GFB pulley kits are designed to improve acceleration by reducing the rotational mass (inertia) on the crankshaft as well as parasitic loads from the driven accessories. The effect is similar to a lighter flywheel, and the engine feels more lively and willing to rev.We know that people are sometimes concerned about possible adverse effects of lightweight pulleys and underdriving, but rest assured we have done our homework! The underdrive ratios have been optimised to ensure there are NO adverse effects on the performance of the accessories, and whilst it is true that some engine types do suffer harmonic issues from lightweight pulleys, we steer clear of those. The kits we release are thoroughly application tested and do NOT cause engine damage in the short or long term.Fitment:SUBARU B4 (BE, BH, BT) EJ20TT MY98-03SUBARU STi MY02 (Aka \"Bugeye\") Use 2001 Pulley Kit For MY02 STi Models, And Pulley Kit 2010 For MY03-05 STi Models.SUBARU WRX MY01-02 (Aka \"Bugeye\")","brand":"GFB Go Fast Bits","offers":[{"title":"Default Title","offer_id":48736196559166,"sku":"GFVM_2001","price":229.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0051\/2249\/0456\/products\/K3cAh47RK3.jpg?v=1707509025"},{"product_id":"go-fast-bits-subaru-wrx-sti-99-00-forester-gt-01-02-lightweightengine-pulley","title":"Go Fast Bits Subaru WRX\/STi 99-00, Forester GT 01-02 LightweightEngine Pulley","description":"GFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft.Most of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses.
