will i have any problems with fitting 18's, or will i have to do some fender rolling? BTW, it currently sits right at 25" in the front.

But it will depend on the wheels you select, and their widths and offset.
And of course which tires you choose.

I read your other post...2 hours for a spring/shock replacement on a B6 A4? Wow...you got game. You torquing down the bolts with a torque wrench? I have done a lot of installs of coilovers (H&R/Stasis/intrax/KW on B5 A4/S4, and StaSIS tracksports/streetsports on B6 A4), but I could never do that job in 2 hours.

We remove the rear springs without touching the subframe, spring comes out in under 5 mins. I usually work with a second person for this car, thought it'll be a lot nicer when I get my lift next month!


That's where we save a ton of time.
Fronts of course are straightfoward, since the aluminum uprights don't have the corrosion problems on the pinch bolt. Plus the fronts have 2 fewer nuts to remove since the top bushing and upper control arm plates are integral.

This of course would be for a simple shock/spring setup. Coilovers obviously would take longer, depending on the height adjustments.
