Exactly that. Why did they put huge seals in the 12a

I'd like to hear from anyone else who has run these seals and later inspected the housings for wear. Perhaps my case is anomalous.

What made you choose the chamfer option? I ask because Glassman mentioned that small carbon deposits build up in the chamfer area.

Based on this, and for what it's worth, I wouldn't recommend running those seals for any amount of time in a non-race engine.

I'm curious about your compression numbers, if you know what they are.

Oem 2mm 2 piece is the way to go unless you are on a strict budget and want to cut corners..( why you would want to cut corners on one of the most important part of your engine, I dont understand) 3mm Oem are a second option if your rotor grooves are outside of spec and you dont want to buy new rotors and cant source a set of used that are within spec. This option does cost more considering the machine work on the rotors and the Oem 3mm seals are more exspensive.. My problem with 3mm seals in general is they cause more heat...yet they are stronger and are more forgiving when you do something wrong..
Better yet take a set of OEM 2mm 2piece and have them cryo threated...
I am pretty sure I have the best price on Oem 2mm and Oem 3mm.. and if you buy in quanity I can even give you a better deal..So there is really no reason to go aftermarket unless upgrading to Ianetti or NRS..

What do you have to say about the RA seals you used? Did they actually break on you? Was housing wear bad? How many miles did you put on the seals? And did you use the RA Classic seals or their upgraded super seals?
