Our “R2” coilovers have been a huge hit in the Lexus community for the past 3 years, but never leaving well enough alone, we have been hard at work listening to feedback from our customers and making our coilovers even better. Allow us to introduce the RR Racing “R3” coilovers. For the first time, we are able to offer a coilover suspension that is 100% custom manufactured to our specifications and requirements, without compromise. Our R3 coilovers offer the following improvements and features:

  • Ultra Digressive shock piston technology (see attached chart). Digressive piston valving allows us to achieve relatively stiff shock settings at low shock speeds, and relatively soft settings at high shock speeds. This means that the car will feel extremely responsive during cornering, but compliant when hitting bumps. Also, changes in shock settings will mainly affect the cornering response of the car rather than the harshness when hitting bumps.
  • Swift springs available in wide range of CUSTOM spring rates tailored to how YOU drive your car, we can do anything from street comfort to track setups.
  • Lighter weight compared to R2 coilovers, approximately 2-3lbs lighter per shock, depending on application.
  • Adjustable shock dampening with a wide range of adjustment for meaningful changes in the ride and handling characteristics of your Lexus.
  • Every coilover leaving our shop is pre-set for optimal lowered ride height, only minor adjustments are necessary upon installation
  • We also offer one-on-one consulation at no additional cost – If you have any doubts on what spring options to order, please call us prior to placing your order to talk to one of our suspension experts.

We highly recommend to install our Ultimate Steering Response Product (USRS) in conjunction with this suspension to improve your steering response (offered as an option to this product).

ISF coilovers
Did the 14/16k with the control arms. Feel firm but nice. This pretty much completed the car. I have all the RR racing bolt ons. If I decide to supercharge it, it would probably feel like a race car.

Great for the daily
I have a 2011 ISF and when I installed these the ride felt amazing, way better than the oem suspension, I’m on my stock wheels and I have a little less than 1 finger gap after lowering my car and the car ride feel way better than when I had oem suspension, my spring rate is 14/10, for the price well worth the money!

Amazing Coilovers
I don't normally leave reviews on things but these Coilovers are incredible. I have a 2012 ISF that these completely transformed. I got the Road and Track Plus spring rates and have zero regrets. The ride comfort is even better than stock with the default dampening, and the cornering capability is on another level. So happy with this purchase and can't wait to take them to the track.
