I was wondering if anybody has tried both. I have Cobbs but it's not installed. Just to hear any body's opinion on boombas.

Thanks. I already have the Cobb one like I said but I just want to see if they differ in any way before I get it installed.

If you still dont have a rmm keep your eyes on horsepower direct as over the next few weeks they will have some new toys on the table as well

I have the Cobb one and will probably be installing that. But Boomba is having their labor day sale so I just wondering if anybody has compared the two, and if one is better than the other.

I bought mine from you, and I will probably will. I just wanted to see, that's all. :)

Yeah I can't wait install the quick shift and bushings. And I'm sure the vibration will be the same as Cobbs.

Installed Cobb's on Thursday, can barely tell any difference with vibration. I wonder how long the bushings on these things last, being subject to all the road grime/salt under the car all the time.

Have never responded to a thread before, hopefully this is correct. After a quick thought wondering if the RMM can reduce torque steer I concluded it will not given geometry, mounting points for engine, front axles, etc. Seems to me it just adds noise and vibration but reduces front to rear movement a little. My orange FiST is a little hard to keep in a straight direction when accelerating hard. I am trying to come up with a way to reduce it. I only have 733 miles on the car and it does not seem like that bothers anybody else. Does it??? Hmmm...

Mine has definitely made shifting smoother. I love mine. I would spend $155 if I had to.

Most of the RMMs I've seen use urethane and I have never been a fan. Too much NVH. Custom Performance Engineering offers one using a different material - EPDM. I haven't seen that one mentioned anywhere but that is the one I am most interested in.

My Cobb didn't add any vibration. Maybe a little on set up but none during driving, even with AC on.
