To be most safe..install the latest version of the Neuspeed subframe brackets...use the CPP uplinks...with the spacer on the back most mounting location (with longer bolts) and set the 19mm bar on full stiff. This will keep the axle half shafts farthest away from the CPP uplinks.

YMMV, but I have a lot of experience first hand with the Neuspeed rear sway bars, 11mm, 16mm, 19mm, 22mm, and with no subframe brace, version #1 brace, and now the version #2 brace.

where would you want the spacers, and why? i'm trying to visualize it, but i don't get it.

right now, i don't think my sway bar or uplinks are anywhere near hitting the axle half shafts.

I've got the stock plastic uplinks, and the rear sway on the stiffest setting.

To be honest..everyone that mounts the sway bar from the start thinks...no way that uplink and axle half shaft can rub..no way. Yes way. The subframe flexes with the additional rigidity of the bigger sway bar. Something has to give...and what usually does is the subframe. It moves a little bit here..a little bit there..and before you know it ...it allows the axle half shafts and uplink arms to meet. I am not saying that it happens on all cars...but I have seen it enough to know that it is something to watch out for. Ask Warren **** on the Motorsport forum about it...his uplink arm broke...as did Bryce..both on their B5 S4s.

As for the spacer...the sway bar has four mounting locations...one attachment at each sway bar end..and two additional mounting locations underneath the gas tank. On these two last mounting points I have seen a CPP set up where a spacer is located on one side of each of these two mounting points. The spacer, in effect, moves the CPP aluminum uplink farther away from the axle half shaft. Without being under the car..and pointing to the location..it is kinda hard to explain. Jack up your car tonight, if it isn't too frickin cold where you live, and look at the mounting points of the rear sway...you may be able to see where you could add a 1/4" spacer.

Hope this helps.

if you simply add a spacer in between the bushing mount, and the subframe, then there won't be as much pressure on the bushing to keep the sway bar in place. in addition, you'd need longer bolts for the bushing mount to the subframe.

Yep...a flat, rectangular shape, 1/4" thick spacer

They're not too expensive, pennies on the dollar more than the stock ones.
