RSR struts - why?
What makes RSR-type struts better than standard struts?

RSR struts have a raised spindle from what I understand....I think like 19mm higher, so that you can lower the front end and still align to spec. I'm not sure about other features.

dd74, as Mike mentioned, the spindles are raised on the RSR strut, and there are strengthening gussets welded to the tube portion of the strut as well. The body of the strut (tube) is also fully threaded to allow coilover hardware to be used. Doug

Here is a picture:
 They include all the differences listed above. But the real difference is the threaded body to accomodate coil overs. You can do the raised spindle and gusset mods to regular struts.

I have the 'RSR' struts on my car - with JRZ dampers.
They allowed me to have 2 1/2 degrees of negative camber up front; I was lucky to get .50 & .75 with the factory struts. BTW, great for track use - but not at all needed for street... Here's are 2 pics from my site: http://www.rennstore.com/content/00/01/28/25/63/userdirectory46.content/234857.vmg http://www.rennstore.com/content/00/01/28/25/63/userdirectory46.content/235277.vmg Craig RS |

You can get -2.5 camber with regular struts too. You just need to have a strut bar that can act as a turnbuckle to bring the towers closer together. I could run up to -3 using this method. All my other suspension parts are stock as per my racing class.
Cheers, James

James, camber range is largely a function of ride height. Lowering the car (to a point) enables more negative range. Cars at the accepted "euro" height typically max out around 1.5 degrees negative.
The turnbuckle works, but you have a practical limit set by your diminishing hood gap. Realistically you might get .25 degrees out of that. I beleive the RSR struts are also decambered 1 degree from stock.

Yes Chuck. I forgot about that. My ride height is 23.75in front so that helps. Unfortunately, RSR struts are verboten in Stock classes(PCA racing anyway) so you end up doing some "creative" engineering to get the settings needed for R compound tires.
