I dunno why pics show up sometimes and sometimes not.

I think I have decided to go h&r lowering with bilsteins ordered from Europe at a shop that has a separate spring for touring...

[restart]

Looking around in Europe where tourings are commonplace.... I see different shocks for the touring vs cabrio.

While we are talking suspension here are e30 vs cabrio vs touring weight/distribution for reference...


I hope pics show up inthread if they don’t can someone post them some external link is not required.

From the bilstein site It looks like the b8s use the same part number
As all the other e30s.

They list 51mm for fonts
But all the rear shocks say 45mm
Does that sound correct.

Nice,
Somebody told me I should get the b8s though
:-)

Bilstein Tourings will be softer, sports/B8/HDs more firm. Since a touring is not a race car I'd go with OE sport springs, maybe verts in the back and Tourings or Sachs Advantage if you can still find them.

New OE springs are also an option, especially if you haul cargo.

I run 6” 1200lb swift springs in the rear with stock bilstein shocks. Drove it like that from Phoenix to Fontana, California no problem still very comfortable.

H&R + billy's will always work, I had them on mine before switching to coilovers, add some drophats for a great daily setup.

I am looking for new shocks/springs for my touring and wonder....
Any recent updates, new info, from touring owners that have gone to H&R/Bilstein combination?

Speaking from experience, you for sure need heavier duty rear springs for a touring, and/or possibly longer springs.

I originally went with the stock Ground Control setup for sedans, the rear had WAY too much travel, and I had hardly any adjustable range left on the rear height adjusters. With 5.5 inch long, 475lb/in rear springs, I had to have the collar all the way to the top, and a 12mm spring pad just to keep the rears from tucking. 1 passenger in the back would cause my wheels to scrape the wheel liners.

Ended up getting 6.5 inch long, 550lb/in springs to keep the rear in check.

Even if a touring doesn't weigh more than a sedan, it's weight distribution is completely different with respect to the rear axle. Way more of the weight in a touring is all the way in the back of the car, several feet past the rear axle. This creates a much larger moment for the springs to counteract. A good portion of the rear weight in a sedan and/or coupe, is directly above the axle.
