    Day 2 managed 8x 1:07s, 4x 1:08s. Pretty happy with that.

    It sprinkled during lunch which presented an opportunity to learn in the changing/greasy conditions. I knew the kerbs, and paint would offer less grip. Because, that's what Martin Brundle and Cromp say. Ho-lee-shit, I never realised by how much. Track fell away so I got a little inner-bratwurst going before I packed up and headed home. Can't recommend these open pit days enough.

    There is a bit of a knock forming on the front end. Possibly shock lock nut coming loose again or something else. All will come apart again to check how it held up over last 1000km~


      So I didn't do shit, except quickly hose literal shit off after a spin at SMSP.
      LHS oil cooler is the wrong part according to the manufacturer, since they're in Netherlands they want to see the "wrong" bracket they sent is in good condition for reuse. Don't see a reason it wouldn't be.. Screw it, not worth sending back.

      Foggy SMSP North. This was fun - no italics:

      Fog didn't lift until just before lunch. Achievement unlocked, 1st after all had done 1 session - lol. It's interesting, you'd think a softer factory suspension would suit the damp track but the rear diff really tightens up and punishes you harder.

      PB for me @ 1:13.6. Didn't improve as much as I thought when it got drier but at least home in one piece. And extra shit from spinning earlier on wet grass:

      1:13.9 on drying track:

      Gearing is much much better with 18s and a 295/30 rear.

      Last vital bit before all the solid/spherical/monoball stuff goes in, is finally en-route. Decided to go with Bilstein 2ways. Much back and forth with Tractive/MCA Golds - easier to go KW/Bilstein/Ohlins etc. All the cunts that MCA made Golds for on E82s/1Ms were all spec'd differently inc measurements. It'd be a massive a fuck-around going down that road - Yeah nah.
      Ohlins is probably the best kit for the road and along with KW is common tried and tested. Bilsteins... well, apparently they just work. 570/800 rates to start. Puts the frequency around 2.5hz/1.8hz. Springs are cheap and maybe actual testing > mathematics.

      pitch under brakes.


        Car seems to want to rotate easily and quickly mid corner. Will you soften up the rear?

          I took way too long to settle on something, I'm just going to slap it in then overthink it after. Preferably get it on scales first and see how much RHD, engine tilt+turbos, fuel etc affect it.

          The front spring can easily be swapped out. The rear is a hybrid helper/main progressive but not really progressive. Was actually the tipping factor in the decision, the rest articulate improperly and bind on the crappy 0.56 motion ratio. Custom rear camber arm is too much messing around. Other option is rear C/O conversion, which was pushed by Tractive but not going full send retard on this car.


            Forgot what I said before the forum db reverted.

            Fixed this the "What's a torque wrench way?" FR top strut nut loosened up. Got away this far reusing locknuts, not bad.

            Last Sunday did a clubsprint at SMSP South. Conditions were mixed and actually awesome when it rained. At the top of the esses it was sprinkling pretty good, barely a drop on the S/F side.
            Dry conditions provided a little opportunity for a back to back comparison with last time I was here:
            • PSC2 245/265 19s staggered fitment and OEM midrange boost curve. 1.04.7.
              Felt smoother with less movement especially under hard braking. Could take the kink flat. While it was under-tyred esp on the front, it felt nice, ample control, rear grip. Braking was good, traction was ok, rear lateral grip it shone. Get a bit sideways and it bites a little but that is ok/expected.
            • AD08R 265/295 18" Rays ZE40, 3-4psi more in the midrange. 1.04.4
              Did lots of 1.04s this time. It didn't feel faster, if anything it had a little more front end but it was basically oppo or holding the wheel straight to get out of corners.
              Moved around a lot esp under braking. Was very easy to light up the rear but these tyres are quite forgiving allowing you to pull some hectic ulleh powerslides. Was really fun esp coming up the hill after the hairpin. A few tank slappers were had trying to take the kink flat. I'm sure the marshal at the flag post winced at least once. I'd say I had more fun and that's what it's all about.

            The last 2 outings in comparison to Wakefield, this set don't feel as good. Definitely not seeing the "they're good down to the cords" behavior in them.

            Getting somewhere with Demon-Tweeks and coilovers. ETA is 30/09 as per their automated system :huh: If moons align such as used A050s from WTAC competitors - maybe I can try them out in Nov at SMSP GP.

            There's an intermittent hum/vibration forming when I come to a stop from the front. Weirdly, it's not transmitted into the steering wheel. Discs are worn very unevenly with a blue tinge in them likely overheated when thinner. Visible/feelable runout. Probably down to minimum at a guess and need replacement, will know once I have them off. Meanwhile, looked around for aftermarket OEM fitment discs:
            -Brypar: 2.1k for Prime-S two piece LOL,
            -PFCv3: 10400USD, 630 for replacement rings,
            -Girodisc: 1100USD, 700 for replacement rings,
            -OEM: 475AUD. Lol. M tax? Nah, just aftermarket tax.

            The offset of the hat is the same for the F8x cars (m2/3/4 etc). Why there are two part numbers for the same 380x30mm disc/hat Anyway, if they don't make a 360mm, that's a nope.

            Got some more spherical bearings for the RTABs. Everything will be solid/rose-jointed except the rear top strut mount and the inboard camber arm. Haven't found an OEM that makes that size bushing yet.


              Since August it's been parked for various little things to knock off. Started with a different custom-made to spec (height/throw/offset) shifter and stiffer front/rear bushings for the carrier. Did it all up, before I realised the metal flex disc has a TSB out. Apparently they epic fail and completely shatter launching itself into the tunnel etc. More common fault on diesel models. Oh well, I'll be in there again to do the clutch anyway later on.

              Cleaned more mud while I was under there.

              Coilovers got sorted out. It took a phone call but an apologetic chap; Sean @Demon-Tweeks sorted it out. Ordered a bunch of fasteners that need to be replaced to tackle it. Went with a Monroe rear upper shook mount with stiffer durometer.
              Camber/top plate design is pretty good. It looks like a 2-piece design with the monoball bearing housing attached with a pair of hex screws. Sits deep enough that if you want to go full-retard, you don't need to notch the towers to move the damper further inboard. The limiting factor are the sliding slots itself. Anyone that wants over -3.5~ can just make a new offset plate further inboard from the damper position. Or this plate can probably be drilled out to move the bearing housing and hence damper inboard without fouling the strut tower at all. Something to consider down the line, although I will probably not.

              Removed the rear upper camber and guide arms, front castor / tension arms to replace rubber bushes.

              Put in the front struts while I was there. Little comparison:

              Stacked OEM reinforcements on top. No one really uses these on E8x/E9x cars. Thought behind it being due to the triangular shape of the Bilstein top mount, this would spread the forces the tower is subject to a bit better. I figure these are factory fitted on specific markets or "rough terrain" trim / region models:

              There's no preload on the spring stack, so it was easier with this particular Bilstein camber plate to insert it into the strut tower, then insert the damper in the top mount's bearing afterwards. Had a brainfade moment, threaded up the top nut on the damper then unloaded the suspension. Idiot me, didn't snug up the hub pinch bolt enough and the entire hub collapsed and put a lot of stress/force on the brake line. The absence of a front caster/tension arms didn't help. Can't see any cracks on the exterior or obvious damage along the crimps, but will have to test it and ideally just replace it.

              These came back in time for the weekend home stretch. Hook the two upper arms up before I can drop the lower camber arm for the rear dampers/springs otherwise. Then get someone else to do the subframe mounts and RTABs.

              The trailing arms on these cars are simple. The bushings are rubber and pressed directly into the subframe and knuckle/upright. Inboard should be easy. Outboard might be a bitch due to the casting and difficulty getting a cup/press on it.

                  Cheers, fixed. I think.
