  • how tough are our front wheel bearings

    I'm experimenting with some pretty crazy wheel offsets at the moment. Just wondering what kind of reputation our front wheel bearings (and for that matter the rears too) have for tolerating that kind of thing for a few weeks.

    I've been a regular on this site since early 2009 and haven't heard of any failures. Along with all the track days I've done and the many other people (on both street and semi slick tyres), I'd have thought it would have got a mention if they were prone to failure.

    I have a vague recollection of the APR 9n3 perhaps having wrecked wheel bearings during it's development, but nothing jumps out since.

      Ok cool. I've been playing around with a variety of spacers on the front and through trial and error I think I've worked out where the KPI angle falls. I've had it running lots of positive scrub at ET23, stock OEM for early polo's at ET43 and today at ET31. At ET31 it had to have been on zero scrub because it was truly aweful with tyre squirm galore and the worst cornering I've felt on the car ever. All of this was done on the same set of rims/tyres so only offset/front track was ever changed.
      I've been very surprised at how well lots of positive scrub radius goes. Go kart like turn in but you really have to muscle it due to the kick back in the steering. more mucking around to come but I think it'll be neg scrub ET43's for the wet (just so stable) and some wide track looking positive scrub offsets for the dry. Just didn't want to kill the wheel bearings in the process. thx

        Been running ET25 front and ET20 rear for 39k+ kms, no signs of the bearings starting to wear

          That's some serious rear offset there. Well if they've handled that, then they should be fine. I might run mine spaced for a while then so that I can get used to it set up that way. Anyone know if spacers are still illegal in nsw even if they are through bolted (not PCD conversion ones)?
