Which clutch for a b16a?

I have read you use Teg LS clutch and I have read you use GSR clutch. Napa has the disc size for the LS at 8 7/8" and the GSR at 8 5/8" so which one do I need?

It depends on which b16a transmission you are using.

Y1/S1/J1=90-91 Integra LS clutch
YS1=92-93 Integra GSR clutch

If you are running a 92+ hydraulic trans then you will need the clutch that goes with that specific transmission.
