Steering Is Shaking At 120km/h

and the tyres he's named are both shithouse and mis-matched, so I'd be inclined to believe it was a hardware issue), but if the mechanical components are capable of doing something with the right setup and the workshop didn't then its a fault with their workmanship or attitude.

are the tyres mis-matched? i have to agree with the being shitty though... but as they came as a deal with the Volks, i thought it would be ok to drive them around for awhile before changing them. And yes, the rims are second hand but has been professionally polished and checked. the tyres shop checked the rims again when i did balancing for the 2nd time and all seems to be good. I do agree that simply brushing the problem away by saying balancing was done till 110km/h and its all good is not really helpful. Its not as if im expecting my car to be balanced and aligned to 250km/h but just 130-140km/h. Now i do believe that many of you out there have traveled at that speed, i have also seen 4wds going at the speed on the freeway.

I meant mismatched front to rear.

While generally not the cause of a vibration problem, putting two different kinds of shitty tyres on the car just points to cutting costs. If the wheels were similarly cheap, it may be because they were damaged and repaired previously...which may make them unbalanceable.

Try another shop out, and tell them of the issue you're currently having. If the other shop fixes it then at least you know to never visit the original tyre shop first, and you can be assured that your problems are not with your rims but the workmanship of that place.

If two independent professionals are unable to fix it, then it's looking more and more likely that it's not fixable. If you still have your old wheels, you might want to pop them on both now and after that alignment from another shop to see if the issue is replicated.

I think if you have had them balanced and it improved stop there. Id be starting to look at things like control arm bush's swaybar D bush's and linkpins.

no spaces dude.. and had those hub rings as well...

hey mate, make sure you have the four hub ring in and they are the correct ones for the aftermarkt rims. Even little play in the hub rings mainly at the front will cause vibration problems for you.

If that don't fix it, then make sure they don't have flat spots in them or uneven tread wear. Or flip the tyres on the rims.

I reckon it has to do with the different tyres and there speed ratings..... may front one differs from the rear ones of the speed ratings ? make it vibrate....i've some 3rd brand 18" wheels in my car with falken tyres never been vibrated even at high speeds.....thats just my 2 cents....

Anyway, in my quest to find out the issue, I have now gotten myself re001 all round. 235/45 on the front and 255/40 on the rears... vast improvement i must say. but when im driving at 130, the slip light keeps flashing. Might be the tyres being brand new? But got advised that it could be the tie rods being loose as my mate had the same issue before so I am going to pedders for another checkup!!

this sounds similar to the problem i was having with my r33, replaced all tyres, just stopped it from happenin at 80km/h an did it at 100km/h,

problem ended up being the front suspension had gone, i replaced the stock suspension with coilovers an havent had a problem since, even at 180km/h+which was done on track, not on the road

[uncouth32]

was there any indications of your front sussy on its way out like weird noises etc?? although the vibrations are reduced significantly, my steering wheel is not straight when im travelling on a straight line. coilovers will be coming up next after my defis are done today. either that or turbo upgrade.
