P3, the bolt to hub type spacers are technically more secure and are easier to mount your wheel onto, but are heavier (unsprung weight) and you need to make sure both sets of bolts are done up 100% evenly to eliminate any chances of wheel wobble caused by the slightest amount of flex.
The differences in price you'll see with bolt through spacers between H&R retailers like DPM and Amazon sellers are that DPM sell with bolts and some other online retailers will sell minus bolts. Make 100% sure of what's included before paying and make sure you order radius bolts if using OEM wheels.
Don't go wider than 20mm on the back or 15 on the front.
I'd say 10 front and 15 back will sit pretty perfectly.
