kyb agx is not recommeneded for the h&r race springs
koni yellows or tokico illuminas would do a better job

 

Coilover sleeves/full-setups use linear rate springs, which have a harsher ride than the progressive rates normally used on your typical set of aftermarket springs.

Shingo

 

Comfort and performance are inverse when it comes to springs/coilovers.

For comfort, spring manufacturers give the spring a progressive rate, which means the resistance increases gradually over compression/tension (easy to compress at the beginning). A lot of coilovers have linear rate springs, with performance in mind, which means the force increases at a linear rate as they are compressed/tenssioned; force is proportional to displacement.

This means that bumps in the road will cause the easily compressed progressive springs to react, where as the linear springs will not; for this reason linear springs give a harsher ride.

Of course, linear springs will be stiff from the start, so if you're making a hard turn, they're be less mushy and will keep the car flat, rather than rolling.

 

The ITR Rear sway bar is in (thanks Beaks!!), so i'm still debating if i should just stick with the current coilovers, or the H&R Race Springs. Its very likely that i'll just stick with the current set of coilovers, or pick up a set of SPW's new coilovers for relatively cheap (145 for the H&Rs out the door, and 100 or so for the SPW's), they ride nice, and dont squeak. A good friend of mine from Sacramento is here in LA for some business, and has a 94 Ferio with a set of Neuspeed Race springs and Koni Yellows, and his car is like a truck campared to mine, although the ride is smoother, but not that much smoother. It was although, virtually squeak free.
