I want to lower my car while also stiffening up the drive a little bit. The two coilover brands I'm looking at are RR-Racing and RS-R, but I've read that sometimes these coilovers have issues like sagging or just looking unbalanced. Does anyone have any preferences or any advice?

 

if the coilovers sag, you just adjust them to raise which ever is sagging. different from springs where you are screwed if they sag. i have the rsr active coilovers on my 500 and they are pretty good

 

LEMS is another option for coilovers also BC Racing releasing DS-Series for the IS500 according to Figs Engineering's site

 

You're probably thinking of the lowering spring options. Coilovers are height adjustable. There are virtually no real world reviews of any of the (very few) coilovers. Now that these cars are available in Japan, hopefully we get a few more options. The lack of aftermarket support for these cars when it comes to suspension options is really disappointing. I had KWs on my last 2 cars, I am hoping they eventually bring set of V2s to market, but at this point it doesn't look likely.

 

I spoke to KW, they have no plans on developing anything. They said if we could find 10 people and a local car they would develop a kit and waive the R&D fee.

 

Did they mention if they would be AVS compatible? If so, I'd be interested.

 

they didn’t mention. But would be great if we could get a group together to make this happen

 

Too bad. 10 people could be a possibility if we could get the people in the facebook groups involved, but doesn't seem like too many people are looking to go the coilover route. It's all guys asking about which exhaust is best

For me, not a factor at all. The range of adjustment on the stock system seems very narrow anyway. I don't even need adjustable dampening, just a properly engineered set and forget coilover that will ride reasonably well, last, and be dead quiet.

 

Our best seller is RSR and we have no issues with them! Got them in stock too if interested.

The new R3 Road and Track coilover for IS500 has turned out to be a hit. We are selling them all day long with only good feedback and no issues at all. There is a wide range of dampening and a range of springs rates to choose. Between those two things you can really dial in the perfect ride and have the right performance all around. On top of that, we discount the USRS LCA bushings to $300 with the purchase of Coilovers. I believe with both items and shipping you are still under the price of the RSR's. The review below was left by an IS500 owner.

@RRRacing What are the minimum and max lowering amount for the coilovers? Every coilover drops the car too far in my opionon as i would want a more subtle drop along the lines of the swift does with the 1"f and .6"r drop.

 

Most folks drop right around 1", they are totally adjustable to whatever you want. For those lowering beyond 1.5" or so let us know and we can set them up specially for that setup when we build them.

When running coilovers that are not AVS compatible do you get any warning lights or messages on the dash?

 

I wouldn't mind a set from rr racing. I wish KW or Olins would fabricate a set. nothing against RSR as they keep the use of the AVS.

 

No lights or messages.
