This is my first mod car its an 09 black sand pearl fresh from dealer. Next weekend I plan to instal nf210's Hotchkis front and rear sways and Tanabe strut tower bar. I have gotten a tremendous amount of info from you guys and appreciate it all. Thanks!!

Nice start! Your suspension will basically be done (until you wear out the stock shocks).

My advise would be to do a lot of looking around to find the wheel size & style you want. That should be your next mod, because they will make the biggest impact visually, as well as helping the handling also if you go up in wheel size.

Thanks. Alot of the spring decision was made based upon the thread you posted about the nf's. I am lookin at 18's with 225/40-18 tires but am not sure of the offset yet I think 38 to 40 should work but want to wait until the drop is made and settled. Any input on replacing the front sway with the hotchkis

Any specific wheels in mind yet?

tsw londrina black with gun metal

A new wheel from TSW. Most TSW distributors don't show them on their websites yet. I've seen them in gunmetal with a polished lip in 18x8, but I can't find any info on offset yet. Nothing shows anything black that I've seen.

Victoria Tire & Wheel lists them for only $199 each, lowest I've seen.

wheelfire says they have them but until you place the order u don't know.

correct that they are gun metal not black don't think tsw makes a black thats a great price though

But Wheelfire wants $235.75 each.

I have a friend who powder coated his infinity wheels to get them black. They look good although they are a matte finish. Any experience with that?

No personal experience with wheels, but I know others have done it. I did deal with having steel supports powder coated for a previous company I worked for, and we always had the choice of various finishes... matte, satin, medium gloss, high gloss.
