hey guys i lowered my car at 1.7inches front and 1.3 rear and im lookin now to buy spacers but i really dont know how much size (mm) of spacer will fit my car without vibration.i have 20" rims.

 

stop starting threads. start searching.

 

there is no info in your post to give you an even remotely good answer.
What are your wheel offsets and tire sizes?

 

totally wrong section for wheel spacer topic...

But OP, I have nearly new H&R hub-centric 25mm spacer (lugs built in) - painted satin black... if that ends up being the size you need let me know if you are interested...

(for sale ***** here)

 

guys sorry for my weak language and im not a pro like u guys in mods if i didnt explain right

 

If you search things about wheel spacers and do a little reading you can probably find a lot of information that will help you. You need to find out the spec on your rims...size and offset

 

^^^ +1

and post in the wheel & tire section - not engine & drivetrain

 

Not to mention that your NOT even in the right forum.

I realize you are new, but if you want other people to take the time to answer your post, then at least do the following:

1. Do a search first for past threads
2. Post in the CORRECT forum (No, wheels do not belong in the engine forum)
3. Post as much information on the topic you are inquiring about.
