I put KYB's on the front of mine. They are the best cheap performance shock on the market IMO, I've run them on all my Mustangs and such, they perform far better than their price would indicate. They aren't quite as good as something like Koni, if you've got money to spend then something like that might be a better option. But if you're on a budget or just don't want to spend alot KYB's are a good choice. Also, you won't find a part number for KYB's for a TR6, you have to call them and tell them thats what it's for. The shock you get will actually be for a Mustang II, and you'll need to trim the bottom mount bolt tube down a bit since the Mustang uses a longer bolt. If you're interested let me know and I can dig up my receipt with the part #.
