you can get new rearsets that have the option for gp pattern...but im pretty sure you can change the pattern to any rearset including stockers with the right spacers and linkage and i believe sato racing sells the splined connector to the shifter that gives the right spacing for gp shift..i think not sure though....
I would prefer not to do new rear sets since the position on the stock ones suit me just fine. I'll look to see if Sato makes linkage that works OK. Thx.
