Dan Norton Posted March 28, 2019 Share Posted March 28, 2019 So after putting in about 1600 miles on my 987S , i love the car....everything about it. I was thinking to myself "do i modify this", and pretty much answered my own question and decided "no...but i'll try and improve bits as i go along" There's really not a lot to improve on, but the one thing i have thought of is....initial pedal feel. It came with brand new Brembo discs and pads on the front, and after bedding in, they really do stop the car hassle free, but i have noticed you do need to give it much more of a prod than most cars i've owned. Maybe its the fact its got pretty big calipers and discs to put some effort in, but either hot or cold it does need more initial effort. Are there any modifications to the standard brake system people have done to help improve this? (everything is bang on with the brakes by the way). Cheers Dan Link to comment Share on other sites More sharing options...
crafty1 Posted March 28, 2019 Share Posted March 28, 2019 GT3 master cylinder will solve that, it is a popular upgrade on a Cayman firms up the pedal nicely. 1 Link to comment Share on other sites More sharing options...
Aaron Posted March 28, 2019 Share Posted March 28, 2019 Are you referring to the pedal travel or the amount of force required to engage the brakes when pressing the pedal? You can reduce the pedal travel, but decreasing the amount of force required is not a possible modification I'm aware of. Increasing the required pressure using the GT3 MC is a solution (if that is indeed the issue). 1 Link to comment Share on other sites More sharing options...
Popular Post Porsched eggs Posted March 28, 2019 Popular Post Share Posted March 28, 2019 The firmer push needed on the brakes is more the brake servo assist which is less assisted than in normal cars. My old Elise was like trying to compress a brick! 2 Link to comment Share on other sites More sharing options...
Popular Post anon_uk Posted March 29, 2019 Popular Post Share Posted March 29, 2019 Hi, I had been in the same situation. Did the GT3 MC upgrade with S/S braided hoses at the same time and it made a big difference to me! 2 Link to comment Share on other sites More sharing options...

Sounds like the GT3 MC is a solution? Link to comment Share on other sites More sharing options...

Thats what i'm thinking here, maybe I've been spoilt with the fact nothing i've owned performance wise yet (FD3 RX7, loads of CRX's, 944, 330i clubsport, S2000, Mini coopers etc) have had massive brakes like the Cayman S as OEM...its different to what i've been used to in the past.

Is the MC a "bolt on" fit, or does there need to be modification? Link to comment Share on other sites More sharing options...

Looking good as my first upgrade - thanks for the heads up. Is it a straight fit? Link to comment Share on other sites More sharing options...

You need Durametric or PIWIS to bleed the ABS pump automatically. The alternative is bleeding the brakes, activating the ABS a few times, and then bleeding again. I also had an FD a few years back - welcome to the refinement! 1 Link to comment Share on other sites More sharing options...
crafty1 Posted March 29, 2019 Share Posted March 29, 2019 https://www.ebay.co.uk/itm/Porsche-911-997-3-6-GT3-Genuine-TRW-Brake-Master-Cylinder/302983408517?hash=item468b37eb85:g:N-AAAOSwfplcBoaJ I have seen them cheaper than this. I did not do mine myself but used a specialist. The biggest problem they said was it was very hard to get all the air out of the system and in the end had to revert to the old fashioned method of manually pumping the brake pedal and bleeding each wheel individually so it took a while but the results are worth it. 1 Link to comment Share on other sites More sharing options...

Good German car specialist garage down the road from me...I'll ask them to do it, but nice to hear it's a straight fit. I adored my FD3, and I don't know why even though it's completely different my 987 reminds me of one (weird I know ). Really enjoying the Cayman, almost 2000 miles in as a weekend car now ! To date the favourite car I've ever owned. Ps...have you see the prices of FDs starting to sky rocket! Link to comment Share on other sites More sharing options...

Lovely....thanks for the link. Might try and get this done before our road trip in May. Link to comment Share on other sites More sharing options...

If they are then good luck getting them off! Link to comment Share on other sites More sharing options...
