howdy there folks!

awhile ago i was curious to see if there was a difference between the stag rs4S rear swaybar and the R33 GTR rear swaybar. so i bought a stock R33 GTR swaybar for $50 just to compare.

as u can see their profile is indentical, but the GTR one is 2mm thicker (however they are both hollow).

now i was scepticle that a stock GTR bar would be any better, but i installed it anyway just to try it and it definately feels tighter. Although the increase in bar size is only small the whole car feels more stable in corners. i was quite surprised by the results. i thought id take some pics along the way to help out anyone who is thinking of trying it for them selves.

Now this is only for those of us with RS4S stageas. there is no guarantee the gtr bar will fit an auto stagea as the rear subframes are different. i will look at it later in the yr when i try it on my mates auto stag.

before we start the disclaimer: this is a guide only and i accept no responsibilty for any damage or injury sustained by you or your property by attempting this. your on your own out there kids!

1st the only tools u need is: 1 can of wd40 or equivilent (not essential but it helps), 10mm open ended spanner, 12mm socket or ring spanner and a 14mm socket or ring spanner.

2nd jack up the rear of ur car and support it on chassis stands.

3rd undo the end links by holding the rod with the 10mm spanner and undo the nut on the bottom with the 12mm

4th now undo the swaybar mount bolts. you must remove the front bolt completely, but the rear bolt only needs to be loosened.

5th remove the swaybar. it may take a little manuvering to get it over your exhaust but i should come out easily. notice the rear mount bolt remains as the bracket is slotted.

6th give the bolts and links a bit of a clean off with WD40 or wire brush or even just a rag. the dirt on the threads makes them hard to do up.

7th take the mounts and rubbers off your swaybar and put them on the gtr one.

8th now just put it all back together in reverse order. but pay attetion to the following points:

if your having trouble with the swaybar fouling on the exhaust while trying to do up the mount bolts u may need to lower it out of the way. just remove the rubber hangers at the rear.

ensure all the bolts are done up nice and tight.

if you let your exhaust down dont forget to hang it back up.

well there you go. for $50 and an hour or two, you too can tighten up your rear.

thanks for reading. i apologise if i wasted your time, i tend too ramble on a bit.

Heavier rear swaybar is the single best thing you can do to stop your Stagea floating around corners.

For the RS4T (awd auto) you need a BNR11XX24mm (add a Z for adjustable). This is a solid steel 24mm bar and a huge upgrade. The label might be different but if you quote those references they should be able to find the equivalent.

Installation as above (or check SKs supension thread). Don't forget to use the supplied lubricant on all the bushes.

ive played this game before

this isnt an easy upgrade for an auto RS4

i learnt the hard way

Just confirming for everyone that the RS4S rear bar won't fit a series 2 auto stagea due to the difference in rear sub-frames.

just lucky i got a manual :P

Good write up this! Cheers :P

thanks, i thought i should give a little something back to the forum that has helped me

Ive got a whiteline rear swaybar from the sydneykid group buy ages ago for sale, its to suit an auto rs4 (wont fit rs4 s manual models). I swapped a 260rs cradle into mine so its no longer suitable.

anyone keen im chasing $100 + delivery for it as im in Perth. Should be around $20ish depending on where u live.

PM if your keen

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
