RX-7 Type R (FD) '91 Drift Tune, Needs Review/Refinement

[mtec]

So I’ve been trying to get the ’91 model to drift better. But seem to be struggling with taking it to the next level of sweetness. I started off using Dylans1o drift tune but didn’t quite suit me, so i start tweaking. So wondering if anybody’s interested, could they give it a whirl and let me know what could be changed. Thanks

Being that I drive with a wheel, and don't know what you use. One thing off hand I know I'd change is the Toe and Camber. For me personally I'd only have a max of about 1.5 Front Camber and a Max of about 2.5 Rear camber. As for toe I don't usually touch it often, but I'd say a lower front and rear toe as well. Then personally I use a Low # in all of the front susp. (ex. around 6 Spring rate, 2-3 front dampers) then a higher # on rear. (ex 13.5 - 15 Spring rate and about 5-7 dampers on rear). Save your settings though if you're willing to try mine that way my settings don't worsen your current tune

Comfort Hards on front and rear
Negative front toe and lessen the rear
Lose the downforce
Rear camber shouldnt be more that 2 same goes for the front
Lower the front roll bar
Add weight

I'm using a DS3, I did start off with lower number but ended up here. I was wondering if I started to chase me tail and start over compensating in other areas because I had problems,
I'll give it! Thanks

I'm not sure I agree with this, but I don't agree with any of the tune either. But, as I told him when he asked for help with it prior to posting a work-in-progress tune, everyone drives differently and their tunes reflect that. I do, however, agree with your suggestion to add weight.

 

[mtec]

Starting to get somewhere, should the weight be centered? Just messing with the wheel alignment now camber angle 1.2/1.8 & toe of -.3 / .05 I think -.3 is bit start OS a bit again

 

[BenBurroughs]

I think it needs more weight than it needs the weight to be evenly balanced, but a good tune takes into consideration the weight balance of the car and for drift tunes I rarely bother with toe increments less than .05 (such as the .48 previously used), but that's me. You're starting to get somewhere with the camber, in my opinion anyway. I'd put a little more on the rear because the car's still rather light and a little more camber will keep the tail from flying out beyond the point of no return.

 

[mtec]

Well just pulled 7491pts around the mini ring not great, not bad though. Better then were it was.
CA 1.6/2.2 & TA -.25/.05, probably should of added the weight before continuing.

 

[Warren4649]

Points have nothing to do with how good a setting is. I can make points with a stock car, does it mean stock cars drift better than tuned ones?

I find your spring rates a bit hard for the weight of the car but apparently you play with a controller so it might be wiser to have stiff suspension as weight transfer can get tricky on the DS3.

With that being said and besides suspensions adjustment I know I would set everything differently than what you did. Brake bias is weird and top speed of 180kpm (I think you mean kph?) makes me wonder how you drift on fast tracks.

 

[mtec]

Well it's not a bad starting point, just pulled a bronze on the Madrid City Course Drift Trial! So from nothing to something in a weekend. A little more refinement and she will be a sic little drift box. Thanks for your help dudes, and ben for helpful quick replies.

180kpm (I think you mean kph?)

Yer, Banana fingers make something something. Not much of a mystery that I was talking metric.
Also, the Correct symbol the compound unit is km/h or km·h-1 (for kilometers per hour) if ya want to get all tech.

I know points probably aren't much of a measuring stick, but compared to what I was getting before the changes, it was a good way for me to set a bench mark and try and better it.
If you have any advice on how to improve my setup, I’m more than willing to try it out.

 

[Warren4649]

I'd say put more brakes up front than rear. And if you use the stick to brake set the brake at stronger values.

Also try to invert your front and rear spring rates so that the front will have a higher value than the rear and do the opposite for ARB's.

LSD to 10/60/60 or 5/60/60 would be better. I used to set my LSD like yours (more or less) and the car was less predictable.

CH tires all round.

 

[mtec]

Thanks Mate, I'll give it a go. Thanks heaps for the info much appreciated.

 

[eddyac]

When you got more front brake power and are past certain angle you can gain more angle while you braking.

 

[fastfox400]

Here is my setup that i use on the same car
Ill start with suspension then diff

-12/-17
10.7/6.1
5/4
4/6
3/5

3.4/0.2
-.15/0.2

60/45/5

Also try running comfort hards front and rear. You get better with practice. When running 2 different tire compounds you will end chasing the setup because the car will never be stable..

 

[mtec]

I'll change the brake setup, and try the alternate Suspension/LSD settings.
Think i'll have to wait for the weekend the way things are looking.
Some really good info and great feedback. Thanks

 

[mtec]

So.. Had my set working well for me went online and it's a bucket of ****. What's the go? Try tuning it out with no luck

Physics online are different from offline. It is exceptionally easier to drift offline. Personally I think your current tuning is still off, but I don't care for sharing my own.

 

[mtec]

That's nice you don't care to share, wasn't asking you too. Other than some info on how to change the setup I have to suit online.

 

[BenBurroughs]

Just a tip mtec, and not really about the thread topic either, but your experience on GTPlanet may be improved by getting more use out of the "Edit" button at the bottom of your posts instead of multiple posting. I'm not saying to edit your original post or anything like that, but if you see something in an entry you want to change before any replies on it have been made, please edit, it makes for better reading for others.

 

[D-Max]

Try this. This is personally what I use and my cars never fail to point where I wish. Also, use CH on both front and back or CS. Whichever you prefer. Don't mix tyres!

People might say my setup makes no sense, but it works perfectly well.

Suspension
Ride Height -20 / -18
Spring Rate 8.2 / 10.7
Damper Extension 7 / 3
Damper Compression 3 / 8
Anti-Roll Bars 2 / 6

Wheel Alignment
Camber Angle 3.8 / 1.0
Toe Angle -0.32 / -0.20

 

[mtec]

Yer I'm seem better control with hard rear springs also, thanks for the info D-max. I seem to be getting there with my setup, spose thats the fun of it.
