Notes :
The Nissan GTR is one of the car that I have so many in the garage
Ever since GT5, I had about 20 of these at all times and in GT6, I have about 10 or so now, all are replicas.
This one is the most basic replica, with stock tune and some corrections on power, suspension and weight distribution.
Power has been reduced to 473HP / 480PS to reflect official power as tested on Best Motoring, weight at 1740kg ( official curb weight value ) and weight distribution at 55/45 - as measured from corner weight.
I researched quite a lot to find the CBA-R35 GTR 1st gen spring rate, then I stumbled a GTR owner who had a chance to speak with one of the Nissan GTR key engineer during a special GTR promo event. He posted the spring rate, many doubted him, but after doing more research on later model year spring rate increase and the NISMO package, I decided to believe and used it for this replica build.
Stock spring rate : F 550lb/in and R 300lb/in, this translate to F 9.82kg/mm and R 5.36kg/mm ( rounded for GT6 ) Stock ride height is retained, with damper has been tweaked for optimum handling balance and ARB to reduce push on entry, soft but not harsh. The Nissan GTR spring rate gets higher/changed every model year from 2008 onwards.
Camber and toe uses early GTR factory manual alignment presets, later models have 3 preset, daily city driving, sports and track. The changes are very minor, slightly higher camber and similar toe range. For this replica, I provided 2 preset, daily/city/street and sports/track. I obtained these from GTR forum, taken from early gen GTR manual. Another 2 are my own personal setup based on the factory alignment. Try all of them and notice the difference, pick one that suits you best, or simply play around with the value range.
I mainly tested the car at Tsukuba and Motegi Road Course. These 2 tracks have been the proving grounds for the GTR on Best Motoring show.
Keiichi Tsuchiya posted 1:02.125 lap time at Tsukuba on stock GTR with Dunlop OEM tires. Aim for this time or better.
In 2009, MCR owned Nissan GTR '09 model, in stock form, driven by Keiichi Tsuchiya posted a best lap of 1:01.931 at Tsukuba
My test lap was 1:01.4xxx on 2nd lap run using my personal setup sports/track alignment preset.
Naoki Hattori posted 2:07.600 lap time at Motegi Road Course on stock GTR with Dunlop OEM - SP Sport 600 DSST tires. My test lap was 2:07.4xxx on 1st lap run using my personal setup street/daily driving alignment preset.
If you want added challenge, run the car at Nordschleife and aim to beat 7:26.700, driven by the legend Toshio Suzuki ( 480PS/1740kg ) back in 2008.
