hello

i hava a Mille Miglia Evo5 18x8 with sumitomos tires on my gs4 and when i hit sixty and up to 70 my stearing wheel shakes and i mean shakes. Check the balance and looks fine. what else can that be. I hear that gs 400 are a very sensetive sespenction and if it dosent like something there is really nothing you can do. Please some input i don't know what to do anymore

thanks

I had the same roblem on my 17" stock rims. Went to stock 16" to get rid of that. Nothing else helped.

Usually a shake of that sort is cause by either an out of balance tire and wheel or an out of round tire.

Even a square brick can be balanced. Please take that to one of our recommended installers with a Hunter GSP 9700 that tests road force variation. I believe you probably have an out of round tire, assuming they are all balanced correctly.

Another possible explanation is that you did not install the wheels with the hub centric ring. Please private message me if you want and let me know if you got these from The Tire Rack or somewhere else. If you got them from us I can research this further for you. Even if you didn't let me know if you have any further questions.
