I was wondering if anyone has compared the different available LCA busing options?

From what I can tell the current available options are: OEM RCF bushing, Figs and RR Racing. Which of these are generally considered the best option for our cars? I'm considering the RR Racing, but am a little worried about the potential harshness. Does anyone have fist hand experience with aftermarket LCA bushings?

 

Define best.

There's lots of info for this on other cars. The same would apply to us.

Lot's of info. When I had my ISF I ran the RR Racing bushings. They were GREAT IMHO

 

The best LCA bushings are the LC500 bushings because they have "LC" in them. the LFA bushings are also good because they have LA in them. Los Angeles is the best place to buy bushings because it has LA in it. Louisiana is also acceptable.

 

LFA bushings are best as they are mad tyte JDM, yo and tested on the Nurburgring. So they are best.

LC Bushings are softer but more luxurious.

Los Angles bushings will rob you blind. LA (state) bushings are spicy so they should provide hot handling characteristics.

Results may vary. Consult your physician.

 

Ah I was slightly misinformed, thanks for clarifying.

 

Vandetta .. What is the objective are you trying to achieve? The RC F bushings will be the closest to stock when it comes to the driving signature while reducing the inner tire wear. If you are not one to push your 500 to the limit and such, these would be the cheapest option. That is the route I took and I am perfectly fine with them.

The other 2 options you listed are also very good but I wanted to keep things OEM. Some have installed FIGS and RR Racing so you will see that they had good luck with them.

It all boils down to what you are trying to achieve. if you dont feel the LCA are not stiff enough for you stock, then going aftermarket may be your best bet as the RC F are stiffer but not excessively. I wanted to avoid any chance of NVH at all cost.

 

I read the threads posted earlier in the thread and ended up going with the Figs. My concern was the tire wear issue as well as trying to improve steering feel and reducing brake dive.
Most reviews I read reported negligible NVH from the Figs. I'll report back once I install it myself along with the Swift springs I have on order.

 

Good idea to pair these installs together while you already have the suspension apart. From what I've seen though, installing springs is not easy. Good way to break your hands if you're not careful.

 

THe front springs on this car ride over the strut, so it looks like using the spring compressor is in order. The rears look easy though as the strut and spring are separate. I don't think you even need to remove the rear seats or anything to change the rears.

 

Doing both makes it harder to isolate what mod cause what change in characteristic but the additional labor may not be worth the data you personally gain from doing one mod at a time. Lowkey thought of doing the same pairing.

 

The springs will make the car stiffer, and the LCA bushings will reduce camber changes during braking.

 

camber or toe?

 

Toe, they help prevent the tire wear issues.

 

Usually you’ll get more negative camber (and inner tire wear) by lowering the car. But less inner tire wear with a stiffer LCA. It’ll be interesting to see if these 2 opposing forces makes it better or worse.
