Ive searched, all I got was someone said they weighed their integra rotors at 14 pounds each but did not mention what model.

Anyways I bought some aerospeed crossed drilled/slotted GSR front brake rotors, and plan to throw them on my 90 CRX si. Well Once I got them here they seem heavy as hell. I am really hesitant to put them off if its going to add that much unsprung weight to my car. Does anyone know where to find the weight of stock CRX si rotors, and the 10.5" GSR rotors. If they are heavier than GSR's then I will just put on the OEM rotors then.
I will get a scale to weigh the aerospeeds and post it up.

Another question, do I really need the 40/40 prop valve to make full use of them?

Thanks for any help!

 

take a bathroom scale to honda dealership and wiegh them,

then post back.

they may look at you a little funny, but it will work and then you will know.
