Project FD
Target is to use 47/53 weight balance light as possible and running close to ground as possible, close to 500-546whp ~435Nm, Enkei 18" RPF1 rims, F8kg/R6kg springs, -1.2 degree camber on both ends, +0.05 (+/-0.02) front toe, 0.00 rear toe, gearbox with clutch and H-gate shifter. Preferably "premium" with interior.
Ended up first with '91 model on specs ~630bhp/~630Nm rolling on +1" sh tires around Tsukuba flat 1min without ABS and enjoying ride.. No wing yet.. Will drop setup also on newer premium FD and possibly on closer to that '99 "standard" too.
Changed to +2" for matching 18", base data was for newer version which has 17" stock wheels, '91 model stocks are 16" so had to increase size and fix ride height to adapt different rim size, it's now 2mm higher and better gripping, but unfortunately no free meal, more suspension play makes own aspect on handling, but it laps better times on all tested tracks with bigger wheels.
'02 Spirit R Type A body sits on track like clued on it with that 80/80 height.. It can handle also extra power from ECU upgrade, but not suggesting it directly, as optional extra craziness for car only, without it car beats older brother over ten seconds on Nordschleife.
All this came from video what I saw, then quick search for real setup and decided to use one multi champion setup.
Here's video of inspiration source:
Setup works directly on newer FD too, 9Kg heavier and 2mm lower
Both project cars ready using
éfini RX-7 Type R FD '91 body and on
blue RX-7 Spirit R Type A FD '02

Platinum Silver)
(+1")
Ride height for SH 82/82
(80/80)

Toe 0.03 / 0.00
Standard Brakes 4 / 4
Stock Gearbox or Quaife build 6-Speed short ratio what also works with H-gated shifting
Max speed 310 kmh
1st 2.823
2nd 1.941
3rd 1.513
4th 1.200
5th 0.958
6th 0.780
Final 4.100 (or 4.300 for more acceleration, reduces top speed marginally)
LSD 1.5-way and optional 2-way Kaaz, stock works too
5/30/19 as 1.5-way preferring this, closer street type setup.
5/30/30 as 2-way
Standard Clutch, Dual works too but standard closer to easy street setup.
Carbon Propeller Shaft
Power parts, oil change and everything EXCEPT NO SPORTS COMPUTER, gives 633BHP/633Nm
(642BHP/633Nm)
Body, NO RIGIDITY at this point. 1100Kg, painted with Sassy Grass Green (or prefer
GT6 Polarized 031 or even closer
Lime Light)

Weight Reduction Stage 3
Carbon Body Colour Bonnet
Window Weight Reduction
Ballast 70kg @+47 gives on edge of 47/53% wd
Custom rear wing at 7, painted with Asphalt (or prefer
Nero Carbonio)
A/C/C Height -8, Width +23
Wing height corrected 8.4.2016 and also adjusted wing effect on body weight balance under pressurized condition. Break even point is 7, smaller leaves front more grip and it makes steering slightly aggressive, in other words oversteering habit, values over 7 changes steering understeer. Suggest for pleasant driving to go on value 7.
Wing height corrected
last time to height -8. Well it's up to you is it closest looking to original..
Added optional 6-Speed Quaife Short Ratio gearbox, more shuffling with stick, but really suitable for this.
Minimal changes waiting (more accurate color, rims checked with minor alignments..) and other bit more powerful and never FD upcoming soon.. Peak view:
One of first tries with adjusted aero.. All possible basic mistakes included on drive, mis-shifting, late braking, excessive throttling etc.. But gives clue how it handles
