How goes your car handle?

I am running a staggered set up with the 9s on the rear, my wheels are balanced and straight, but i am still getting a lot of vibration at the steering wheel

Time for the Hartges i think :cool:

Then something else is wrong. Get the wheels balanced someoen different just to be sure. But look at suspension bushes, balljoints etc. Before condeming the wheels.

I found that with the borbets the ride was quite unnerving at high speeds. They are BIG heavy wheels and due to the stretched tyres there isn't that much rubber to soften the ride. I seemed to have worse traction with them even with 225 tyres! This was on my black car where evry suspension component was replaced so it was all good there apart from the neg camber on the rear.

Thats a good enough reason for me to put the Hartges back on,

the borbets are ok for cruising :cool:

You are running a slightly large tyre profile, mine is 40 and have no problems with high speeds :)

Im running borbet b's 9j all round 205/40/16 3mm spacers up front car handles no problem even upto 100mph not that I do that often...I think alignment and balancing will sort your issues

if the wheels are bent then you've no hope. wide wheels will buckle easier than skinnier ones.

Saying that, you have a shake through the steering wheel, which means it's actually your front wheels that are the problem.

it's possible it might be loose, some bolts may be loose, buckled wheel, heavily warped discs, poor tyres.. If you've not had your fronts balenced try that first and check the spigot rings havn't collapsed as a lot are plastic and suffer fatigue
