12.19 Wilwood kit for Second Gen

[Skip Fix]

I'm new here but id id a search and couldn;t find an answer.

I see Wilwood now has a 12.19 kit for the fronts of second gen F bodies, compared to their old 10.75, both use Dynalite calipers. Anyone tried them? Track change, wheel fit? Since the factory B cars fit a 12" in 15" wheels I always wondered why the aftermarkets say they won't fit, especially Baer. I could see the 4 piston calipers rubbing the wheel spokes but a not that much taller over the rotor for diameter.

I also wondered about using a different Wilwood caliper that takes a larger pad like the SL-GT or GT III caliper on the 10.75 kit brackets and a thicker 1.25 rotor.

Swapping my 78 Trans Am over from a drag car to cornering again , it has the factory 11" front discs and the 81 factory rear disc setup, fits the snowflake wheels fine ot the 1988 16" mesh GTA wheels for better cornering.

Skip I'm interested as well... I've been exploring the C5/LS1 upgrade vs Baer vs Willwood's 12"s... all of which would required bigger rims/tires.

I've also been exploring the 10.5" rear discs with 79-81 WS6 calipers and change out the front sprindles for the B-body units that use 12" rotors and keep my 15x7 Rally IIs... but I'm not sure if the brakes would clear?

Keep me posted here via email or on PY what you find out/decide...

V/R,

Generally you can find some of the WS6 rear caliper setups. That said the caliper design is a pain. often the ratchet parking brake doesn't work and that is what keeps the pads closer to the rotor.

Since the 12" B cars used 15" wheels I would guess they should fit but I've still got that setup in pieces.
