I wasn't aware that tokico had anything for the P10's or any year g20 at all

That's kinda odd. Maybe it's just a OEM replacement. You might wanna ask what model of the tokico's he's getting you and maybe part numbers also. If it is a OEM replacement those will just blow in a matter of time.
Do a search for yourself
www.tokicogasshocks.com the only shocks I saw were for the I30's and Q45's.
I'd get the KYB AGX's, a little more expensive but adjustable dampening, 4 way in the front, 8 way in the rear. Under $400. Probably one of the best streetable combo's (Eibach/AGX)
