    Interesting! I might have seen a bit of this when not used HARD for a while but Iv never run my finger over it to feel, I assumed this was down to be running a pretty aggressive pad. Ill keep and eye out, I have only put a small grove in my discs when running my pads to low and the hangers were contacting the disc.

    Do we know what pad he was using, and if he tried changing the pad to resolve this, as isnt pad deposits usual due to compound and what kind of temperature window you use them in?

    I was running Ferodo DS2500 at the time (the standard pads that come with the kit - hated them with a passion), the discs had seen approx. 8 track days at that point IIRC. I wouldn’t say that the DS2500 is a particularly aggressive pad, in fact I would say they were far too mild for my liking.

    Now switched to PMu HC+ but haven’t tracked the car enough (due to lockdown) to tell if the compound has made a difference. That said, they are excellent pads for pure road use but not aggressive enough on track - I have ordered a set of Endless ME20 which will be going on as soon as the PMus wear down.

    Yes my experience with FedEx (and most couriers) has been the same, I normally just got with JapanPost for that reason in which case RM or Parcelforce handle the charges and they tend to be pretty accurate with the calculations.

    I’m keen to try the Pirelli P Zero (PZ4) myself - they’re often compared to the PS4 on Porsche forums but come off unfavourably in that Pirellis take longer to get up temperature on the road. However that’s a good thing to me as it suggests the P Zeros will have more resistant to heat fade than the PS4, and the general consensus (based in what I’ve read) is that the Pirellis have the edge on the Michelins in both grip and feel when properly up to temp - which is not generally an issue in a track environment.

    Yep the widetrack LCAs definitely add camber, as mentioned in my other post I was able to get -1.3 using those alone and no camber bolts / top mounts 🙂

    Actually that’s given me an idea to check the adjustment screw on the arms, which could be the source of the noise if loose... and thank you for mentioning wheel bearings, which I suppose could also be the culprit as my car is relatively high mileage 100k miles / 160,000 km, has been running spacers (only 10mm though) and is tracked regularly so that could be it as well.

    I don’t think it’s endlinks rubbing since I’m running stock type struts (TRD rally suspension) and stock ride height, the endlinks are the solid Perrin urethane ones (i.e. there are no ball joints) which I fitted 2 weeks ago as my old links were worn anyway. The noise was there before and hasn’t changed since I changed the endlinks so I don’t think it’s related. I guess it’s one for my specialist to look at, hoping it’s not the LCA bushes as I’m not sure how easily one can get replacements from Cusco, and they probably won’t be cheap either 😕

    Here is a link for the widetrack LCAs (might need Google Translate though!): https://www.cusco.co.jp/products/i/etc-parts/86brz_23.html. They’re not cheap but as I’m running skinny wheels (17x7.0J ET48) it helps to push the wheels out a little without using spacers which I like.

    Good idea about painting the bolt heads - I had also thought of that but only after they had been removed from the car 🤦‍♂️ will definitely try that though if I go back to using camber bolts 👍

    Not sure why my bolts were slipping, or perhaps that wasn’t actually the case - I just know that my camber can change as much as 0.6 between each alignment (which at one point was between each track day and I was going once a month) and the explanation from the shop - a reputable GT86 specialist - is that this was something that just happens but perhaps (i) this is actually the effect of other suspension components moving, and (ii) loctite / paint etc. on the camber bolts might help reduce this “slippage”.

    Thanks for the video - I can’t remember if I’d already watched this one but will check it out - I’m genuinely stumped as to what the noise will be, it’s definitely metallic sounding but I checked for rubbing and there was none... as you say, a bad mount would not just make noises when going over bumps which is definitely the case here (it’s dead silent when steering), will capture a video when I next go for a drive and also check the spring perches in case one of the coils isn’t seated properly.

    Failing that I’ll have to take this to my local specialist to diagnose the problem, I need to pay them a visit anyway to install my O2W oil cooler and updated radiator for when track days start again (after the lockdown) 🙂

    Thanks Church. I’m actually running -2.2 camber in total camber at the front, -0.9 from the Pedders and -1.3 from my widetrack front LCAs. I was using camber bolts to get to -2.0 before the Pedders, but found that they would slip quite often (after every track day) hence the reason for changing to angled mounts... the clunking is now making me wonder if this was a mistake, but I probably just have a bad mount which should be covered by the Pedders warranty 👍

    Pedder topmounts for our cars are not that long in market though to tell much about them in long term use, to tell how well they last with big enough assuredness, but i hope they will do the job of more camber but w/o issues of WL's. Whiteline ones were plagued with binding of their bearings imho due multiple reasons, not all related to eccentricity itself. For example stock top spring perch of twins conical center was a bit wider then that of impreza-s, so tended not just rest on inside of bearing bet also on mid & outer ring of bearing IIRC, WL com-c-s also supposedly don't have bearing in rubber at angle, so at higher strut camber angles instead of being perpendicular, they may seen extra side loads, further increasing chance of binding. Most people going for extra camber do so for more optimal alignment for track use, so more load on them. Also imprezas/wrx/sti are heavier cars then twins, so more mass/load may also reduce chance of WL Com-Cs bearing to bind.

    Hey Church, can I ask how you’re getting on with your Pedders top mounts?

    I had mine installed in January this year and have been very happy with them, however one of them is now starting to clunk over bumps after only 800 miles and 2 track days - might have just been unlucky though, and got a bad one.

    Cheers

    I’m still amused that you were somehow charged £1 less in import duties, despite the fact that we placed our orders at pretty much the same time 😂

    No tyres I take it? How does the car drive on these compared to standard?

    I actually have a set of AD08R (205/55/16) for these as well - they still have between 5-6mm of thread so a decent amount.

    I had these on my car for around a year and tracked a couple of times on these, the fact that they are 7.0J wide (vs 6.5J for the OEM 16”s) gives a more square setup and they are not wallowy at all on tyres with stiffer sidewalls like the Yokos.

    Anyway, feel free to PM me for more details if you’re genuinely interested.
