pulling after installing 20's and a wierd vibration
 

I just had my 20's installed after the tanabe nf's were installed.
It seams to have a slight pull to the right after the install, what could cause that?

Also while I was driving on the stock wheels I had a slight vibration when I would give a little steering input to the right. I thought it was due to the factory tires. Now that I put the 20's back on with Continental DWS tires it still does it only with slight steering input to the right and not to the left.

Any ideas?

for the pull, did you do alignment? could alignment be off? if not, did you try to swap the left and right wheel? see if the pull go to the left? if so, seems like a tire might be defective

can't say for sure on the vibration though

^ yup what he said. let us know if you have any vibrations after the spring install, are u RWD or AWD?

springs
 

I didnt notice any vibrations with spring install, rwd

I have a pull to the right and vibration. Turns out my tires were defective. I also need to get an alignment done as well since my springs were replaced too.

Your pulling could also be due to tires. I had low pressure on one tire once.

FWIW, when I had my DWS's installed, my car also drifted to the right. A simple swap from left to right cured my problematic radial pull.

are the tires/wheels balanced? might get them to re-do that.

you might want to have them road-force it. hope this helps.

Yes, I would also do a road force balancing on all 4 rim/tires in the 20 inch group. Since you mentioned having vibration with the new springs and the stock wheels, get the alignment done with the new 20 inch wheels too. Be sure that your tires are of good brand since i have experience bad tires with vibration that were found to have high road force numbers. Also check to see if your 20 inch rims are not bent or out of round (road force machine can check this).
