How important are these parts in a timing belt job??
Im trying to decide if i should get the more expensive timing belt kit or the normal one:
Audi A4 Timing Belt - Audi A4 Timing Belt Kit - 2.8 Liter
Audi A4 Timing Belt - Audi A4 Timing Belt Kit - Enhanced
The difference is just these 3 parts:
Hydraulic Tensioning Damper
Relay Lever
Front Motor Mount / Stop
seems like alot of kits have the tensioning damper
How necessary are those three things? worth the extra hundred bucks?
edit: also, has anyone used this kit? does the water pump have the metal impeller? or do they all have that?

The front motor mount is commonly called a "snub mount" and isn't really part of the timing system. It's included in the kit because you might as well replace it while you're doing the timing belt to avoid duplicating labor. The hydraulic damper should always be replaced, but i'm not sure what "relay lever" they're talkin about. You can definitely get a snub mount and damper separately for less than $100.

The relay lever is on the 2.8 - it takes the push from the hydraulic tensioner and translates it over to the tensioning roller. It is only a simple cast metal piece and seems hard to think it'd fatigue enough to fail but since you're in there and the engine will be destroyed if part of the system DOES fail, I'd just do it along with the rest of the kit. As CCA4 said, the hydraulic tensioner absolutely gets changed. The snub also - you might as well. It quells fore-aft engine rock, and is a pain in the *** to change without opening the front of the car. Since you'll have it open, and an OEM snub is under $7, do it.
BTW, you can save a pile by getting your kit at Volvo Parts, BMW Parts, European Car Parts | FCPGroton.com - I just installed their kit a couple months back on my own car and am perfectly happy with it. Several other members bought it as well. I paid $193 shipped for it and the only thing it didn't include, which comes with most other kits, is G12 coolant. That's $26/gallon at a dealership. Add it on and I paid $219 for everything, vs the much higher cost at Blau and ECS and it uses similar, quality parts.
