Hey guys my s2 started having weird vibrations from the rear when i get on it and in high speeds and I have no idea what is causing this. Also my car grinds 2 and 3 sometimes if i dont do like a delay shift. It has a new clutch and flywheel. What do you guys think.

 

How long ago did you install the new clutch and flywheel. I know some require some sort of "breakin in" period don't they?

 

like a month

 

When people put a new clutch in particularly after market most seem to experience a buzzing type of sound for the first few hundred miles or so. Generally this lessens overtime but it depends on the type of clutch you put in and how many miles you've put on it since install. Don't mean to sound so vague but I'm trying my best with what you're sayin and what I've researched. Lol

 

What transmission fluid are you running?

The vibrations could be a number of things... There's a good chance it's your axles though. Do some research into axle or drive shaft spacers.
