Shit chassis produced a shit response is the answer. Never driven j30 and I doubt I will ever drive one that is modified so I could not tell you wether it makes a difference but an m35, v35 and z33 is a f$&king way from a j30. As mentioned before a good chassis with show up the slightest of changes in the suspension or chassis.
I might give subaru a ring tonight a give em the bad news that the extra 100 kgs of bracing they put into the wrx chassis is a waist of money.....shit I might ever go and remove some of it from the race car......thanks for your advice buddy now piss of and go spam up someone elses thread with your j30 info.
