I have a stock 02 SX Viper that I'm looking to do some light clutch modding on. I've found the 4.5G Yamaha rivets for the primary, and I think I have a line on a 53/43 Helix. I think I'm just going to replace the primary spring with the stock one just to freshen it up. But I'm struggling to find the green secondary spring that is mentioned on this forum, at least one that lists compatibility with this sled. Does anyone have the part number for this?
Also, I've read on here that the rollers(?) should be replaced with slightly wider ones on some clutch mods. I'm not using heel clickers or anything so is there actually a performance benefit involved with this? Should I look into that as well even though I'm running a mostly stock primary?
BTW, I'm new here and the information on this forum is EXCELLENT! Cudos to you all. Thank you in advance!
