I love my Delrin subframe bushings!!! The caR just feels much more solid.

 

This was really informative! I might give this a try knowing exactly how to do it on Jackstands, I figured this would have required dropping the subframe.

How does it affect handling though, like in the corners? Can you compare to the IPD poly inserts?

 

I dropped my subframe and used a baby sludge hammer and a 32mm socket to drive it home. Your way sounds quicker.

Here is how I did mine.

Then bolted the delrin inserts in. Easy peasy!!

Similar to what I did but I didn't cut out the center section. Proved to be a waste of time sawzalling under the car for me. Just hammered the screwdriver through the lip then up the inside edge of the bushing and pried my heart out.

 

^is that a spacer you created in the last pic?

 

No it's it a shot of an air chisel taking out the oem mount. I used small blocks of wood to space enough to drive them home. Lol

 

I don't have a comparison to inserts. They do change the handling significantly. Much stiffer and connected now. With the track swaybars pulling out of a dipped parking entrance I get one wheel up in the air. Steering feels less squishy.

These aren't for everyone though. The vibration at idle with the AC on is definitely noticeable by all passengers. Non car people will seriously think your car is going to explode and ask a bunch of dumb questions to prove it.

 

Anyone compare these to IPD's version?

 

IPDs only stiffen up the stock/crappy bushings so far.

I currently have IPD ones, and picked up a set of Kaplenke's delrin ones. If I get around to installing them, I'll try to come up with something.

 

Gonna have my mechanic put them in in addition to the sway bars. What's a reasonable amount of time for him to charge? Another hour?

 

I'm pretty comfortable around my car and I think this one took me a little over 2 hours start to finish.

 

Cant wait to get mine installed...

 

If anyone is looking for a set, we do carry and they ship out same day under most circumstances.

 

Just ordered a pair 😃

 

Im trying the subframe brace instead since it'l be easier. You can have your idle raised if you do a tune. I did and all the vibes from poly is gone

 

Installed mine last weekend....
Let me preface this by saying there's not many mods I wouldn't help another Volvo owner with, but this is one.

Starting with cutting the bushings out:
I tried with a drywall saw, which was futile and painful. Then I went to the dremel with a cutting bit. Painful, but not as bad. Molten rubber everywhere, toxic smoke galore. Make sure to wear a mask. For the next three, I used a hole saw with a huge corded hammer drill (switched to non-hammer mode). Still horrible. Sprays 300 degree liquid rubber everywhere, leaving you with nice burns and impossible-to-rub-off rubber gunk.

Next comes the install:
I'm sure these are very easy and have a very nice locking fit if you put them on with the subframe out of the car with a press. Under the car? Not easy at all. I decided I'd draw them in with the subframe bolts. Slapped my 5' cheater bar on the end of my breaker bar and broke the subframe bolt. Ended up sanding the little locking ridge off the sides of the shaft. Even then, it took plenty of sledgehammer hits to get them in.

I can notice a big difference in acceleration feel, the car doesn't lurch backward like it used too. A bunch of creaks are gone and the car feels stiffer (not as much as everyone seems to make it out to be, but I have the 25mm sways and KW's, along with all the stiffening bits, so I think some of the magic was lost on me).

Would I buy and install again? Yep. But this time with long sleeves and throw-away tools.

What bushings did you install that gave you so much trouble?

 

Yeah, he'll be in doing the sways already. Figured shouldn't be too bad since the subframe will already be dropped.

 

Good to know. Thanks.

These guys

 

That's why you should have used these bushings. Ease of installation, excellent performance.

 

Not seeing why those are easier to install?

 

Because the lip on the subframe is tapered with an opening in the middle. When you are only going one direction it catches on the upper lip, where these insert from the top and bottom and aren't fighting the taper.

 

Ah, gotcha!

 

So, once you get the old ones out, these two piece bushings should pop right in? Eliminating most of the frustration everyone in this thread seems to be having? And the benefits over stock/stock + ipd poly inserts are comparable?

Just trying to get clarification, as I haven't seen these eBay ones mentioned anywhere on the boards recently. Which is why I went with the kaplhenke.

 

They're made by C10 or CJ8 or something that reminds me of a Jeep model. I'm sure they're fine, I'd just rather support Ben, and his were a much better price when I bought mine (on sale)

 

Car should have come from the factory with these bushings. Highly worth the investment. Probably the best modification I've done on the car.

 

Had them put in today with ipd control arms, front sway bar, ipd HD end links...no noticeable vibration above the difference I felt when I put the upper poly ipd mount and lower tranny billet mount.

It is tight. No other adjective describes it.

 

Wanted to note that I updated my original review with the true cause of the vibration at idle. It was the poly lower trans mount that I added at the same time as the delrin subframe bushings. No vibration any more after replacing that with a rubber version.

 

Have you noticed the planted feel when getting on the freeway when the on ramp is a 270 degree turn? That feeling of tire push is gone, surprise!!, it's the bushings not the tires.

Thanks for the review.

 

Cant wait to put mine in, sitting on the ground next to me as I type... my car feels planted now so I cant wait to see what the change is like with these!

 

There is no bushing replacement for the rear subframe right?
