H&R 29800 and Bilstien Sports opinions

[Martin Kuetzing]

Here's the data I got on the springs:

Springs:

Eibach (949.752.6700)

M/N        Appl.         "Spring Rate"               Lowering Amount
(200-20V)

1506.140  '91 100     Linear         F    128#/inch      1.0"   (1.25")
                      Progressive    R    128-286#/inch  0.8"   (1.0")

1529.140  '92 S4      Linear         F    246#/inch      1.0"   (0.75")
                      Progressive    R    188-308#/inch  0.8"   (0.5")


H&R  (888.827.8881)

M/N        Appl.         "Working Rate"              Lowering Amount

29800   '91 200-20V   Linear         F    175#/inch      1.5"
                      Linear         R    230#/inch      1.5"

29616   '91 100       Linear         F    175#/inch      0.75-1.0"
                      Linear         F    200#/inch      1.0"

29921   '92 S4        Linear         F    300#/inch      n/a
                      Linear         F    350#/inch      n/a
  He said:  "don't even try the 29921 on a '91 200 20V!"

Please note that Eibach and H&R use different means to publish the spring
rates for their springs - that is, the listed rates are not directly
comparable.

I'll be interested to see how Chris Miller likes his Eibach-front and H&R
rear-combo.

These numbers are from a post a while back.  I hope they are right, I
suppose a call to H&R to confirm is in order.

H&R spring rates
200 20v springs  #29800 220 lb/in F 310 lb/in R
V8 Springs #29921 300 ib/in F 330 ib/in R

Brian-
Do you have #s for the spring rates of the 29800, the V8 H&R and
your Eibachs? I'd love to know what the differences are.

Thanks for the reply Taka,
I think I was a bit surprised by the amount of body roll with the H&R's.

 As I said I have stiffer rear springs on my 20v and the body roll is
much
less.  I am starting to think a rear roll bar isn't really necessary,
maybe
just stiffer springs in the back will make a big difference in reducing
body roll without making the ride too much worse.   I wonder if the
optimal
set-up would be a H&R kit with the 200 20v front springs and the V8
rears...

Neither my stock front eibach rears or the H&R's both with Bilstien
sports
seemed underdamped over bumps (my bumps may differ from yours).

???

Plush? I have that setup and it is far from plush- the springs are quite
stiff, takes quite a bit of force to really compress the springs.

"Snip"

Biggest problem I have is the body roll- even with the Bilstein sport
and H&R springs the car rolls like a big boat when pushed hard. Only
thing I can think of to combat this would be to put a large front
anti-roll bar on the car and a rear bar to combat the corresponding
understeer.

I think the shocks are more of a problem than the springs- the shocks
need more rebound damping so the ride doesn't get ridiculously jiggly on
short
bumps- our
A4 w/ H&R coilovers rides better in that regard, although the shorter
wheelbase makes the car less comfortable, but the shock damping is much
better in that setup.
