Kyosho Ultima ST GP/EP rear suspension holder RS-5/UM105

thingiverse

Kyosho Ultima ST Racing Sports/Type-R/EVO GP/EP rear suspension holder. This part is also discontinued and these wear easily, at least in the Racing Sports version of the car. I hate to see cars getting trashed because parts are not available anymore. This is a hybrid version of the rear suspension holder. It has the same suspension geometry than the original part, but it offers you a flexibility to choose the style of hinge pin. This part can be fitted to Racing Sports version, that has screw style hinge pin, but this part also has set screw holes for the Type-R/EVO style hinge pin (i added two of these set screw holes). It also has small pin holes underneath, where you can fit the 2mm pins if you have Type-R/EVO chassis plate. This is reinforced as much as possible, there is not a lot of space between the rear suspension arm and these suspension holders. Depending on the print setting, it might just slightly contact with the rear suspension arm slot. But its nothing serious, you can just sand it slightly with sandpaper. I didnt have any problems, the fitment is spot on. The winglet style i added to this part is mostly cosmetic. I hated how the original part didnt sit flush with the chassis plate. Enjoy and drop a comment how did it work for you, or if you want any changes to be made! Also check my other parts that i have made to Ultima ST Racing Sports/Type-R/Evolution chassis.

The first version named "FINAL_Rear_suspension_holder_RS-5_UM-105_hybrid_v2.stl" are the Zero Deg Anti Squat parts. I uploaded also the 1DEG anti squat parts for those who like to tune up the suspension. I will do a 2DEG parts also, when i have time. The "beaty flap" that sits flush with the chassis might need to be shaved down a little with the hobby knife, because i didnt do anything to it when i modifyid the original design. Both designs have 3,8 degrees of TOE IN per side, if i measured it properly.
