Have to agree on this.
I've decided to purchase the Tamiya 54752 TT-02 Steering Upgrade Parts Set and 2x Tamiya 54947 TT-02 Carbon Damper Stay II.
I couldn't get my hands on a reasonably priced set of TRF dampers so decided to make an order for the Yeah Racing Shock-Gear 55mm Damper Set as I've seen quite a few positive comments on this set.
UPDATE
Following on from a previous posting above. I've now ordered Tamiya 53585 3mm Shim Sets, Tamiya 53587 5mm Shim Sets, Tamiya 9805922/19805922 Urethane Bushings, Yeah Racing Alloy Wheel Hex Washer Set (Thick 6mm) and finally Yeah Racing Alloy Wheel Spacer 0.5mm/1.0mm Set.
These new additions should remove any slop, help tightening tolerances and minimise wear on certain parts like the drive, shafts and other areas of the chassis.
