hey guys, i am about to buy the BC Racing coilovers and i see that they offer multiple spring rates. 10k/10k 10k/12k and 12k/12k. is there a big difference between 10k and 12k if i do 10/10 or 12/12? it is my daily driver and i like ripping corners hard and am looking into some track days or auto x in my area soon. how would the ride differ from 10k/10k vs 12k/12k. my current wheel setup is 17x8 17x9 +45.

 

since it's your DD, I'd go with 10/10. 10/10 is perfectly fine for the occasional autox/trackday.

 

10/10 or a 9/10. But I would go with a 10/10.

 

I would go 12/10 if you don't have a big front bar

if you look at the spring rates on this car you definitely want more spring up front
thats what they did with every year except 00-01 and you can realy see with the CR rates

 

When would you want to go with 10/10 vs 10/12 or even 12/10?

hypforlife32, which did you go with? review?

 

i went with 10/10k. I received them last week but don't have an S to put them on at the moment. I am just waiting for my car back from the shop to throw these baby's on.

 

what are the stock suspension spring rates?

The information in the following thread is much better in my opinion. The spring rates were calculated using common engineering spring formulas, and backed up with physical testing.
