Reducing wire diameter to 1.5mm gives the spring a different natural frequency and internal stress, so it compresses sooner and lets the front tires stay loaded through chop and braking bumps instead of skipping.\u003c\/p\u003e\u003cp\u003eFree lengths were revised alongside the change, with fronts trimmed from 70mm to 68mm and rears from 86mm to 83mm to suit the lower RC8B4.1 shock towers. Rates run from 4.45 to 5.05 lb\/in in front, stepped by 0.25 coils so each change is a small, predictable adjustment. Both ends are marked to keep 1.5D wire separate from 1.6D in the pit box.\u003c\/p\u003e","brand":"Associated","offers":[{"title":"Default Title","offer_id":56089216418114,"sku":"ASC81660","price":13.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5063\/8402\/files\/81660_md__56074.1725448986.jpg?v=1788542780","url":"https:\/\/www.powerhobby.com\/products\/team-associated-asc81660-front-springs-4-65lb-in","provider":"PowerHobby","version":"1.0","type":"link"}
