hey, how low can i lower my au3 on 17'' alloys??

you can go Ultra Lows but you will most probally have to get your guards rolled depending on how the tyre sits in the guard ! If thats not low enough get some Custom springs !

It all comes down to personal preference !

Get what ever the part numbers are for AU Super Low. Don't look for SL or a suffix. Have queried with K...... at Kings and confirmed the catalogue is CORRECT. The supers front or rear, may have SSL (which is normally ULTRA low) or no suffix at all (eg: KFFL-57) but they are SUPER LOW's and WILL give the car a level stance.

Now go check http://www.kingsprings.com/ for your part numbers and call around for some quotes and give them 1 shot on their opinion on shocks.. Let us kno what you find out - am researching this right now.

17"s will be fine, have to roll front guards only on E Series; AU is designed around 17's and smaller so should work in theory.
