After racing with the 4.10's I broke last fall I had decided to use the 4.88's and my mini spool to finish the season last year (1 race) So yesterday I go out for a race to test my 358 with some changes but when I jumped on the car a little with part throttle the car felt a little weird on the rear like it was walking to one side. I only got 2 passes on it and went home. Tonight I pulled the cover as I am going to put my Auburn posi and 4.10 Richmond gears in it now. I pulled the cover, drained the gear lube and to my surprise my mini spool has the two parts that go through the pin are cracked through in half, not good. This was a Richmond Mini spool so if you are going to run one of these get a different one as I think the material is over hardened. My old min spool that was 20 years old had some cracks on the main parts that hold the axles in but I decided on a new one, what a waste of money. If I do this again I will get a Strange full spool.
