Notes :
This is one of the most challenging replica I ever made, even at the moment of posting, I'm still not satisfied with the handling 
The car is based on Paul Cain built BMW 3002 TTii, a 2002 Turbo undergoing modern transformation.
First, the engine was swapped for bigger size with more power, more efficient, lighter and more advanced in technology. A Dual VANOS 6 Cylinder M54B30 engine from BMW 330i 2001 model. To make more power, yes, Mr Paul Cain craved for more power to humiliate the poor folks who look down on the old banger at the lights. He added 2 KKK turbocharger, a TT package that runs on mild boost of 6-8 Psi, but capable of producing 335HP at the wheel - that translate to 370+HP at the crank with 10% loss on the driveline 
He reckons that with lower compression, upgraded pistons, the M54 engine will spit out close to 485HP, possibly at the crank with 12 Psi boost 
To accommodate that much power, the chassis, driveline and suspension needs some serious make over. The BMW received extensive weigh saving, chassis strengthening, custom wheel hubs, custom suspension linkages, custom sub frames, and special custom roll cage for safety and added rigidity. The real car wet weight ( no driver + full fluid ) at 2740lb / 1243kg. The BMW 3002 TTii has 8 US gallons fuel tank positioned at the rear axle ( half of original tank ), I have calculated weight at 1220kg without fuel and fluids. I also have included a variety of ballast + position. The car with driver and full fluids ( fuel and oil ) has 50.2% / 49.8% distribution, this is reflected in the ballast position of -4. Without driver, 1220kg, the distribution should shift rear ward at about 0.5%, reflected in ballast position of 2 ( 49/51 ).
The suspension is custom built by Jeff Ireland, employing Eibach Race Springs and custom valved Bilstein Damper all around. The spring rate is unknown, so I have to give my personal touch, with handling aimed at good balance, the real car is said to have almost no understeer / neutral turn in at low to medium speed. Ride height has also been visually replicated, with lower front to achieve level appearance like the real car.
I have tuned the damper and ARB to maintain balance on low speed, while medium speed needs good throttle control, while the real car has good handling even at higher speed. This is hard to achieve consistently, as the BMW 2002 Turbo in GT6 has stock skinny tires, while the real car has much wider 17" 7.5" wide front and 8.5" rear tires ( Michelin Pilot Sport ). Nevertheless, the replica should handle well on comfort soft with good throttle control 
The transmission is another part that needs serious attention, a 5 speed Getrag 265 from E30 BMW M3 is used, with final drive at 3.710 taken from E34 BMW M5. The gearing is perfectly matched to the car engine, giving good acceleration and decent top speed. I have included 2 methods to achieve the ratio, both gives the same result, feel free to try them both and pick one that you prefer.
The LSD is torque sensing Quaife 1.5 way with 25% lock on preload taken from E34 BMW M5. The LSD is tuned to give stability on low to medium speed.
I have also provided a 450PP power figure spec, simply remove the high rpm turbo kit and adjust power limiter accordingly. I also highly recommend to fit sports hard or sports medium if you have hard time with throttle control.
The BMW 3002 TTii was tuned and tested at Tsukuba, Silverstone GP, Red Bull Ring, and SSR7 At Silverstone GP, with Comfort Soft tires, stock 4 speed, 370+HP, 1220kg, -4 ballast, it managed 2:30s A good time for such an old vintage car. I have included the replay for your enjoyment and reference, witness how smooth the BMW 3002 TTii carving the track

), managed 2:04s on 1st lap on cold tires and yellow oil ( power at reduced 387HP and big fat 1500kg 
). Another Italian Supercar replica was built as companion, the Countach LP400, same recipe 
I'm also taking a break from FITT events, they don't offer much variety of feedback due to the low number of testers ( same old
