I know you need the koni specificied ground control coilovers for the koni yellows, but what about the koni reds?
Do they use the same ground controls as the yellows too?

 

The "reds" really won't accommodate a stiff spring rate, such as used in GC kits. They're really only OEM replacements, but can probably handle mild lowering springs.

If you want to use stiff spring rates, use appropriate shocks.

Apologies for not knowing the answer to the specific question asked.

 

No problem.
Anyone know the answer to it?
So from what TunerN00B says, the ground controls off the Koni Reds are probably not the Koni specified Ground controls?
