I'm running the stock shocks on my '91 RC10 team car. They also leak. I'm running the longer arm RPM world's suspension on this car but using all stock shocks so the fronts are a tad short for my liking. The world's front end originally went to the longer RC10T front shocks which work out close to the medium Schumacher length although are still tad longer. If I'm going to buy new shocks anyways, may as well go big bore. I'd love to find a way to retrofit the new Losi big bores on my JRX-2 as well but at least the shocks on that car work just fine right now.
