Hi

im wondering if anyone has any idea what the problem may be when my steering wheel shakes badly when i drive over 90kmh. This only happens when i have my aftermarket wheels on the car which are 18/235/40s.... when i got my stockies on i have no issues at all... ive had it balanced and aligned, and this didnt help. Im thinking it has iether to do with the tyres( which in IMO are terrible) or 1 or more wheels are slightly buckled

anyone got any ideas?

cheers

Are you running spacers?

If so chuck them in the bin.

If not its prob tyres or a rim, more then likely a tyre especially if you say there not great tyres.

Do the wheels fit the hubs correctly? You will need hub spacers if they dont, otherwise your wheel studs are taking all the load instead of the hub. The alluminium ones are like $30 of ebay.

Theres so many things that can cause a vibration, flat spots, inproperly balanced wheels, no hub rings, buckled wheel etc.

Could be a number of things. Do you have hub-centric locators? If not, make sure that when the wheel nuts are done up, you do them up diagonally. So do one up, then do the one opposite, and so on.

Or if the tyres are quite old or poor, then another possibility is tyre location. Take it to a wheel or suspension workshop that knows how to do a thorough wheel balance. They will have a machine that can tell them whether the tyre is in it's most suitable location on the rim. If it's not then they can rotate the tyre to it's best location.

thanks for all the input.. i did take to to a mechanic, he said there are a few reasons, wheel or wheels most likely buckled and also damaged cv joint boots... i dont have spacers on there or anything like that... but i think that may be the real issue at hand...

      Thanks for your insight, it being basically useless will impact my decision for sure. I thought it may help the engine breath better I guess. But then again, I have also been told that tuning an RB20DE is also not worth it. Exactly, we follow EU Regulations. There is a bit more leeway on older vehicles. My Porsche 924 came without a cat from factory and managed to pass, they still mentioned that I have quite high emissions on it though.

      My apologies, I stand corrected. Thanks for registering to mention this! And thank you for actually reaching out to the council to clarify. This is the sensible thing to do and the opposite of what I was alluding you were doing. I may have seen too much outrage and hate being fueled on the internet and it has made me a somewhat cynical old man. Sometimes it is easy to forget that there are real people behind websites and accounts. In my defence, CarExpert and CarExplore do read quite similarly at a glance. I shall try and do better in the future. (Please stick around to get the latest scoops on dealing with old Nissan shitboxes )

      Don't bother. The poor little RB20 doesn't make enough gas flow to challenge the flow capabilities of even the littlest cat, and you won't make any extra power, and all you'll do it soot up your rear bumper. Plus....is Malta not runing under Euro regs?

      Hey Daniel, sorry to hear that and thanks for posting up for us at a really hard time I only knew SmoothLine through the forums, we never met as we are based in different states, but when he was most active on here he was quite a while back so not many of the current crowd might remember him. I am pretty sure he was active in the Queensland SQU club but that is defunct now too (times are changing and we are all getting older). Farewell SmoothLine!

      Turns out depending on whether the car was equipped with TCS or not there are different signals coming to the dash, meaning there are different speedo clusters.  Wired in a speedo calibrator box from aliexpress and now works fine.
