Crank Pulley Install and Info on 2005 STi
Just installed the pulley, OEM pulley weight is 5 Pounds, 10 and a half Ounces. Grimmspeed pulley is 2 Pounds, half ounce. Car revs slightly faster now, has smoother downshifts, and the engine doesn’t lurch anymore when AC clutch engages. I bought the crank pulley tool along with this, and install didn’t take too long but I had to pull the drivers side radiator fan in order to fit a deep socket into the pulley. Overall happy with the purchase
2006 LGT Install
Quick and easy install on a 2006 Legacy GT. Product is great quality and you can notice a big difference in weight between the OEM pulley and the Grimmspeed one. I was having some feedback knock on my AP before installing during on/off throttle situations, and this helped limit those and I see these numbers pop up on my AP much less in the few hundred miles I’ve drive since install. Great product for an auto as well since we cannot do a lightweight flywheel like the manuals. Would recommend to anyone, especially with the great customer service they offer!
