Jeeps run axles at different angles with different types of stresses and different stress points. There is simply no comparison between an IRS diff in a jeep used for 4x4ing and one used for a sports car...

honestly this is out of my budget, im thinking a skyline r33 gt-r IRS, we have been racing skylines deep into the 7s with the stock diff and stock shafts/hubs ...

the cross memeber design looks very similar, anyone tried the r200 nissan IRS on the brz yet ? works in the s2000 !

that would be a cheaper option able to handle as much as the 8.8 for sure, especially on a light car !

4wd... Initial launching shock is on the rear axles and slip is detected then torque is transferred forward to help regain traction. Unless an ATESSA controller is used to control/lock a specified percentage.

Most of the guys here have gone 7s on stock R200s,

going 910whp was cheap, a 2jz is very cheap over here, pistons and rods, and titan 272s and springs were cheap also ...

this 8.8 conversion isnt, a v160 for example isnt cheap either, im running an r154, the only thing left is a longer final drive and stronger rear end ..

I think people easily forget these parts aren't for daily boosted BRZs when saying it's pricey. These are 9 second race car parts.

The m85 lsd rear can be gotten for for $600-800. 3.73 rear and has held together on is300's with over 600tq. Then all you really need are axles, as the drive shaft is really just a gimmick for gains in the 1/4.

If you daily your boosted 86, just go with a m85 and possibly DSS axles. You'll be covered at least to 600hp (axle rated limit), and 600hp is beyond most peoples' power goals on a daily anyway due to the stock trans.
