Thinking about it though it would make a great 'sticky' thread listing torque setting for various components. Thanks Tony. I have googled extensively without coming up with much definitive info for the 987. There's plenty for the 986 but not always clear whether it's transferable to newer models. Likewise i've found some info for 996/997 - i assume much of the 997 info would also be correct for 987 but it would be nice to be certain. I agree about the sticky - i'll put another thread up and see what info we can get. Link to comment Share on other sites More sharing options...

Thanks Nobbie, very helpful.There seems to be alot more info available for the 986 than 987. Question is how much is directly transferable but this is at least a good starting point. Strange that the 986 manual has this info but the 987 manual doesn't as far as i can see! Link to comment Share on other sites More sharing options...

If the suspension setup is similar, then I can't see how the torques will be substantially different if using the same bolt sizes.

Buzzlt Posted September 12, 2019 Report Share Posted September 12, 2019 My spanner in the works so to speak.! I have down most of what you are up to....see FYI I haven’t read my post but the 987 coffin arms are the same as 986 ones with different bushes at the front. I know this as they have the part number cast into them. However I have (some of the time) been chasing a slight snooker ball type knocking from the front too and the only thing I haven’t changed is the tuning forks. Given the age of the car mine had 94k once, you will find a big difference if you change the coffin arms and get the geo done. I took me ages to find the part numbers too but If you had maybe googled as above ??? Eporshe are excellent aka whatever and you would do well to buy from them. They get my car once a year for a check over although as the knocking is only slight they have never found it. I did do all the geo myself though so it drives how I want. Good luck.

Rooose Posted September 12, 2019 Report Share Posted September 12, 2019 Started my coffin arms, drop links and tuning forks today. Drop links done but i had to give up because i just couldnt get the coffin arm to chassis bush bolt to budge. Nut is off but it seems to be seized in there! Any tips from anyone on how to get it out?!! Link to comment Share on other sites More sharing options...

Any tips from anyone on how to get it out?!! Not much help but apparently they do that. I was lucky. Plenty of penetrating oil and leave it overnight. Which one? Obviously an impact wrench might free it but how to get it in there. Rears you might. Not far from me are you but am at Goodwood for the weekend so not much I can do to help.

Rooose Posted September 12, 2019 Report Share Posted September 12, 2019 Not far at all, I know Whitehill very well- spent my formative years very close by. Unfortunately I am now away with work until Sunday, so will have to tackle it again next week. It is the front, I can't see any way of getting any kind of power tool in there! Yes, have liberally applied penetrating fluid before I left, hoping that might do the trick but as they lay horizontal, I am not positive it will do what is needed. Thanks for the offer of help and enjoy Goodwood! If there are any more ideas, would be very glad to hear them Link to comment Share on other sites More sharing options...

It seems that everyone buys Coffin Arms like they are going out of fashion. I can see on a diagram what these do but why are the 'tuning forks' not changed more often? (Or are they?) I'd have thought that they wear at the same rate as the coffin arms but could be wrong. People also refer to 'drop links'. Are these the ARB links? I am also very confused about what coffin arms to buy as it seems that there are numerous versions out there and everyone has a different idea about what fits which model of car. I think I need part number 997 341 053 04. I am heartened by the fact that Max at Frazerpart lists these on his website as I've used Max for parts for other Porsches before and know he's good: https://www.frazerpart.com/acatalog/987_Boxster_Cayman_997_Carrera_Front___Rear_Control_Arm.html#SID=136 Are there other suppliers who I should be looking at? Everyone seems to say that 'Meyle' are the brand to go for. Is it worth trying other brands or are they just a waste of money? (I notice that there is no brand mentioned on the Frazerpart website). And, for my particular situation with a car that is new to me but has 970000 miles on it and no record of suspension work, what would you do? Coffin arms or more? FWIW I had the front subframe almost entirely off last week to change the coolant hoses (this car has really kicked my ass since I bought it) so there is a faint chance that there is something loose there but I slightly doubt it. All advice welcomed. Thanks. I changed my front control arms myself on my 2009 Cayman 55k miles, as I had clonking from the front and it cured it. Parts are about £200 from Design911 for Meyle ones with a 2 year warranty, fairly easy diy job, doesnt require a geo afterwards, just need to make sure you torque up the bolts to the specs. Seems like the next thing I need to do is the front top mounts as a get a creaking sound after a few miles in slow stop start traffic, and the bump stops are perished, I'll get these done at a specialist and a geo afterwards, as the strut has to come out, gets beyond my DIY skills and tools available. To conclude, control arms are a good place to start and cheapish. Link to comment Share on other sites More sharing options...
zcacogp Posted September 18, 2019 Author Report Share Posted September 18, 2019 Guys, Update: the front subframe bolts weren't done up as tight as they should have been (😰). I jacked the front of the car up and put a socket set on everything and one of them (bolt holding the front of one of the control arms to the subframe) was notably loose. I tweaked the rest of them up while I was there and all is now well. It's entirely my own fault as I dropped the subframe with a friend to do the coolant pipes at the front and I was the person who did (or didn't) do them back up afterwards. I think that a suspension refresh is probably on the cards but it can now wait until next year rather than having to be done in a rush .... which is nice. Tony Daniel, let us know how you get on with the Spyder Performance arms when you have yours done. If they are any good then I'll be interested in buying some when the time comes. Thanks for your help. Link to comment Share on other sites More sharing options...

zcacogp Posted September 20, 2019 Author Report Share Posted September 20, 2019 Yeah. Perhaps. But I'm not driving to Scotland so am not worried about torquing the bolts up correctly .... Link to comment Share on other sites More sharing options...
