So instead I will be building something that approaches an EP Ultima ST Type-R Evo, which doesn't exist as an official release (only the GP truck and EP buggy were released as Evo versions), and the leftovers of the Racing Sports will be combined with the RB body to make a long wheelbase buggy (although I might buy the correct chassis to have the correct wheelbase...). The ST will hopefully become a nice basher, I always wanted a Stadium Truck.

Bits collected so far:
Bought in lot:
- Ultima ST Racing Sports + body, broken rear arm mount & rotten tires. Missing drive shafts, mechanism deck, battery hold down bar, rear shock tower, rear shock tower mount, front body mount, gear cover, 1 front shock and servo mounts.
- Ultima RB Type-R front end, carbon reinforced rear shock tower mount, shock towers, battery hold down bar, cap screw set, CVDs, 2 front Twin Cap Pro shocks, 1 rear TC Pro shock, body, hard front plate (blue).
- Spares: RS-50 gear set x 1.5, UMW409 long rear suspension part, RS-55 diff case x3, SP-107V rear hubs, UM-401 front arm.
Previously owned:
- UM-406 Universal swing shaft x2
- UM-138 Universal swing shaft x2
Recently bought:
- UMW-105 and UMW-106 carbon reinforced shock towers
- UMW-121 Hard King Pin
- UMW-407 SP Carbon composit chassis (RB/with battery slot) + UMW-408 Special Rear chassis with battery slot (blue) - Buggy chassis, shorter wheel base will hopefully eliminate the lack of steering this chassis suffers from
- UM-105 rear suspension holders x2 (hopefully to be replaced by the hard alloy part on the truck)
- UM-112H hard 4.8 mm ball end
- UM-114 rear bumper
- UM-116 Outdrive diff half L
- UM-118 ball diff gear x2
- UM-119 diff ring
- UM-121 Diff adjusting screw
- UM-122 Torque control unit inner hub
- UM-124 Tensioner spring
- UM-125 Idler gear shaft
- UM-137 Drive pin & collar
- UM-303 Main Gear shaft
- UM-307 gear box
- UM-308 Idler gear

- UM-309 Disc stopper
- UM-313 Gear cover
- RS-12 front body mount
- W5183-01 fluorine shock case (L) + W5183-02 shock shaft (L) - to convert the short front shocks to long rear shocks
- W5182 Twin Cap Pro Shocks (M) for the front end
Ordered:
- UM-117 outdrive diff half R
- UM-126 front wheel shaft
- UMW-305 light slipper disc
- UMW-307 special motor plate (blue)
I plan to post some good comparison pictures of all the differences between Racing Sports and Type-R (Evo) parts. I also plan to measure all of the flat parts and shock towers and make CAD files for them, which I will send to Fibre-Lyte.
Some pics of the parts I've collected (not everything):
