Notes :
This is an attempt to replicate the personal car of the Drift King, Keiichi Tsuchiya.
The car was featured in Best Motoring Vtec Club Edition and raced against stock NSX-R provided by Honda ( driven by Naoki Hattori )
The car is largely stock, with only mild modification made :
Platinum White Pearl paint ( Roof and Mirror painted in same color )
Stock Engine
Fully loaded weight 1310kg ( AC/HDD SatNav/DVD )
Stock Brakes
Kei Office Coilover with Sachs Damper ( Development Model/Prototype )
Lowered from Stock : Front -30mm and Rear -25mm
Wheel/Tires : Prodrive GC06D Forged F 17x7.5J +44 / 215/45/R17, R 17x9.5J +44 / 255/40/R17
Bridgestone Potenza RE55S S tire.
The NSX-R replica has been tuned with the specs above, with weight at 1310kg, I provide 2 power specs, stock GT6 and Dyno Power. Paint can be obtained from Honda NSX Type S '01 ( Platinum White Pearl ), with the wheel uses Advan RGII in white ( the closest design available in GT6 ).
The weight distribution for base is 42/58, while I also provide 2 more, ballast position at 27 for 42.7 / 57.3 or 50 for 41/59 ( the closest it can get to 40/60 while still at 1310kg )
The Kei Office Coilover spring rate is unknown as it was custom tuned by Keiichi Tsuchiya himself, so I decided to use the closest next best thing, the DG-5 Coilover Kit specially made for the NA2 NSX. The Kei Office tuning company was sold in 2005, and Keiichi Tsuchiya formed the new company DG-5.
The DG-5 NA2 NSX Coilover Kit uses 9kg/mm front and 14kg/mm rear ( Swift Springs ), the kit was multi purpose for circuit and drift. The rate has been set, and damper/ARB has been tuned to suit the new ride height and springs. Camber has also been visually replicated with high camber, especially at the rear. The toe values uses the base from NSX-R replica.
LSD also has been set similar to stock NSX-R replica. The NSX-R when driven at the track was fitted with Bridgestone Potenza RE55S ( S tire/semi slick with soft compound ) which may be closer to sports medium.
I tested and tuned the DK NSX-R at Tsukuba and Apricot Hill. I used CS tire as baseline when tuning and it has plenty of grip. At Tsukuba on 290HP, 41/59 distribution and CS tire, it's capable of low 1:04s with ease and at Apricot Hill in 1:36s. The NSX-R should drive well on CS to SM tire.
The Tsukuba lap has been provided via replay.
The video of the race
Update : Added alternative setup with lower front extension for better balance rotation with the lower toe ( halved )
UPDATE July 2016 : Added another/second alternate damper setup for lower toe, the front and rear compression has been increased while still stable enough on the limit. Try this new damper and see which one you prefer. Tested at Suzuka East, good for 58s lap and Tsukuba 1:03s on CS tires.
