Hey man i know you posted your tune but i kind of dont wanna take it just wanted to ask you for tips for the rx7.

Sure man I dont realy know how to give tips without actualy saying what I did
I'll try be vauge but helpfull.For me some key points for when I tuned this car was figuring out where the final gear needed to be set before I fliped the transmission try and get so that the top speed will be between 155mph and 165mph in the top right of the gear graph.
With the suspension I learned that the longer the front stays lifted up from the launch the quicker the time seemed to be which I why I used the fully raised front height, but you need to get the rest of the suspension to work with this and help keep the front lifted. But in doing this it may give slighty slower 0-60 time, but the time lost in the launch is made back up from the 60mph onwards to the 1/4 line.
I rarely drag race online due to my connection, so if you're planing on using yours online it may be better to tune for faster 0-60 time so you get the best raction off the ghost tree, in which case the rasied front end may hurt the car more than it will help, but that is just my speculation I havn't had the chances to use my FD RX-7 online enough to test out which is better.
Oh and I use the stock wheels with my tune it improved my time between 0.001 and 0.005 compared to using the aftermarket GT Auto wheels.
If you're going for top leaderboard time you will need to do the launch 'trick'* thing where you wait for the countdown and press the gas just as the "1" fades out. I dont think it will do under a 9.875 on full throttle launch but I could be wrong my runs between 9.876 - 9.888 when launched full throttle
I hope this helpfull, I'm still fairly new to drag racing so im no guru at it
but I do take pride in my RX-7 being a RedSun GT5 Team member I kind of have to lol even though the RedSuns GT5 team focus's on drifting mostly and touge racing (my GT5 expertise lays in touge racing) Non Initial D fans may not understand *Notes: I dont personaly consider the "launch trick" to be a cheat, as im pretty sure in the real world of drag racing when waiting for the tree to turn green you wouldn't be sat there rev'ing it bouncing of the limiter you would have a 2 step launch control set to the ideal revs for the car, but we dont have 2 step launch control in GT5 so we have to time it when we press the throttle to get the ideal RPM at launch.*

Far out your 0-60 is like a whole 0.1 faster than me! I get 9.908

Thank you very much you pretty much answered all my qustion except one when i launch between 1rst and second i always get pulled on between those gear have any idea why.

My opinion, I keep seeing all these .001/.002/.003 differences between runs with stock vs aftermarket rims. No more of a difference than that is, it could all come down to the driver. Maybe your just not hitting that shift point as exact as the previous run...

I can confirm rims can make a difference, but it's very dependant on the car. It was Nuke that first pointed it out (to me anyway) thanks bud 👍
Not sure if it's a change in unsprung weight or just the diameter, but sometimes original rims are faster, sometimes replacements are... occasionally there is no difference at all. The biggest variance I had (think it was a Jag or Stang) was 0.030/0.040 although it's normally only thousandths. The only thing that never alters the time (for me anyway) is the type of aftermarket rims used 👍

Managed to get my FD down to a 9.866, I realy wanted to get a .865 but no matter what I tryed to do i couldn't get that last .001! 
Heres two pics using two different gear sets but they still achive the same time.
gota give props to Karo though 👍 looking at the tune he posted his gearbox setup is better than my posted tune, but I think your suspension is holding you back abit mate.
as following his recomendation for the starting final gear being between 3.550 and 3.575 is pretty much what got me down to the .866 time when I used my suspension.
But when I tryed your suspension it slowed my time to .869

Hey maccer,
I flipped your dampers, to
1 / 10
1 / 10
and it shaved off .001 for me
YMMV.

This is my whole argument for the rims. Please tell me if I did something wrong on these runs to get different numbers.

One run right after the other with out making any changes to the car, and running it in auto.

Running full throttle on Route X gives you a somewhat inconsistent turnout time, like what you showed on the video. Launching at a specific RPM will yield the lowest possible time, and consistently. Some cars can get the same time launching both ways, but full throttle tends to be more random - since you're bouncing off the rev-limiter, the RPM @ launch may be higher or lower per run.

Now I know part of what I've been doing wrong. Thank you sir 👍

Thank you my friend. Ima try your suspension when I get home and see if I get the same time as you. I was aiming for the .865 too but I couldn't nail it so I settled with my time

Good luck man, I hope you get there, I seem to hit a wall with the car, i've tred a bunch of different starting finals between 3.540 and 3.620 today and i was able to get a .866 time with any starting final bewteen 3.550 and 3.590.
All of them give different 0-60 and 0-100 times but all ended up crossing like at .866, I even managed a 0-60 in 2.339 and 0-100 in 4.853 with 3.590 starting final and that was the quickest combined 0-60 and 0-100 times i've got with my suspension which I thought would get the .865 time as my suspension gives slightly slower 0-60 times than yours but then is quicker from 100 to the finish line but that still gave me a .866 time
When I use the stiff front spring (16.0) I can get my 0-60's down to 2.338 but it makes my 0-100's raise up to around 4.857 so what ever gear sets your using must be working perfectly with your suspension to get you that low 0-100 time.
I do wonder if you will get the .865 time when you use my suspension set or if it will just work against your gear set and slow you down, will have to wait and see, the 9.865 time has to be possible in this car im sure of it.

Yeah me too bro im gona hit that time if its the last thing i do lol. When i do ill tell yoy exactly what tranny and suspension i used. Frankly its only you and me on this car and two heads are better then 1Good luck man, I hope you get there, I seem to hit a wall with the car, i've tred a bunch of different starting finals between 3.540 and 3.620 today and i was able to get a .866 time with any starting final bewteen 3.550 and 3.590.

As I have been missing Kenny's comp and tuning one car a week 
I thought I would pick something popular... big mistake
This car is a nightmare for me as it needs ultra precise shifting You guys are short shifting to 2nd right? I'm sure someone who can shift properly will do better with this tune so if nukes time isn't beaten I will send him this car 👍

Nice work Karo! I knew it would be possible 👍 and nice work fest0r good to see someone else try this car out, looks like my suspension was pretty close to perfect except the camber, but for me I personly found 5.5 front camber slowed me down =S I will have to experimet with the gears to figure out where it needs to be to get that .865 time. Either that or just do alot of runs until I hit them EXACT perfect shift points as this car needs you to shift at very precise RPM's.

Well I'm short shifting to 2nd then just before redline at the rest. I'm using this suspension:
45/45
3.0/3.0
1/1
1/1
1/1
3.5/0.0
-1.00/1.00
...but it only makes a minor difference to 0-100 when testing in auto. I think my starting final was 3.615 and a longer 2nd for the short shift. I also have an auto trans setup at 9.882 so thats what makes me think a good shifter would do much better than me.

Yeah I also short shift into 2nd aswell at either just below redline, or exactly on it, or just slightly past it. Great auto trans time too 👍 very fast! last time I tested auto with this car I was running 9.911, but that was a while ago with a starting final of around 3.7xx
I feel slightly gutted that I wasn't the first to get the .865 time but at the same time im kind of proud I helped contribute in being part of the chase to get that time and at least I can claim the fastest pre 2.04 patch time but tuning seemed easier back then
now the hunt begins for the 9.864! My setup uses them if you mean the chassis reinforcement? I havnt tested if it's faster or slower without them.
