I was wondering if anyone knows the dimensions of the front(2) and rear(4) shocks on an 87 TR? I am away on business until December and have a chance to purchase some Penske coilovers. I need to get the length, both compressed and extended, as well as at rest. If somebody has that info or is willing to measure some up for me it would be greatly appreciated.

If William H reads this thread he should be able to give ou the actual model number that fits, although his were remote canister style.
I guess I'll find out when I get home in a few weeks to measure mine..........Thanks anyways.......... I guess I should post more relevant questions like, What air pressure is best in the drivers side rear tire for a non- metric tire on a flying mirror TR?............LOL Kerry
The data that you seek is maybe shown on pages F22, F23, and F24 of the TR WSM 330/84 without the upper mounts in place (since the upper rod does not have an "eyelet" style mount, this sort of complicates a simple answer to your question IMO).
I have CAD drawings of the factory shock to the exact spec. We have built 3 testarossa penske setups.
Steve as noted above in my original post/question..........I'm away on business for a number of weeks and did not have my WSM with me. ( It is not an item I tend to carry with me.) That's why I was asking if someone could check theirs, or could do a measurement, or check their WSM. I'm sometimes amazed that this amount of banter is exchanged to "qualify" an inquiry, may be my self induced parinoia speaking here. LI shall take heed and live and learn........iI you want information, seek it yourself and not intrude on others time and expertise. Just thought this was a legit question, with a proper explanation as to why I was unable at this time to retrieve the info myself. Also thought it might be of interest to others in the future. So this thread would offer information for others. Isn't that what this forum is for? When I get home I will reference the WSM and I will post the dimensions. Kerry
Kerry, I wasn't trying to be upset about the question that you asked -- I truly can't answer your question in a few words, and don't have those WSM pages in a postable form (if you want them, send me a PM with an email address and I'll scan/send). Please do post anything and everything related to this in the spirit of being "of interest to others in the future" -- it will be a "project" You've seen the pictures of the installation on William H's 512TR? Always seems that the new stuff is so small that they need to invent/add ways to take up the space. If Robert Hayden's Koni rebuilding place could also add adjustable lower spring perches for not much more in price (and one could get the parts there and back at reasonable cost/effort), I'd do that in a heartbeat.
Steve thanks for the offer, much appreciated. By the way no animosity here on my behalf, I apologize if it read that way, computer text lends itself to being interpeted emotionally by the reader, and trust me I have on many occasion interpeted someones response in a completely different way than they intended.. Harmony PM'd me and so now I have the info and the dimensional info. They have it all in solidworks and can have a set of six ready in about 14 days.........that being said I now need to get the lemonade stand up and running to cover the costs......but I feel between a suspension upgrade and Brembos I will find that the "driving" experience will be well worth the costs. Thanks again for offering to provide me with the WSM pages out here on the road. Kerry
So on the Penske is the force from both the spring and the shock supported by the end of the threaded rod? On the stock TR shock only the force from the shock is supported by the upper mount (with the upper spring perch being part of the chassis). Can you post a jpeg of the how the Penske shock mounts to the TR chassis bracketry -- do you make a special piece?
The threaded rod only holds the wheel up. The shaft itself holds the spring pressure. The reason for this is you get less shock binding. Its operates smoother and provides better damping. It is more cost effective for Ferrari to combine the shock mount and spring perch into one unit.
Figured why start a new thread..............so.............. Are the shocks on an '87 TR, high pressure or low pressure shocks?
