sorry if this is in the wrong section or if this seems like a pointless topic but its not...........

i have an r32 gtr with i think r33 brembo disks and calipers, my current wheels are work cr emotions 17x9's front and back with an off set of +17, i find that i get vibration through the steering wheel or steering wheel shakes.........could the off set be a possible cause??

i was looking at just getting some cheaper 17 or 18 by 9's are there any new rims around that look decent and wont cost a fortune?

my only concern with my rims is the off set...........can any one give me some insight into if they are worth keeping on or not???

thanks

Offsets in themselves cause shudder. It might cause tramlining and change the steering response because you're changing the track and the net suspension geometry, but if the wheels are in good condition to my knowledge it shouldn't shudder.

And the rim widths offsets you've given aren't completely different to other GT-R owners, or otherwise we'd all know about it.

In what conditions are you getting the shudder?

If its only under brakes, it could be warped discs and a light machining should fix it.

If its all the time, then have the wheel condition, balance and alignment checked.

But don't buy cheap wheels. They're heavy, which ruins the performance, and they're generally softer so they're more likely to buckle on you...which means you'll get the shudder again.

Thanks guys I have had the wheels balanced and aligned 2 times, the wheels are not bent or warped at all and are all true

The suspension im running is new koni adjustable shocks, and shorter springs, all bushes and suspension components are newish

It only happens when I hit around 100km other wise its not there………..pretty much as soon as I hit 100kmh it start to shake

What other things can cause this??? unbalanced Drive shaft?? 4ws?

its starting to get annoying cause as you konw these things start to become alive at around 100clicks

thanks again

My experience has been that 100+ kph vibration is ALWAYS balance. The first thing I do is swap the front and rear wheels. If the vibration moves from front to rear or changes in frequency then its wheel balance. A lot of tyre shops just balance the wheels on the inside. Skylines (4wd's in particular) need the wheels balanced both inside and out because of the wheel width. Check and make sure yours has weights on both the inside and the outside of the rim. If it doesn't then I would suggest going back to the tyre shop and asking them to check the inner and outer balance.

:P cheers :)

also check if the wheels need those little metal seat thingys that centre the wheel on the hub.......mine didnt have these and they were fine with the old tyres but as soon as i got new ones they were vibrating like hell at about 80kms p/hr.

i dont know exactly what the name of them is but they basically centre the wheel nice and solid to the hub ......

good way to check take all the bolts off and if u can jiggle the wheel on the hub then u probably need the seat things.

"HUB RINGS"

When you remove the rim, in the middle of the disks/studs there is a circular lip. If the diameter of this lip is smaller than the diameter in the rims, then the wheel can move off centre, causing it to vibrate.

If you need a good wheel place, i highly recommend Bob Jane T-mart, at Watergardens S/C. Speak to Mark and ask him to check if you need a set of hub rings on your rims. I just got a set for my rims (my rings are plastic). They also ballance the inner and outer of the rims :)

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
