RE: [DML] Re: Eibach springs/shock set




Thank you Kayo for posting your observations on our, and DMCH's, suspension
system. For those of you who don't know it Kayo is an authoritative source
for info on these kits. He has driven many hard (brutal in the winter with
car swallowing pot-holes) New York City and highway miles on our suspension
and pushes his car harder than the average enthusiast. He is good at
deciphering small changes and improvements and so I've often used him as a
highly intelligent "Guinea Pig" for checking performance and longevity of
our and Houston's products.

As some of you know we no longer offer our shock kit mainly because of a
drastic price increase when we went to re-order another batch a couple years
ago. We have been selling Houston's kit for some time now and are happy with
the results. Unfortunately DMCH got hit with a similar price increase
recently from their supplier because of "insufficient production volume" but
I've decided to stick with them to help avoid further price increases. Each
setup has its own advantages but sometimes it's more cost effective to stick
with one setup at the expense of more choices.

As some of you have correctly noted our shocks do provide a more comfortable
ride than either the stock or the Eibach spring/shock kit but therefore
allow more body roll when cornering closer to the handling limits of the
car. Either setup handles far better than the stock setup due to lower ride
height and updated internal valving. 

IMHO most European's (like Martin) will prefer the firmer DMCH setup while
many American's would prefer the more comfortable but slightly less tossable
handling our kit provided. Alas it just wasn't ultimately cost effective for
each of us to offer separate kits so I deferred to the DMCH kit.

We had experimented with hybrid installations between the two kits and don't
think it's necessary to advise against the combination of our front springs,
which we still offer BTW, with DMCH shocks or Eibach springs with our old
shock setup. I think Mark Levy is still using that combination and may wish
to offer his input? They were similar enough to be interchangeable in my
opinion. However I would advise against combining different shocks due to
internal valving differences. My personal favorite at this point in time is
DMCH shocks with our front springs which still allows the rear to be lowered
and is less expensive than popping for the Eibach springs. Hopefully Steve
and James won't be too miffed at me for letting that slip as we've been
getting along famously these days:)!

Hopefully this has resolved some of your questions and concerns.

Rob Grady,

FWIW.... I had the front and rear shocks as well as the front springs of PJ
Grady in my DeLorean for many years and with over 80,000 miles or more.
This 
combination handled and rode well and they were ready for replacement.

Recently, I had heard so much as how great the DMCH springs and shocks
combination was.  I wanted to see for myself if there was a difference of
the 
DMCH's system versus PJ Grady's system so I had the DMCH complete package of
front and rear springs and shocks installed two months ago by PJ Grady.

My findings to my DeLorean, is that after the DMCH system was installed, the
rear sat way too low and cause the two rear wheels off to be off camber.
The 
rear wheels was doing a split and causing a slight premature wear to the
inner tire.  This situation also causes the rear end to sinks under hard 
acceleration.   I believe that this is where upper or lower adjusting
control arms are necessary to help correct the camber condition. The other
situation was 
that the DMCH front springs are lower then the front "sagging" springs of PJ
Grady's that they had replaced and with the passenger's side about a 1/2"
lower 
then the driver's side.  With all of these conditions, the standing height
was not visually right or physical correct, although the DMCH system is
correctly 
installed.  The DMCH's system ride was also a big disappointment.  Handling
was not very good on turns at higher speeds for the rear was sliding out on 
tight turns causing sway and the ride was generally bumpy and hard.  I
couldn't believe that this is the ride what everyone is bragging about?

Two weeks ago I've taken my DeLorean back to PJ Grady to have the rear shock
adjusted to a higher setting with the rear driver's side adjusted a 1/4"
higher 
then the passenger's rear shock.   This adjustment had made a BIG difference
in the standing height and also correcting the condition of the camber, as
well 
as the ride and the handling ability of the DeLorean -- Offering a total
major improvement in the ride.  Now, it "rides on rails" like everyone
claims.  So, the 
DMCH's front spring and shocks are excelling in handling and offers a "good"
general ride.   

IMO, the PJ Grady's front spring and shocks offers a more comfortable ride
although a bit short in handing as compare to the DMCH's system, but this
can 
be due to the original OEM rear springs which prompts the rear to be higher
then the DMCH's rear springs.  

As of now, the DMCH's system front springs in my DeLorean are not
symmetrical in height as they should be with the passenger's side being
lower of 3/8" 
to 1/2".   I don't know the reason for the differences, for maybe the
springs have a different compression rate or the well housings maybe
different in 
dimensions?  I do know that my frame has not been in an accident as to cause
the differences.  Rob said that he had installed several DMCH systems in 
other DeLoreans and have gotten better results for they were correct in
their standing heights.  Rob suggested that shims could be fitted to the
front 
springs of my DeLorean as to help raised the front and to help the ride.
Rob also suggested driving it for a while until they "settle in" and when he
gets the 
shims made up, the shims will be installed to correct these situations.

So, until the shims are added. The ride of the DMCH is still worth the
money so far and they do feel like the DeLorean is on rails.   Personal, I
still like the 
ride to be softer and I believe that the shocks of PJ Grady may yield that
effect if fitted with the DMCH springs.  I wont know until they are
installed in this 
combination in the future.

For reference, I have the standard OEM rims and the correct sizes of
Michelin Pilots tires for the front and rear.   Oh yes, on tires, I like the
Pirellis slightly 
better, for they are quieter.
