Searched all kinds of search terms, nothing found. Does anyone know what the weight distribution is for the R32 GT-R? Not V-Spec nor V-spec II. I am trying to balance out the weight because it's burning through my front tires. I want to use it in the Tsubaka 9h endurance, I tuned the suspension and all, I can get a decent time of 1'04.xxx", I can surely win by a lot if I can keep this time, but after my front tires start turning orange, it all goes to crap and I have to pit a lot more laps before my rival RX-7 FD.
 
That's likely not from your weight balance, that's because you're probably spinning your front tires, in addition to them having to handle a majority of the braking and handling duties. Buy a VCD and adjust it for a more rearward torque bias and that should solve the problem. Adding more weight won't help tire wear :)
 
going to try the VCD right now, I forgot about this thing. lol, dunno how :dunce: i went through all the tuning and stuff, but never once thought about the VCD.

so i just bias the torque towards the back? and let the front just handle the steering and braking. and allow the back for the power right?

does the heavy front of the R32 Skyline affect anything thing though?
 
i dont think the r32 has an amazingly heavy front end

you could reduce the front brake settings a bit - will further reduce front tyre wear and will assist in turn-in for better cornering
 
i tried the VCD, max setting to the back is 10/90 split. Still eats my front tires just not as fast, lol. the description for the VCD is so BS. it says max settings are 100/0, or 0/100.

Going to try this now. brake balance controller...another 10K Cr. :ouch: lol

how much front brake settings do i reduce?

*edit* edited first post to change title, since clearly it has little to do with weight distribution. thanks guys
 
just need to go for trial and error - perhaps start with 12 on the front and 16-18 on the rear
hard to say - you didnt mention what tyres are on it - but start with something, do a few laps, make a change to ONE setting and take note how it reacts

it is an endurance race, so i opted for S1's. And I gave it lots of time to try everything out, like 2hrs. tried everything, including 1/24 (lots of spins but after getting it down, still didn't help the burning of the front tires). I think Tsubaka is just too much for the R32's front two tires?
 
i find that tire wear in GT4 depends on a lot of factors. settings and drivetrain layout are important but its also very dependent on different driving styles.

i drive with more of an oversteer posture during entry into a corner while my friend is more neutral throughout his cornering. this leads to my premature wear of the rear tires compared to my front. we get similar laptimes, but i find his tire wear to be overall better than mine.

cuz of these factors, we also have numerous possible solutions.

ballast + weight distribution can even out your tirewear but wont improve your tire wear. a similar solution would be to setup biase using different compounds in the front and rear. VCD can help but thats if you are spinning your tires with lower TCS & ASM settings. this leads me to another point. if your setup has low TCS and ASM, it will add more tirewear. you can increase TCS & ASM to help you reduce some tirewear but this can make your car harder to turn in some cases.

i also have an R32 in my garage, although its a '93 N1 model. even in this car i still manage to wear down the rears faster than the fronts. so if all else fails (setting wise), you may have adapt to the car and drive with a style that conserves the front tires as much as possible. brake earlier and go easier on the gas. try not to use the heavy load in cornering to kill the small inherent understeer of the car. instead, try using the throttle to rotate the car.

hope this helps.
 
That's interesting. My Skylines always get their rear tyres destroyed before the front ones. Maybe it's my driving style - trail braking and drifting through corners. This might sound a slow way to drive but it has brought me all golds in every GT game so far.
 
If you put softer tires on the back, it won't reduce teh wear at all, but it will even it out as well as give you better performance. Maybe it would let you gain enough time to warrant that extra stop...

In terms of weight balance, you don't need to know what the stock balance is before changing it. All you need to do is change it and tweak it until it feels right to you.
 
Thank you to all of you for the replies. 👍 :)

I found that, using S1's, my front two tires last roughly around 16 minutes in the Tsubaka 9h endurance. My back tires were still good up to 30min, when I quit the race when I find myself losing by 20 secs because the front tires are just wearing like tofu on asphalt. I didn't change the back tires, just to see how long they will last. I didn't really wait until they wear out, I got a little sick of pitting every 15 mins, while my rival RX-7 hasn't pit once in 30 minutes. :nervous:

My ASM settings for understeer and oversteer are set at 0. My TCS at 3. I don't think I have my tires spinning, so I don't think TCS has any part to do with this. In the other hand, my turns are perhaps too hard on the front tires, and ASM doesn't help it (it's off). I can turn on ASM but it will lose me the race, because of the understeer compared to the RX-7. I fine-tuned my suspension for handling but it's only capable of outhandling the RX-7 with ASM switched off. It is, however, a 100+ A-spec points (don't remember exact number) race. And I am not interested in killing the opposition with a huge turbo or something, I want to have a nice, clean, fair race. :yuck: :crazy:

Hey Greycap, are those FR Skylines? Those GT-S? lol, I can get those [cars'] front tires to wear out as slow as the rear tires.

My Skyliine GT-R is a 4WD one, it's a mildly tuned GT-R (no V-spec, Nur, or anything). Original suspension (tweaked), full customizable transmission, sports exhaust, racing chip, triple clutch, racing flywheel, carbon driveshaft.

*Edit* 💡 I suddenly thought about this, would a LSD (limited-slip differential) help with this? Perhaps it will prevent slipping during my hard cornering and braking?
 
Just GT-Rs, an R32 and an R34. Try 11/10 spring rate, 5/5 inbound and 10/10 outbound and 4/7 stabilizer. I'm not sure if the LSD helps, but it makes the car faster, so buy it too.
 
try my R34 s-spec settings, they will balance that car so it tuns in very nice and tyre ware is minimal >>LINK<<
 
You said you tuned the suspension? Make sure you don't have much toe or more than about 3.0 camber in the front, as those will kill the tires quick. My guess is that maybe you turned these up to get rid of the understeer? If so, turn them down (try getting rid of the front toe completely), raise the rear spring rate and stabilizer and lower the fronts until it handles the way you want.
 
I think this thread needs to be moved to the settings forum..

AND.. your settings (including tyres) need to be posted so we can see where the problem might be
 
I don't ever use toe-in or out, and I keep camber to a max 2 degrees on either set of wheels. If you try a setting that makes the back a bit more loose (not drifting loose, but nice & loose) there'll be less stress on the front tires while cornering.
 
Here are my settings for the suspension (original) I tuned up.

Setting ------ F/R

Spring Rate (kgt/mm):
8.8/10.8
Ride Height (mm):
80/80
Shock Absorbers:
9/9
Shock (Bound):
-/-
Shock (Reound):
-/-
Camber Angle:
2/1
Toe Angle:
-2/2
Stabilizers:
5/5
 
Toe angle really ought to be zero if you want good tire life...
 
Yeah, put the front toe at 0, that's the majority of your problem. Front toe will eat tires like crazy. Also, try lowering the front shocks a little and raising the rear stabilizer a couple clicks. That should get rid of any understeer. If it still doesn't, raise the rear ride height 10-15mm.

Moved....
 
Thanks Sven and JTSnooks, I will try that right when I get home!

*Edit* I just tuned it up a bit, handles great, somehow a bit better than too. Thanks. However, it only helps minimally with the front tires. They still wear out too fast. But I found that all four soft tires can get me just enough time for the extra pit stop. Thanks everyone. If you have any more input for helping the front tires, it is VERY welcomed.
 
Yep! I concur.. The toe out at the front is killing your tires. It may help on turn in and mid-corner (if that's what your intention was) but it's doing way more harm than good, though I do like to have a little toe out at the rear (-2) to reduce some of the understeer of 4WD cars.

Your shocks seem pretty stiff too, compared to the springs. Try 6/7.. and work from there..
Camber seems fine.. reduce the rear for more mid-corner oversteer.. increase front for more mid-corner steering response.
With the stabiliser I'd try 5/3 for a few laps and then reverse it 3/5 and see which I prefer..


They're just a few things I do to 4WD's.. Hope it's of some help..

Good Luck!
 
When you have finished testing the other settings, try these too:

Setting ------ F/R

Spring Rate (kgt/mm):
11.0/10.0
Ride Height (mm):
80/90
Shock Absorbers:
6/6
Shock (Bound):
-/-
Shock (Reound):
-/-
Camber Angle:
4/2
Toe Angle:
0/0
Stabilizers:
4/7

these will get me less understeer right?

Actually they might give you more oversteer. Works fine on my driving style. If you're still having problems with the understeer, try reversing the spring rates.

I just re-read the thread and noticed that your main problem is the tyre wear issue..

Having zero front toe will fix that easily and if you're quite happy with the way your car handles you'll have to make a few tweaks to compensate for the change.

My advice is to play with the stabilisers and definately reduce the front damper to about 6
 
Thank you everyone. I am going to try to tackle this 9h Tsubaka.
