Anyone have em, or familiar with them. Most feedback I've heard is they retain stock ride better than any spring (non-coilover) available. Any opinions? Other than not to lower it at all!

 

almost everyone who has used kg/mm springs has a favourable impression of them

the ride quality is very good, it doesn't have the harshness typically associated with lowering springs such as H&R. at the same time, they perform very well

 

Thats what I heard. Buyer beware. Nuespeed springs are awful.

 

kg/mm is a spring rate, identical to lbs/in. It is a measure of how stiff the spring is, not a brand or type. For instance, if you compressed a spring with 400lbs of pressure and it compressed 1 inch, your spring rate is 400 lb/in. Same for kg/mm.

 

He is referring to the Japanese spring manufacturer called KG/MM sometimes also called KGM

 

Interesting, that easily leaves room for misinterpretation

 

I have them in stock, contact me at chris@bulletproofautomotive.com

Thanks

Of all the aftermarket spring, kg/mm is the best you can buy (beside coilover set). And the DR line is the way to go. It combine two spring into one. ride is extremely good, but when you push it, it will never disappoint you.

 

I have them and they ride really nice. Very close to stock. Using them with the OEM struts and can't complain. Get the DR-21 Race Version, that is what I have.

 

They make race and a sport spring. Whats the drop on race?

 

Here is how an Ap1 would look like with Kg/mm DR Racing springs+OE dampers w/ 18" OZ Superleggeras...
