Very budget track build
Clarkj93:
New front brake setup Bedded in, pedal feel is good, slight gap of no brakes compared to the gti setup as in its a longer pedal but if I wasn't expecting this I may have not noticed as its very slight. Surprised how noisy the j hook discs are, not that it bothers me but I know VBT have made alterations to make these quieter so can only imagine how loud they could have been. Looking forward to testing this setup out in a few weeks at Pembrey, don't think I'll really get to see the difference until I'm on circuit again.
The pad size difference is quite subsantial
Ebc bluestuff on the rears have worn very fast, 2 track day and maybe 500 road miles and they've got about a 1 track day left in them, I'm swapping them to use as spares now and going to install mintex m155 in the hope they're more durable as I've heard.
Just done an oil change and checked the cam follower, wasn't sure what to expect as it's only done 2k since last checked and maybe 3k max on this follower but a lot of the miles have been hard miles but it's still like new
Got bored and decided to paint the wheels, not meant to be perfect as I cba sanding down tiny imperfections as long as its looks half decent I'm happy. Meant to be satin black but it's come out as Matte instead, still looks decent anyway I think

Yeah I couldn't get on with that dead spot at the top of the pedal. Where it's most noticeable is dependant on how it's driven and is subjective, but for me it was when cruising at 70ish and someone pulls out on you, and you just want to scrub about 10mph off.......nothing :grin: I mean, it's not horrendous and just needs a firmer press on the pedal, but when you do 80 miles a day with that.....yeah.....it gets annoying :grin:
J hooks are noisy are they? See, other folk who've used them have never mentioned that :grin: I did suspect as much as grooved discs I've used in the past made horrible grumbling noises, and the drilled Clubsport S discs make a ticking noise as you pull up....kind of like a cricket chirping away. Anyway, old man gripes aside, I'm glad the mods are working out :happy2:

Awesome day at Pembrey. Never been before but a really cool circuit and very technical. 31 degrees most of the day took its toll on me and the car a little!
New brake setup took some getting used to, trail braking requires a heavier foot for these calipers on the mk5 master cylinder which feels a little wrong at first but with this setup with pbs pro race on the front and mintex m155 on the back it really shocked me how much quicker it stops when the pads and tyres are warm, felt wicked out braking a lot of light weight and better prepared track cars in a 1.4 tonne fat boy golf with heated seats and air con :grin: temp stickers show 140-160 on the calipers which is much lower than before but with it getting hotter and hotter and then getting carried away and staying out far too long on the last session they got seriously hot, didn't help that it was so hot they didn't cool down that much between sessions either.
Will check how the pads have coped and maybe bleed the brakes just in case but it all feels fine still on the drive home tbh.
Weirdly bumped into the guy who did the geo for the golf there while he was supporting a customers race car for the day. Embarrassingly he pointed out that I had my directional tyres facing the wrong way :doh: for some reason I never clocked that if you swap sides they they face the wrong way :grin: they've been like that for ages as well, I've been wondering why it's felt so twitchy on brakes and turn in lately :grin: As you can imagine turning them the correct way meant the car felt a solid 2 or so seconds a lap faster, just way more grip everywhere and much more stable in every respect.
Did feel a little softly sprung in places, not sure if I can get some stiffer springs to fit the top mounts as it takes something like a 4 inch diameter spring on the mount and the shock body takes something like a 2 inch diameter. I've not seen anyone sell custom rated springs that vary in size top to bottom. Adapater needed? Or suitable top mount needed instead?
On way back though its misfiring very badly, cylinder 1. Smell of fuel outside the car and and not plugs or coils so I'm going to assume the fuel injector is dead. Not done the inlet manifold before, it looks a not so fun job.
My winter mod list keeps changing as expensive life events are taking over but thinking the aim is to get about 100kg of weight out of the car without losing air con or carpets yet to stop the cabin getting too hot and Poly bush everything with super pro. No way I'm paying for spherical (...yet?) And the rubber ones are old as he'll and a bit like marshmallows I think as it does feelt a little soft.

What's on the car at the moment? PSS9? Sounds like you need more damping than spring rate. If you add more spring to the same dampers, it will just get bouncy and feel worse.

Yeah, rebound on them is stiff but compression is soft, that's why I opted to keep the rear bump stops full length rather than trimming as most do in the hope this may have the effect of stiffening rear bump up to keep weight over the front when on the power. What you're saying would make more sense with my previous findings, I was hoping going just a smidge or 2 on spring rate would help but yeah maybe you're right there..
I do actually really like the default settings for these dampers and got one hell of a deal on them at the time but starting to wonder if they were a mistake not having adjustment. Maybe just some ARB tuning would sort. currently on mid on the front 24mm whiteline and full hard on the rear 24mm whiteline. I'll try the front full stiff next time, maybe a stiffer front bar and even rear is needed in future.
