I'm considering getting the Ground Control coilovers, but I was wondering...are they the same coilovers for the 90-01 Integra and 92-00 Civic, or are the spring rates different?
http://www.ground-control.com lists a number of different combos for the integras and civics on thei "applications" page, but none of the part numbers are the same in the for any equivalent chassis (save the acura TL and CL), and I assume these are all the custom spring rates/lengths...however, they do have the same listing for the 90-01 Integras and 92-00 Civics on another page...

basically...will the springs for a 90-93 Integra work on my 93 Civic EX Coupe, since my buddy has a pair I can get for cheap? Will the spring rates be different...drastically different?

 

I am running the 89-91 civic springs on my 92 cx but the spring rates are all wrong.
If you don't plan to do any racing and the price is right they should work.

 

Well, that's a bummer...I only want them for racing (that's why I'm going with a coilover, as opposed to just springs, so I can lift it some on the road)...so, what is the deal with everyone selling GC springs (especially on ebay) that are supposed oto work for the 92-95(00) civic and 94-01 Integra? Will these have the same rates?
Thanks

 

spring rates are a tuning tool to help with oversteer and understeer, same as swaybars. You can order different springs form ground control, call them and they will give you an idea of what you need, do a search on spring rates in the autocross/road race forum. Between those sources you should be able to find the info you need.
