment on 6.0L engined Diablo ( GT 1999-2000 and VT/SE 2000-2001 ), while the 1.667 A and C version short ratio are optional from factory for these 6.0L V12 Diablo.
The Diablo replica was tuned and tested at Tsukuba, Autumn Ring, Suzuka, Big Willow, Bathurst, and Red Bull Ring. The Base Coupe Diablo in particular was tested at Tsukuba to replicate Best Motoring real life record at 1:07.66 set during SuperCar Battle Race in early 90's ( the Diablo didn't finish as the car spun due to brake trouble ). Motoharu Kurosawa drove the Diablo in solo time attack session, but only managed 1:08.18 lap time. The replica Diablo Base Coupe spec 485HP and full tank weight 1690kg on Comfort Hard can do 1:07.6s with ease, the replay is included for reference.
For the Diablo SE30/JOTA, SV and GT, feel free to fit Comfort Medium to enjoy higher grip.
