Has anyone used the BSP Trick Springs from NR-Racing ? The site says they are 10.8 lbs at .850" lift & they last longer than the OEM springs. I have a Predator 212 with a Jet & Header. are they cool to throw in my engine ?
I would stick with stock springs if you are not upgrading flywheel and rod. You may get a few extra rpm, but you are putting more strain on the flywheel and rod, not worth it unless you are racing IMO.
