From your description it is STOUT!!! If it only has 22K on it I sure hope you put some miles on it and enjoy it!

I was told the triple disc clutch wont last long on the street. I've never had a car with a multi-plate clutch. Is there a secret to them?

Idk but looks to me that you dont like the vibration you might want to change you motor mounts to new oem stock one. But your car build is well done.

I would certainly sell the triple. I only have driven one evo with a triple but it was not fun. I have an exedy twin hd that is very easy to drive on the street and still holds alot of power. You could sell the triple and get back most of your money. Triples are big $. Other than that it looks pretty streetable to me. What don't you like about driving it on the street? Too much lag? etc..?

Only thing you need is to get rid of your clutch. Once you have an exedy twin in that thing it should drive really nice for the street.

You could also keep that clutch and remove the overhelper spring in the clutch pedal assembly if that QM triple uses a hydraulic TOB. That will make it drive a lot nicer.

The Exedy Triple clutch feels very close to the Twin in term of pedal pressure.
Only thing to spool faster (thus feels nicer on low RPM) is a longer rods 4G64 build. :}
Congrats on a Cherry of a car!

your build looks solid. very street able. I would take it to a shop just to get the tuned checked out, boost leaks fixed etc and voila. learn from there

whats it doing right now that you are saying its not streetable? seems rather streetable as it sits aside from the clutch.

Softer motor mounts will help. You can user softer durometer poly, which are firmer that factory but not cause so much vibration. You can also apply some lizardskin sound control inside which isn't heavy like dynomat. My Exedy triple is very streetable but loud when engaged but you have a QM which is much different and not street friendly.

The car is very nice, I am not sure what settings your dampers are at, but you can find someone local who can adjust it so that it absorbs smoother if it's a little rough on small bumps..

Trying to see if I can get a dyno sheet from AMS. I'm thinking that will give me a good idea on which clutch to get. I feel like it would be a sin to dial it back.

Thanks everyone for all the suggestions, I really appreciate it.
