    Ive seen one convertible snap an axle, and I had a 135 destroy an axle...like inner cup completely gone.


    Thats what launching the car from light to light will do for ya.

    Edit: the splines pictured are in the DS.
    Yup looks like the case with mine

    Got word back today I need a new differential and driveshaft. Appearantly the driveshaft input to the differential is what took a hike same as onebadmofo situation. The difference is I am open diff. Looks like that doesnt really matter and I need to focus on suspension

    It seems that we've found another weak link in the suspension.

    On the Road Again.....

    Got my car back yesterday and just going to chill till I get a suspension and bushings upgrade.

    Will also get a Differential Brace added when LSD gets installed. Thanks to BoostAddict for the reference on this

    Other wise, be careful launching these cars on the drag strip on stock suspension when you have increased significantly the power

    Interesting! But won't this transmit a whole lot of NVH, as this basically bypasses the insulating bushings? I have replaced the rear diff bushing on my car with a Powerflex polyutherine bushing and there is definitely an increase in audible diff gearing whine.

    I have solid bushings, so do I really need this if I want to do hard launches at a drag strip

    The brace pictured above is from a 350z. On that platform we had great success reducing wheel hop, and preventing diff carrier bushing damage. I haven't had a chance to look under the 335 yet to see if there is an easy spot to mount this. This would mount to the subframe in turn holding the differential down. It would not increase vibrations as the subframe bushings would still be absorbing the load. You shouldn't get any noises either. I plan to have @RabbitPusher weld something up soon. If all goes well we plan to produce these.

    when you say hold it down do you mean keep it from moving from side to side correct me if im wrong. The diff on the e9x has 3 bushings if those are replaced with solid ones the diff shouldnt move what also happens is that the transmission bushings are very soft and can have movement which causes missed shifts etc.

    For the price why not have the added support

    Looks like it for that 350Z, however it doesnt mean we wont be able to have double braces for our cars, it all depends on how it will be configured

    Bushings wear after a period, also the brace will reduce shock travel by absorbing it. Thats the wasy I look it

    i have the solid ones and the ride quality is like having camber plates the transmission solid bushings makes the car kinda unbearable thats why i switched my trans bushes back to stock.

    More so, the goal is to stop the up and down motion which will help reduce wheel hop. Stock transmission bushings won't hinder the effectiveness of the brace. This is a way to try and hold the rear end down.

    How is this stuff effecting ride quality? Had heavy duty suspension parts in some street strip cars (more strip oriented) way back when & they were less then fun on bad pavement.

    I've been rolling with solid bushings and the defiv arm for 8 months now, no problems with NVH or harshness. I'm out in PA where the roads are pretty $#@!ty, gravel, potholes, smooth tarmac? Forget about it.
