IRP vs Coolerworx Comparison

Are you all running upgraded engine+transmission mounts? Sounds like a requirement for a chassis-mounted shifter. The relative motion between chassis and trans has to go somewhere.

I've tested CAE and Coolerworx in parked cars though and the direct engagement feels incredible.

Trans mount for sure. I have a great deal on a brand new IRP shifter right now

I had the Z1 PU transmission mount, but I'm running the GKTech solid mount currently. Stock engine mounts, Z1 PU differential mounts and subframe collars.

My shifter is still rattle free.

I wish mine would have been. I've got the new Pro version I'll be installing when my new motor goes in

New motor, was there something wrong with the old (current) one, or just a need for more speed?

Just a rod through the block Going forged motor now

Why did you switch from the PU to solid mount?

So stiffer transmission mounts are a must, but engine mounts could remain stock? I'm just trying to gauge how daily-driver friendly a chassis-mount shifter is. It sounds like not very :/

I wouldn't be able to answer that as I had the Z1 (PU) transmission mount a year or two before I had the shifter installed. I went from the Z1 to the GKTech (I added the MTec return springs as well) after having the Coolerworx for 3-4 years because I recall someone saying that it would help with the 1st > 2nd gear delay that our cars have. Did it help? Yes, a little. Was it the cure-all I was hoping for? No. Not only that, it also increased the cabin NVH, so it's definitely not for anyone who doesn't want a rowdy experience... I do, so it stayed.

That being said: solid/stiffer engine mounts are not needed, I'm still on stock and I've had the Coolerworx for about 5 years now. Solid transmission mounts are most likely also not needed, but since you're going to be under the car, I'd recommend going ahead and upgrading to a PU and be done with it.
