yea I did some practical research on why they break, and i came up with is .. the holes that are drill in each shoes intersects with the outside groove they put in it, so when you put the spring on the 2 shoes first, before it lines up with flywheel posts, you can see the spring comming down a bit in each of those whole, so when you have it installed, they lay right on the post whenever idle, correct? So all I have been doing is trying to learn and teach myself how to tune the car just so it will run. I know I need to watch my high temps, but whenever I have got it to 220-230, take it for a drive, car comes back with spring broken. those post the springs are sitting on are just about as hot if not the hottest part of the engine. ive went thru 3 springs in 2 days and havnt even got to drive it more then 2 minutes at a time..now thats crazy! and needs to be fixed , looked at whatever!
