Feeler: Batch of 20mm rear, 25mm front sway bars

[szacsi72]

Hi all.

There's really not a lot of options for sway bars for the E28, and the biggest one is "only" 19mm in the rear.
Personally, for a street car, I prefer a bit more bar and less spring.
I am debating making a set of 25mm front, 20mm rear bars for myself. But, since I put in the work anyway, I figured I would ask here, in case someone is also hunting for a similar set. This is not a product I plan to sell long-term, just a one-time batch.

Please note that these sizes both WILL 100% require modifications as the front one will not fit a non-M5, and the rear bracket is weak and needs to by modified. 

I also do not like the style of the IE-kit with the clamps. My bars will be 3, or 5 point adjustable with trough-holes, machined flanges. Similar to the ST kit, but that's only 22/16mm.

A second thing I am considering is making the rear bar subframe mounted, as seen on the E34. Since the subframe is bushed, it will work more efficiently & the kit will require welding and grinding anyhow.

ST is 500$, IE is 545$ and HnR is 1015 EUR (what the hell??)
Based on this, my kit would be similar at ballpark 450-500$ (for the bars! would also make reinforcement kits too. )

Please let me know. 
I would make the patch somewhen 2026 spring.
Item location will be Europe.

I've already got ST bars, otherwise I'd be in the market!

Great idea, the adjust-ability is key. I don't need any more, but hope others might. Why not go all the way with the Dinan spec 27/21mm? I've driven BenGerman's car with them and they feel amazing. 

I am using the bigger ST 25/19 set with the reinforcement brackets welded in, and love the handling with the RD Green springs. One thing that also made a noticeable, more planted feel in the back was changing to the Bilstein B8 M5 rear shocks. (heavier valved to accommodate for more weight in the trunk from the battery etc) Highly recommend! (I don't have the M5 trunk kit anymore- sold it back to The Oracle)

Potentially interested, I'll be following the thread. I'm on stock sways at the moment, could use an upgrade
