Notes :
This is a simple replica build of a stock BNR34 GTR Vspec, particularly the N1 and Nur Edition R34 with the best evolution of RB26DETT engine capable of 350+PS in stock trim. The Vspec is the top of the range R34 GTR, in real life R34 GTR Vspec N1 and Nur has been dynoed with reports of around 345HP to 350HP ( 355 PS ) at the engine. I have included 3 spec, 350HP Nur, 345HP N1 ( Gr N ) and 336HP stock GT6.
The Vspec suspension spring rates of the real car 4.00 kg/mm front and 5.00 kg/mm rear. The spring rate can't be set in GT6, but can be very close, and I used the ratio as well, with damper and ARB tuned for neutral balance. The stock factory alignment has been used for the base suspension.
The car weight is 1560kg, with weight distribution using real life spec at 57/43, and both has been replicated. This should give the close to neutral balance of the real car and oversteer when pushed hard.
LSD is set in 2 way this time, with setup giving good amount of lock and low preload. An alternate LSD with 1.5 way arrangement also provided, the 1.5 way will give much more freedom in turn in under braking.
Tire base set is comfort soft with aim to set performance against real life Tsukuba lap record which is 1:04.57 driven by Keiichi Tsuchiya on a R34 GTR Vspec Nissan test car with LM mag wheel, race brake pad, some track tweaks and N1 spec engine which very likely have 350+PS.
In GT6, the time can achieved with comfort soft tire with near perfect lap just like the real life 1:04.57 lap did, perfection at the limit. While the factory stock R34 GTR Vpsec lap record is 1:05.32 driven The Professor Nakaya Akihiko, this can be achieved in GT6 with 336HP stock power.
The R34 was mainly tested and tuned at Tsukuba and Bathurst. The replay of the lap at 1:04s has been included, the lap was done with 350HP spec to match the real lap acceleration/speed/RPM at braking entry and exit. Suspension uses base set and 2 way LSD.
UPDATE : Added Nissan R34 GTR '99 Bay Side Blue paint chip for accurate/correct shade.
Added alternative damper setup for more neutral handling on entry and exit, compare with old base setup if curious.
Tested at Deep Forest, managed 1:30s lap easily and 1:37s at Apricot Hill Reverse with alternative damper, base 2 way LSD and max rear aero at 80. ENJOY the more fun R34 GTR Vspec replica 
With CS, the tires should last better on rainy track. I have tested the Sti R205 with 335HP, very quick around the corner but slower top speed, while the R32 and R33 has 365HP should be on par with R34, Evo X and Sti, 2:31s on CS. Target is 1:56s on last sector ( conrod ), around 155mph top speed.
we would be skating and slide into the wall 
?
Too busy and I barely have time post my own work.
I think our good friend 
.
I've just built the R32, R33 and Impreza and was just about to set up a room to test them. Why did I have to check in here first!?
