I just ordered my set of 18x8 Axis Decades With 4 225/40/18 Nankang NS-2 Tires. Can't WAIT to get those things on. I got them from Wheelmax.com Their website was the easiest to understand( I'm still learning big time!) The only question i have now I'm hoping someone on here can answer. The Wheels are 35mm offsets, which im starting to understand what that means lol....But I want to drop the car now...But How Low Can I go? lol Thanks for the help...I'll take as much as I can get!( Hey at least I'm not pretending to know what I'm talking about) Thanks!

 

TRD is the modest drop (1.25" front & rear) and probably will give you the least problems. (If any.) You may not think that will be low enough but take a gander at the pics...
TRD Springs with 18" Flik Artics and +35 Offset...

Almost flush with the fenders...

I have the same rim (18x8.5) and tire size as you. I love my set-up because the ride feels like stock. I would say TRD or Tein H.Techs would be your best bet. (If you don't want it 'slammed'.)

 

Hey thanks SOOOO much, I'm not looking for like crazy low, just...clean. I want the car to look clean sitting still and driving, so 1.25 sounds pretty good, and damn it looks nice...Thanks!

 

youll be pretty close to flush with a 8" wide wheel and +35 offset. Mines is flush with a 7.5" wide wheel and +35 offset. I am on tein stechs which is pretty low i guess, but its cutting it close.

 

I hope you got your 10% off for being a SL member.
