spl only makes solid diff bushings, haven't seen subframe bushings from them yet.....you may be getting confused with what im installing compared to solid diff bushigns as shown by me in this DIY:
https://my350z.com/forum/engine-driv...?highlight=spl



for us the first time yes.....we just drilled holes into it, THEN forced the saw saw blade through and cut out the center, from there once the center is out, its as easy as the rest of them........

Next time we do this, im using the drill saw bits for the fronts.......we will have the oem bushings out in 20 minutes tops for sure now that we know what to do!

Jason,

When you say a "drill saw bit" I'm gathering you mean a hole saw?

If you notice, those SAW DRILL BITS are designed to where most of the shank of the drill bit is used to sorta "ROUTER or WALK" around using a drill........

You can drill into the bushing, then "WALK" the bit all the way around, slicing sideways! This bit would do wonders on the FRONT bushing where we had to drill a few holes into it, just to pass the saw-saw blade..

It's not "needed" but i plan to have them for when we do ACIDJAKE75's car...

I hope to take tons more pics next time...

Check post #4, those are the bits hes talking about.

Good Job J.

One thing I do is mark the drive shaft at the flanges, this way it goes back in the same way it came out. If not, you may get vibration.

^ yes good point....sorry i forgot to add that....I have an "ARROW" marked on my drive shaft to the paint mark on my pinion flange...........

You don't NEED to remove the drive shaft, but it makes it easy to get it out of the way...

the Drive shaft is Carbon fiber, so if you leave it in the car, ensure you protect it with a
towel as it hangs....not like the pic in post #5 where the guy is cutting the bushings out.

Use a towel like this:

Remember, the W-brace is coming out, so just protect it from damage..

Driveshaft orientation and marking:



Drive shaft/ "propeller shaft" LOL...Torque specs:


Nuts and Bolts are 'supposed' to be R&R after every use...i never have,but I constantly check....my car is a track car, I am always checking things before and after...

^ yes, just like that......Terrasmack pointed out to me that its much easier to simply remove the two pair of nuts with brackets holding the ebrake cable then simply disconnecting it from the rocker -- shown in acidjake's pic.

Like this:

Makes sense, then just leave everything attached at the brakes? Pull subframe with cables attached and ziptie them out of the way?

1st time out driving characteristics:

Okay, so I drove to Whataburger......lol....

Before i begin:
I'll be the first to say that NOISES in general do not bother me one bit. My car has a nismo diff, solid diff bushings, nearly all bushings replaced, spl front upper arms, coilovers and single custom exhaust with HFcats...so my car is loud as it is...

To begin, on the highway the car was great, no unknown vibrations or anything to comment on....

at idiol I did hear some driveline noise, but its hard for me to attribute it to solely the subframe bushings.....

I would hate to say it but this review is premature........ill do more driving when i can...I only Track the car, so ill try and find time to take it out on a few trips, etc...

I'd have to assume that if someone was going as far as replacing sub-frame bushings with solid ones. They should have little concern for noise/vibration.

I'd rather know how the car handles/performs.

Time will tell once you hit the track.

^ Exactly!!!

The car drove and handled well.........it felt just as normal as my car would.....test i want to do are launches and drifts, but i suspect those to feel better....to me the car is very predictable and handles as I expect it too.....

Great, thanks for the feedback. One of our initial testers on these said the launching improved drastically. He used to get a real bad shudder/wheel hop and our diff and subframe bushings helped a lot. We are interested to see what you find when you get a chance to track it.
