sutol 0 Posted January 16, 2008 Going to drill my own discs How many holes you think or should I dimple or both ? Share this post Link to post Share on other sites
swordfish210 20 Posted January 16, 2008 I'v never thought that drilling discs was entirely nessacary, it's just weakaning the disc and adding lots of places where cracks could form. You'd be better off getting some ATE powerdiscs Share this post Link to post Share on other sites

You'd be better off getting some ATE powerdiscs ATE powerdiscs are expensive and grooved, which is worse grooves ,dimples, or holes ? Share this post Link to post Share on other sites
swordfish210 20 Posted January 16, 2008 well you can get a bit of pedal vibration with groved discs, but it's better than a drilled disc that is more likely to crack in my oppinion Share this post Link to post Share on other sites
Batfink 201 Posted January 16, 2008 drilled disks really are not needed anymore as pads dont produce gases like they used to 20 years ago. All you will do is weaken the disk Share this post Link to post Share on other sites
GLPoomobile 958 Posted January 16, 2008 Didn't you say your disks were 50 quid? I'm pretty sure ATE powerdisks are cheaper than that. Share this post Link to post Share on other sites
sutol 0 Posted January 16, 2008 Didn't you say your disks were 50 quid? I'm pretty sure ATE powerdisks are cheaper than that. 38 quid including vat, ,, I'm undecided about me dimples now Share this post Link to post Share on other sites

sutol 0 Posted January 16, 2008 I would NOT get drilled disks as a mate of mine hade them and within a month he had cracks coming frim the holes. Right, sound advice all of it. Seeing as I have made up a template for drilling 15 holes in the disc (and very accurate it is too) I,m going to drill dimples in them because they look racey and I wont have been wasting my time with the calipers and protractor and jig saw etc..
