Dougle_turbo Posted August 16, 2019 Share Posted August 16, 2019 Sounds like a good (and expensive) plan. I keep getting close to pulling the trigger on a Wavtrac diff, but then end up spending the money on suspension bits or tyres or a track day or two. Hopefully I'll get around to it over the winter. Car looks fantastic BTW. Link to comment Share on other sites More sharing options...

Also I forgot I started this thread. Prior to track season we replaced the rear engine mount, added side sills, fresh oil, enlarged brake cooling ducts and added the H&R rear anti-roll bar again. Oh and new R888R tyres, 245 front and 275 rear. Finally tried new suspension settings, softer and lower at the front, and stiffer at the rear. This took some adjusting to, but much better. Craner curbs at Donington is now comfortably 100+mph The winter job list: RSS engine mounts Gearbox mounts More oil De-gunk and clean radiators Cylinder compression check Front splitter build (will take some time) Paint the rear deck properly with the correct paint and wrap Make the handbrake work New PFC brake pads (£££££££££) Future jobs: Limited Slip Diff. Wavetrac or Quafe? I hear pros and cons of both. Winter 'to do' list doesn't sound too wallet-busting / drastic. So you've obviously had no reason to think theres any major work needing doing. Good going after some effectively hard miles i'm guessing ? Good luck with all that. You on 19" wheels ? Standard width too ?: How has the new tyre width worked out ?

jcm987 Posted August 16, 2019 Author Share Posted August 16, 2019 @Dougle_turbo Cheers that was Castle Combe, the photographers there are really good. MSV need to take note and stop taking 20 pics of the same corner on a sighting lap. Let me know how the LSD goes if you get started before me. We were planning on doing it when the clutch needed changing seeing as it will take some time. Link to comment Share on other sites More sharing options...
jcm987 Posted August 16, 2019 Author Share Posted August 16, 2019 @sevenfourate Yeah not too pricey compared to last year. No I'm on 18s, 8.5 and 10J. The tyre setup is perfect for the track, but I use the stock wheels on the road. Link to comment Share on other sites More sharing options...
jcm987 Posted September 1, 2019 Author Share Posted September 1, 2019 Splitter finally done. I planned this a year ago, but finally got round to it today. Still a few bits to modify, but I'm happy with how it turned out. And yes, it will take the weight of a human standing on it, so it should be functional and help balance the massive cup car wing. Side note: We discovered the car was crashed head on by the previous owner Slightly cracked front impact bar, dented chassis and a bumper with date codes 3 years after the car was manufactured. The good news is the air con radiators, coolant pipes were changed only 3.5 years ago, so maybe it was a good thing? 1 Link to comment Share on other sites More sharing options...
BenH Posted September 4, 2019 Share Posted September 4, 2019 Really cool build this. Had spotted it a few months ago on Instagram. Looking to pick up a 987.1 S very soon to replace my M235i as my track car, so will be headed down a similar path to you. Link to comment Share on other sites More sharing options...
jcm987 Posted September 4, 2019 Author Share Posted September 4, 2019 @BenH Cheers. Interesting you're looking to replace the M235i, I was very tempted by one because of the BMW VLN 235i cup cars and that engine. Link to comment Share on other sites More sharing options...
BenH Posted September 4, 2019 Share Posted September 4, 2019 @jcm987 Don't get me wrong, very capable car just not a very fun & engaging drive. Could probably set faster laps than a Cayman but just fancy going back to a manual and try the mid engine, N/A layout. The M2 would be the one to have if you were to go for the BMW route.

jcm987 Posted October 18, 2019 Author Share Posted October 18, 2019 Back from a soaking wet, yet amazing day at Brands Hatch. Thanks to Michelin Pilot sport 4 tyres the snappy Cayman is tames, I now can't wait for wet track days. Also Driver 61, Scott Mansell driver tutorial on driving the wet line was so useful (and free). The tyres are incredible, comfortably the fastest car all day even lapping race cars to the point 3 people asked for passenger laps. I'm probably late to the party with the pilot sport 4 tyres, but Im just amazed at how good they are. The original purpose was to test the new front splitter we made, but torrential rain made that difficult. Although the car now makes a nice rooster tail at high speed, so clearly it works. Also when the track dried out and I put the semi slicks on, all understeer is gone and I accidentally set one of my fastest times. It may be home made earo, but now the cup car wing is balanced. Next to make a diffuser from scratch... how hard can it be? Link to comment Share on other sites More sharing options...

jcm987 Posted December 16, 2019 Author Share Posted December 16, 2019 Salty Gritty winter roads: Found myself behind the bloody salt gritter on the way to Brands Hatch and after the track day noticed the car had collected around 3kg of salt/dirt. It was so thick I had to scrape it out of the brake cooling ducts, radiators, suspension and even the air vents, not ideal for a track car. Even the exhaust tips turned powder white. Has anyone else come across this in winter? Link to comment Share on other sites More sharing options...
Wanderinwurzel Posted December 16, 2019 Share Posted December 16, 2019 looks an awesome build JCM987 and plenty of inspiration for my build, the exhaust tips almost look ceramic in that last pic 😉 Link to comment Share on other sites More sharing options...
jcm987 Posted December 30, 2019 Author Share Posted December 30, 2019 The winter build has started. Took the plunge and ordered a Quaife LSD, new clutch, track rod ends, oil seals and brake pads. £££££££££. Just started preparing to take the transmission out ready for the diff and new clutch, not something I'm looking forward to. In the process found a broken rear control arm, didn't see that coming. Suspension turned out to be an easy fix, just a new adjustment cog and pliers. Still not sure how it broke, but found it stuck on maximum bump stiffness, so should have completely unsettled the car. This is going to be a long process so no track days for quite some time If anyone has advice on the best way to take the trans out give me a shout.

Popular Post jcm987 Posted January 14, 2020 Author Popular Post Share Posted January 14, 2020 In case you wondered what a Cayman looks like without a gearbox. Quaife diff arrives next week and then the daunting task of putting it all back together begins. Reading other build threads I've noticed all the US Caymans seem to be spotless and clean underneath! Maybe it's the weather, but seeing as this car is kept in a garage, the dirt, salt and grime collected is unreal. Probably spent hours simply cleaning, probably 2kg lighter now. 2 Link to comment Share on other sites More sharing options...
Popular Post jcm987 Posted April 2, 2020 Author Popular Post Share Posted April 2, 2020 First drive after hibernation done! Total work included: Quaife LSD, new clutch, PFC brake pads, oil, suspension geometry, RSS semi-solid engine and gearbox mounts, SOLO 2 lap timer, thorough underside clean and of course the CaymanOC stickers. Diff and engine mounts make the car feel so much better in every way, it's actually difficult to describe. Obviously all track days are off, so won't be able to put to the test for a long time. I'm right behind the non-essential travel at the moment due to Covid 19 and will not just go for a drive, but that has presented an issue. My daily Fiesta ST is broken, so I need to occasionally drive to work (otherwise working at home). So far two Police cars slowed down and pointed at me on my way to work, perhaps assuming I'm out for a hoon, but didn't pull me over. I removed the giant wing in an effort to go under the radar, as you can see in now blends in! On a serious note, hope everyone is keeping safe and well. 2 Link to comment Share on other sites More sharing options...

peteslag Posted April 28, 2020 Share Posted April 28, 2020 Loving this thread, lots of good information. Thanks for posting. Just a quick question about your baffled sump. Did you fit baffles that bolt to the existing sump, something like this: https://www.pelicanparts.com/More_Info/997107243EBSRK.htm?pn=997-107-243-EBSR-K Or was it a completely new sump/baffle arrangement?

jcm987 Posted April 28, 2020 Author Share Posted April 28, 2020 Hi @peteslag Thanks. No I have a deeper baffled sump similar to this one that replaces the existing one. https://www.design911.co.uk/fu/pt856_859_2371_-cma81-cmo121/Porsche/Cayman-987C---981C/Oil-Sump/ The actual one I bought is from FVD Brombacher, but can't find it one their website anymore.

peteslag Posted April 29, 2020 Share Posted April 29, 2020 That was the other one I was eyeing up actually, thanks for getting back to me. My car is almost completely standard so I think that will be sufficient for my needs. My first few track days were on old cracked bridgestones so not much chance of high cornering g. My next few will be on brand new PS4's so it will be good to have peace of mind. I'm at the Silverstone Porsche club track day in August, can't wait!
