Ok guys when I bought my em1 about 2 yrs ago it was completely stock except for a drop. The suspension consisted of ground control coilovers and tokico illumina gas shocks. The ride was pretty good but I'm wanting to upgrade.

My question is if I don't know my coilovers spring rate can I find out somehow. Also where have yall found the best price for koni yellows and does anyone know the product number. If I am confused about something please correct me. Thanks in advance guys

 

Get koni's and sell me your illuminas.

The koni's are a definate upgrade. And I'm not saying that from wanting your tokico's.

It will be better, but not exponentially. More adjustability, but I'd expect similar feel at maximum stiffness

 

search the road race forum. There's ton of info on Koni's.

 

your also going to need to get different sleeves for the konis with your gront control coilovers, you might be better off just buying a whole new set in the market place for like 900 shipped for koni yellows and ground control coilovers
