will probably get lighter oils such as 1500wt or 1000wt.. but thats just for fine tuning and making it easier to drive. currently im happy with the #2000wt oil setup just the car suffers abit on exiting corners. will do try keep an update here as i go along..
bottom line, geardiff is a worth to buy for those lazy asses like me. n i keep myself busy on other parts of the car now
