BRZ-123 174 Report post Posted July 18, 2020 Very sensible. Anything north of 300 is a risk worth avoiding. Cosworth suggest 280 to be safe and has been extensively researched by them.Watch this video to know more MartinSent from my SM-G970F using Tapatalk 2 Subota Boy and MartinT reacted to this Share this post Link to post Share on other sites
MartinT 514 Report post Posted July 18, 2020 That's a severe engine test - 50 hours WOT from max torque to max power and back again. Real-world driving will never reach those levels. Mark told me he monitors cylinder pressure and maps with the O2 sensor on the rear banks, which are more prone to knock. I'm also careful never to labour the engine at low revs. Share this post Link to post Share on other sites
BRZ-123 174 Report post Posted July 18, 2020 Agree. Its the worst case scenario test and your car never hits the tracks so will not see extreme conditions and you should be safe. Matt / Cosworth himself says that there is room for more but we keep it safe for who we are. It is this over engineering and commitment to R&D that I love about Cosworth and their commitment to stand behind engine warranty with their own tune. If you ever feel like, you are welcome to borrow my Ecutek to datalog and check if you experience knock on your daily drive.Sent from my SM-G970F using Tapatalk 1 MartinT reacted to this Share this post Link to post Share on other sites

MartinT 514 Report post Posted September 14, 2020 I've just received these bonnet struts from Amazon for the princely sum of £15.55. It took just under a month to arrive, but can't complain. I'll let you know how it goes. No instructions except for a couple of photos on the Amazon page! 1 SimonG68 reacted to this Share this post Link to post Share on other sites

MartinT 514 Report post Posted September 15, 2020 Well, they work! Unfortunately, the left-hand one (looking at the engine bay) slightly nadgers the bonnet closed switch, so I have to do some bracket bending. I'm sure it'll come out fine but I've duck-taped it for the moment to stop the alarm going off. Photos soon. 1 SimonG68 reacted to this Share this post Link to post Share on other sites

Luke 193 Report post Posted October 10, 2020 Any luck bending the alarm bracket to keep the switch working? Share this post Link to post Share on other sites
MartinT 514 Report post Posted October 10, 2020 Yes, by lowering the bonnet and watching the bracket, I've bent it a little so as to just give clearance but allow the switch to work. Share this post Link to post Share on other sites
Luke 193 Report post Posted October 10, 2020 That’s good to know, I think I’ll order myself some as well. Share this post Link to post Share on other sites
MartinT 514 Report post Posted October 10, 2020 I've been researching the best brake setup for my BRZ and come to the same conclusion as advice I've received from various others: I don't need a BBK, the stock brakes are plenty fine for my road-only driving. I then set about looking for the best brake pads I can find and have been advised that PFC Z front pads and Cosworth Streetmaster rears offer the best balance for fast road use. They're on order and I'll fit them when I have all the parts. I don't need new discs just yet and have time to research them when they finally need replacement. Meanwhile, it's tyres for winter use time again. I'm going to use my old Rota 17" wheels and buy another set of Goodyear Vector 4Seasons 225/45 as the last set I used were excellent for general winter use and getting through the snow in my lane. When it's spring, I'll then buy a set of 235/40 Michelin Pilot Sport 4 for my 18" XXR wheels. I'll also take the chance to transfer the TPMS sensors from my winter to my summer wheels. 3 SimonG68, willclarke and AndyK reacted to this Share this post Link to post Share on other sites
MartinT 514 Report post Posted October 14, 2020 All brake pads and front discs (I had another think and decided to do the discs at the same time) have now arrived. Just waiting for brake cleaner, lubricant and thread lock to arrive and can hopefully do the work this Saturday. Can anyone confirm that the OEM 294mm brake discs weigh 7.7kg? They do according to Brembo but I can't find any other information on them. My replacement slotted & drilled discs also weigh 7.7kg. Share this post Link to post Share on other sites
MartinT 514 Report post Posted October 17, 2020 It looks like a good day for doing brakes. I have all the parts, so here we go. Back later... 3 Shippers, SimonG68 and choupolo reacted to this Share this post Link to post Share on other sites
MartinT 514 Report post Posted October 17, 2020 I couldn't do the rotors because, despite my being 'prepared', I realised that I had a 17mm socket with 3/8" drive and a torque wrench with 1/2" drive. So I dared not try and break the 17mm caliper bracket bolts as I had no way of properly torquing them up to 80nm again. Back to e-Bay, 1/2" to 3/8" adapter and 17mm 1/2" socket ordered. I will also pop down to Halfrauds tomorrow to see if they have something useful in stock like an adapter. Share this post Link to post Share on other sites
Luke 193 Report post Posted October 17, 2020 Good idea. Those bolts do feel a little sketchy unless you’ve got a really good hold on them. I managed it with a breaker bar and small extension so long as you’ve got the car high enough. Apart from that the brakes are very easy to sort. Share this post Link to post Share on other sites
MartinT 514 Report post Posted October 21, 2020 I have 17 & 14mm 1/2" sockets now, and 3/8 to 1/2" adapter, too. Hoping for a clear Saturday to get those front discs done. Share this post Link to post Share on other sites
MartinT 514 Report post Posted October 23, 2020 While I hope for a good day tomorrow (Saturday) to get the brake work completed, I've booked some more work and a 50k service with Abbey Motorsport. Next on the list of goodies will be a full set of Bilstein B8 dampers, SuperPro lower arms, SuperPro front/rear bushes, Whiteline ARB front and rear drop links, HawkEye alignment. That should tighten up handling while still retaining driver comfort with the H&R Super Sport springs. I certainly don't want it any lower. I do a daily commute of 80 miles and don't track the car, so it's a case of the best real-world road performance and comfort for me. That will be pretty much it for mods, I'm pleased with the way it's coming along. 2 SimonG68 and Subota Boy reacted to this Share this post Link to post Share on other sites
Luke 193 Report post Posted October 23, 2020 That certainly will tighten up the chassis. Super pro should prevent you losing your teeth over a pothole as well. I would hazard a guess that your trying to get the alignment back to oem with the use of adjustable suspension arms and drop links? Share this post Link to post Share on other sites

Yes, exactly that. Abbey said that the SuperPro would not cause extra NVH, so that's good news. 1 Luke reacted to this Share this post Link to post Share on other sites

Yes, I just cleaned them up with brake cleaner (amazing stuff) and a rotary wire brush on the end of a drill. rotor-discs vented/slotted/drilled rotors and PFC Z rated carbon metallic pads.
