Is redrilling a disc/rotor hat from 4 x 100 to 5 x 114.3 a bad idea? I thought this was common practice for people doing the cheap ITR brake upgrade with Prelude discs. I took my 4 lug StopTech hats to a machine shop and they weren't too interested in re-drilling the bolt pattern.

Thanks

well ive known a few people who have done this with no problems to this day...
me personally.. i wouldnt do it, maybe let a profesiional do it and measure it up perfect.

actually, the people i know who have done re-drilling went from 5 lug to 4 lug,
both were putting mugen active gate brake sys. on there 4 lug civics.......

let me know how it turns out.. and good luck

 

Thanks. I definitely wouldn't do it by myself. The hat on the StopTech setup is a bit thinner than the stock one piece hat/rotor. Does anyone have any pics of what the re-drilled setup looks like?

Thanks
Ben

its possible...

The only real downside you should keep in mind, is that cracking may occur over time, mainly at the lug hole(s) area since you'll be slightly swiss-cheesing the rotor. Depending on how far apart the new holes will be drilled, making more holes (in the lug area of the rotor) will make it less rigid since you're taking away from the spacing between the factory holes. So cracking may occur between the factory holes & the newly drilled holes...

Hope that all makes sense. lol..
