I'll be running a batch of the original washers if anyone's interested

If you make a batch, count me in

I'll prob have 5 or 6 sets available in a few weeks. There is however NO WAY I can meet the old pricing offered here years ago as machining rates/material costs have gone up significantly since then, these will also all be made here in USA with local sourced material as well. I'm thinking pricepoint will be around 50-60$/set.

The piece is simple but without running like a batch of 1000 pcs the price is going to be "high" for what it is.

It is what it is, let us know when you get the washers, I'd like to purchase a set as soon as possible

cchen9_ · 04-26-2022, 04:55 PM

Spacers are ready. I have 5 sets available.

Can anyone comment a little more on the NVH increase with these? Specifically in noise. Currently running Ohlins R&T, TE37SLs, and RS4s. I'll probably also add solid subframe bushings soon. Looking for some more rear stability/directness with a minimal NVH hit.

After 1.5 years and about 8k kms (damned pandemic) there's no change to my initial review. No noise to report of, and I've been beating on them in the hills and at track. Some additional stiffness as per the original review but the Ohlins DFV soaks that up nicely. Before the rear sphericals I always felt the Ohlins R/T were a tad undersprung for track. Now they feel perfect.

Solid subframe bushings are a must must do. Zero NVH.

Thanks for the longer-term update Redd. I was about due for a suspension refresh anyway, now I'm looking forward to throwing these in too.

Also, thanks again cchen for the washers!

Anytime, if there is more interest I will run another batch. Just ordered all the parts to do it myself, should be tackling in a week or two.

All dimensions are in mm

Seeing as how the UK guys use the Mcgillmotorsport ones with no problems, I don't think you'll have a problem with these.

I was finally able to set it all up. Many thanks to this thread for its references, it has been very helpful and I have had no problems during the assembly.
On the other hand, the washers that I found in the text I quote fit perfectly.
After a few days I can say that 0 noises and very happy with the change, along with front spherical bearings and solid subframe bushings the change has been spectacular. Highly recommended

In my case I also have the ohlins suspension mounted and I couldn't agree more with Redd!

Your opinion is exactly the same as mine.

daarts · 05-24-2022, 05:20 PM

Thanks for the feedback Rochen_00. Getting more and more excited about the swap!

Also, good to know there is also a consistent source for these washers for anyone tackling this in the future.

Anyone run Rogue bushing instead of the Bimmerworld one? Looks like these just press in without the need for any retaining compound/tack weld. Lower cost as well. Only downside I can see is that it is not a sealed bearing but for me at least, not really a concern.

Nice find. Interested to know this as well.

Also see that Fall-line jumped on the bandwagon and has one available now. States same as BW; tack weld.

Exclusivs · 06-06-2022, 05:07 PM

Side note: what bushing press/tooling you guys using for subframe inner spring arm. TIA!

If you have the BAV Auto tool used to press all the other bushings out, the #3 cup in the toolkit works.

Please post some pictures and a review. I've been eyeing these and debating between them and the BW ones.

So I just pressed the OEM ones out. The cup fits perfect but the receiving end does not, the two sizes are too small also too tall and interferes with the connecting pipes. So you'll need to mcgyver a solution. A PVC pipe spacer would work I think, not what I did though lol.

Millway also has these available, as well as eccentric bushings for RC and BS correction on the rear axle.

Are you using the Millway?

Currently have them awaiting install

I am. Millway's camber arm bushings on the subframe side, the eccentric bushings on the hub side for the camber arm, as well as their solid subframe bushings to go along with Sidem spherical bearings in the trailing arms.

Also the full SPL package front and rear. Essentially all chassis/suspension bushings are solid aside from black poly RSM's.

Group N engine mounts, stock tranny and diff mounts (though these will likely change when I change my shifter and diff)
