    Stoke Audi on the forums quoted me about £65 I think a few months ago, £10 or so cheaper than my local Audi dealer. But either way, it's not an expensive mod.

    Made a big difference to the handling IMO, helped the understeer a lot. Here are the part numbers i asked for.

    RS4 Rear ARB Kit including:
    1 x RS4 Rear Sway Bar (Part #8E0511409AL)
    2 x RS4 Rear Sway Bar Bushings (Part #8E0511327D)
    2 x Bushing Brackets (Part #8E0511439)
    4 x Bolts for Brackets (Part #N10127707)
    2 x Bolts for ARB links (Part #N10528103)
    2 x Bushing Brackets (Part #8E0511439)

    Did mine on Saturday.

    [​IMG]

    I bought the ARB, bushing, bushing bracket and bracet bolts. Used the original drop link bolt.

    Tricky part was getting the ARB out from behind the twin exhuasts (170TDI) I undid the two brackets holding the exhaust at the back and dropped it onto an axle stand - I reversed the car onto some ramps.

    Only took about an hour including a cuppa.

    There is only mm in it but then when you uprate an ARB for any vehicle the difference is only a few mm.

    It certainly feels flatter in corners and doesn't roll quite as much.

    That's a front ARB for a B5 A4?
    The Front ARB on the B7 A4 and B7 RS4 are the same width if I remember correctly, so no need to change the front

    Had mine done at AMD Essex last week on my tfsi quattro. Parts cost £75 i think plus labour to fit. Didn't believe the hype that it would 'tranform' the car, but i was actually quite shocked at how much flatter it makes the car when cornering. Highly recommended!

    Get it done. Pound for pound, the best mod you do on a B6/B7.

    Does the 2005.5 S4 have the same diameter as the RS4? I believe the later models are, but not sure about the early B7's.

    They're the same bars.

    I did this a couple of weeks ago and the prices have gone up since some of the posts on here, in total it's about £170 now with all the bolts, brackets, bushes etc.. although I did replace the drop links too, that was from TPS with trade discount too!

    If anyone reading this thread is still unsure about this mod, having bought and fitted one myself I can say it's most definately the best mod and first mod you should do on your car after fault repairs and general servicing (including PCV & turbo bypass valve replacements).

    The A4 handles poorly with the smaller standard rear ARBs fitted. The front ARB on all models is the same beefy item. Audi really should have put the RS4 rear 24mm ARB on all models as it stops the lean and lurching between corners and literally transforms the handling. I was pleasantly amazed at the difference. My built thread (link in signature) has part details, prices and photos of the ARB being fitted.

    As been said before, DO IT!! :racer:

    Even at that price, and with an hour and half's labour to get fitted, it's still the best pound for pound mod that can be done to any B6 or B7.
