On first gen Jackson Racing (Rotrex) and Vortech were the best performers on the track conditions. JR did not launch for 2nd gen yet and Vortech just launched, not sure what would take to import to EU. Harrop is a good choice too and the updates done for better cooling may be enough to make it...

Would be Ok to add the link here?

Ansix developed a O2W cooler that some people in Canada is running with success. Group is reviewing with them details and suggesting improvements (e.g: using adaptor to be able to use Subaru filter) and/or options (e.g: using Porsche core). Not sure of Ok to add link from other forum here, if...

Finally decided on the brakes. Selected Powerbrakes 325x28 36/40 BBK. Moves the geometric bias rearward a tiny bit (0.33%). Really nice design machined from billet with a top bridge (good for stiffness, not so good for pad changes), clears out stock 18” and Forgeline 17x9 wheels that I use...

I would suggest to zip tie the stainless steel lines, they tend to move and kink otherwise.

Found another good alternative, powerbrakes (South African manufacturer, with good racing background), has a kit with 36/40 piston in a 326mm rotor. This kits moves the bias 0.36% backwards, similar to the Essex AP Racing Sprint (38.1/41.3 in a 299 rotor). This can provide the needed extra...

Overall I prefer setting my cars with a good geometric balance, so I can choose rear pads with lower overall friction and better modulation, that normally allows the ebd to work better, get shorter stopping distance and reduce likelihood of issues. But I am sure others may differ and run...

The 330mm Reyland shifts the bias forward, for a proper balance of geometric bias, requires rear PP Brembos. I do not see a reason to upgrade the rears as I do not see any fade or degradation on those.

Talking to Godspeed, learned that they have a kit prepared for the GC8 that is a bolt on and keeps BRZ brake bias (calculated and update the brake bias file, will upload later here). Would not need to change rear caliper/rotor, saving mass where is not needed to upgrade. Probably this will be...

Thanks a lot! Kind of late for my case, but will keep in mind on other cases. It is a common failure point on the race cara here, so I will see another soon enough.

There are at least 3 different threads, all useful. I would suggest going on order. https://www.gr86.org/threads/i-did-a-dyno-comparison-of-7-different-intake-setups.12304/#replies https://www.gr86.org/threads/intake-dyno-comparison-part-2-sme-headers.12562/...

I heard about that, coilovers are next. May have been a better plan to start with coilovers, but I found a good wheel/tire set for a fair price.

The comparison is versus the oem intake with the diaper removed. He is doing a great and detailed work, with the normal flaws that cannot be controlled. Not sure this forum’s policy on that, if Ok I can add the link.

When working with the dealership, started measuring on flat surface, same temperature, also verifying the smoke on the startup. This was about 3 months before changing. Then changed the valve and measured again. This is one of the cases that is documented to have impact on oil consumption...
