If the RS is the same sort of Haldex as the 3.2 then if you don't own one or have experienced the performance RACE mode then just stop talking and start listening. The performance Haldex is (in the end) an in expensive mod to your AWD that will transform the car into the beast that it was meant to be in the first place -- except for Audi likes to play safe out of the box. I have a remote, but really, if it were designed to be in Race mode all the time---that would be just fine with me. It's still got plenty of AWD to get through the snow and such, but does not pusee foot around like stock. Plus, the MPG is about the same. My calculations have not seen any statistical difference. People pay like $1500 but for "race" OE exhaust systems when you would be better off just turning your radio down a bit! So give it a go and get on board with a real Haldex.

Pm me for prices on a TTRS.
Keep in mind the RS already has much more aggressive tuning for the haldex than the 3.2. It already starts transmitting power based on throttle input like the blue controller does.
Would be great to here from RS owners who have made the switch and their impressions
UPS Canada is raising rates (dues to rising fuel costs) next week on Haldex Controllers (and other products shipped on "Air" service). Get your orders in before this Friday to save on shipping costs to the US and International destinations...
The Gen.4s are flying off the shelves because of all the Golf Rs being delivered...if you TT guys and gals are interested, get your orders in to secure one while they are still in stock...
I spent this past weekend driving the Motorsport Ranch Track in Cresson, Texas (3.1 mile CCW). This was my second track weekend in the TT-RS and the only two times I have driving on a track in my life.
The car is great, and I don't concieve of an improvement that this controller could make.
I did learn that: 1) disable the first tier of ESP or you may have the computer holding back on throttle input, 2) It may be nice to have the rev limiter removed or raised a few hundred RPM, 3) have enough fuel in tank before a session such that you will not drop INTO the indicated red area (~ 1/8 tank) on the fuel gauge or you will suffer from loss of prime to the fuel pump (and subsequently look like a duche bag).

On track it helps keep traction to all 4 wheels in to and out of bends...car will just not break traction.
So to recap...it is a mod that is mostly effective on track; works well with upgraded ARBs; helps carry more speed in to and out of bends as you can get on power earlier than your competition; maintains traction when the OEM version pushes the noise wide.
I have had mine for 18-mths and track the car once a month or 10 times per annum. I also have MagneRide. I would however not fit the Haldex unit again if starting over again as I can personally replicate its benefit with a suspension mod especially on MagneRide equipped car.
Can the 4Gen haldex unit iteslf be fitted on an mkiv r32?
is there any chance of the race only controller being able to be given multiple modes like the sport controller in future? I like the idea behind the race controllers more consistent torque apportionment but it sounds like it would be hard on tires and fuel on a daily commute basis....
