I wanted to make a thread and I need peoples help to minimize my searching time and help everyone out when they are looking to buy one. Please correct me if I am wrong I will try to edit it. I am looking to get a new clutch and it is a pain flipping through so many threads and sites. I helps to make an educated descision based on specs from a consolidated list.
This thread was made to help people when clutch shopping, though I just want facts, and not opinions (there is enough threads out there on that), so pictures are factual, and if could help a purchase, so sure, post them up. and if you don't mind putting up other pics you have found to try and get all the pics in one post somewhat broken down/seperated like I did.
I don't really want to get a bunch of opinions or reviews or experiences with brands ect. in this thread, this is purely for facts/specs/info please. You come here, look at the specs, find what you like, narrow it down and THEN you can do a search on the forum or make a thread to check on their reputation, chatter, and other info that could help you decide.

DMF= Dual Mass Flywheel
SMF= Single Mass Flywheel
I am not going to classify any ALF (aftermarket lighweight flywheel) as that is really subjective. The weights are listed, you decide if it is a SMF or ALF.
PP=Pressure Plate
TOB= Throw Out Bearing
The tool you need for taking the flywheel off is a torx tool. labeled T-60 is the name of the tool. you can pick that up almost any auto store or ace.
Thanks to SoCalturbo, Adamantine, Quartermaster, Snoopy0812, and Tony20tGen, BadBoyBill, whatever210 for their help in aquiring some of the info.
