Brake Rotors

[blkboostedtruck]

all A3's had vented so Jetta Fan's good to go.  

In the united states yes but early MK3 in Canada had a 1.8l 8v engine (pretty much the same as the MK2 8v) with 9.4 rotors (again, same braking setup as the 9.4" MK2 setup) while the US got the ABA and 10.1" brakes from the start. The calipers did have an air scoop on them to help cooling. I picked up a set of MK3 calipers for my MK2


Anyway, regarding the OP's question, you don't have to replace the calipers, just get the thinner pads and it should be fine.

would those air scoops on those calipers bolt on to any other calipers ? or are they for MK3 only?
thanks Duane

I've only seen them on the mkIII solid rotor units. They weren't on the 84, 86 or 90 Jettas nor the 88 Fox I had. At least, not that I can remember.  :wink:

Ya no problem for the help....this is what the forums are for!!!

I just went through the same ordeal this past June. The AAZ Jettas seem to have been blessed with the 9.4" solid rotor with non-floating calipers, similar to the almost the entire mk2 lineup (except some models with vented 9.4").

Basically, in order to run vented rotors you need the upright/knuckle, caliper  carriers and calipers from a mk3 2.0 (K2/GT/Wolfsburg) as well as the obvious rotors and pads. Bearings and hubs are identical throughout the mk2 and mk3s (and I recommend installing new ones) as long as it's the 4x100 pattern.

I think the whole conversion cost me over $500 (with LOTS of new parts, mind you), but the added braking force is well worth the price of admission.
