The Swift assist springs will be installed and used with my BCR coilovers.

This is what got from their site..Directly from Swift

"Assist springs have two functions. The first is the spring adds a progressive rate to the initial portion of the stroke. This progression can add increased comfort is used on a daily driver coilover setup that has stiff springs installed. It provides racers added softer spring rate progression. Once the assist crushes, the normal spring rate will take over.
The second job is the same as helper springs. They prevent the loss of traction during rebound, and extreme cornering."

But, one thing i notice is that the rear Coilovers does not have room to lower much, if i install the assist springs. I've talked to a rep at Ravspec and they said to compress the assist springs as much as possible. So i'll be trying that once i get everything installed. Pics are my BCRs. take a look and you will notice that the rear does not have much room for adjustment if the assist springs are installed..

As for the plastic cover when installing my Strut Tower brace. I had to remove them. You will need to do some cutting to get them back in. i'm still debating if i want to do that to my OEM side covers. I'll keep everyone posted on how my car handles after all is done.

take pics of the swift springs installed with the coilovers please

 

Mly916 answered my question, I figured that you would loose the side panels unless you mod them. I know in the IS300 with some stb's the clearance was tight so some stb's would rub/vibrate on the engine cover. Atleast for me it was during idle that I would hear the vibration but once moving it went away. I like the beefy look of your STB though. I think I want to upgrade my sways first. Does anyone one know if they make f & r under braces for our cars?

 

Yes.. Lexus F-sport makes front and rear sway bars.. I've them and they look beefy. Much thicker than stock...

 

Would the strut tower brace clear a K&N intake on the GS350? Very interested in getting a strut tower brace

 

would the STB clear a gs460? i see your in cali, so if you are close by to orange / la would you mind if i check it out?

 

bump for any updates from op or any other member that can contribute?

 

Megan strut tower brace on '06 GS300

 

That megan bar looks clean. Is that the is350 bar installed on the gs? I want to purchase one but want to confirm that the is350 bar fits the gs.

 

@ Kliner: yes it does

 

Thanks jaguar, i just ordered mine.

 

the rear suspension for the AWD is the same as the RWD GS350 correct? i want to order the Megan control arms set but they list them as fitting 'RWD models only'

 

Hi, That looks great. I presume you had to cut the plastic covers to fit both ends of the bar. Was that hard to do and can you share how you did it?

Thanks,

 

i used a dremel to cut mine out. Works pretty good and you can round off the edges that way.
