Brake Guru's: R32 caliper "?"'s.

[unwed_transient]

the z32 TT rotors are 30X280.

if that's true, why does courtesyparts.com advertise 32X295 rotors for the R32?

This Cross-drilled, 295mm x 32mm, R32 Skyline Right Front Rotor requires use of the Skyline Caliper required brake lines and adapters and removal of the backing plate.

The Skyline GT-R (R32) brake system will improve the ultimate braking performance of the 300ZX by increasing the brake pad swept area by 6.8% and internal cooling capacity by 82% over the OE front brakes.
NOTE: A significantly greater improvement in internal cooling capacity (136%) will be obtained on early (up to 7/90) non-turbo models as these were equipped with the "small" 26mm brake rotors. These early cars will also require the longer 116mm (vs 112mm) brake pad retaining pins (1 per wheel) (part# 41217-Z32TT).

CAUTION: Some grinding may be necessary to obtain proper wheel/caliper clearance.
Cross-drilled rotors will increase brake pad wear.

or are they just flat-out lying?
