Best Audi A4 B5 Installing A Front End Strut Tower Bar
Standard on B5 S4s together with 2001.5 A4s is a front end strut tower bar. Older model A4s are lacking this chassis upgrade. Simply bolting the S4 bar is impossibly because the S4 chassis genuinely has the mounting blocks for the bar welded in.
Our brethren inwards FRG noticed that the A6 also has a strut tower bar standard. Even better, A6s from '98 to '00 had bolt-in brackets. The Germans receive got been adding the S4/A6 "domstrebe" inwards around form to the early on B5 chassis for awhile now.
Ok let's larn started....

Modifying the S4 bar
In social club to piece of job the S4 bar amongst the A6 brackets novel holes together with a chamfers must hold upwards added.

Two holes volition hold upwards drilled on the passenger's side together with ii holes on the driver's side. Use the tab hanging off the bar every bit reference.
Use a boom or a punch to hammer a pocket-size indentation at the pump of each hole. This gives the drill something to bite. While drilling the hole, add together around spare stone oil to the hole to aid inwards drilling through the steel bar.
Now examination gibe the brackets to the bar. You volition uncovering the corner of the bar binds on the within curvature of each bracket. Using the Dremel take away plenty stuff from each halt of the bar to allow the bracket to sit down even against the bar. Make certain the holes notwithstanding line of piece of job upwards together with the top of each bracket is parallel to the bar. Use to Dremel to slot holes every bit needed.
Modify the passenger's side bracket (RIGHT)
On the passenger's side the bracket volition press against the A/C hardlines (see below). There is a sudden border on this bracket which should hold upwards broken amongst the Dremel tool.
Painting
The exposed metallic on the S4 bar together with the right A6 bracket should hold upwards painted for corrosion resistance. I used around dark hi-temp pigment I had lying around.
Fabricate the A/C line of piece of job jacket
To preclude the A/C difficult line of piece of job from touching the A6 bracket border fabricate a prophylactic "jacket" yesteryear cutting a 2" department of automotive hose lengthwise.
Installation
Ok...pop the hood together with take away secondary firewall encompass similar y'all would if removing the ECU. Running off the positive terminal of the battery along the firewall on the driver's side is a thick wire secured inwards ii places to the firewall.

Loosen the battery clamp together with slide it dorsum to the rider compartment every bit far every bit it volition go.

Driver's side strut bracket bolts heavy washers together with A/C lines
Passenger's side strut bracket bolts together with heavy washers
Strut bracket bolt together with heavy washer removed
Remove the bolts together with the heavy washers. Since the A6 brackets are just every bit thick every bit the washers, the washers volition non hold upwards re-used.
Install the S4 bar. Make certain y'all receive got it oriented correctly. The tab hanging off should hold upwards pointing downwards together with the "nut side" of the tab should hold upwards facing the rider compartment.
Slide the bar inwards betwixt the battery together with the firewall from the passengers side. It should larn nether the brake reservoir.
Loosely install the driver's side A6 (LEFT) bracket over its mounting holes.
Install the A/C jacket every bit shown below over the closest A/C line of piece of job to the battery.

Notes: this was installed together with tested on a 2000 1.8t amongst an OEM battery. If your A/C lines create non await similar the ones pictures or if y'all receive got an aftermarket battery, y'all may receive got fitment issues.
Cost for parts was nearly $100.
*Update* H5N1 amend screw (slightly shorter) could hold upwards P/N: northward 090 378 2 (m8x25).
Also, RKA has clarified why the S4 bar has a threaded tab inwards the pump of the bar--it seems the firewall is bolted to the bar at that point. I know the A4 firewall doesn't receive got a hole there, then it would accept around drilling to add together this feature**
