In Reply To Leader gears 4.10 on MT TT. Benefit or mistake? posted by Gunter_Prien on August 04, 2005 at 12:38 PM
     
Message First off, yes, the end ratio is barely different than the NA rear end and that was the point. The goal was to get the same or close to the NA gearing without A) the hassle of swapping the entire subframe B) having to use the weaker NA axles C) having to change the other supporting hardware (i.e. the power steering res, etc).

All that has to be done is drop the diff, have an experienced shop install the gears, pop the diff back in and you're done. For most people (except those that can do this work themselves, which are very few), this ends up being less money, less downtime and less hassle (read: bloody knuckles) for the same end result. Well, plus better axles :) This isn't a big deal for many since only a few people have broken NA ones, but it's still a nice benefit and peace of mind.

As for the gearing itself not being beneficial on a MT TT, a lot of people would beg to differ. Sure, you're going to have to shift sooner but if your car goes that much quicker, isn't that to be expected? Even with the mathematical differences in gearing, it's a "well worth it" trade-off people have opted for for decades. Gearing is nothing new, as you know, and so far everyone with a set loves them to death. I could go on and on, do the math, etc but the data is all out there already. Search my posts, nixit's posts, Greg Dupree's posts, SirpriZ's posts, etc.

Rest assured, the guys who came up with and facilitated this idea have a long racing background...the math and science was done BEFORE all the money was put up front to have them custom made. If you still have questions, email Mark Leader :)

And before anyone mentions how cheap Mustang gears are in comparison, read this

amount of stupid people and stupid logic that dominate Twinturbo.net today."
