and I assume yours work fine?

EDIT: There is one slight problem with the Wilwood D52 units. They use a 7/16 x 20 banjo bolt so my existing flex lines would need to replaced or reworked. Not a big deal I suppose.
Yes, mine work fine.

As I noted in my comments, the total piston area of a Dynalite caliper is 9.62 in2 (2.4 in2 x 4). Wilwood's website shows them as 4.8 in2, but if you do the math you're realize it's actually double that, as I've calculated. BTW, I have an email thread with Wilwood about this, and my calculations are correct. I have no idea why they haven't corrected their website.

With 4 x 1.75" pistons the Dynalites actually have 53% greater piston area (9.62 in2 / 6.28 in2 = 1.53) than the Wilwood D52 calipers (2 x 2" pistons).

As to brake hoses, they're relatively cheap, even the SS ones. Pick your brakes, then go from there.
