I know powerslide's out according to his site, you could try sending kris at daniels pitstop an email, I can't find them on his site - thats probably good tho, as he has heaps thats not on his site yet which means you have a good chance. Or try giving Hstore down south a call, I'm not sure if they have any or not but they will be at the kurnell event so you could get them to order it and bring it down if you haven't got one by then. If you wanna pay thru the nose rchobbies usually has them.That's what I was planning to do....just change the spring to the high rpm and leave the shoes as is.....Can't find a HPI 8K spring anywhere though!
Mike what engine do you have? Most of the clutches are all 54mm from what I understand. As far as the engagement goes, it'll rev HARD before it moves and when it moves it will surge forward, not like a stock spring with a nice and progressive take off - these springs launch. You can get it to ease on a bit with some throttle control. I didn't like it in my MCD with stock 26cc zen and jetpro, the engine was a dog for the car and it was too jerky to drive around slowly but I'm about to throw it in my baja with same engine but reed ported and overhauled with zero drag seals and a dominator :2guns: .I put in my 8k spring and shoes in yesterday but Im having an engagement problem. I might have to use my old shoes and 8k spring?
