89 240sx with Ladder bar system in the rear

[ETZ Motors]

I was wondering if anyone has a 240sx tubbed out and if so how much of the handling was lost when you changed the rear end?I am currently having a quoat done to have my 240 tubbed out. with a six or ten point roll cage and a ford 9" slip diff in a solid rear axle. I was told that the config should prove to run very streetable but how much so.it is going to be a ladder barsetup with coilovers which are fully adjustible. the reason i am having it tubbed out is so that i can but strip rubber on it or a 12" street rim on the backwhen i drive on the road. this is the first 240 I am bulding the next one I will install the AWD system with the RB26.YOu are prolly asking your self why is he worried about all that traction? I plan to drop a 1000hp motor in this car once the Nitrous spray I don't what to lose no traction.

i'd expect to lose cornering traction a little just due to having a solid axle vs. Independent rear, but with a properly setup suspension it shouldn't cause too much of a problem on the street at all.

Solid axle = unsprung weight, alot of it.

Solid axles also have alot of effect on the way the weight distribution is loaded in a corner. Because it won't allow the individual suspensions to move independently causing it to preload the outter spring by roughly 25%. Your spring rates need to be adjusted to incorporate this.

You'll lose alot of the transient response that the 240 is well known for. You also won't be able to properly setup an alignment in the rear like you can with IRS.

It'd be interesting to hear how you are going to redesign the suspension along with it's geometry to incorporate the solid axle.

Put simply... it'll never have the same handling prowess of an IRS 240.

But it'll be a drag car... so good luck.
