Default Mk IV supra shocks in UCF10/11

HI everyone!
I was looking for a long time thread of an UCF10/11 in japan that converted to a 2JZ-TT engine and he was also using the Mk IV suspension. I would like to clarify this. Does the MkIV shocks fit UCF10/11? Thank you in advance.

18's but 19's would have been better. Carried them over from another car. They do the job over stock for now... 245's in the back and 225's in the front

This is the thread you're looking for...post #43. He's in Thailand, and some modification is involved.

Just read your posts. How's that?

Keep in mind that this thread was started back in '01 and a lot of the companies have either gone out of business or have discontinued producing parts for the UCF10/11 due to it being such an old car.

For somewhat cheap roof wings, keep on eye out on Yahoo Japan auctions.

The stock LS headers are very restrictive, not to say it's horrible to free up the exhaust gas. They're a little bit better in design than the SC4, although they use the same engine. The banks 5 and 8 are the worst. Their flow patterns flow against the other banks in front of them. I'm too lazy to take the pictures of them, I have a couple in my back yard, but if you search on Lextreme.com, a lot of their pictures are available.

The reason not a lot of them are changed out is because it takes a lot of labor that equals to a lot of $$. The passenger side is a little bit easier than the driver side. The driver side will require removing the steering column joint in order to remove the header.
