Taubenreuther do a hidden winch kit for the Forester (behind the bumper) and also a front receiver kit onto which a winch can be fitted. Don't know if they fit the late model Foresters - their pics show the earlier model.
I agree with the front-end weight concern. I had an 1981 Toyota 4X4 truck that I added a Warn brush guard and 6000lb winch to. The extra weight ruined the front suspension over time. I suggest getting a removable mounting system then you can take the winch off when not in use to save the front end, keep the winch from long-term exposure to weather, less tempting target for theives and save a little gas pushing that extra weight down the road.
I'm looking for a Hella light mounting solution myself. I am getting a towbar mount installed on the front (for towing behind the RV) and was considering adding mounting brackets for some Hellas.
Did anyone finally put a winch on his Forrester? The total weight including mounting kit etc. seems to be drastic. 37kg of winch plus some 12kg of mounting kit for the Taubenreuther winch sounds close to 100lb or 50kg, I wonder what this is going to do to road-worthiness? I'd be slightly worried going around a corner in slippery conditions with that much extra weight up front. Should bring an uncalculable amount of oversteer. What do you think?
Warn Industries has a portable winch and a quick mount that goes into a tow bar. Doesn't seem to be too heavy, and with a little rigging it is possible to attach a receiver to the front also. This would allow you to use the winch front and rear, then pull it off and put it back into the car.
