Hello!

I need help with the sileighty. It is very understeery. I simply love this car can someone help me. These are my settings:

325 hp
Parts: everything, Turbo 2, Racing large intercooler, no aids

Suspension:
spring rate: 7 F / 6R
ride height: 95
camber: 2,2 F / 1 R
toe angle: 0 F / 1R
stabilizer: 4F / 4R
damper bound and rebound: 8 F / 8R


Tires: sports soft F / sports medium R

Brakes: 14 F / 8 R


PS: I drift with the sileighty but the understeer sometimes kills me
 
The gearing might not work properly, as this is actually a 1988 K's setup with stiffened rear springs for the 180SX/Sileighty's further rearward weight balance. Should if anything oversteer. Use S3s front and rear.

SUSPENSION:
--------------------------------------------------------------
Spring Rate:-------5.0/6.5
Ride Height:-------95/100
Shock Bound:-----3/3
Shock Rebound:---5/5
Camber:----------2.0/1.5
Toe:--------------1/-1
Stabilizers:------- 3/4
-----------------------------------------------------------------

Transmission:
-----------------------------------------------------------------
Final to 5.500, auto set to 13, then set ratios and final.
Ratios are [2.320/1.690/1.290/1.000/.800/.622]
Final of 4.660

-------------------------------------------------------------------

LSD/Downforce and others:
-------------------------------------------------------------------
LSD: 25/30/10

Downforce: 30/20

Aids: None at all

Here's some general tips i've found helpful.

Lower the front end...or raise the rear. This way, the weight of the engine is keeping traction on those front wheels more often, while the rear tires have more of a chance to break loose. I would start with the rear 10mm higher than the front and increase the rear from there.

As RJ said: make the rear springs slightly stiffer than the front.

I would also make the dampers look like this:
Bound: 3/7
Rebound: 2/8

But there is some leeway here.

Stabilizers: 3/6 Again, you have some leeway..

you basically want the front-end to react quicker (and gain traction) than the rear.

I would also experiment with more rear camber..like 2.0 degrees. Again, the rear will be more prone to "break loose" under throttle...which you apparently want since you're drifting.

LSD? I would personally try the 1-way diff before getting bogged down with a full-customized drift. But i would avoid using any differential at all if there's no wheelspin...

But if you HAVE to use FC LSD, keep in mind taht a full-limited slip device should be kept incredibly low or understeer will show up quick. Basically, even with low settings, the device will still work to keep wheelspin at a minimum. I would have it something like this: 10/15/minimum

NO tCS or ASM (but you know this already)

Mismatched tires 👍 with softer ones up front. (many players scoff at this, but i approve). It may be hard to drift iin a Sil80 with sport tires...i would try a combo of S2/S1 during races, but N2's or N3's (no combinations) if you're just going for pure drifts.

Finally, i'll tell you your settings are just a way of getting your car to do what you want it to do...ultimately you'll need to learn the best braking & turn-in points for drifts or grip-racing. How much throttle to give also helps you to break loose. All settings do is provide a platform, you'll ultimately need to figure out what works best for you.
 
I was 100% agreeing with you Parnelli till I read this:

It really depends on the car but the S14's are surprisingly hard on the fronts compared to other cars I've found. For El Capitan enduro, I used S1/S2's, but the S1's were on the front, the S2's on the back and the S1's were still wearing out at a faster rate than the S2's. This is most evident with my TCv3 entry. The extra wear from the camber and toe causes it to happen.

For one, SilEighty =/= S14. It's an RPS13 with the S/PS13 Silvia nose.

Excessive front tire wear means the car is understeery or overusing the front tires. We want to get rid of understeer, so staggering tires with less grip on the rears will help our cause. (Also, it may aid the fronts to stay alive longer)
 
I'd try increasing the strength on the rear brakes, or decreasing the front brakes a little bit.

This will lessen understeer on entry of the corner.

Interesting.

But keep in mind that xavierD1 was asking about understeer, and hinted that he was trying to drift a bit. He wasn't asking about running an endurance race. And putting harder tires up front will increase understeer...which he doesn't want.

My point to to xavierd1 (who was currently using mismatched tires) was that some players will tell you it's just 100% wrong to mismatch. But personally, i have found it works sometimes...

...however, i have not driven a Sil80 yet in GT4...i'm not totally experienced with this car except in GT2, and in GT2, i was in the habit of mismatching front & rear tires alot.

...so my basic message to xavierd1 was: if mismatching works for him and reduces understeer, go ahead and do this, even if other players tell him not to. 💡
