Reply to "Shocks/coilovers"

There is a lot of discussion on this board about the QA-1s. Apparently the stock number of the shock has changed....

NOTE: I have been looking for shocks for a Narrowbody Car.

OTHER NOTE: I am not advocating the QA-1s - Just reporting on what I have read.

My discussion and research shows there is a general consensus on the 11.6" (Compressed) and 17" (extended shock length), using a 12" spring - but there are some who suggest I consider a shorter shock, and a shorter (10" spring). Right now, I am trying to decide on Wheels and tires - shocks and springs will then follow.

There is also discussions about the spring rates - it seems that some (many?) setups are much more heavily sprung than the stock rates. Anyway - there is much information on this board if you search.

I would be interested in what you find.

All the vendors have "engineered" spring and shock packages. Dennis Quella has a Koni package - recommended (or would have been) by Carroll Smith.



Here' s some of the data I have found....
