Seeking advice: Please critique my drifting tune (FC)

[TakahashiRyoske]

I am trying to drift with a SAVANNA RX-7 INFINI III (FC) '90. Below is my setup, but I don't feel like I have as much control as I would like. When I compare to using a BP FALKEN RX-7, the FALKEN feels significantly easier to control. If anyone could try out these settings, and see if it is driftable as-is, or if there are major problems, I would be really grateful for advice. Or maybe some of you are so awesome at drifting that you can identify the tuning issue just by looking at the numbers. I am trying to learn to drift with a wheel (Driving Force Pro, 900 degrees). All aids off, ABS off. Tire-wise, I'm still trying to find what works best for me, whether Comfort Hards, Mediums or Softs.

I would start by either lowering your rear camber (I use between .05 and 1.0 on most RWD's) or raising your front camber (2.5 or higher should suffice in this case).

I would also lower your rear toe to o.o or even lower (if you want the rear to kick out easier, and the capacity for more angle mid drift).

For LSD, I would go for something more along the lines of:

Initial - 10
Accel - 45 to 60
Decel - 20 to 30 (or 60 if you want a true 2-way diff)

Other than that, it's looking pretty good.

Sounds a bit tight for a racing wheel user...
Maybe im talking BS, but usualy i see wheel users with loser springs and dampers than it, for a optimal weight transfering.

Weight transfering is more important while using wheels, since you will not "cheat" with instant-turning.

Loosen that up dude, dont ever lower the car that much for drift, also, if u keep rear suspension 1-2 mm higher, its a tad better for drift also.

Try putting on -21 -19, lower the spring rates alot, and keep rear one softer about .3-.5. then lower rear camber for .3-.5

But thats just my opinion, i make all my tunes myself and even succeed in them

Oh and try to raise the intial acceleration anywhere from 1-10 points, maybe that works for you too

 

[Delphic Reason]

Yes, absolutely lower the spring rates, and raise the car up a bit. Sorry, I must have missed that for some reason.

You don't want the car bottoming out on the suspension, making weight transfer difficult and all around handling, as well...

As daltonlm said, weight transfer is more important with wheel users (especially 900 degree wheels).

Try running...This is my setup with Low RPM Turbo at around 340hp

Stock Diff...

I don't use (and see the reason for) specific setups:
When i buy a car, i get comf hards and every available tuning item. (Max Power really)

Then, i take it for a spin (after standard modifications, like the LSD)
From there on, i change the car according to the feeling.

I'd suggest an LSD tune for 5 60 60, and reset the suspension to standard setups.
Lack of power imo, so I'd say a small amount of front camber, but not a lot more needed. Try it from there.

I run a rx7 like yours, lsd is set to 45, 55, 60. My suspension setup is
- Ride Height: balanced with a drop of 5 mm from both sides.
- Springs: 12.5 / 10
- Dampers (Ext): 9 / 9
- Dampers (Comp): 8 / 8
- Anti-Roll Bars: 2 / 2
- chamber 4.5 front 0.0 back
I dont know how long you have been on the wheel but my wheel snaps are fast with these settings. Throttle Control is the biggest part of this tunning to much gas will send you spinning the right away. The tunning aspect of drifting is hard to get advice on because the difference in our driving styles. I would suggest running 10-15 laps everytime you change something in settings(takes time but true tunning is done in the lab on wheels). btw I am also on a wheel.

P.S. I would leave ABS on so you do not have to mod suspension to compensate for the loss of that system.

Why are you running the car with the stock weight? You should have full weight reduction installed on the FC, that's part of your problem. It should weight 1060kg or so and as others have mentioned lower the spring and damper rates and it will feel a lot better. And CH tires all the way.

Sometimes, you can learn something with regular weight than always relying on Full Weight reduction . It could be cost effective.

No, not really I find GT5 heavy cars wear tires out, (Just like real life) But what I'm trying to say here is you should tune YOUR CARS to what feels good to you.

 

[nk4e]

True ( I will just keep it at that).

The reason for my parts selection is: I am trying to get my car as close to the White Comet's car as possible.
