Has anyone looked at rear sport bike shocks for the front end of their car, particularly inboard systems?

All,
Has anyone looked at rear sport bike shocks for the front end of their car, particularly inboard systems?

There was a big discussion on the Yahoo Locost list about a week ago.

What kind of shock is that in your picture? I've bought a couple of similar Yamaha R6 shocks (plentiful and have been/are being used by a few
builders already). Presently shopping for a couple more for the back.
Steve Graber is using them on his one-off "La Bala", and I plan to copy his pull-rod system in
the front. The back will have to different, though, and I am presently planning IRS, probably with a shock box or rack on top of the differential
cage.

The picture above is of a yamaha r1 rear shock.
After the talk about using a bike shock and inboard system any thourts on using bike callipers and disks also mounted in board on the rear end.
Don't know about using bike brakes on a non-BEC. Seen it done on some hot rods though with regular calipers.
BTW, just paid for a pair of yamaha r1 rear shocks (2002-2003) from ebay, $69.50 (with shipping). Yeah!!

Just won my third 2002 R6 shock! 
Should have held out for R1 or 2003 R6, though. They have a nicer finish, I think.
For the uninitiated, these are some damned nice shocks. Adjustable in compression and rebound (separately), gas monotube, and aluminum body. Cost
new is about $500 each, I think. The reason they go so cheap is that the hotshots are upgrading to a yet fancier brand (Penske and Ohlins).
So, Cory, have you had a chance to do a little more research yet? Got any specific concerns?
Do you happen to know the spring rating on the R1 shocks? The R6 are 543 lbs/in, and one nagging concern I have is the force that they will exert on
the chassis. 2-3 times a normal shock load.
Blake, I'm sort of ignorant about bikes generally, including brakes. Stopping power ought to be fine, I suppose, if you use gear from a
high-powered bike. Haven't a clue about what sort of master cylinders to use, etc. It seems like a good idea, though. Don't talk about
it too much or I'll be wanting to use bike brakes, too, and my complication level is already high enough, thanks!! 
Hey Pete,
Do not know that much about the R1 coilover except the length and travel is what I am looking for and the price is right. The spring can, and likely
will, be swapped out for one that will be closer to my needs. Also, these can be revalved by Racetech. With new springs and revalving, I will still
come out way cheaper than going for a set of rebuildable Penski or Bilsteins.
I have built my front end out of 1X2 0.083 wall tubing to handle (I hope) the forces generated by this setup. See my photo archive for current status
of frame.

Truly, in this Locost thing you learn something new every day. Revalving never entered my mind, and momentary I thought, "If they can be
revalved, then I don't have to foll with inboards"! Then I remembered the gas reservoirs, and it wouldn't do to have them hanging out
there in the breeze.
Does Racetech have a standard price for revalving? I am planning on just reducing the effective spring rate by using approx. 2:1 (front) and 3:1
(rear) leverage ratios in the shock linkages. In this case, the original springs and valving can be used, though heavier-duty mountings will be
needed.
I think I'll check out Racetech, but will probably opt for the Locost route and use as is.
Thanks!

Hi, just to mention there are a number of bike shockies that have external reservoirs with rubber hose connection... Can't name them off-hand though. Re-spring those and you could use them outboard.
(HOWEVER... IMHO - the pullrod setup looks 'cooler'. Which is reason enough to use it anyways!!!
Graber
Your setup looks the dog's bollocks, as they say. I'm just a tad
nervous about taking on IRS. Not the geometry so much as the structural part. Thanks Pete, I'm sure there were others before me... I just talk about it (A LOT! heheh)
BTW - I have been driving my car 'round the block, fast enough to powerslide around the 90's (don't tell the wife) , and the shocks
apparently work great. There are some deep-ish concrete drainage channels across the intersections that I am taking at about 40MPH and the suspension
is supple, not jarring at all.
Good thing you have some broad-minded neighbors!
Do you have a manual that tells how to adjust these things? Certainly not an urgent matter at my stage of the build , but I'm curious.

Oh, geez, I love the way the Brits talk. One of my favorites is, "Can't be arsed". I use it all the time.
For cultural reference, the equivalent of doggie danglers that I grew up with was "the cat's ass". Interesting contrast.
here's something that may come in handy for LB readers:
