Kooks LT's fitment problem My friend and I tossed some kooks on my car last week. The passenger side header is close enough to the kmember/a-arm to cause a vibration. Has anyone else had problems like this? I have some prothane motor mounts I'm going to toss on this week, my stock motor mounts have 75k miles and ~500 1/4 mile passes on them, maybe that will lift the engine back up the 1/8" or so I need.

Yeah, toss those new motor mounts on them. Also if you need to, look at the tranny mount and get a poly one as well. I havent' heard anyone experiencing any problems with vibrations, just the y pipe banging the floor, which is solved by the motor mounts and possibly tranny mounts if they are bad.

What size are they, my 1 7/8 were one hell of a tight fit and did not go in easy by an means. Compared to the 1 3/4 that just slide in. There's a big difference in fitment issues. Just letting you know.

I have stepped headers and I had to raise the motor on the drivers side to get that one in. Mine is real close to the K-member on the passenger side as well, not hitting, but thought it might when I went WOT. I ground the lip down on the K-member just a little bit to be sure it wouldn't. Poly mounts will help reassure it won't hit as well..

Out of curiosity, can some of you look under your car at the passenger header and see how much clearance there is from the back side of the K-member and the header tube? Mine was like 1/8" space. Of course 1 3/4" headers are gonna have more room, but I can figure that in from my 1 7/8"..

Mine are 1 3/4, they went in fine, I had to have my friend finish up the job cause I had to work, but I got under the car to finish up the tq arm and didn't notice anything. I had to go to the exhaust shop to get my 'custom' catback fitted to the y-pipe, that is when under the lift the exhaust guy and I noticed how close the header was. I felt vibration from the car, but was pretty sure it was my not completely attached y-pipe and the mega exhaust leak. After a closer look, we realized it was the header. The mounts will go in tomorrow so hopefully that will cure the problem.
