Sounds good guys. I found the problem with the binding .. There was a small piece of plastic stuff in one of the teeth. It was very small and hard to find under the grease. All seems good now. I ended up not using any shims. Thanks for all your help!
On an other note.. the kit has been going together very well....perfect fitment on everything. I like the instructions and the flow of the build. Its a little different from other cars. Other kits you start with a chassis and build off of it. Here you build everything and then bolt the sections to the chassis near the end.
BTW, has any tried the fioroni pistons in this car?
