Honestly...
Bearings are a MUST!... Best £10 you'll spend on the car...
Decent shocks are advised, something like B4, XXXCR or even the ansmann Xpro shocks are all good, there are others out there its all down to your budget....
One last thing on a personal note, ceramic diff balls, about £10-£12 are a nice addition...
Any more questions feel free to PM and ill do my best to help you out...
