you just need the multisided socket , u should get one to fit perfect on the bolts...
yep you have to torque them up properly , dont dog them or they will shear an break...
if your lookin for a perfect finish , id recommend you drop them to the wheel doctor he does a super job on wheels.. he would actually do the lot , split em spray em an stick em back together for ya...
even stick the tyres back on for ya an all...
usually around 75 per wheel he charges , but does great work...
