[s-cars] 16" Avus wheels and ECS Stage 3

[Steve Marinello]

You will find that actual 993tt rotors may be hard to come by, if you want
Made in Germany items.  The original rotors on the cars are, as yet, thus
sourced.  The replacement items, even through the dealers, with Porsche
p/n's, are another story.  If Chinese parts on Audi's, why not on Porsche's.

When does the Mayan calendar end?

I'm not so sure about the ECS Stage 3 rotors being 993TT either - if go to
their website & click on the brake kit, then again on the individual items
describing the rotor rings, they come up as "replica" 993TT rotors.  
I'm losing confidence in ECS - seems like the information should be
consistent and clear, but they've got a bit of a hodge-podge going right
now.

FYI, the current ECS Stage 3 setup no longer uses 993 TT calipers but their
own brand or something like that, the kit still uses the larger 993TT rotors
and ECS hats.

The ECS Stage 2 setup uses 993TT calipers but with smaller 314mm rotors (A8
maybe?).

So the old "true" 993TT stage 3 kit using 993TT calipers and 321mm rotors is
no longer available at ECS, I think it would have fit in between their new
stage 2 and stage 3 kit.
