Hi thefan,
Thanks for your kind advice.
Prior to reading your post, I ordered (as well as misc tool/oils)
1 x 3Racing (#3RAC-WX124/PK) Wheel Adaptor (4mm) for Sakura Zero - Thick
1 x MUCH MORE (#RS-PMA36X) Rush 36X 1:10 Touring wheel Pre-Mount Tire 36deg (4 Tires w/Wheel & Inserts)
1 x MUCH MORE (#MMS-30) 100% Silicone Shock Oil #300
3 x *Yeah Racing (#MG-48023) Aluminum 7075 Hard Coated Motor Gear/Pinions 48 Pitch 23 Teeth
1 x MUCH MORE (#MMS-35) 100% Silicone Shock Oil #350
2 x Kawada (#S48-74T) Super Tough Spur Gear 48P - 74T
1 x 3Racing (#SAK-47) Rear Stabilizer Set For 3racing Sakura Zero
1 x 3Racing (#SAK-46) Front Stabilizer Set For 3racing Sakura Zero

So the the turnbuckles, transmission pulleys and springs would be the next thing I try but I really need to get the car built and get laps in before I drop more dough.
