CUSCO 4.55 FINAL DRIVE installed. - Page 15 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

i've made the mistake of going with a shorter final drive once before. it's cool for about the first month. turning 3k+ at 60mph and not having a useful first gear gets tiring real quick. of course this was in a 2400lb miata with 260whp, so i'd imagine here the math is a bit different.

what are you turning at 65-70 in 6th?

i drove my VW Golf for years with the 5th gear well over 3K at highway speeds.

quite normal for a 4-banger as far as i'm concerned...

i don't understand what it is that annoys people about cruising at such RPM's, it's quite low to be honest.

Stock MT is just reaching 2800-3000 RPM at that speed on stock gearing with stock height tires.

That is PRECISELY the problem. At 3500RPM my exhaust sounds great, but I'm going to get sick of the noise after 10 minutes of cruising in that RPM range.

I get it

Slow down? BRZ 6th gear isn't great but it's not that bad, at least you're able to do 60-65mph comfortably. 60mph over here is >3200rpm

And you don't have a soft top, and you have touring Michelins. Though I agree 3000rpm is bad, pretty annoying to listen to unless it's one of those cars where you can't hear the engine at all.

I guess then this mod is not for you... hee hee

I am curious as to what the top speed in each gear is with this mod?

Also what if the redline was 8000 in 2nd gear - what would that gears top speed be? (Visconti tuned)

Look on page 2 at the chart posted. Will somewhat answer your question, but not the 8000rpm 2nd gear limit on the tune.

Expecting my 4.55 FD by the end of next week. Can't wait to check the results for myself.

Still debating. It is for me, I don't know if I can live with it though. I do want to hear more reviews.
