doing a quick calculation: Rodshop kit is $495, a decent master cylinder plus booster is $700/1000, disc and calipers $1500 (Wilwood on Rodshop website), plus some extra for hoses and fittings and maybe bearings.
I can probably find a cheaper disc+caliper, maybe around $1000?
It seems easy to get to $2500/2800.
thanks for the Hoppers Stoppers contact, I will check them out.
