HPA will match or beat all competitors' prices on Haldex...IM or e-mail me for a quote.
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.
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....

FOUND IT! What I meant to say was would it be possible in future to have a mode switchable COMPETITION controller to the standard multi mode switchable unit? Or is there a mechanical issue that would prevent this?
I know at present this is not a feature, just wondering why this isnt included in the race mode of the multi-mode unit.
The switchbale race controller offers a balance for those who want "race" performance some of the time, but also the conveneince of stock or eco mode when they are commuting in rush hour traffic, or driving their monther-in-law to the airport...
Both the Gen.4 0BY Switchable "Race" Controllers (with cable or remote) and the Gen.4 0BY "Competition" Controllers for the TT-RS available.
Please specify when ordering.
Questions about the Comp version of the controller for a US spec TT-RS...
1. Does the comp version of the controller cause any binding in the driverrain during slow speed driving with sharp turns, for example when pulling into a parking space? Put another way, does the comp version allow some differentiation between the front and rear ends? I have plenty of experience with 'part time's 4wd systems (with all manner of diffs: open, detroit lockers, erc.) that don't function smoothly unless the tires can slip somewhat (snow, mud, rain, etc.) and don't need that with my TT-RS.
2.Does the comp version create any 'spooky' behavoir when driven on the street? Oversteer, snap steering, problems with wet, slippery roads?
3.Other than a bit of gas mileage loss, are there any other draw backs or compromises for street usage?
Realistically, I will drive my car 99% on the street. I am looking for mods to increase performance, but not ruin the driving experience. I am used to high powered rear wheel drive cars, so the less FWD feel the better. I have noticed that the car feels more planted accelerating out of or through a corners vs trying under braking and am looking for the comp version to help even that out and why I am looking at it over the regular, adjustable version.
