Coilovers -- was Re: [s-cars] Installed the HRSB

Of course one big advantage of coilovers is being able to adjust height for summer and winter driving but then you need to redo your alignment each time you change the height adjustment.

The only company (that I know of) offering coilover packages for the UrS-Cars is 2Bennett: http://www.2bennett.com/body_type44suspension.html They offer rear only (Street Sport system) or full 4 corner coilovers... 

I see less of an advantage with rear only coilovers cause you're stuck with one height, but I guess it offers you the ability to have higher spring rate in the rear. The only disadvantage with the 2Bennett full coilover is they use an open bearing design that requires servicing.

Another source for coilover parts to build your own:  http://www.ground-control.com or http://www.ground-control-store.com/

In principle they don't differ from the stock coil suspension in that coilovers are exactly that - coils over shocks.  

The difference lies in that "coilovers" have threaded bodies to allow height adjustment by raising and lowering the lower spring perch.  Typically coilovers use 2.25" or 2.5" I.D. springs all around, so the front springs will be much smaller in diameter than stock.  And there are literally 100's of different spring rates and length combinations you can readily get.  

They're really designed for race cars where you might need to constantly change spring rates depending on which track you're at, or weather conditions.  

If all you're trying to fix with coilovers is a potential rubbing problem with the HRSB all you need to do is pick up a set of slip-on threaded sleeves for the rear shocks and set of appropriate springs.  These sleeves allow you to turn your shocks into an adjustable "coilover" and will fit right over the Bilsteins, which have a removable lower perch.  A pair of sleeves and springs can be picked up at automotive swap meets for about $150 or less.
