Below is the 4.88 FD from weir performance.

Sorry if I derailed your thread.

Nice! Sounds real healthy!

Hey @kitlives do you have a video of the speedometer going thru gears? Would like to see what your shift points are with the 5.29 Thanks .

I'll see if I can get one and post it up.

You have to remember the above graph is with a standard 4 speed whose 4th gear is 1 to 1 ratio. Our 6 speed transmissions are over drive so that chart would not be accurate for us.

80 for me is 3100.

Not exactly, that is a chart from Spencer Fabrications page for their BRZ/FRS gear ratio swap page. That is factoring in the correct ratio for 6th. It's pretty spot on.

Boy it doesn't come close to my readings. But maybe they are using the manual trans and I think my automatic has a different 6th gear ratio.

Makes no diff to me. I love my 4.88's.

Automatic does have different ratios on all of the gears, not just 6th. Gears are longer in the auto.

chaoscentral · 02-21-2017, 11:33 AM

oh no I know, but I'm 95% sure that page is geared more for the manual.

Stock is about 3100rpm for a manual in 6th at 70mph, so 3300ish sounds about right with a shorter final drive.

I've seen Lunatic preach this on many threads and I finally pulled the trigger today and installed 4.88 weir gears on my AT FRS.

Simply put, this car should have come like this from factory. Driving around town is a breeze and the car revs and accelerates a lot quicker.

11/10 would recommend. $1100 well spent imo.

I'm glad you like it. I'm still loving mine.
