well not to sure whats not to trust but im not sure if i need tapered bolts for standard wheels sure some one said you need different for standard and after market
 
Well it say: IF YOU ARE USING STANDARD MANUFACTURE / OEM RIMS THEN PLEASE SEND US AN EMAIL IMMEDIATELY AFTER PURCHASE AS WE WILL NEED TO SWAP TO RADIUS BOLTS TO ENSURE A SAFE FIT.

But I don't know myself if it correct
