Pros and cons!
Thanks Paul

Yes love them. Part or all of the reason they seized was the use a cheap bleeders after they were refurbished. The proper AP ones have a rubber seal to stop salty water setting to the threads. The company that refurbished them had a 4 year warrenty and fixed them from free as well as fitting the proper AP bleeders.

The brakes are amazing. I ahve the 355mm x 32mm discs with 6 pot calipers. Solid pedal on road or track; large enough to get away with soft street friendly pads at the track without melting/fading them.

I currently use PFC Z rated and used Cosworth streetmaster in the past.

The only real con was the initial cost but in the long run discs and pads will last longer and probably cost less to maintain.

Discs are expensive (I paid £375+tax+shipping) for a pair in sales but pads are cheaper than stock in most cases ~£80+tax. However discs will last a very long time.

Pads I did about 6 trackdays and about 5k road and the streetmasters were 50% worn and the disc less than 20%.

Stock brakes a set of Project Mu HC800+ could last two trackdays, Project mu Clubracer would last about 6 trackdays but you would need to replace disc and pads at the same time.

Sorry its late but hope that helps.

On the Cosworth front I have been running the smaller pulley for about 18 months ~6k miles and everything is running nice still. I am about to do a big service including the belt; just ordered a gates 6PK2315.

Anyone put the Cosworth on a 2018? Some things say it fits, some say not

Why wouldn't it fit? Engine is the same.

It will fit but the air filter won't fit. You have to order a different one. Also, the intake tube is too short so you need a coupling.

The question was more about engine bay layout and if everything will fit physically in the same space

Ok that makes sense, thank you! What year is yours? And does it have the Cosworth in it?

2016 and yes, I have the Cosworth supercharger.

It will fit the 2018 just fine, but you need a different air filter as they changed the air box. This also makes the metal intake tube just a little too short so you need a coupling to join it to the air box. All the information you need is in this thread.

I have one on a 2017 and it fits without issue. As sly noted the fit of the coupling to the air filter box is on the short side. It works but just needs another inch in length to feel confident it won't come apart due to vibration over time. I went with this one: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

You guys rock! I hope all remaining kits aren’t gone by the time I can get my hands on one

I have noticed in the last year on my car when idling, if the AC comes on or whatever and revs dip a tad I get a squeak. It sounds like it could be a bearing or possibly belt slip squeak. Not sure but it doesn't do it when solidly idling and not when driving.

I wondered if anyone here had or has a similar issue?

Back when I had my Cossie kit on my FRS, I also noticed that. I thought nothing of it since it only happened when the AC kicked on and it didn't seem to have any negative repercussions. I think it was just the AC compressor, but it could have been something else, I wasn't certain.

Mine does it when I shift hard at high revs or let the engine bog down pulling out in first. It's belt slippage, for me.

Do you have the undersized pulley? If so, you need the undersized belt. I have the undersized belt and it still slips a little. It's a result of the narrow belt OEM used. The supercharger pulls hard against it.
