Ok, so i posted this question AWHILE back and a few people said they would know in a few months so here it is again. Yes, i like to Run the 1/4 its fun for me and the only decent type of legal racing in my area when i can afford it i take road trips for decent auto cross. Now which setup would i see better gains for and enjoy more for a daily driver street racing typeR? is one FD better for the 1/4 than the other?

Everyone says RPM=ruins peoples motors so is there a big difference in the jump in rpm's between JDM and ATS? well any help is always appreciated guys..TIA

 

I would say for street racing the stock final drive is great, but if you absolutely need one, get the JDM... Otherwise, if you are more into autox and tracking your R, I'd get the ATS.
