Hey guys, After I get my cyl heads (hopefully pretty soon) the next mod I'm going to shoot for is to replace my A4 with a T-56 - but I'm not real sure which gearset to go with. I have another vehicle as a DD, so I can be a bit more flexible regarding NVH... I guess I'd like to hear what you suggest, and why...

Thanks!

 

What are your palnned intensions with the car?

 

2.73's.


P

 

i hear 4.10's are the way to go.

 

I did the swap, went to 4.10s from 3.23s. I love them, some harcore pull

I got Motive gears, had them installed by an f-body shop, they don't make a peep, no whine at all

I daily drive mine too, no problems, gas mileage ain't bad (15-17 city/22 hywy)

 

wow you only get 22 hwy? i get 19 city/hwy mix in my A4 with 3.73s.

 

well, i've never done a full tank on highway since I've had the gears, but damn close

with the 4.10s, 6th gear is about 2100rpm around 75 if i remember correctly

 

Basically a "weekend warrior"-type vehicle. I've got one big acceleration-intensive goal for it, but after that, it still needs to maintain a modicum of drivability, as I'd like to take part in at least one of the multi-state "tours" that the magazines put on. I'm also thinking that (just once) I'd really like to take part in the SSCC as well.

So that's what I'm building the car for - a fairly serious street car, that will occasionally be asked to work a bit harder than most street cars... Unless my understanding is way off, the T-56 will allow me to run fairly deep gears (I've thought about 3.73s, but now I'm thinking 4.10s, maybe even 4.30s) in the rear, while still retaining a reasonable RPM at cruising speeds.

Thanks for the feedback guys!

 

If your plans include a healthy dose of HP, then 4.10 gears will make first gear worthless with street tires.

 

In my A4, 4th gear is about 3100 around 75.

 

Thanks for the advice guys. From what I've read, it sounds like 4.10s might be just a bit deep, but I'd really like to see if anyone else has any input.

I'm hoping to eventually get the car down to a (roughly) 3400 lb curb weight -less if I can achieve it- running a rear tire size in the 275/50/17 range. I don't think that a combo like this is exactly "cutting edge", I figure there's already been more than a couple of you who've done this.

Thoughts, comments, suggestions?

Thanks again.

 

If you're going to participate in the sscc you should probalby get 3.42's....

 

Well.. that depends how fast you plan to go, right?

You can still pull off 200mph on a t56 with 4.30s out back at around 5600rpm, assuming you've got the horsepower to back you up...

I can't really imagine too many camaros going faster than 180 at that thing... can you?

 

Heh. Nice thought, but there are no "200 mph" aspirations here, I'm thinking of keeping it in the 140-150 mph range - that ought to be plenty for my skill level at this stage of the game, and I'm not looking to impress anyone, just have a blast.

I'm really wishing that someone made a set of 3.90 gears without switching to a 9" rear - the 3.73s seem too "laid back" (or maybe too close to stock), & the 4.10s seem a bit too deep...

Thanks again for the replies, any real-world feedback is much appreciated.

 

I think what he meant with the 3.42's is there are rules and you can't use a non stock gear. Correct me if I'm wrong, or is the ESP?
