solid rear axle possibilities....

[Farley1225]

using a 02m transmission or another stought tranny, is there even a way to use a solid rear axle?i know alot of dsm guys do it with a ford 8.8 or 9" and 3.31 gears.

i have looked for roughly a day and a half and have yet to find a solid awnser of yes or no.i havent even heard of someone trying it yet.

thanks in advance.

dont judge on the low post count, i havent been able to figure out what email or username i used on here years ago since its been about 3 years since i last jumped on here to do anything besides read.

You can do anything you want, I would assume the hard part would be gearing the solid axle to be comparable to the trans during lock up. That and hanging the axle.

[Farley1225]

thats all i was hoping to hear. ill look into it more but i hope it works.

why would be my question

the DSM guys do it as their drive train is rear biased. The 02m is always going to be front biased.

[Farley1225]

i am lost as to how u think a dsm is rear biased? they are designed with the rear being an after thought. the subaru plat form is rear.......

and why, because i plan on primarily street driving and concentrating in drag racing, so a solid axle allows me more room to set up for launching,stronger just all in all a much better starting point than trying and setting up a irs.

confused, are you talkin of awd with the oe front and a solid rear? or ditching the front axles and becoming rwd?

actually, in either case, your issue is gonna be gears. the output of the angle drive is after the final drive and goes out at a gear ratio of 20/21 (or opposite, i never remember!) regardless, it's damn near 1:1. i dunno much about the solid axles available out there but i have a hard time thinkin you're gonna get one with a 1.05 or .95 gear ratio.

you're gonna need that if you run the front axles in or order to have the wheels turn the same speed and you're gonna need that if you go rwd because otherwise you're gonna top out at about 30mph because you'll have the final drive on top of a final drive....... i know you drag guys want acceleration but this short a ratio might be a bit counter productive!!!

[Farley1225]

The idea would be use oe front and have a drive shaft made to connect to said solid rear axle.

Looking at persay the Audi Tt trans finding a ration to match that wouldn't be that bad at all.

i am lost as to how u think a dsm is rear biased? they are designed with the rear being an after thought. the subaru plat form is rear........

dsm with upgraded VC is 65% rear bias. So almost double the power that the front is getting. the haldex/syncro will always have at best equal power front to rear.

Try to source a rear axle from the latest Euro Cabby with 4motion which is solid and will work.

Thanks Dutch1967

I'd love to learn more about the CADDY solid rear axle.

What I've found today (slow day at work)

Part #2K0 500 051 DD


24,000 SEK = $3626 USD

The above is from a 2010 Caddy 1.9TDI 4-motion.

Any idea what the ratio would be in that?

Looking at the Russian ETKA, it would mate to an 02M style trans.
I don't know what drawing to look at to find the rear diff internal details.

Wow, that's freaky!

For that less money you could probably have a common US solid rear, a gear set and have it modified to suit your needs.
