I also have my spare chassis modified to use the Pro 4 /cyclone front arms After I broke a front arm yesterday i needed a solution didnt get to finish it at the track but i will this week. I ended up using CA and pieces of papertowel's and it held up for 2 qualifiers and a hefty battle in the A-main





Im going to test this out but its mainly for a back up plan if i get in the same trouble again Im still using the E4 arms

Shock and sway bar mounts are 99.9% in the same spots.
