700WHP- MT ET Streets on stock 18" or forged 20"
I know the most ideal would be 305 35 18, its what I am running not except on Nt555r. I really want to put my Forgestar 20" to use and possible get some 20" drag radials.
Anyone have any experience on how drastically performance is affected going from an 18" to a 20"? Primary concerned with 60-130 times. Eventually I will get a vbox and compare both sizes.

Your OEM 18" are fully forged, would be a better choice for a 700whp vehicle. There's huge difference between flow form/rotary forged vs fully forged.
If you're looking for track capable fully forged wheels, please let me know. 750whp F80 with Signature SV302S at the Roll Race - 154mph run.
