The T3 gear levers are not known for their precision, precisely… that is why, as part of the upgrade, we propose these two acetal guides. This material is guaranteed for life. In the photos you can see some that are about 20 years old and next to them the acetal ones. The originals, apart from being deformed, have a lot of play. The references that they replace are 251711207E and 251711207D. Depending on the year, it has one or the other. Choose yours below. If you have any doubts, look at the front brakes, if they have a floating caliper it is Post, if they have a double piston fixed caliper it is Pre.
