I would have to agree with Besercoe, Tamiya make the best shocks. Get the TRF treaded shocks.
In the latest Car Action they were doing a review on the 414 M2 and it was said that the Tamiya shocks would have to be the best on the market. Even guys using very good touring cars are now starting to put tamiya shocks on there cars as a hot up.
At the end of the day you still have to build them right but its hard to mess up a Tamiya Shock.
