i have heard the rumors about the 2k1 being just a bit faster but i am not convinced. my friend has a bone stock 2000 gt and him and i raced once and with all the mods in my sig we stayed the same pace nobody pulled. now i had almost no traction but he said he didnt either. i have driven his car numorous times and it does fell just as strong as my GT with the bolt-ons. mabye i got a friday car, or cant drive worth a crap.
