I don't have a 7.2 (yet) but I do have two 7.1's. Last week I was working with a guy that had just bought a new 7.2. He was struggling with getting a larger pinion on his motor. The size of the pinion is limited by the top deck! Fortunately for him, I had a RSD VTD for sale and that solved his problem. Does AE have any plans to address this limitation posed by the new motor/top deck arrangement? I'd hate to think that the VTD is the only option.

I know some people have shimmed the top deck up slightly to help with pinion clearance. Otherwise you'll have to go the smaller spur/pinion route.

He was using a very small spur, less than 90. He was adamant about using it otherwise, yes, he could have just gone bigger to get his ratio.
He was already using 1mm shims under the top deck but that still wasn't enough.

Well, I'm glad you made me go check, I was COMPLETELY WRONG! Right now I'm running a 69 tooth spur and a 39 tooth pinion and it works great. That gives a 3.54 FDR. That's what I run for my VTA 25.5 car. But a 40 tooth pinion won't fit, it will barely hit the top deck. So if I need to run below 3.5, then I need to put on the 66 tooth spur gear. I'm not positive, but pretty sure I could move the motor back enough to get the 39 tooth pinion to mesh properly. That would give 3.38 FDR. Not sure if it's in the cards to get below that unless you run even a smaller spur and then slot the motor mount holes so you can move the motor back more.

How come you didn't come to QCRC for round two of the Tri-State series?

Do the AE x-ring shock seals (Part #91493) need to be soaked or treated in any way prior to use? I'm reading that some of the x-ring seals do and some don't. AE doesn't say one way or the other.
