I put this combo on my car a couple years ago...one difference for me, vs
the typical H&R install, is that I used the H&R spring intended for the
V8. The V8, naturally, is a heavier car than the 200q, and the expected
result was slightly less drop than with the 200q20v springs or than the V8
springs on the V8. Did I get what I expected? Yes. H&R claims 1.2 to 1.3
inches of drop for the "correct" V8 and 200q installations. Add back about
0.25" to 0.5" due to the Bilsteins, and you have somewhere around 0.75" to
1.0" net drop. I didn't want even that much, though. My net result was
about 0.5" drop up front and .625" drop in the rear, measured from wheel
cap center to the top of the wheel-arches.
Subjective results: I love the handling :) and find the ride
acceptable. My wife hates the ride. (her comparison points include her
RWD Volvo turbo wagon which she loves and my folk's '92 Audi 100s FWD which
she likes even more; her complaints may also be with the much higher
steering effort level required to work the car). Oh well. The ride is
definitely firmer--even harsh depending on what types of bumps you
hit. Sharp inputs, and the compression damping is too aggressive up
front. Low frequency/long pitch waves, and the rear rebound damping is too
mild. Remember that I have a mismatched spring to this car, though.

The issue isn't so much lowering the type 44 makes it understeer, but
lowering any car with a MacPherson strut front suspension can quickly
destroy the suspension's geometry. Two distinct but related issues include
changing the car's position on the camber curve for your new "normal" ride
height and introducing (exacerbating) bump-steer. The latter could be
easily fixed by raising the steering rack as much as you lower the
car--alas, this simple fix doesn't work on our cars. Too low, and you may
not be able to achieve stock camber settings--OK for the track, but
problems on the street.
Brett mentioned someone complaining about "setting" the car in a
corner. That may well have been me. I installed this spring/shock
combination on my car almost three years ago. At the time, I had only the
stock 15" BBS rims, shod with Dunlop D60A2 tires. The problem with this
setup was that I now had the tires working much harder than before, as they
were the weak link in the system (too small, too much sidewall flex, too
tall a sidewall). As a result, unless you drove the car aggressively, the
car would not set in a corner, and the constant fighting back and forth
between the springs and tires made the car seem nervous. Within a year, I
had 17x8" BBS RX rims shod with Dunlop SP8000 (235/45-17). This brought
back a balance between the tires and springs, and the nervousness in
cornering disappeared (but now you have to contend with grooves in the
pavement and even more tramlining than before).
FWIW, I wrote a short article about this (doing the suspension before
bigger tires) in the NWRAQC's newsletter last year. see here >>
formatting is awful, but you should be able to figure out what I was saying :)
Finally, Larry Leung mentioned a 200q 10v--just remember that your car is
even lighter than the 20v cars, and a significant part of that is in a few
chassis/suspension point reinforcements. You won't be able to make direct
comparisons with a 20v car.
